Ensemble System - Sub Overkill???

[ismarketing]

Thinking about investing in the Ensemble system. I have a very nice Genesis sub that sounds great, but using it with the Ensemble for an extra 5hz of extension seems like overkill.

For those that have heard the system, can the -3db @ 25hz spec be believed? I'm not a "thump thump" bass nut, but I love how full extension opens up the soundstage of a system.

Thanks in advance for sharing your experience.
