Do I need amp?

Gentlemen, I have recently bought a pair of rti a7, one csi4, one dsw 550 and a pair of rti a3. I have also bought a sr5014 marantz avr. Will this be enough to move the whole set? Do I need amp for the a7s?

    If you listen to music you will always need an Amp

    How big is your room? Is this mainly for music or movies? Your mains will sound better with an amp, no doubt, but depending on room size and crossover point you might be ok without one.

    But I agree with Trey that if music is important to you, you will notice a significant improvement with an amp...

  • Thanks a lot both of you. Which kind of amp should I add? And how should I connect the avr, the additional amp and the a7s?
  • Thanks a lot rooftop59!
  • Would it be possible to use the subwoofer to amplifie the floorstanding speakers? The dsw 550 has a 200 w amp. What do you think?ffiknd7jv5gs.png

    NO!!!

    The sub amp drives the sub, nothing else.

    That amp can pass the signal on to your amplifier, but it will not power any other speakers.

  • Ok but then, what are those connections for? I mean the "speaker in" & "speaker out" that you can see in the picture.

    Those are for speaker level connections as opposed to line level type connections.
  • Thank you very much Ken and Kex!

    Welcome to Club Polk.
    Do I need amp for the a7s?
    yup. Unless Marantz stacks up well in the power department, after you get what you have set up, connected, sounding OK, those ‘A7s would be much happier w/a separate amp.

    I agree w/...

    Do not get a pro amp, get an amp designed for home use. Parasound, B&K, rotel are good [used] options. If you want to buy new here’s about the best deal you’ll find: https://www.audioadvisor.com/mobile/prodinfo.asp?number=PAC2125V2. Outlaw* has a great 5 channel amp you might look at: https://outlawaudio.com/shop/index.php?id_product=27&rewrite=model-5000&controller=product
    Avoid emotiva, they’re too bright for the RTiA series.
    lots of good advice above. Also Outlaw sells good mono amps at a good price.

    You should find some* used eBay, etc

    A side note: the last couple of weeks I’ve been listening to a pair of outdoor speakers, Polk Atrium 55 powered by either a Rotel, Parasound, or Belles. Today I connected them to a Denon AVR 2802 only to realize it will “do” for my backyard system but I miss the above 😟

    Enjoy! Tony

    Psst: I have Parasounds & a Belles for sale either of which your ‘A7s would love

    That Marantz is a nice AVR. IMO, you do NOT need a separate amp.
