Coverage note. Speaker Ranking currently covers 4 REL Acoustics models across subwoofers (plus 1 not yet ranked). These are the products in our database, not a complete list of everything REL Acoustics makes.
What this page covers. The REL Acoustics models ranked here span subwoofers, including REL Acoustics R-528, REL Acoustics T-7 and REL Acoustics HT/1510 Predator II. Use each model’s category position to compare it with alternatives of the same size and use case.
This page lists all 4 REL Acoustics speakers ranked on this site across subwoofers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Small Home Subwoofers (Under 30 lbs)
Ranked #48 of 48 in Small Home Subwoofers (Under 30 lbs) - REL Acoustics Tzero MKIII: $599.00 Amazon eBay
Pros: Independent CEA-2010 testing records 89.2 dB through 40-80 Hz. The sealed enclosure with 6.5” (165mm) driver is intended to add useful bass support without a full-size cabinet.
Cons: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 241.3H x 215.9W x 266.7D mm cabinet and 6.8 kg mass still need careful placement and calibration.

Medium Home Subwoofers (30-75 lbs)
Ranked #70 of 146 in Medium Home Subwoofers (30-75 lbs) - REL Acoustics R-528: $1999 eBay
Pros: 12-inch carbon-fiber passive radiator with 500W RMS Class D amp reaches 21Hz. Fast impulse response best in REL series. Breathtaking bass reach and low distortion in compact package. Speed and detail-oriented musicality. Premium fit and finish.

Large Home Subwoofers (Over 75 lbs)
Ranked #82 of 109 in Large Home Subwoofers (Over 75 lbs) - REL Acoustics HT/1510 Predator II: $2,526.62 eBay
Pros: Independent CEA-2010 testing records 98.0 dB at 20 Hz and 118.1 dB through 40-80 Hz. The sealed enclosure with 15” (381mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 457.2H x 541.0W x 492.8D mm cabinet and 45.2 kg mass still require deliberate placement and calibration.

Still ranked, and often still worth buying used, but no longer in production. Check availability before planning around one of these.
Medium Home Subwoofers (30-75 lbs)
Ranked #103 of 146 in Medium Home Subwoofers (30-75 lbs) - REL Acoustics T-7: $699 Discontinued eBay
Newer model: the REL Acoustics T/7x. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: Compact 8-inch with 200W RMS stays extremely solid and composed at high volumes. Fast agile response ideal for music with speed and depth. No overhang or bloat. Excellent Speakon connectivity and build quality.
Cons: Discontinued.

REL Acoustics Models Not Yet Ranked
Newer or recently added REL Acoustics models we track but haven’t ranked yet, because no measurements we can rank them on have been published. See speakers not yet ranked for how that works.
Not yet ranked, replaces REL Acoustics T-7 - REL Acoustics T/7x: $1,299.00 Amazon eBay
Older model: the REL Acoustics T-7 (rated 3.6/5).
Pros: Sealed subwoofer with a front-firing 8-inch driver and a down-firing 10-inch passive radiator, driven by a 200W Class A/B amplifier. REL rates extension to 30Hz at -6dB. A high-level speaker-wire input and an RCA/LFE input can be connected at the same time for music and movies.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. There is no app, EQ or room correction, and an 8-inch driver limits output in a large room.
