Best Sub for A9’s

Just got my A9’s and believe a sub would help round the bottom end out a little better. Mostly listening to music, variety (rock, jazz. rap, country), want solid full bass, but not overpowering, distorting the rest of the sound. Would like to keep it under $500-600.

    Before you spend money on something you don't really need, what are you driving the A9's with?

    With the proper amplification you will not need a sub with those speakers.

    I'll second that suggestion. Unless you really want a subwoofer for HT duty, then the SVS's mentioned would do well.

    I would first power the speakers correctly and then make that decision though. The fact that you said you wanted to "round out the bottom end" tells me your underpowering those big boys.

    As for amps, look for used ones in the 200 watt per channel range from the likes of Parasound or B&k. Expect to pay anywhere from 400-600.

    Yes, you have preouts than enable you to add an amplifier.

    ^^^what she said^^^

    That SVS 12NSD is a nice sub, I wish I would have had the funds for two of them when they were clearing out.

    You might also want to look at HSU http://hsuresearch.com/subwoofers.html I like that they can go from sealed to ported with ease.

    There's your real problem. You'll never get what the A9's can do until you drive them with a man's amp. A sub isn't going to help.

    Recommendations? Do I need to add an additional amp, if so how much?

    What is your precise Onkyo receiver, we first have to make sure it has the preouts for a separate amp.

    You do have preouts so you can add a separate amp. Do you just have the two speakers or are you planning on adding more.

    We tend to like Parasound amps. It all depends on what you want to spend, and how many channels you want to amp. Are you open to buying used?

    I agree an amp would drive those speakers a lot better. Bass needs clean power.

    Parasound, can't go wrong if you have the funds

    Emotiva, not bad for the price. I've heard the gen 3 are warmer than the older ones. A9 are a bright speaker don't need to add a bright amp.

    Outlaw Audio, Nice amps made by ATI or so I've heard. One system with two of their monoblocks did sound real good. http://www.outlawaudio.com/products/2200.html

    Think I may go with an Emotive XPA-3 Gen3. About $1200 for 3 channel @ 275 W. The Parasounds a little more than I can do. Still thinking about adding the SVS SB-2000. Will get amp first and go from there. Thanks all for the input.

  • I would say if you are going to get a sub you either have to go big or just power the a9s well. These speakers love to suck up power, especially if you are using them for their bass.
    Home Theater Setup
    • Receiver - Onkyo TX-RZ1100
    • Mains - Polk RTi A9's
    • External Amps - Outlaw 2200 Monoblocks for L/R/C
    • Center - Polk CSiA6
    • Side Surrounds - Polk FXiA6's
    • Atmos - 4 Polk 80F/X RT's
    • Sub - SVS PC-4000
    • T.V. - LG OLED65C7P

  • I have the a9s. Love them to pieces but I to have underpowered them. I got 2 subs to go with them. The dsw 660 for both. I started with one it it does amazing with the speakers. I just got curious what 2 would do and my God.... I got them both for cheaper than a good amp would cost. In the future I will definitely be upping my amplification when the funds are good. My reason for going with the subs first is they were both still cheaper than buying a good amp brand new. I've never been a fan of buying used stereo equipment. You never know how people treat their stuff before selling it
