Redefining Power and Value

Predator is devastating when used in dedicated high powered home theater applications, but also transforms the serious gamer’s experience and partners beautifully with active wireless speakers for music reproduction. HT/1508 is a unique combination of lightweight, modern 15” CarbonGlas™ (380mm) driver, coupled to a powerful 800W linear power supply amp that runs cool, producing extraordinary dynamics and consumes merely 20 watts at idle. Internally, we developed specially adapted home theater input filters that produce extremely flat bass down into the low 20’s.

We designed the driver of the 1508 to be light and accurately reactive; theatre sound can and should be at times light, playful, funny and at times terrifying or awe-inspiring. Deep bass that reacts quickly and effortlessly to these changes during a film creates a much more satisfying experience of the medium than typical theatre subs can supply.

As with the entire HT range, Predator’s industrial design wastes nothing on ornamentation for its own sake and delivers a simple, yet satisfying, design that borrows themes of line-grained aluminium contrasting with a sophisticated, polished top surface. Instead of mere feet, Predator uses full depth rails necessary to better cope with the force it produces.


Design Is Everything

We’re known for building beauty in a category not known for it. But our designs do more than look good, substance integrates throughout Predator. If you see a design element, it accomplishes a function as well as delivers style. The 25mm top plate, beautifully finished in 5 coats of hand-rubbed lacquer, serves to damp vibration in the cabinet below. Within, a massive windowpane brace damps both side and inner cabinet walls, yet also does double duty supporting the heavy magnet of the driver. And the attractive (but easily wiped clean) cabinet surface looks like expensive line-grained aluminium, but instead is a tough, sexy composite that serves to keep costs reasonable.


Size Still Matters

At 15” and sporting 3” of fore and aft stroke, the core of Predator’s amazing performance centers around its driver. Film sound and music both benefit from quickness; fast drivers result in accurately tracing music’s peaks or a movie’s explosive special effects with equal facility. Using a bonded composite of lightweight glass fibre for the cone’s body with an ultra-light carbon fibre center mass, REL’s designers have been able to pare excess weight away. The 1508’s cone weighs far less than our 10” driver of just a few short years ago. And this driver is built to last, with high quality materials throughout such as natural butyl surrounds that won’t dry out and fail like foam surrounds can.


Power Corrupts

800 Watts Corrupts Beautifully

Some may wonder why so much power is needed, but 800 watts RMS loafing along means Predator is rarely stressed. When the scene demands, having more than enough power means that the incredible output levels are delivered safely without risk of damage. The amplifier actually outputs peaks of around 1200 watts which makes for massive output. A traditional power supply is used with a huge 1.2KW transformer coupled to a Class D output stage meaning it runs efficiently. Predator demands only 20 watts of power consumption at idle; so little that most will simply leave it on all the time but when on holiday.

Stand and Deliver

HT/1508 Predator offers one more uniquely REL innovation. For truly over the top performance, Predators are designed to be stacked up to three (3) units high using included REL Couplers™ that connect lower units to upper units. These solid, milled aluminium couplers bolt securely to each sub and along with the substantial rails on the underside of each cabinet create an extremely heavy, sturdy tower of bass. When used in stereo stacks (6 total, 3 per side) it represents over 7000 watts of peak power forcing (6) x 15” drivers to give their utmost in the service of breathtaking bass delivered in oceanic torrents of bass.

You need the 1508 / HT 3D

I have a 17'X18' room with 12' ceilings and because of the pandemic, dove into home theater. Upgraded the the front three speakers, installed Atmos and rear surrounds, new receiver and because of budget constraints, bought the REL1205 as my main sub. Life was good and family and friends were impressed by the 1205. A year later I wanted to delve into the REL 3D home theater experience so I bought the 1508 Predator. Wow! What a difference. Now this is a real movie theater experience! Let me say this, unless you have a very small room, skip the 1205 and get the 1508 and if you don't believe me, get both and see the difference I guarantee you'll be bringing the 1205 back and you'll talk yourself into the double price of the 1205 for the HT1508.

