Products are great! Service is even better!

I'm continuously impressed with RSL, their products and the prices are currently some of the best, if not the best, in the biz.

If you're considering trying them out, don't hesitate. Their customer service and after purchase support will help be the difference maker.

They also do a lot of the work themselves so you might speak with one of the owners or at least whoever helps you when you call with definitely be close to the products and knowledgeable at the very least.

I bought the 12s and it's AMAZING. I'm constantly impressed! I was looking for Bass Extension and I got it with this.

Cheers RSL! Thanks a lot.

Well I kinda miss my 10s

I got the 12s hooked up and removed the 10s.
The 12 is a great sub. Super for home theater.
But I think I enjoyed the 10s more for listening to music.
But the 12 is still really nice. It has a lower range and more thump.

12s Pair In Basement

45 days in with these subs has been an up and down experience. The downs were the first 30 days. The ups came shortly after that. Anyone who doubts that break in is real, let me tell you these subs really started coming alive for me after around 40 to 50 hours of intense music and movie playback. I kept turning up the gain at the beginning, but it didn't matter. After the break in period, I now have to turn down the gain. These boys are big but they sure can bring the bass. My concrete basement is murder for most subs. The pair of RSLs are giving me the level of bass I've been craving for many years without draining my bank account. Yes I considered the other brands like JL Audio, SVS, HSU, Rythmik, but RSL offers the best bang for the buck for me.

Got My 2nd SW12S TODAY!

I purchased my 1st SW12S one month ago and was BLOWN AWAY! I received my 2nd one today and again, I’m BLOWN AWAY! Deep, immersive BASS that is smooth, punchy, and all around PHENOMENAL! I advise anyone with the budget and the space to purchase 2 of these Big Dogs! You won’t regret it! Thank you RSL!

Speedwoofer 12S and RSL Speakers

Excellent subwoofer. Came from a Klipsch Cinema 600 (had a 10in sub). Would bottom out on certain songs/movies and sound a little boomy. Obviously, this blows it out of the water. Doesn’t bottom out for me anymore (love bass) and the 12s just keeps going with very precise hits. House rattles more than ever and can actually feel the bass through my couch now. T-Rex scene in Jurassic park is phenomenal. The thumping of the steps and growl of his breathing makes me feel like I’m in the Ford Explore with the characters. Have it sitting in the front right corner, bass at roughly 50% (use remote all the time, very convenient depending on source of audio). Room is 16’ x 18’ with vaulted ceiling to 17’ and this sub provided plenty of bass. I did upgraded my speakers to 3 RSL CG23 speakers for front speakers and 2 CG3 for rear. 5.1 setup. Integrates very well with 12s sub. Using Denon receiver with 165watts per channel. Plenty of power for these 4ohm speakers. Clean sound with no distortion at my listening volume (around 85-90 decibels when playing loud) for my room. Was contemplating Sonos initially, but love bass. This provides so much more sound for half the price.

Meticulously crafted for excellence
