thank you everyone for all the info!

Very few of the subs that I researched followed that pattern. Maybe they did adjust the suspension on the smaller drivers to keep the Fs low, I really don't know. All I know is that a larger cone size didn't give you a smaller Fs on nearly any of the subs that I looked at until you got down to the 10" or 8" versions.

15A - Fs: 28.80 Hz
12A - Fs: 27.3 Hz
10A - Fs: 28.63 Hz
8A - Fs: 33.38Hz

IDQ 15 D4 V.2 - Fs: 21.5Hz
IDQ 12 D4 V.2 - Fs: 19.7Hz
IDQ 10 D4 V.2 - Fs: 26.0Hz

IDQ 10 D2 V.2 - Fs: 23.0Hz
IDQ 12 D2 V.2 - Fs: 19.0Hz
IDQ 15 D2 V.2 - Fs: 20.5Hz

IDQ 15 DVC - Fs: 22Hz
IDQ 12 DVC - Fs: 19.5Hz
IDQ 10 DVC - Fs: 23Hz
IDQ 8 DVC - Fs: 26Hz

CMP 15 - Fs: 29.2Hz
CMP 12 - Fs: 28.6Hz
CMP 10 - Fs: 33.5Hz

Need I go on?
For several of them the 15 had a slightly lower Fs, but it was nothing substantial (1-2Hz), and I noticed no pattern until you got down to the 10" or 8" versions. I don't know, maybe it's just because these are some of the best subs out there and RF, Sony, Kenwood, etc don't take the time to tweek their designs so they sound the best. I guess we're both right, it just really depends on the specific sub he's looking at.

Fs is lower on the 12s but I am guessing it sounds cleaner on the 15s to hit lower

sr20de4evr · 11-23-2003, 03:04 PM

Well to hit the same SPL at those frequenices the 15 will be cleaner because it doesn't have to work as hard to hit them, simply because of the cone area. But if you had 2 12's vs a single 15 I don't think there would be any difference in the "cleanliness" of the sound.

sr20de4evr, how long have you been interested in car audio? you seem to know a lot about it.

Haibane · 11-28-2003, 10:21 PM

He's probably been in the buisness a lot longer than me. Gsteg and him are the man.

PaulD · 11-29-2003, 07:57 AM

for most companies - 12's & 15's share the same motor (magnet) .... there will be little differences except a bigger cone area.

I'm only 19, just a poor college student who works during the summer and then wastes all the money away on toys when I get back to school

I only seriously started looking into car audio about a year ago. I spend most of my days reading though, you wouldn't believe how fast and how much you can learn when you read several hours a day, every day of the week on boards filled with some of the most knowledgable people in the business. I spend most of my time (that should probably be spend doing homework, lol) over at www.soundillusions.net and www.caraudioforum.com

I think this one would be pretty loud.

I bet that is one crappy sounding sub though

sr20de4evr · 12-01-2003, 04:53 PM

hehe I've seen that before
supposedly they were using a Uhaul style truck as the enclosure and during a burp (8Hz or something) it collapsed the trailer. I think it hit something like 170dB at 8Hz though

Haibane · 12-01-2003, 05:18 PM

that sounds like good entertainment there...
