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.

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!

IMO anything would be better than the bose. Don't forget to add a bass blocker/ crossover, I blew out a nice set of MB Quarts that way. The worst part was I had the cross over, I never got around on istalling them. I added some twenty dollar a pair boss and a focal tweeters, I now have three tweeters per sail pail. Next I need to hook them up to a real amp.

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!

Keef

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?

vdelvec

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.

Keef

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.

Keef

ya, that magnet is extremely strong....

1145climber

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?

RiX-8

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.

Keef

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.

Keef

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

1145climber

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.

dgrx8

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?
