Feel Every Dimension of Your Music

Had a pair of S/510’s, then did the line array with these S/550’s and find the results more incredible than I could have imagined; no gaps, extremely fast, hardest punch I’ve experienced, and paired with my MBL’s make the best system I’ve been able to listen to. So happy with these!

The next best thing to owning the best in its class product is the outstanding customer service & support team of REL. Any question and need I’ve put forth is taken care of quickly and thoroughly. I could not ask for more than that.

This S/550 delivers bass that is deep, articulate, and astonishingly fast. I believe that the REL’s High-Level Input is the secret weapon here. It allows this S/550 to blend seamlessly with my main speakers, creating a more cohesive, full-range sound...

I've used and loved their subs for over a decade. I own 4 of them. But I never needed their support until I had a question about new amps recently. Now I also love them for their thoughtful, detailed responses and help. Excellent company and great subs !

I bought the T/9X SE to replace my somewhat larger, 90's vintage, Acoustic Research 12" sub and the difference in bass quality and depth is remarkable! I'm hearing and feeling bass that very deep and fast that it makes me wonder how it's all coming from such a small package. Love it!

I have two of these 1510 in my system. These subs compliment my Klipsch Cornwall IV perfectly!! Not boomy and no gimmicky app just dial them in and enjoy pure musical performance! If you didn't see these you would not even know they are there,they blend perfectly!

I've now purchased two pairs of Rel subwoofer. S510 and now Carbon Special Black Label. On both occasions pre sales engagement has been responsive and helpful. For a single post sales warranty issue they were equally responsive and helpful above and beyond. This is what make company you want to return

As with many high-end products, specs do not tell the entire story. REL subwoofers sound better. They blend better, and it is a small company with dedicated people that still care about the customer's experience. Don't shop specs, shop sound!

REL is awesome🔥🔥🔥. Just buy one. No need to look at other subs. Seriously. No need!!!
