Eminence response curves are measured under the following controlled test conditions:

All speakers are tested at 1W/1m using a variety of test set-ups for the appropriate impedance

LMS using 0.25 in. supplied microphone (software calibrated) mounted 1m from wall/baffle

2ft. X 2 ft. baffle is built into the wall with the speaker mounted flush against a steel ring for minimum defraction

"great bang for the buck"
Overall: 4.5 out of 5 stars
I purchased the LF driver for a slotted 3cf port tuning it to app. 30 hz. and it pounds like a wrecking ball on old concrete. Very articulate base. The crossover is a Dayton that cuts off at 250 hz. and can withstand 600 watts of a.e.s. pink noise. I push this baby with an EPX 4000 bridged from Behringer that is connected to same brand sonic exiter and rack mount line mixer. This baby can take the the signal modifications I am sending to with little effort. Can't wait to use it on my first gig.
