    How to add 2 more speakers with existing 9ch AVR?

    Yeah, look at those videos that Dave Upton linked in my subwoofer integration thread. Prepare to lose some afternoons and weekends, but you will be able to put to rest any doubt that your system is performing the best you can reasonably achieve. Just do some experimenting to see what the...

    How to add 2 more speakers with existing 9ch AVR?

    How I did it was to integrate each sub separately using REW, then with both of them running, adjusted the phase to 90 degree one at a time and found that the result was the smoothest with the rear sub at 90 and the front at 0.

    How to add 2 more speakers with existing 9ch AVR?

    Yeah, that's the mic. Setting up two subs isn't necessarily that different from setting up one, except you need to deal with the phase between the two subs. There's several ways to address this. I started THIS THREAD for general sub integration, and will be adding info regarding integrating...

    How to add 2 more speakers with existing 9ch AVR?

    The problem is, the sub crawl isn't terribly reliable. It can actually lead you to choosing locations with a large peak, instead of the smoothest response. You also can't judge the response of the two subs together. If you're willing to do the work, spend $115 for a calibrated MiniDSP...

    How to add 2 more speakers with existing 9ch AVR?

    Dual subs are awesome. They can really solve a lot of room interaction problems. I went to dual SVS SB-16 Ultras back in May myself. After doing research, as well as guidance from HTF co-owner Dave Upton, I rearranged my HT room to facilitate opposing corners for placement. Many people who...

    That’s definitely an option. That’s how I would configure it.

    How to add 2 more speakers with existing 9ch AVR?

    I would just wait for the A-3. It's a new amp and it's the first inexpensive 3 channel amp I'm aware of. Hopefully it won't be too long. Just sign up to be notified when it's available.

    How to add 2 more speakers with existing 9ch AVR?

    You can do this and it's actually fairly simple. Your receiver can process 11 channels, so you need an additional two channels of amplification to go to 7.1.4. However, I highly, strongly recommend you use the external amp to power the front speakers. Not Atmos ones. If you look closely at...
