rti a7

Hi I recently purchased a pair of RTi A7. Now I am interested in separating the woofers out and am looking for suggestions as to what would be the best way of powering them. I have a 20 year old Denon avr-800 with NO pre-outs. I will be replacing this with a new Denon AVR-S700w. What type of amp (amps) should I be looking for to power the subwoofers in the pair of RTi A7's. Thanks jpk

    I don't fully understand what you are specifically asking but will answer to what I think and you can correct. You have a pair of RTi 7's and a new receiver that's rated at 80watts per channel when running 2 channels. I would purchase a power amp to run your Rti7's and use the Denon 700 to run the rest of the speakers. 150-200 watts is the range I would look at. Used market can be your friend but there are also lots of new choices out there as well.

    I ran the Rti7's with and without an amp and they are really great with both.

    What percentage of movies or music will you be doing?

    Do you currently have a sub woofer in your system?

    There are no subwoofers in those speakers.

    I believe are you are thinking about some sort of attempt at bi-amping using the AVR on top and a separate power amp to drive the bottom. Forget you ever thought about it.

    The Denon S700 doesn't have preouts either, so you can't add an amp with that receiver either.

    As others have alluded, you need an AVR* w/pre outs. Seems your current AVR* & the one you're considering do not - essential to connect external power amp(s).

    Many say most AVRs don't have "the juice" to drive 'A7s* well - 2 channel. Throw in a CC and surrounds on top of them*, things get very challenging.

    I've never heard my 'A7s w/anything but a decent separate amp - pleased w/the results, so I can't comment*. In fact I only know, from a listening stand point, ARE separates, including to my surrounds.

    When you decide on your AVR or pre/pro...
