Rated 5 out of 5 by from Awesome OB driver....I have tried these in an OB project, using a 24"×24" baffle, 3/4" MDF. Currently not completed, but so far it makes wonderful amounts of quick, tight, but spacious bass. You won't be disappointed.

Rated 5 out of 5 by from Fits Behringer Euromix B155DFits perfectly into Behringer Euromix B115D powered speakers. (replacing their wanna-be "800W" 15's... yeah, right.. the originals most likely maxed at 200W..).Anyways, brought back to life with gusto!

Rated 5 out of 5 by from an excellent speakerI think PE is the largest Eminence distributor in America.So they carry more speakers than anyone else.Their selection is the best.I always try to order the Eminence Delta LFA speakers because according to the description they offer a little lower bass response than other speakers.And they sure sound like it to me.I have ordered this speaker in the 12"LFA and they are awesome.The 15 is earth shaking!

Rated 5 out of 5 by from Worth the money!I have used these speakers for a few weeks now in my 3-way system at home, and they sound awesome! They seem to be good quality, and have taken everything my amp can throw at them. Since installing them, my only problem is that my speakers move themselves around and shake things off shelves! Definately worth the money!

Eminence Delta-15LFA 15" Low Frequency Driver

Will these speakers be suitable to use in a bass scoop bin?

Asked by: AUX1Dub
I would not recommend these for a scoop application. A good choice would be the Omega Pro below.http://www.parts-express.com/eminence-omega-pro-15a-15-cast-frame-driver--290-430

Hi, i ordered a pair of these speakers and they just arrived, the foam surrounding is kind of sticky, is this normal, is this effect the performance? thanks for answer.

Asked by: Vincent Nguyen
This is a coating they put on the surrounds to seal them and provide the compliance they are looking for. It is perfectly normal.

I have a pair of these for low freq. augmenting.  But, was wondering "how high can these be crossed over at ?...can they be crossed at 3khz ? Thanks

Asked by: bladesmith
The high response for these speakers is 3200 Hz. I generally like to leave about a 500hz gap between speakers but it could be crossed at 3khz yes.
