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!

Rated 5 out of 5 by from Replacements speakers gone rightBought these to replace 6units of speakers I had from a well known speaker mfg that I'm currently using which cost a massive 3-4x more than this eminence model, plus a very very bad customer support that I got from them made me decide to purchase & replace the originals in the cabs I had with these guys & oh boy! Was I happy with it after I burn them in with a QSC PL series amp running in parallel(Actually, I like them even before they were burn in...haha) . I don't own the speakers I had, I work for a company that own them & the words that came out from the boss mouth was, last year the speakers didn't throw that far(Nope, he didn't knew I replaced the originals with the eminence lo freq driver...wink!) This was not the actual model from eminence I wanted but hey, they work good so I'm hapi :D

Asked by: lltdj
This should work well as a replacement. Please double check frame and cutout dimensions before committing to a purchase.

Do new out-of-the-box pro audio woofers such as the Eminence Delta 15LFA need a break in period with a test tone or anything like that?

Asked by: mdunni01
All drivers will require a break in period. This period will be different with every speaker but usually after 15-30 hours of play time it will be pretty well settled.
