I see all these new modded cars with 2 or more sub woofers inside a box right up againts the inside of a wall. In my opinion this is the worst idea and i dont know why people are doing this. and here are my reasons.
A. I know Bass frequencies are omnidirectional so where ever you point them the sound will spread equally but if u put them in a box or right up on a wall They will
1. have little to no impact as reproducing the sweet tight low end as much as just the rumbly farting type of sound that shakes the poo out of a car.
2. Putting speakers in a enclosed box with the speakers facing inwards IS a DAMN OXYMORON IN ITS SELF they work terrible and have little air to push since there FACING INSIDE. P.S. Speakers reproduce sound by moving air.......
3.What are you trying to prove with 130 db of bass just so u can play your gangsta rap or whatever loud enough to rattle the bolts on your car lose Cmon any 1 else want to chime in good or bad go ahead also please dont take any offense to this its just my semi neutral observation.

 

Most people's ears it seems are accustomed to hearing inferior sound and they think that sounds good.

 

thanks for agreeing as a musician this seems to iratate me more than most people.

 

I do however, wish the 8 had DVD audio.

 

The one thing I would like to correct you on is that "Bass Frequencies" ie low >500 Hz tones have the ability to pass through/around mass and that all car speakers are DIRECTIONAL. Omnidirectional speakers are those that no matter where you point them sound is dispersed 360 degrees. You are right...cars in general are crappy acoustical environments. I mean sheet metal is not the ideal material when you talking about acoustics. However, the first step in deciding what system to put in your car is evaluating the car your putting it in. (i.e....hatchback, SUV, or like the 8 a completely enclosed trunk). There are certain cars like SUV's that completely sealed boxes sound best as opposed to ported boxes. Whereas bandpass boxes are very cheap in that tight bass can't be acheived. Which is what I think you were talking about when you refer to completely enclosed boxes.

Basically my point is that most people don't think about designing a system that acoustically will be the most optimal given the environment it's being put it.

 

I know you thought i just ment boxes with out ports but seriously i ment when the speakers are faced in a PLEXI GLASS BOX not wood wich would let the vibrations out some what naturally It was plex. sorry for the confusion.

 

youre wrong there. it doesnt matter if a speaker faces into the box or not, it will still sound the same as long as you reverse the polarity.


bass is omnidirectional but how you place subs in a trunk will still have an effect on volume.


are you talking about bandpass boxes? if so, theyre supposed to be that way.

 

The whole box is plexi glass??? or wood with plexi glass in the front, which is a bandpass box?

 

JonnyB.......car speakers are not omnidirectional, nor is sound described in that manner. I was simply stating that Subs are Directional speakers. Doesn't matter if the HZ is 60 or 3600 HZ.

 

I'm on the same boat with you guys. IMO, the placement of crazy audio equipment in an enclosed area is worse than putting CF big-*** wings on your trunk door. At least you could actually point out a possible improvement on spoilers. Heavy audio equipment in the trunk gets stupid(er) when these people try to street race. I mean cmon, your car is heavier than when you bought it! hahahah!

 

i didnt say speakers are omnidirectional, i said bass is and its described like that all the time.

 

Thx for agreeing cmon when u spend more on ur speakers then you did for the car. YOUR CRAZZZZZZZY.

 

not everyone wants/needs a nice car but some people do like listening to their music being accurately reproduced.

 

If what your describing/meaning are bandpass boxes...then yes you are on the right track. They are a cheapish way to produce bass from speakers that otherwise wouldn't produce as much in a sealed box.

 

Bass is not non-directional, it is less directional. I've built competition cars for many years. It is very noticable to listen to a car with mono bass vs a car with stereo bass. Not much (bass) is recorded in stereo and this is the biggest excuse for using mono bass and just saying that it is non-directional. There are ways to trick the ear but it definitely can be pinpointed if done incorrectly.

 

so guys...what is the best thing to do wit ur system in a rx8??b/c i have 2 JL's..12'!and i dont noe hwo to put it em...whats the best thing i can do?any suggestions?

 

the funny thing I find is...people putting 12" sub's in the 8...i, like RotaryGod and several others, owned a stereo shop years back and I can make a box that sounds better and hit's harder with 8's than 12's, actually I bet I could do it with just one 8..never tried that...the best system I ever did on a non-competition level was for a Neurosurgeon in Birmingham in his Mercedes..had one 10" for bass and Focal components everywhere else...It had 5.1 surround sound with a true center channel and put several high end home theaters to shame...so it's all in a matter of DESIGN my friends...i'm not one into ground shaking bass either but I don't find it a waste of money to invest in a good system...but to each his own...you spend $700+ on a CF wing I can make a ground pounder for less than half of that...

if you know what you're doing which there are several members here that are very intellectual when it comes to audio, you don't need to spend $5000+ on a stereo to faithfully reproduce ear pleasing sound quality...

 

That was my point exactly......many people don't put much thought into what they put into their car. Just because a system sounded tight in a Eclipse doesn't mean it's gonna sound the same in the 8. You hit it....Design

 

i know..but see i had these 12's in my other car..and i just wnated to save money..so do u think to 12's wont go well in the rx8?

 

my point was that heavy bass does not make a great system. It is true however that most bass is recorded mono, there is not much reason to do otherwise.

 

If you want my honest opinion...i would sell them and not go any higher than 10's..12's are just to ....BIG...in every way..for the 8..that is

 

I'm with Xero......eat the 12's and go with 10's. Like I said just cause you systme sounded good in your other car doesn't meant it's gonna be tight in the 8.

 

Wow....look at my grammar and spelling. You'd never guess I'm college edjumacated.....

 

My system sounds very tight No boomieness.

 

Those look like sealed boxes which in my opinion would be the way to go if you deaden the trunk enough.
