Wasteland_Audio Posted January 21, 2017 Report Share Posted January 21, 2017 I think a lot of people forget just how much cone excursion matters in a situation like this. Think of the cone as a cylinder instead of a flat surface, diameter x xmax. Now instead of surface area you get volume, that is the amount of air the cone moves in a single stroke. Now double the power and you can move that air with that much more force. It's the same situation Gunnem described. However I also agree with ShadeTree, putting those 2 12s in a custom box on the 1200 watt amp will basically be doing the same thing but with efficiency and force instead of air movement. Plus you wouldn't need to drop $1200 or whatever on a new sub. Link to comment Share on other sites More sharing options...

RainStryke Posted January 21, 2017 Report Share Posted January 21, 2017 A few years back my local JL dealer let me listen to the subs in my car, so we took them out of the store and tossed them in my trunk to test them out. The W0 12's were excellent subs for the power they use. My personal opinion was the W7 13.5 in their custom red eye box sounded cleaner and louder than the pair of W0's in the powerwedge box and the W7. The big deal here is the power output is also going to be over double... so that's something to also consider in the comparison. If you have a JL dealer that is wanting your business, they might do the same for you. Link to comment Share on other sites More sharing options...

RainStryke Posted January 22, 2017 Report Share Posted January 22, 2017 I'd rather have a 13.5 W7 over a pair of SA-12's between those choices. Personally I'd also consider a Sundown Audio Xv2 15 paired with the Rockford Fosgate T1500 over the W7 and the slash. But what it really comes down to is what YOU want. If you like JL and want their flagship, I'd go for it. Link to comment Share on other sites More sharing options...
notorious97200 Posted January 22, 2017 Report Share Posted January 22, 2017 Take a look t the 15" DSS ethos sub. It sounds good, and can be loud in a 3cu ft box. A new box for your current subs may be the cheapest choice, but you want to save space... Small box and big output ? Hard to do, but possible. Good luck. black BMW X1 2.0 l 192 hp OEM head unit, Amplifiers : Audison AP 8.9 amp with integrated DSP and Ampere Audio 1200.

If it were my car then I'd build a box that suited my space and tuning needs, then go for more power. If you really want to run a single sub, look into 15's that can can take a little power, maybe a fully loaded FI Ssd on 2k with an aditional rear battery? For the money, JL subs never looked like a deal to me. Link to comment Share on other sites More sharing options...
DLHgn Posted January 23, 2017 Report Share Posted January 23, 2017 Like everyone else has suggested, I would recommend building a new box for the 12's. You'd be amazed at what the box can actually do. If you're still not satisfied, maybe try upgrading the amp. Still not then get a bigger sub that can handle the new amp.

Skullz Posted January 23, 2017 Report Share Posted January 23, 2017 I will reiterate what i said earlier, get a pair of 12w3's on the hd1200. Those subs have been around 20+ years for a reason, they sound really damn good and can do exactly what you want without breaking the bank like a w7 will. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
