  • Overall the R-120SW is amazing.

    Overall this subwoofer is amazing. I purchase this sub to replace a Polk Audio PSW108 that i purchased a couple months ago. There nothing mechanically wrong with the PSW108, it just wasn't loud enough. I definitely wish I would of just bought the R-120SW months ago instead. Now let me tell you why I say the R-120SW is amazing. - This sub can get loud, I mean VERY loud. (If you live in a apartment don't waste you time, It will be too loud for you. This sub shakes my house, you can feel the bass) - Not only can it get loud, but sound good at the same time. Sound quality is excellent. - The built quality is top notch. - The amplifier remains cool to the touch after long hours of playing at high volumes. - The sound complements Klipsch Floor Speakers very well. Everything I listed is what great about the sub. Let me list the cons I've noticed. - The auto-on function does not work very well. (There is a few seconds of delay before the sub starts to play. Polk Audio PSW108 was quicker.) - There is a slight hum/buzz that appears when you turn off your AV reciever. - The Gain knob is too sensitive.(The db increase is not consistent.) That pretty much sums up my review. I highly recommend this subwoofer. As a tip, give the sub about 10 hours of play time to get the full sound. The woofer is a bit stiff right out of the box.

  • The sub rattles
    by Steve

    on 1 décembre 2019

    I just bought this sub on a pre-black Friday sale for about half price and at first it seemed okay and at least worth the half price amount but having it just a couple of weeks and I start noticing a rattle on the inside and now the sub is rattling like the dust cover is loose or something. I unscrewed the sub and pulled it out and looked inside and they do have some bracing but it looks like the whole box is held together with hot glue and I think that's what I heard at first is the box rattling from voids in the glue
