Are there any tweeter solutions?
 

Just need some input, looking to get some highs up front.

I bought these Boss tweeters on advice of one of the aftermarket tweeter thread in this forum. $20 and 2 hours later, my Bose is no longer muffled. All you have to do is solder these in parallel to the Bose tweeters, *after* the filter. Then double-side tape it to the outside and experiment with speakers placement.

No cutting or drilling necessary. You can drill a hole to run the speaker wire through if you want a clean install.

For my tweeters I took the factory off then hot glued tweeters that came with my alpine components. :D:

These are very small high-quality french units that you can epoxy inside the factory housing and in front of the factory bose tweeters. Very stealth, clean and quick install. The factory bose tweeters are well matched to the system, mostly sound great and I didn't want to lose them because of this, BUT like all Bose products, the higher frequencies are cutoff and boosted artificially due to their designs philosophies. You can tap of the factory leads and cap them off at around 6,000 Hz with a 6db slope. I also noticed that the harshness of the factory tweeters were attentuated and the transparency has opened up in this setup due to either 1) placement in front of the factory tweeters buffers the harshness, OR 2) the impedance change is dampening the high frequency boost that Bose likes to design in. Great upgrade for about $25 including shipping...

I plan on reciprocating this idea... My only question is how you capped off the tweeter at 6,000 Hz with that 6db slope? You applied a filter to this specific tweeter?

Also, could you post some photo's so I understand what the final product should look like?

I just got some Infinity Kappa Tweeters and they're SWEEEEET!

i think that on a lotttt of my music, the high's come out sounding really harsh and piercing. I don't like it, not one bit. so, changing the tweeters to these ones will fix this? and i didn't completely understand your point, should we connect the new tweeters BEFORE or AFTER the built in factory filter? will connecting them before (without) the filter cause them to blow, or is this filter not required.... help!

i think the filter just filters out the unecessary frequencies for tweeters...

I'm pretty sure that the reason the Bose tweeters don't hit the high frequencies is because how big the Bose tweeters are... Wiring these little tweets parallel to the Bose tweeters (and I guess placed right in front of the Bose tweeters) will bring out the higher frequencies...

It'd be pretty absurd if Bose cut off the higher frequencies...

i went to tweeter today to ask if they sold any tweeters... lol... and he asked what kind of system i had... when i said "stock bose" he told me that there was no way to change my tweeters because bose is weird...

is this true? why did he say that? can i safely add on the above mentioned tweeter? also, what if i want to replace my old tweeters with the above ones, no just add them.... can i do that?

Aww, man. Listen... you can change ANYTHING as long as you are willing to spend the money and do it correctly. While I recommend changing out the ENTIRE Bose system, you CAN add tweeters to it. As for replacing JUST the Bose tweeters, yes, there has to be a way.

1145 climber, realize that your going to a company sponsored audio expert... emphasis on the company part... These guys wouldn't want to get themselves into the Bose system because, yes it's a little complicated, but their also probably lazy...

Anyway, I've recieved the tweets! And just ordered some highpass crossovers... 5.8 thousand HZ at 4 ohms...

My main question is that when I intently looked at the Bose tweeters, I noticed that the filter on the Bose tweeter is on the green wire (which I thought was the negative for that tweeter), but don't highpass crossovers start on the positive wire? I'm a little confused now... Is the red wire the positive or negative for this tweeter?

When I recieve my crossover/bass blocker should I connect that crossover (and I'm gonna list the possabilities) to the green wire, before the stock crossover? to the green wire after the crossover? Or simply to the red wire?

FYI, before more misinformation gets spread...there are no "Bose tweeters" in the RX-8.

The small speakers mounted on the doors near the windows are MID-RANGE.

ya, that magnet is extremely strong....

so if im looking to buy a set of tweeter's to REPLACE the bose ones, that also cover mid-range frequencies, what exact specifications do they need to have?

So has anybody just replaced the 2" mids with tweeters(and how does it sound?) or has everybody just added tweeters to the 2" mids? I was planning on just replacing for a better look.

I know one specifications is that they be 4 ohm... But I really don't know what kind of wattage were looking at...

I considered using my used SL60 tweeters to replace the Bose, but just today I installed those tiny tweeters (without a crossover) and wow their is a difference...

I can actually hear the higher frequencies (ofcourse), but most importantly is that I can raise and lower the tweeters power dramatically with the treble control

I just replaced the front and the rear "tweeters". I'll post pics of the rear deck to show you how I got mine to fit.

You did? How did you put tweeters in the back, you gotta show us, not just talk about it...

I'm almost done with my audio system modifications... After adding the tweeters in front of the Bose mid's, I can't help my say that the system sounds amazingly cleaner... I haven't even put in any bass blockers for these tweeters, but they fill in the sound so nicely, and if you raise the treble to +6 it brings out the smaller tweeters rather than the Bose mid's.

