Question: Will this subwoofer work well with a Yamaha RXV573 805 watt, 7.1 channel receiver?
Document: I was very releaved as one of our biggest arguments ever was over speaker placement.Sound: I have the Klipsch Quintet SL's main speakers(very nice) and a Kenwood receiver with 100 watts per channel. The Yamaha blends in very well with the main speakers. I have a very wide range of taste in music from classical to rock and I can't find any faults with this sub.
This sub delivers punchy and clear sound. You might find these settings and adjustments useful:1. If you have a Yamaha receiver, set front speaker size to SMALL. If you set it to LARGE, the receiver will send low-frequency sounds to the front speakers and not to the sub.2. Set crossover frequency on the receiver to 80-100hz.3. Subwoofer volume is set to 40% on the receiver and 20-25% on the sub. This sub is too powerful.
Makes the whole house rumble (when I want it to). This subwoofer exceeded my expectations. Classy look and just as advertised. My TV room is complete and sounds great with my 7.1 system
Not a real sound expert, but WOW this woofer really sounds great, and even I can hear, and feel so much more out of my DVDs. Have a Yamaha 7.1 surround sound amp, and a and am really pleased with what this 42+ ponnds of speaker has done.
I bought this sub for my master-bedroom setup and it's more than enough. It fills the room with nice deep sounds. I have it paired up with a Yamaha RX-N600 receiver, Boston Acoustic in-ceiling speakers, a Yamaha Center Channel speaker and a Samsung 50" Plasma. Overall sound is perfect for my needs as it is only the master-bedroom and not the theater room.
Auto On feature essentially didn't work. Came on a few times, but usually didn't. I tried a variety of digitally recorded CDs with significant bass. Tried various settings. Nothing helped. After 3 weeks of frustration, returned product. (Hooked up via LFE to new Yamaha receiver.) Replaced with Polk PSW 110 with similar features. That has worked fine. I have 2 Yamaha recievers, a CD player, and a digital(hybrid) piano. Love them all, but this product just didn't work.
This Sub is simply amazing. Hook up is a snap. It outputs tight and clean bass with no distortion even at high volume. It has multiple inputs and even has two Low frequency Extension (LFE) inputs just in case you have high end Receiver that has two LFE outputs. I previously owned a SonySony SA-W2500 Performance Line 100 Watt Subwooferwhich has sub-par performance. This Yamaha is in a class by itself. It does not only produce dynamic bass but is a classic piece of workmanship to boot.
The Auto-Standby switch  DOES work. You need to have the power switch switched to "ON" and the button on the front needs to be in the "ON" position as well. I keep mine switched to the "High" position which means as soon as the subwoofer detects any sound coming to it, it will turn on.
My home office measures roughly 16' x 18', and this subwoofer is able to fill that room with gut-rumbling bass very well. I leave the SW315 in auto standby mode at all times, as I find this feature to work very well. It should be noted, however, that there is about a 6-second delay before the subwoofer begins working, after it receives a signal from your audio source. This may prove annoying for those that use the subwoofer for music.
Well there is always a first time... The Yamaha smokes the Polk sub, I returned the Polk immediatly.Of couse it doesn't compare with the Energy S12.3 I use in my main music system, but for 1/5 the cost, I never expected it to.
Answer: If the receiver has a subwoofer pre-out (which the specs say it does), you can certainly connect it to this sub.  Another factor to consider for this or any sub is the crossover function.  Ideally you want to let the receiver do the bass crossover.  The easiest way to do this is if the sub has a crossover bypass, which this sub does not.  However, you can just turn the crossover knob up to its highest frequency setting, so that it won't filtering any bass from the receiver.  This works fine for me on my Denon.  You may also have to play with the sensitivity switch so that the sub auto-on/off feature works.  On my Denon I had to set it to the higher setting or the sub wouldn't turn itself on.
