2 9515's box help - dodge magnum

[Full Tilt 10+ year member]

There is a local guy here with a single 18" DC Audio level 4 and about 3k doing a 153...........In a Magnum.......of course his box is tuned at 45hz.............I would do the two 12s if your plans are to listen to music decently......

2 12s, done correctly, could beat 153.

Not unless those 12's are in a bandpass lol...my single obsidian 12 spanks my 18 in terms of output when it comes to

Band pass isn't louder, if you put you 18 in 6 cubes tuned to 25 with 150in^2 of port area you will get similar results..

I've done a lot of installs and I've yet to use a bp over a properly built ported box.

if you want more output I can help with a transmission line //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I've done 145-146 legal @25hz with 2 he 10s and a Lanzar 1000d..

I assure you the single 18 will out displace the dual 12s..

It's all about efficency and displacement, the 18 will be louder with less power..

Well that makes it a proven fact that 12's play lower than 18's

Alan Dante did a 183.4 with 12 12" Z series on 210,000 watts in a 6th order bandpass //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

He did do like a 180.2 or 181.2 with a single DD Z 18 iirc.

Have fun with that nearly 100" long port that displaces roughly 9.5ft^3.

Yea, lol but wave length well be close to perfect and qt for port will be threw the roof, I'd bet u could pull low 150s..
