One of the few companies that take pride in their product by actually answering their customer's inquiry on a timely basis. Love the product, love the customer service.

Excellent subwoofer. As I think the manufacturer of my main stereo speakers gilds the lily in saying they’re-2db at 34hz- complete rubbish- I set the s850 crossover at 80hz. Higher than recommended, but I want a low note on a cello (65hz) to sound real, and a note below 100hz on a grand piano to sound big: in reality a Steinway Model D (which I own), has a big sound. My speakers produce a restricted almost constipated bass. The s850 with cross over set at 80hz remedies these mediocre speakers

Had a problem with rel arrow v3 causing humming through subwoofer,contacted Rel on line describing said problem was contacted morning after and within 2 days received replacement send and receive transmitters,great response and brilliant service. many thanks⭐️⭐️⭐️⭐️⭐️

After buying my first rel (The T-One) I would NEVER consider buying another brand of subwoofers. I probably wouldn't take another brand if it were free. . . . . . . well I guess I would and then I would sell it and buy another Rel!!!

When I purchased the unit several years ago, I also contacted your customer service. Both of my encounters were very positive. Associates were helpful and timely

Amazed at the knowledge of your advisors. REL has a subwoofer for every size room. Being a retired Physicist I'm "VERY IMPRESSED" with REl utilizing science as its approach to quality and sound instead of gimmicks, or unnecessary electronic voodoo used by competitors.

I was a little confused when hooking up a new pair off Carbon Special Black Labels and the retreat worked with me and TMR together it resolved. Love the subs!

Well, it was not completely smooth, but in the end all worked perfectly. My replacement driver is perfect and sounds amazing, how it was initially developed. A bit strange gap of spare parts cost from EU distributors comparing to direct purchase, though. Anyway, happy to deal with the customer's support and orders support teams. Thank you!

Great company to deal with - impressive Customer Service.

J’ai pu bénéficier d’un service après vente de grande qualité, je remercie en particulier Wendy pour son efficacité et sa gentillesse pour le dépannage d’un S510. Merci à vous

Fast response great to work with

Everybody has been amazing. Went out of their way to make things right.

I have a older REL sub. I own the S3 SHO. I have owned many subs by other well known companies. REL subs are a high quality product in looks, build, components and sound. There is no other sub in the market that performs how a REL performs. (REL is not something you listen too, REL is something that you experience). REL customer care is far superior then any audio brand that I been in contact with. My REL sub is the most substantial positive change in my system. It was NOT DAC's, streamers, amplifiers, speaker cables, power cables or stuff like that. Yes lots of those things make difference. Some more then others. Stop switching equipment constantly in and out and save that money. Do yourself a favor and buy a REL acoustics sub. Also listen to the wonderful people at REL Acoustics, and buy the sub they recommend. They only do subwoofers, and they are the only subwoofer you should buy. Thanks REL for your hard work, passion and dedication.

Very responsive, knowledgeable and friendly service.

I'm a big fan of the REL products, not just because of their looks, but because I spent months researching and listening to them (especially the T/9x that I'm interested in buying—actually, two of them!). ​But I also have to emphasise the quality of the amazing Help and Support Center they have, ready to resolve any problem and answer all my questions! ​I can't recommend them enough!!! ​Thank you so very much for all of your help!

I was somewhat 'at sea' in setting up my REL subwoofer but the customer support (via email) was excellent. It took a couple of days to get a response but one would come providing answers or suggestions in a patient manner.

REL shipped me a replacement plate amplifier quickly and it is back up and running!

About this subwoofer about 8 months ago I went through a variety of subwoofers over the last 5 years they were okay and best from the Klipsch reference subwoofer to the Klipsch reference premier subwoofer Sony. . Dayton audio. . and Polk audio and they were okay at best, been Crutchfield knew what kind of Base I was looking for and they talked me into trying this ht1003 subwoofer and at first my expectations were very low because how small it was and then once I got it broken in I was absolutely blown away. It makes music sound absolutely beautiful. I mean just gorgeous how it flows naturally with my Klipsch reference premier speakers. I've got a 5. 1 connected to a Marantz Cinema 70s receiver and it makes music sound. Amazingly now for movies for a small 10-in 34 lb subwoofer my jaw hit the floor when I heard the impact this subwoofer makes. Don't let this little subwoofer For you because you can watch movies like transformers and different war movies and horror flicks and the LFE impact. This thing can do is jaw-dropping and I mean paying right there with my speakers in a living room bed 20 ft by 20 ft. I am 10 ft away from my listing position and this subwoofer makes a big bang. I banged that subwoofers twice this size cannot do bigger subwoofers struggle with to keep up. They can start and stop them and dime. I highly recommend the subwoofers. I don't ever see me using a different brand ever again and I truly mean that they are a company. They focus on subwoofers only and that is a rare thing For those that say oh they don't get down low like SBS which I've heard and I did not like got to remember they do it without DSP. And here's a thing is this subwoofer goes down to 23 HZ and it does every bit of 23 HZ without DSP, I do not see the point in going below 20 HZ anyway, I just can't wrap my head around. Why does it matter to go below 20 HZ but anyways nor here or there then subwoofers highly highly recommended if this 10-in subwoofers can do this kind of Justice...

Great service helping me to connect my subwoofer up after emailing for help! Thank you!

Very helpful advices. Great reactivity.
