Polk RT1 A1 Not Driving Correctly From Denon Amp

I have 2 Denon Amps:
Denon AVR 1613
Denon AVR X1300

When I hooked up the RT1 A1 speakers to the Denon 1613 they seemed flat. So I am wondering if the amps are insufficient for these speakers. Also, does anybody know a way I could run these speakers off a separate amp while the Denon plays the surround sound.

    the 1613 should run them just fine, either would really. You don't need a separate amp. Your problem is most likely in the setup menu. Re-read your manual, see if all the adjustments are made correctly.

    Neither one of those receivers have pre-outs to add an amp. both are very low powered products. To run anything more than 2 speakers would DRASTICALLY reduce the power to every other channel. At 75wpc and 80wpc by the time you have 5 speakers playing you are down to about 25-30 wpc max if that.
    I can understand why the speakers sounded flat there is no power to be had with either let alone any current to push any power.
  • I am running these speakers while using Energy 5.1 speakers. Are the speakers meant to be run independently?

    Running just one set of speakers? Are you in 2 channel mode?
    What Room EQ, and tone or Equalizer settings, and so on.
    Is this with music??
    Do you use a sub or run speakers full range?
    Define flat please?

    What channels of AVR are you using?
    More details needed.
  • Center, Sub-Woofer, 2 rear, and 2 Front. I substituted the two Polk speakers for the 2 Front.
  • Was also wondering why these speakers have 2 sets of speaker wire inputs...Does it matter which set is used? Upper or Lower..

    If you switched front speakers, did you re-run your calibration program?

    Any time you make changes, even moving existing speakers, it’s highly recommended that you re-run your calibration program.

    You have to run the calibration program any time you change anything. Did you?

    Bi-wiring is the point of those. You should have a jumper or plate that connects the two together and you just plug your speaker wire into either input.

    Could it be that you may have only connected it to only one set without the jumper? That would cause it to sound "flat".

    Re-calibrate all the time, move a sofa = re-calibrate

    Yeah if you don't have a jumper in there it will sound flat. Either the brass plates OR speaker wire.

    Does this question mean you're missing the brass connectors like on the picture codycatalist posted above?
  • The brass connector came with the speaker; but not this connection wire.

    The brass connector will work by itself, so long as both of the binding post nuts are tight on each set of binding posts. The wire is a inexpensive upgrade.

    Removing the brass connector and adding a speaker wire jumper is the best lowest cost upgrade anyone can do.

    Let us know if that "corrects" the problem. If the brass jumpers were already in place, I doubt the improvement from replacing them with wire jumpers will take those speakers from flat to full of life, but maybe I'm wrong...

    Did you re-run the calibration?
  • Interested to know if you have had any joy with your sound?

    FWIW I always find it better to have to main cables running to the tweeters rather than woofers.
    Maybe the jumper cables are too thick to carry to the tweeters. Make sense to swap them around to me
