What 2.5" VC subs for Street Stock B ??

Well, since the plan for me and my bro's mini team originally consisted of bassrace competing only, after some though, we figured if we can swing it, we should at least finish the van build to suit a DBdrag class too. for a little more to do at the shows..

After alot of reading on termpro, we've found (to the best of my ability)that the only thing keeping us out of Street stock B (where us noobs belong anyhow..lol) is our 3" voicecoil subs.
Since the 3" voicecoil subs and the bigger amp we'll be getting will eventually be going into my car build(when it starts) we figure for the 2k in the van now, 2.5" coils should be fine, and put us in a dbdrag class more suited to us than street C and the SUPER LOUD cars in that class!!!

Soooo. if you were gonna choose 3 - 2.5 " voicecoil subs to run in dbdrag, bassrace and street driving, on <2k using a 7 cube PSP ported box box tuned to 44hz , what would you use?

I wasn't sure what you meant at first?? Its under 24" high, fits behind the 3rd row(even seats up) , thought it was a rules thing...
Then I checked the recommended ported box size for some 2.5" voice coil subs.

all less than 2 cubes per sub gotcha

Type R's
AQ SDC

I was looking up Kicker L5's , they have the same power handling as the 2.5" VC subs I looked at ( Type R, AQ SDC) but the recommended ported box size is the in the "right" size BUT... I can't seem to find anything on it's voice coil diameter, even in the PDF manual!!
Anyone here know?

Did notice that Digital Designs have some beefy looking 2.5" VC subs.
Haven't really looked them up too much yet... ie... look expensive....lol

We also need dual 2 ohm coils for our for our planned setup, I mention this because the AQ SDC only seems to come in 4 ohm...

So unless I want to scrap(lol yeah right!!!) the new box I need to find a 2.5 inch dia. dual 2 ohm voice coil sub, that has a recommended ported box size of no smaller than 2.25 cubes...

Only found one even close yet, gotta find out about the L5's voice coil!!!!

Any new thoughts guys?

There is no limit on voice coil size for street stock. Just no competition grade subs. American bass xfl subs are a great sub and legal fir street stock. The price is pretty good for what you get.

"competition grade" - wtf does that even mean? seriously.
it wasn't that many years ago that people set SPL records with L7s in the street classes, how are they no longer considered "competition grade"?
