sent this to Polk customer service, thought I would post here to see if I could find any help at this forum:
I want to horizontal Bi-amp Polk rt 55i speakers. The manual says they can be bi-amped this way, however, the top posts only send signal to the tweeter, there is no mid range. The bottom posts send signal to both the 6 in drivers. I did not expect this. I would think the designers at Polk would have used the top post for high and mid and the bottom post for the low stuff using the bottom 6 in driver. Apparently they are not set up this way.
My objective is to use my tube amp for the high and mid range, and a solid state amp for the "punchy" low stuff. Obviously these speakers are designed the way they are for a certain reason, but I think there is no real "bi-amp" capability with the way these are right now even though the manual says they are. I do not think using a dedicated amp to just drive a tweeter is what Polk intended for bi-amping.
I would really appreciate any information or insight on this, I can respond with more specifics if you need more information than this.
thank you so much,
