View Full Version : should i go for a 10" or 15" for SQ.

I am trying to build a low budget system that is total SQ. The speakers i am going to get are teh IDQ's. If i supply the recommended power to each speaker in a sealed box can the 15 sound just as good as the 10. It will be in the extended cab of my mazda truck. I want tight clean bass which i know the idq's put out but would getting a 15" be pushing the limits of a SQ sub?thanks

I dont know that much about IDQ subs, but overall i would say that 10" subs have better SQ than 15" subs. 15"s tend to be a little sloppy.

Why don't you just get 12's. Otherwise for total sq get the 10's.

The only difference between a fifteen and a ten is five inches. Fifteens can and do sound as good as any other speaker. If you heard a sloppy fifteen it wasn't the woofer's fault. Enclosure size,power,etc. was the problem not the fifteen.

pressurized....your saying that the 15 will have just as good sound quality as the 10 if properly powered and installed? so i wouldn't notice a differance in SQ between the 10 and 15? the 15 can play just as tight as the 10? I don't want 12's because i would rather have a 10 or 15. I guess i'm just tired of 12's. i want something new.

You will notice no difference in sound quality if the fifteen is set up properly. Except the ability to produce louder lower bass. I listen to much rock(creed, days of the new,etc.) and will not use any other woofer but a fifteen. It is only a common misconception that these woofers are sloppy. The only drawback is its size.

pressurized, what kind of 15's do you have and what kind of system are you running...sq or spl? thanks for the help. Now would a sealed 15 have better sq than a ported 15? i am guessing so.

I enjoy both SQ and SPL. I have two Kicker Solobaric fifteens in a three foot sealed box. For power I run two Mmats d-300 hc's. The box is sealed which usually yields better sound quality.

the reason 15s tend to be sloppier and 10s are tighter is because when a speaker company releases a certain line of speakers they use the same motor assembly for all sizes. so if you have a kicker xpl 10 it will hit harder and faster then a kicker xpl 15 only because the motor has to move that little 10" cone as opposed to moving a 15" cone. so if a company designs a 15 and they want it to sound good they put a huge motor assembly on it. actually thats not realy making it sound good, just making it tighter and faster.

well the idq 10, 12, and 15 all have differant sized motor stuctures so i guess the 15 can sound as tight and hit as fast as the 10. anyone have 15" IDQ's? if so how do they sound?

I would go with the IDQ 15" subs, or look on car stereo review .com web site, I think they have tested it. Against a Orion NT and a RF power DVC, It won for overall clrity and extension of the low bass.

In the Nov. issue of CSR they put 15's
of the Orion XTR 15D,Fosgate's RFP-1215,
and Image's ID154 againest each-other.The
ID's came out on top by a very slim margin.
Mind you this is not the version 2 model
which has had alot of good reviews and
write-ups.Also consider your space.As far
as SQ and on a budget you can't go wrong
the IDQ's.Best of luck

I run an sq system and use a 15" Crystal CMP. It is incredibly musical, no slop. And this sub can hang with just about any spl machine to boot. I put mine in a 3 cubic foot sealed box which is the largest recommended size and power it with a bridged MTX 2300.

Dont worry the peopel who say 15" subs sound sloppy obviously dont know anything about car audio!!! If I were you I would go with the 15", Go with the reccommended box size though!

just to let you guys know i went with 12's because they cost 250 for 2 while the 15's would have run me 500. but i already sold the 12's so i don't have any more tight SQ bass. but thanks for replying to my post, you must be checking the arcives huh, i asked that amost a year ago i think.
