Reviews

Eminence Definimax 4015LF 15" Speaker Driver
Eminence Definimax 4015LF 15" Speaker Driver is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from WOWjust hooked up 2 of these, (9fc cab tuned to 38hz) tight bass and deep sound even at low volume. hooked up to an ep2500 bridged 4ohm load, colud not turn them up all the way they started shaking my stuff off the walls. For the little extra cost they are worth it, now I just need 2 more.

Eminence Definimax 4015LF 15" Speaker Driver

Currently using the Eminence Alpha 15 in my open baffle (with an inductor and a cap). A friend suggested either the Delta or the Definimax 15 as an upgrade. Is the Definimax upgrade worth the extra $ and should I use a sub amp to drive it?
