I'm currently running one 12' sub, sealed, in the spare tire well. I'd like to add one 10' sub under the strut. I understand that adding another 12 would asthetically look better, but I do not wish to redesign my current enclosure or design a new one to accomodate two 12's. What I'd like to do is add an "under the strut" enclosure with one 10'. Of course it would be the same brand as well as power handling capability. Both subs would be Fosgate T1's.
1. Does anyone know how this will effect my sound quality?
2. Will there be a noticable difference in bass quality/output? If so, will it only effect certain freq ranges?

Thanks for the input.

 

theoretically the 10 should hit tighter and hit some higher tones than the 12....whether it does or if you can hear any difference is another story

 

that's what I was wondering. I concerned about any abnormalities in sound that might occur as a result of running 2 different sized subs. It's ok with me if it's not noticable to the ear though. I perfer them to hit in harmony rather than one have to drown the other out inorder to hear a good bass note.

 

use a different Xover point, so the 10 can handle the tight drums better. make the crossover for the 12 inch sub to ONLY handle the lowest range of bass, should be fine if you have it proffesionally tunned

 

as long as you go with the same speaker just size difference, the 10 will hit just as hard as the 12 but you will increase your bass freq range.

 

interesting theory, but I'm looking for both subs to hit simultaneously during common frequencies.

 

you can of course try it


IMO same sub size is better than mixing


your sealed right


i would consider buying a new T2 12" dual 2 and run at 1ohm ported not sealed


i think this would make deeper ,and louder bass, than your current 1 sealed t1 12 ,and 1 t1 10 sealed you wanted to add


re-design IMO

final result will be better


what amp are you using on lows

 

IMO 10's are more mid bass and do better at 45-60 hertz

IMO the 12's will sound way deeper and louder from 35-45 hertz

box tuning , music preferances play a part , also resonant frequency of the car as well

 

1. Correct, I am running a sealed enclosure.
2.I'm currently running the Dual 2ohm T1, but at a 4ohm load vs. 1 ohm. My Fosgate P8004(I believe) is incapable of stability @ 1 ohm. I can run 800watts bridged @ 4ohms or run 2 channels equally. The bench test on the amp rated it @ 941 watts RMS @ 4ohms, so I'm figuring I have a bit more to play with.
3. I aggree with you that a ported enclosure would accomodate my needs more, it's just that I'm not willing to give up the required air space to accomodate a large ported enclosure. With my current set up, I'd only be able to fit a 10' sub under the strut. With my new false floor, I'd only be able to fit an enclosure faceplate, capable of housing a 10' sub, under the strut.

 

Agreed, but I only plan on using sealed enclosures. I won't be able to tune the box as with a ported enclosure.

 

your punch p8004 is NOT 1 ohm stable , 2 ohm yes


i have a 2005 punch p8004 for sale , along with 2 each punch P6001bd for sale as well

all punch amps are 2 or 4 ohm stable


power series are 1 or 2 ohm stable

 

Shiat, I just noticed the specs on the amp!:

It's been a long time since I looked at the owner's manual. I'd have to buy a dual coil 4ohm 12' sub in order to drop the 2ohm load, to get any real power out the amp using 2 channels. I not sure if I want to pony up for a new sub either, I just replaced my old sub recently.

 

either that or I could buy the 10'sub in a dual 4ohm coil, then wire the 2 subs in series to drop the 4 ohm load.

 

please do not fire one sub up and one sub back with different sizes. You will be doing more harm then good. Being the fact that you have different airspace between the boxes with different sizes your subs will most likely be hitting at different times and the sound waves will be canceling each other out.

 

Honestly, Running two different drivers won't be Noticable for about 80% of the folks that just blast the bass.

If you have an ear for SQ and REALLY want the best sound, Either Stick with one Driver OR run the 12 for the lowest frequencies and the 10 for the higher freqencies and put a 24db slope between the two. THere will still be some issues on getting the subs to "dissapear".

The key to sub base is NEVER HEARING THEM. You should only Feel 90% of it and the other 10% should appear to come from the windshield.

 

AND I MIGHT ADD..

Unless you are going for some SPL numbers, I have never seen a system that required any more than 1, single 10" or 12" driver to have the perfect "SQ Perfect" Sub Bass.

(My Screen Name is SQ40, Guess what the SQ means..)

 

show quality?

anyone can say sq but that doesnt mean they know what they are talking about

 

My Little Friend here in my living room says I know a thing or two about SQ, What have you got? (That says WORLD Champion on there in case your eye sight is bad..)




Now, Instead of getting in a pissing match over who has what and who has a better ear, lets try to help the OP out a bit.

What do you say?

 

wasnt trying to **** in your wheaties Just giving you a hard time and I allready think we told the guy what he didnt want to hear so surely a little fun cant hurt

 

sq refers to sound quality
not show quality
