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

Rated 5 out of 5 by from Great SpeakerI bought these to replaced the Beta15A's I had in some single 15" scoops. One of the Betas started crackling one day when I turned everything on. Turned out to be something wrong with the amp that must have hurt the speaker. These sound really good in the scoops. Will buy these for future projects

Eminence Delta-15LFA 15" Low Frequency Driver

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: MarkDunning
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.

Will this speaker work for a Gemini P1531 15 inch 8ohm? If Not What are my other options for new woofers. I'm willing to change the crossover and make it a passive sub cabinet.Recomendations for what crossover and 15inch woofer? My amp (800W 8ohm 2speaker

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