Posted March 1, 200718 yr The site says 1cuft per sub ...so should I go 2cuft net for both...or a lil more? lets say 2.2 cuft for bothAnd also...I am thinking of getting a Lanzar Opti2000d. Is that a good choice for these subs?the opti will give them 350wrms (which they are rated at) @ 4ohmThanksmy first post here

However, if you're like me and want quality over quantity, I'd go with 2.2 or even larger to increase capability down low.

March 1, 200718 yr I'm fairly certain you could hit 120 dB with 700 watts to two 12" drivers. One of my friends has a single 12" Audiobahn and he can max out my RadioShack SPL meter at 126.Actually, I don't even have a car to put a sound system in; I'm only doing a home audio setup in my bedroom (when my parents lets me buy stuff), so I can't give any recommendations for car amps (Behringer EP2500 anybody ). Sorry. Edited March 1, 200718 yr by DIYiT
March 1, 200718 yr Can't say that I am a Lanzar fan, but wtf it will probably do most of what you ask.
March 1, 200718 yr Author Can't say that I am a Lanzar fan, but wtf it will probably do most of what you ask.I think im going the kicker route...im thinking about zx1500.1 ...that will give the subs around 740watts @ 4 ohm and plenty of power for upgrading in the futureM5..what do u think about the sealed box size? 2.3 good enough?
March 1, 200718 yr Hi Bigrock,A 1 cube box gives a Qtc of ~0.54 and a decent F3 for the box size. Going larger will decrease Qtc and result in a higher F3. You may not notice the difference, but you can always experiment with adding fibreglass or polyfill. This can increase box "volume" by up to 30%.Add 0.2 cubes for driver volume (each). Best,Mark
March 1, 200718 yr 2.3 shouldn't be too far off, as Mark stated you can get a little more perceived space by stuffing the box.

Best,MarkHow are you comming up with a Qtc of ~0.54 in 1 cu ft? When I enter the data into WinISD, I get a Qtc of ~0.758. Is this a discrepency with WinISD calculations?
March 1, 200718 yr My post is based on one driver only - this could be where the discrepancy is. Perhaps I should have mentioned that - sorry.
