Does the type of music determine the size of the speakers to use?

 

IMO, No.

How loud and deep you want your bass does.

 

I am starting to care more about sound quality then how loud it is. I just want my music to sound like it should. I do listen to a lot of rock and metal. The only subs i have ever bought were 12's. I don't have that much experence with 10's, 15's, etc. I just want to know if the speakers I have are the right choice. My speakers have seen their better days. My subs are 7 years old.

Here is my set-up:
Alpine CDA-7897 head unit
Alpine MRV-T320 (80 watts RMS per channal at 4 ohms) running a pair of 5.25 Type-R componite
Alpine MRP-F200 (100 watts RMS per channal bridged at 4 ohms) running a pair of 6.5 Type-S coaxal
2 Alpine MRD-M500 (500 watts RMS each at 2 ohms) running 2 12inch Alpine Type-R Subs

I was thinking about replacing my head unit with a Alpine CDA-9886 and then replacing the speakers later.

 

wrong. woofer size does not effect how deep your bass is. frequency response is a variable of the voice coil's inductance and the enclosure.

to the op, the alpine 9886 is a good choice for sq installs.
check out Rainbow for component speakers. As far as subs go, you'll probably want to run a sealed enclosure because they usually yield better sq results. check out Image Dynamics for some nice sq subs. Its going to be tough to fit a 15 in the hatch of a camaro with proper airspace.

 

So you're saying woofer size shouldn't be a determining factor no matter how loud or quiet, high or deep the the bass is you prefer to listen to is?
So somewhere out there, there's a 6" sub that's perfect for all my loud/deep bass requirements. I'm sorry but I don't think so. Yeah, in the right enclosure that 6" sub will play some really deep low bass, but as soon as you decide that you want it loud also you're going to be really disappointed, probably about the same time the sub blows apart!

 

nope. thats not what im saying. please show me where I said woofer size had nothing to do with loudness. more cone area equals more volume. the deepness however is not affected by the cone area. That is a variable of voicecoil and woofer design.

 

Loudness wasn't in question, music type was.

A larger speaker may overcome roadnoise and stuff like that easier though, as (I believe) sound increases 4 fold when distance is halfed.

 

bluez28 stated that deepness of the bass was effected by the speaker size which is incorrect. thats what we were talking about.

 

Let me correct my initial answer to his question:

Question:
Does the type of music determine the size of the speakers to use?

Answer:
IMO No, but how loud and deep you want your bass does play a factor in choosing speaker size.


Speaker size does play a factor in deep bass, since deeper/lower bass requires more xmax, and a smaller speaker requires more xmax compared to a larger speaker to reproduce the same bass frequency with all else being equal.

I reread my posts and see your point RKPsk8er.
My Bad!
Thanks for the correction, RKPsk8er!

 

In my 20 years of audio experience the enclosure is more important than actual speaker size when trying to produce lower bass. Enclosure first speaker second. Regardless if talking about subs or midbass. If your enclosure is wrong then it won't make much difference in how large the cone area is. Also technology has change alot of things. Some 8's and 10's can have far lower octave bass than 12's and 15's. Think in engine terms, a small block stroker can beat the hell out of a unmodded big block. Same with woofers. Some woofer have huge excursion and powerhandling these days.
