Those with XBL^2 experience

I've been planning on getting a new Stereo Integrity Mag when they arrive in a few weeks so that I can downgrade the size of the box in my cargo area. Going to go from a 4 cube ported box for a 15" down to 1 cube sealed for a 12. I thought the new Mag looked interesting and the XBL^2 sounded cool.

But after reading some more things on XBL^2, the consensus seems to be that it's a more laid back sound. But they also say that the sub blends seamlessly with the front stage. I like a more aggressive woofer that smacks you with hard transients that kinda snap at your chest. I also like a sub that can play the lows with authority. I listen to maybe 40% rap, 25% pop/r&b stuff, some techno, and 80's rock.

Would I be making a mistake getting the Mag? It has a pretty low Le (.8), which I figure would help with transients, and seems to have decent motor force. So I don't know how the laid back sound comes in? If this wouldn't be a good sub, could you recommend something else that will work in about 1 cube sealed and be $300 or less?

Nick... the 2nd gen Brahma 12 in a .8cuft sealed box with 400watts was by far the best sounding sub I've heard in a car.

Ever since i've been a huge fan of XBL^2... thus why I now use mids & mid bass drivers that use it.

Don't be afraid... and remember.... so much of what you want, can be achieve through box design & eq tricks.

One thing about the brahma I had.... it didn't seem as loud as other subs... I mean it was loud... but it seemed to blend and be disguised better which I fully believe was due to the lower distortion compared to other subs..... "laid back" just might mean "I didn't notice it as much".

that's good to hear. I was hoping you'd see this since I knew you had a Brahma. Thanks

I don't have golden ears or anything, but I really love my Brahmas. I had 2 15" Mk I's. I wish I had never sold them to pay the rent. I told myself if I found a used one I'd buy it in a heartbeat, and I stumbled across a 'broken' 12" MkI online for $40. Supposedly it had a burnt coil, but both coils measure 1.6 ohms, so I'm putting some nice quality terminals on it, and calling it a day!

Nice find!

There's a decent chance I won't get one ordered and installed until Thanksgiving, when I can go back to my parents' and use my grandma's woodshop. It's quite a drive to just build a box and things, so I may have to wait for another reason to go home (plus some extra free time off work without having to take vacation days).

If I build it right I think you guys will like the install after i get it finished. The box will be L shaped to fit around the wheel well and the amp rack will go over the wheel well. I'm trying to save lots of space here, as you can tell. I'll be sure and post pictures.

if you can scrounge up the money... why not do fiberglass around the wheel well, and the rest wood?

hmm. Fiberglass is not something I've tried before. It would be an experience. I'll have to think about it I guess.

I'm a little late to chime in but I have nothing but praises about all the XBL2 drivers I have heard before.

My Brahma is the single best sounding sub woofer I have heard installed in a vehicle. Very present low end and it had very good output even when it was running around 400 watts in a ported box. The low end extension is absolutely phenominal to say the least.

I've heard nothing but good things about the new mags too. I'd say go for it and don't think twice!

I'm just happy that XBL^2 is still being used in current production runs. When Adire went down I thought I'd have to go with crazy expensive underhung design, or that other one... the wierd winding one... can't remember it... Sound Splinter uses it tho.... and I think the new RE XXX uses it... split coil? ehh... can't think of it.

regardless.... XBL^2 is my favorite way for subs to get a flat response. A lil disappointed the mag only does xmax in the teens... but oh well, its $250, will still be plenty of bass for daily driving.

Nick... I suggest you do the glass, its fun once you get the hand of it. Plus, you'll be able to save a little bit of space, a little weight, and if you do it right... the box will fit snugly in place and will be less likely to shift around.

The other option is the SubDuction line from CSS...they've got XBL2 and Xmax in high 20's to 30 mm.
