Best $500 speakers for Home theater only?

I am thinking about splitting up my combined ht/2 ch system. What would be a cheap pair to use in the ht only rig? I will be using them without a center channel. I have a Velodyn dd15 sub to supplement. Amp is 150wpc b&k.

...scroll down to the speaker section on Emotiva's page and look at the ERM-6.3's shown in the picture. Emotiva is their own manufacture, and direct distributor to the end customer, which is how you can save. These are $499 each, and will likely offer far more for you money in a dynamic HT speaker than you can otherwise get.
I think you're looking at something like dual 6.5" woofers, dual 4 1/4" midranges and a 1" tweeter. If they sound anything like their small reviewed pairs, you should be doing very well here!
Having dual woofers and midranges should offer superior dynamics, better power handling, better distortion cancelation, and a more solid overall image and dynamic from your transducer, all things equal.
Just a thought...
It's for ht! How good do the speakers have to be?? They will be crossed over at 80hz.
I am planning on getting their new processor, so maybe that would be a good match. Thanks for the replies!
Only problem with bookshelf is you have to get stands that would prolly cost as much as the speakers!
