Cerwyn Vega 215 get some KTM/redbull stickers to plaster all over them and call it a job well done!
I know Klipsh might handle the power.  However, you better like the high frequencies  I would imagine they might have to large in size.  A pair of REL S2 SHO's would be able to handle the low end because they are amplified.

I will be curious to find out what this group comes up with.  However, I think you should find out if they are dealers because they will want to sell you something.  I would not purchase any speaker without auditioning them that's for sure.  

You also did not mention room size and price range.  I am sure the knowledge in this group can be a big help.
actually, my son doe's have a pair of klipsh speakers. i don't know what model it is. only reason he want's to bridge is because he has no funds to buy an amplifier to suit his needs. he want's to bridge to see how much louder his klipsh speakers will go. when i went to see led zeppilin at the forum in l.a. ca. back in the 70's, it was loud! i think he want's to hear his music that loud!!!
Tekton.  Eric makes his speakers to capture the dynamics of a live performance.  Theres a video on you tube where he explains how he’d listen to live performances and then try to build his speakers to reproduce that style of dynamics.  Most, if not all of his speakers use large paper drivers that look like pro audio drivers for the midbass and bass frequencies.
