      Well worth it

      After finally moving out of apartments that banned subwoofers, I finally found a spot to live where I can own one - and after setting this up and turning it on for the first time, I completely understand why these were not allowed in apartments.

      Makes good bass but shares the same remote fault

      Makes good bass but shares the same remote fault as The Fives McClaren Edition. The infrared remote control only works reliably when you're within 3 feet of this speaker. Otherwise, it works as expected.

      You need eq capabilites and its far from perfect. But for the price it makes compromises in the exact right places if you value just nice, clean, tight, light and powerful bass its very good. And it looks great too!

      Bought this sub to supplement my R-40PM's. I'm still playing with the gain/crossover configuration, but the base travels and has a great punch. This will certainly shake your kitchen glassware and knock you out if you turn it up! I got the y-splitter cable to connect the sub to the speakers because I guess you can get better (double?) output..from one novice audiophile to another.

      Received very quickly and in great shape. Hooked it up and Wow! We have been w/out a Subwoofer for years and the R-121 delivered in a big way. Great sound and there has been some heavy bass put through it. Also appreciated that this product is made in the USA 🇺🇸 Very happy with purchase.