Other than that I plan on making that bass in my Bose system sound alot real-er... I'm adding an 8" Kicker L7 powered by a Alpine MRP-M450... I'm curious as hell what the bass will sound like... I got all the stuff shipped and bought a pre-fabbed box with a vent :)

treble to +6? are you crazy? do you still have the bose "tweeters" installed?

with the bose tweeters, if i turn the treble up past +2, all the highs in my music are REALLY shrill and piercing.... (for me anyway). it like hurts to listen to... and im forced to turn the treble down to 0 or -1....

also, can you give more detail on how you hooked up your tweeters up front? did i miss it?

If you can find them, a great Tweeter replacement are the Image Dynamics NX30. I replaced my crappy paper-cone Bose tweeters with a pair of these. They are dramatically better. They are one of the few tweeters capable of covering the same midrange as the Bose crappolas. I just removed the old speakers, desoldered the non-polarized capacitors Bose uses as a crossover and connected them up to the new ID tweeters. I had to manufacture simple brackets to hold them in place in the spot where the Bose speakers were.

I also added an Infinity Basslink in the trunk to improve the really weak low end. Now the system is quite acceptable.

can u guys post up some of the best tweeters as well as bass blockers for this application? they gotta be small enough to fit in front of the mids. thanks!

I'll take pics as soon as I get home tonight.

ya,it's really not that hard... a simple tweeter, just look at the Bose mid...

Once I did this install I never really understood how Bose makes their speakers, having a small mid speaker (THAT STRONG) magentically is kinda weird... I was "literally" having a hard time putting the screws back on, because before I could screw em in the magnet on that damn mid would grab the screw...

You just notice how one end has the filter (since I have no filter yet) I just placed that small tweet after the filter and placed the other wire on the other side... Simple... But once I get my filter (which'll be soon 5.8K HZ at 4 ohms I think), I'll tap the wire before the Bose filter ofcourse...

Once I noticed how big that speaker is (for what it is, a speaker)... I realized that the much smaller speaker (tweeter) takes care of the high's alot better than that Bose... The Bose makes High's sound bad! I never used to raise the treble on that system, but now with these tweeters the highs sound so much stronger that the system just sounds generally stronger... I rarely raise it pass 28 with all my rattle's fixed, and these tweeters in place... And like I've said earlier the Bass will be fixed with L7'edge...

But for what this mod is I've have to say that it was the most definate increase of sound with the cheapest price in mind... If anybody is barely interested in increasing the sound potential of the Bose system, this should be on the top... A mere 25 buck job that fills in the sound barrier most don't bother with...

Also, I hot glued the tweeters in front of the Bose speaker grills... hahaha

Hey Jedi where did you buy your speakers?

just ran out to the freezing cold to take some pics for you guys... let me upload them really quick

Since the Bose didn't fit, here was my creative solution to getting some Infinity Tweeters in the rear deck.

I think it looks super clean, what do you guys think?

The beauty is that unless you're looking for them, you don't see them. The headrest does a perfect job of concealing them.

that is very clean too bad you didnt pait them black, it would be very stealth then, but looks great i still cant wait to hear it!

I thought a lot about painting them black but I like the way they turned out so I wanted people to be able to see them if I pointed them out.
With the limo tint on the back window, you can only see them if you're actually looking for them. :)

that does look very clean

EDIT: I installed my bass blockers, the tweeters sound alot cleaner, bass doesn't distorte them none at all

Tweeter isn't a bad place, obviously you didn't go to the one in Dedham where they are familiar with my car.....

I just did what kwolfman did on the small door speakers except that I used Infinity Kappa 10.7t tweeters.

I experimented with various crossover connections:

(1) no crossovers, just a straight feed to the tweeters

(2) the crossovers that come with the Infinity tweeters

(3) Bose crossovers that come soldered to the Bose speakers.

I settled on the Bose crossovers. I just desoldered them from the Bose speakers and put them between the feed and the tweeters.

The result isn't perfect: there are times when the sibilant level is a little too strong at the level of high end gain I like. But the fix is cheap (about $80 for the pair with shipping from Discount Jungle), relatively easy to do, and results in a much cleaner, tighter sound all around. Also, I personally had found the Bose system very tiring to listen to at moderate to high volume, especially with some voices. The new sound is much smoother and easier on the ears.

I used the "starfish" mounts that comes with the speakers and mounted the tweeters where the Bose speakers had been (behind the grill) so the car looks no different. There are two levels of mounting holes on the starfish. I used one low level hole, screwing it directly to the door panel. A high level mount lined up exactly over the other mounting hole so I used spacers there. The starfish mounts are designed to snap off easily so that you can remove the mounts that aren't needed or that get in the way.

One word of advice: be very careful when handling the wires to the Kappa speakers. They are only soldered on to small terminal on the back of the tweeters. Three of the wires broke off while I was fooling around with the mounts and I had to resolder them.

