Just forget they are 8 Ohms, put 100W or more of RMS power (not peak) at 4 Ohms to each one and you'll be impressed.
We have just posted our new BYOS (bring your own speakers) brakets at http://www.monstertower.com/accessory2brackets.html
and would love some feedback. Basically its your speakers, our brackets, ready to install with instructions for the Kicker KB600, ElectroVoice Evid 6.2, Bose 151' and a universal DIY bracket. Sorry about the plug but were still tweaking it and would love some feedback before we start promoting it.
