Notes
*1 Power compression is the reduction of sensitivity at the specified power. Higher power ratings do not necessarily give a proportionate increase in SPL therefore the maximum SPL of the driver may significantly exceed that of other manufacturers with high power ratings.

Stefan Peterson –
Use these in an open baffle set up with 2 per channel. With some serious equalizing and Class-D amplifiers, punchy and powerful bass down to about 30 Hz is realized. To be able to hear and actually feel the dynamics in the low bass is an incredibly involving experience. Could hardly be happier.