Thanks to Spin9 for advice on installation.

what would be the best bass blocker or filter to use if i completely replace the bose mid-highs?
i'm installing the boss TW-15's. I'd like to kill some of the overpowering mids in the stock system. the center channel should provide enough mids which is why i plan on getting rid of the mids in the doors. the tweeters should really fill out the system.
any opinions on how to filter them properly???

Here are some pics...

When you add some highs, your mids will probably not be overpowering. It just seems like it now because there are no highs.

same thing I did I think, but I put the tweeters directly in the center instead of on the side...

I replaced the bose tweeters with focal and used the bose cap as a crossover, I suspect the slope is tpp high for the focal since it is rated down to 2000Hz. Any idea how much cap should take to go to 4000-5000? My sound is vastly improved as it is.

I like how you guys are developing some good stealth solutions to adding tweets!
The 2 way mid-tweet looks sweet - I might just have to do an upgrade on mine :)
with these ideas in mind - Keep up the good work...

Update on my Focals. I checked the specs and these are 6 ohms. The Bose cap is 22uf which would give you a xover of about 2000 or less. So I replaced the cap with a 10uf so as to get around 2500. The Focals are rated down to 2k. Wow! the sound is incredibly better, even the bass from the doors sound better, amazing for just 99 cents. With these Focals you do not need to keep your stock "mid" Bose, they do it all. I just drilled out the sail panel and epoxied the Focals for a flush mount that looks stock except for the Focal logo.

i received a set of boss tw20's rather than tw15's. i guess the vendor ran out & threw these in for me. anyways, they have a higher range starting at 5k. so, i'm going to wire them in & keep the stock bose 2" behind them just like the pics posted here. i'll keep you guys posted!

Hey Razz, don't know how I missed your post, sorry.
I got all my Infinity speakers from www.ikesound.com

question for slick8...
how did you manage to glue the little tweeter in there? i can't think of a way to glue it on without having it's rubber surround touch the surface of the bose sail grille. i need a way of securing it in there...

ya, I have a pretty complicated question... Doesn't adding on a seperate tweeter change the ohm'edge??


I replaced this little set up with 2 Boston Acoustics SL60's and the crossovers that come with them... The sound is ALOT better... Just so clean... And since the SL60's run at 4 ohms, I know that the 9 inch Bose speaker will run at 4 ohms...

But either way, doesn't adding that little tweeter change the ohm's too 2?

I used epoxy putty, it's like playdoh until it sets in 5 minutes. I used PC-7 Epoxy Putty that I got from Pepboys. The epoxy putty is available at any auto parts store for $3 to $4. It's also called plumbers epoxy putty, probaby available at homedepot or lowes.

After kneading the putty, I rolled it up into a little ball and then just smushed it to stick after I positioned the tweeter. It's the grey stuff in the pic below. Careful to leave some room to route the wires where the putty should attach.

This tweeter is a poly dome with a protective faceplate and does not have a rubber surround. The protective faceplate presses again the back of the bose sail grill and does not impede motion of the tweeter diaphram.

have u noticed any issues w/ your amp and the impendence change when running these in parallel? i'm assuming the amp is just fine cuz this mod was performed a while ago already...

There shouldn't be any issues with the stock amp and the impedance change when running the tweeters in parallel. Tweeters are efficient and require significantly less power at higher frequency load.

Thinking I can remove the stock "tweeters" entirely and flush mount my Adire Audio Koda tweets in there. I do believe they're 2" in diameter. Think they'll slide right in.... any thoughts?

here you go...a little dremmel tool and I got these really deep 2" Logitechs(compared to the Bose units) in there.

Thought I would add my latest mod here instead of starting a new thread.

Since I mounted my Eclipse 3-ways in the door, I needed to bring the soundstage up a little. After trying a couple different brands, I got a hold of some Rockford Fosgate T1T Inverted Dome Aluminum Tweeters. They blend perfectly w/ my components & they fit perfectly behind the sail pod w/ no modifications. They actually face back a little more than stock.

Right now I have an Eclipse EA4000 pushing the front & rear components w/ the front channel of the stock amp pushing the tweets. Everything (including the stock amp) is being fed through a JL CleanSweep.

Once I bump my doors up to 150w, I will probably have to bump the tweeters too, but for now it sounds great.

But wouldn't the impedance change mean you need to adjust all the calculations for the capacitors? Effectively doubling them to maintain the proper crossover point? (i.e. 22udf must be changed to 44ufd to maintain 1800hz crossover on whats now a 2ohm load).

I am working on adding tweeters and wrestling with determining the proper capacitor I need to protect the new tweeters. Also just the act of adding a 2nd tweeter in parallel would lower the impedance from 4ohm to 2ohm, thereby changing the crossover point on the stock boss tweeter. So don't we need to change the stock capacitor to avoid tweeter damage?
