I Hooked up my brand new polk rti12's to a 140 wpc denon 7.1 receiver and I was instantly convinced of their quality. partricualry with the cryatal clear mids that I usualy tune down ( I'm a downward V shape kinda guy with an equalizer). I listned to a variety of music, journey, ac/dc, zz top, the cars, stevie ray, etc. and again and agian I was most impressed with the over all performance.

Well, these speakers have three 7 inch drivers on the low end ,and two 5.25 mids plus a silk dome tweet on the high end, and are bi-ampable with a power handling of 500 watts. I just had to bi-amp!!!

I had a hard time getting the right sound. i tried various combo's and ended up with a quite complicated set-up to get it right. its all great and I am still tweeking it but here is how it goes.

I have all my music on a computer in windows media lossless, streamed to an Xbox 360 running windows media CENTER ( hard wired). ( this is viewable on-screen on a plasma tv.) the path it take is computer to xbox...to graphic EQ, wich I have tuned all the hissing and screaming highs down, and that runs into a Denon 140 wpc 7.1 receiver. this reciever runs the two 5.25 mids and the tweet. By its self its actually sound pretty good especially with a polk 12 inch sub. on the denon 7.1 its has pre-outs and i run that into yet another EQ wich is focused on the lows and that goes into a 120wpc denon dual mono amp which powers the three 7 inch drivers.

this is the only way I could get those three 7's to start moving and pushing some air. I would like to get rid of BOTH EQ's because i don't want the coruption of signal...but hey, it sounds really good!


I think my problem (solution) is that I don't have a seperate pre-amp to drive the denon 120 wpc dual mono amp.

I can hear that I have saccrificed some of the crytal clear mids and highs in exchange for some chest pounding lows. and to most people my system would sound very impressive. but i want those mids and highs back...AND the lows!!!

any suggestions?

P.S. Don't get me wrong. These are AWESOME speakers!

Wow! Nice. I sold a DBX-140 (IIRC) unit some time back that may have helped but not ahving done anything near what you have I may be wrong. Can you do anything with vinyl?

havn't had vinal in years. curios how it would sound with this system though. perhaps I need to seperate my music from the home theater and get dedicated. this sytem is way more than one needs for ht anyway. unless you have a 2000sqft room!

I may be going out on a limb here (not the first time) but IMHO vinyl may address some of your issues. I don't have the computer set up as you but I notice a difference when I play cds vs. vinyl. Though clear as a bell the music from a cd seems to be just "there" in the sense that there is a difference between having a thrown to you instead of thrown or being yelled at instead of spoken to. The message comes across plain as day but the sound is sharp and lacking in subtleties and nuances of conversation. Maybe more akin to text messaging vs. writing a letter (anyone do that anymore?). If this makes any sense, carry on. I have yet to -*test*-('") the identical album on vinyl vs. cd vs. tape. Paul Simon's "Graceland" being the only one I have in all three.
