XXX15 not loud enough. Help!

15XXX will not sound good with heavy metal. My 15'' RE HC sucked *** with heavy metal. I switched to 4 RE8s, and holy ****ing shit did it make a difference. I suggest you take advantage of the current off and sell the XXX and get a few RE8s. You will be very happy you did that. Trust me. I listen to heavy metal exclusively, and the RE8s have no competition.
You can also keep the XXX, get a 300x2 amp and power up some RE8s for midbass too.

why not tens? They sound sweet with metal and will hit harder and lower if he decides to listen to some Ludacris or Too Short. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

What was your box tuning and specs...I'm just curious at that. I know it can't be a problem unique to 15" drivers - there are some excellent 15" subs that handle very complex passages, but perhaps the design of the XXX wasn't doing the job in your case.

and power up some RE8s for midbass too.

I wouldn't, as RE8's are dedicated subwoofers, not midbass drivers. Koda 8's would be better suited for the task.

You're right Jack. I didn't take into account that my 15'' was in a big ported box @ 29hz haha. Either way, I sealed it in 2 cuft and the 8s took it anyday still.
