Well suited 9.2 and 11.2


from Birmingham , Alabama  -  Tech Savvy

First off I would like to say that these speakers are real nice on sound and appearance!! Some time was put into making these speakers. Now I am using these with the rx-a2020 which will soon be replaced with rx-a3040 and I will add that there is a difference when you use the front effect speakers the sound stage is a lot better when you are not using them. because when you don't the receiver downmixes the sound into the front channels so in other words its overtime for the front speakers. also I will add that the speakers can handle a lot of power too. so they are not weak at all.

Perfect poof - out the port


from Almaden Vlly. Santa Clara Co. CA

I get a thrill at feeling the Poof comeing out the side port. The louder the Poofyer. I believe that the Active Servo System and sound dispersion is what sets this subwoofer apart from others. I kicked out my last "front firer" (second sub. used with RX-V675)For lack of thump, behind the listening recliner. Yah, I know how to live. Paid twice as much for it in favor of my now new YST-Sw012. We will see and hear a big difference when it arrives. I am sure of it! Well, hopefully

A Rare Product


from Pago Pago, American Samoa headed to Fiji  -  Long time audiophile

I use this unit with a pair of Audioengine 5A+ in the medium sized salon on board my 40 foot yacht. If you listen to music (classical as I do, or heavy beat rock) this subwoofer is perfect. If you prefer to listen to earthquakes and knock down walls, you should try something else.
