hmm from the review I read about heir center, the shielding was inadequate, and nnede to be 5 inches from teh TV to not distort it.
That alone is a sign to beware, they prolly went the cheap route and bought regular woofer and just attached bucking magnets to them. The right way to go is to use an actual cup-type shielded woofer, since the emitted magnietic field is far smaller.
Plus the cabinets for some of their speakers strongly resemble the cabinets used in some of the KLH speakers...which scares me, since while the modern KLH uses halfway decent drivers in some of their speakers, their craptacular enclosures have always messed it up. I had a pair of KLH floorstanders and had to brace the living bejeebus out of them to even be able to play them even remotely hard....the woofers were powerful enough and the cabinets werent even braced, so on the first hard and loud bass hit, the front panel comes loose.
That is what I'm afraid of here....if those are KLH cabinets, you can be sure that the bracing will be very little if any...
IMO for cheap HT, Yamaha BP-4500. $250 at best buy for a 6.1 setup.
