Let us hypothetically consider GT5 (15vs12) to illustrate the same. Basically my friend wants to know - "If size matters"
baba I think we went through all this before..

it all depends on the design on the sub, it's cabinet (if any) and it's interaction with the "room".

for example the GT5 15" sub might be perfect for a Skoda Octavia but might be overkill for an Alto where a pair of 8" subs might be more suitable.

When you compare the GT5 15 to the GT5 12 remember that while the 15 has a lower Fs it also will have higher Mms and a lower BL/Mms ratio (now I say this without even looking at the specs of either woofer so it can be all wrong, what I state is merely an "educated assumption").

If one was painting with a broad brush once could say that the 15" sub would demand an amp that can "swing more volts", a bigger box, a bigger cabin and will be prefered to a XOed a bit lower than it's 12" equivalent. It will however produce more SPL and go lower than the 12" sub.

Would a 15" be lower in sound quality compared to a similar 12"? I am looking for sound quality, and still not sure whether to go in for the 15". I have a Scorpio, and thought maybe a 15" would better fill the insides. Can the 15" sound crisp, or are they more muddy? Already on a JBL sealed enclosure 12", but could go in for a good sealed 15". Any suggestions, and the cost?
Thx.

Offhand, what size subs do you recommend for a Zen Estilo? (In terms of room space etc. think of it being very similar to the WagonR). - and oh yeah, SQ is way way more important than SPL, and since this would be fed off two channels of a 4 channel amp, the power that can be supplied to it would be limited.

I have not heard either the GT5 12" or 15" but yes a 15" woofer can sound as tight/crisp as a 12" provided the box, cabin etc. suit it.

I would choose between a 10" or a 12". It is more than adequate. The reason 12" woofers got so popular was that they fit a wide variety of applications. With a 12" cone you could get low Fs, high SPL, etc... with smaller cones one had to depend more on Xmax. With bigger cones box volume would be a hinderance. Now this is just a general statement based on the technology of the 60s and 70s. Today with FEA, FFT, etc... things have changed a bit.

Car in question would be the Santro. So cabin isnt really big but boot can be sacrificed for this. He's got Hertz comps up front running off a 75.4 and the sub being installed is a 15" Hertz. Rear Fill unknown.

Knock Knock....
How come the most popular thread is sleeping for three days???
Where is everyone??

Ok, I'll put up my question to the Gurus.
Is there any ready made kick panel available which can accomodate a 6.5" woofer (HSK/ESK163) for Alto?

HI guys,
I need your advise here. I am pretty dumb when it comes to car audio. please help me out. I have an accent , and the company guy gave me a nippon cd player as a compliment, it promises 50x4 RMS and i think the speakers are nippon itself i can't see them,. i seriously want to change it. but to begin with i wanna start with the speakers and then maybe at a later stage change the headset too, please suggest wht kind of speakers i should go for and , my budget for the speakers is 6 k.
should i get the head unit too changed? if so wht decent played would i get for 6-7k.?

You can get a good pair of components at 6k - JBL GTO, Hertz Deici, Illusion Electra, etc.

Your HU budget can fetch you a Pioneer 6950 or a model older in Pio.

However, you can retain your HU if it has a pre-out and spend the money on an amplifier or better speakers.
