1 sub vs. 2 subs

how much of an better, if any, would it be to have one good quality 12 like a pioneer premeer ts w2000 than two 12's that would cost about the same price together.  I know there are some deals for decent subs at that price.  ANy suggestions?

Thanks

It all depends upon many factors.  Box, amp, type of sub, ect.  You could go with something like a JL 12w7 (500 watts w/ excellent sq) in a sealed box or two JL 10w6 and pay bout $20 more but be getting 800 watts for both subs and then put those in a vented enclosure and come out with probably louder and just as nice sounding system.  But w/ the two tens you might want a stronger amp to recieve the sub's full performance.  That's just one example.  Like I said the possiblilities are endless.

sorry   /r 7 i didn't write that very clearly im not only looking at pioneer, just an example

any other suggestions with price are greatly appreciated

i always liked the sound of just one sub but thats just me

btw doesnt adding another sub only give u 3 more db anyways, so i figure whats the point

Straight away, one quality sub over two lesser ones.  While I totally agree that a cheap sub can sound its best in a very well constructed, well conceived (designed) enclosure;  the bass will always seem sub-par to a high quality subwoofer a proper enclosure.  I would rather have SQ over SPL any day and who could possibly say that 1 12 is not loud?  I cannot say enough that people who listen to my 1 10w3 system tell me its far preferable to their 2 cheap sub system.

Don’t be afraid to go with that high quality 12 and skip on those two cheap ass speakers.  Be ready to build a solid box and get the amplifier to power that bad-boy.  I can personally recommend the W3v2, w6 and w7 (al JL).  Never even heard an Adire, but the hold very high acclaim with those who have.  The HX2 Rockfords, Alpine Type S and Infinity Kappa Perfect are all good subwoofers.  Depends on if you want to sacrafice a little spl for sq, but all of those subs sound "good".

i'm pretty sure that you're right wiseguy when you say you only get 3 more db but to get 3 db is like addin atleast half as much power ontop of what you're already puttin in.  so yeah it's not a lot (of sound increasement) but when you look at it it takes a ton more power to add those 3 db.

i'll second heavilymedicate's notion of one quality sub over two lesser ones.  You could hook up ten rockford-fosgate punch z's and put that up against one quality speaker (heavilymed uses JL for the ie.) and I put my car on it that the JL will sound better as far as sql, and probably come close to even with spl. 

Like I said though, you can get those 2 10w6v2's or get a 12w7.  Both run around the same price and both have probably the closest to "best sound" for the price you'll pay.  Oh and the 10w6v2's can be put in one SMALL box.  So box size can be taken into comparison.   Also look at Infinity's Kappa Perfect VQ those can run in like .4 cu ft sealed boxes.

thanks a lot for everyone's help

ill deffinately look into one quality sub, good amp, and great box

and i deffinately that its worth it to sacrafice a little spl for sql

anyone know any good internet sites for really cheap or discounted audio stuff?