It's not just the deep bombastic bass, it's every little quiet rumble, this sub immerses you into the movie you're watching effortlessly. Unlike before where I was turning the volume up to get the movie theater experience, I was turning the volume down with the Predator and having double the experience and a more balanced sound. After the wife heard it she instantly approved the purchase because everything sounded better and not blasting loudly as before when I was pushing the HT1205 to try and do the same thing. It makes such a difference I have to rewatch all my movies again. The HT1205 is now my rear 3D sub and adds to the HT1508 and I bought the REL T/5x as my center channel sub. I turn each one on and off and notice the difference when one of them is not on. You don't notice all 3 on, but turn one of them off and you notice it's missing. Yes, the HTs are only running the LFE channel so down the road the plan is to eventually upgrade to a stereo pair of S/812s and the S/510 as the rear channel surround sub.

Superb versatile subwoofer

I am writing this after listening to the HT 1508 for a month. First of all I would like to thank Yorkshire Jim for his advice to me on this wonderful subwoofer. I had 2 other popular brands in mind (one of which I was using) along with the Rel before purchasing the HT 1508.

HT 1508 is a very good versatile subwoofer for music & movies. Having used a ported sub & a sub with a passive radiator before, I don't miss the low end extension with this one. It is fast , tight , musical & impactful.
The build quality & looks are a bonus apart from the quality of bass it gives. I would suggest prospective buyers to definitely hear this one out. The only negative I could think of was that the glass top would attract scratches and dust over a period of time. Wish it had the brushed metal finish covering the entire top which looks very classy & does not attract fingerprints. Thanks a lot Rel.

More Than Satisfied

I've purchased from several subwoofer manufacturers over the years, but I didn't really know what I was missing until I walked into a popular audio/video dealership 17 years ago and heard music coming from a display room from across the store. The system had a REL sub I had never heard of before and I was hooked! Loved it and bought it right off the floor. The sub became a beloved member of the family for those 17 years. (It lasted longer than the dealership).
It would be easy to write all the positive things about these subwoofers but you would do better to explore the site and get a much clearer descriptions of what is offered. The staff is knowledgeable and very helpful as well.
I will say two things; the first is specs can be deceiving. True depth of play in your own room is the final test, of course, but the REL's ability to couple to your speakers and pressurize the room with satisfying, deep, articulate bass is stunning. I fully believe there is a REL model that can fit in with any system out there.
The second is longevity. Stretch your budget if you can because these subwoofers will become the foundation of your system(s) for a long time.
The 1508 has astounding agility in a home theater setup and it's ability to play music is equally amazing. Fast and tight.
As far as I'm concerned, money well spent and I'm more than satisfied with the HT/1508 Predator.

Carnage Bass

I’m coming from two SVS PB2000 Pro subs. So I’m used to great controlled bass. But the Predators are what I would call “carnage bass”. Did an REW sweep with one turned on, good response down to 10hz (I kid you not, though I did put a HPF on to drop the response of quickly under 20hz in the end), natural couple of db peak at about 35 hz, then a big null around 100hz (caused by my room). Turned the second predator on, increased SPL across the board all the way to 10hz and no nulls. All I did was flip the phase, pretty much seamless flat integration out the box with no DSP with my mains. John Wick 3 punches slam your chest and the shot guns near the end, next level. It’s all so controlled, which is the key difference between these and the SVS. The 15 inch driver just adds so much weight, but being a sealed unit it retains its agility. Amazing result. They sound awesome.

The HT/1508 Predator with Wireless HT Air is simply the best!

I have been an audiophile for many years and wanted to put a clean wireless setup in my living room without spaghetti wires everywhere. I did not want to sacrifice performance, hence; the HT 1508 wireless. Not only does this subwoofer look and sound amazing, is blends in perfectly with my current setup-sonically and visually. I am very happy with customer support with REL. I will be a customer for life as I add new products in the future.
