There's alot of solutions at your price range.
Don't take this the wrong way, but I think you overbought in terms of receiver price. Generally, I like to use as a rule of thumb that my speakers cost about double my receiver. Why? Because speakers last and have higher resale value than electronics, which go obsolete faster due to changing formats and standards. My guess is you bought it because of its HDMI upconversion, which may or may not be future proof.
With that off my chest, I'm a huge advocate of internet direct speaker companies. Axiom, HTD, AV123/Onix, Aperion, Ascend and alot of smaller boutiques. My two favorite are probably AV123 and Ascend. Go to both websites. However, you may like a brighter sound then Axiom would probably be the better bet.
In the case of AV123, check our their X line which has tons of value and probably has the best cabinets this side of audio. In the case of Ascend, its a little simpler, you should be able to slap something together using their CBM-340 which is an excellent speaker. Both use parts way more expensive and better designed than your mass market Worst Buy etc speaker.
