REL Acoustics | Home Theater Subwoofers

It’s ALL ABOUT SPEED. The incredible clarity and illumination of

soundstage becomes possible when carefully placed stereo pairs

of REL are carefully positioned near the main speakers where their

speed and body can integrate seamlessly with the highest performing

speakers extant. Incredibly fast filters, amplifiers and drivers.


Some subwoofers excel at theatre sound; playing loud

and extending deep. But ask them to play music and

suddenly they’re wearing snowshoes on ice. REL’s T/9x

is that rare bird; one that’s incredibly versatile, fulfilling

every role imaginable for a subwoofer.


Serie HT is designed specifically to answer the challenge of creating

affordably priced, exceptionally dynamic, pure home theater powered



T/7x is, without reservation, one of the most-balanced

RELs of all time. In order to achieve perfect balance, a

sub must weigh speed against heft, while ensuring true

extension-depth-and do so in a physically harmonious



While the 212/SX thunders and shakes foundations,

it also resolves detail and restores midrange warmth

to its correct balance.


“A friendly warning: A pair of S/812 changes

the personality, the emotional output, of a

system. Further, to a substantial degree it

changes your relationship with familiar

recordings. And prepare to feel a little

deflated when you remove it from the system.

It’s like air being released from a balloon.

Enjoy your entertainment on a grander scale with the

T/x collection. Experience a robust full range of sound

while maintaining premium-grade quality in the latest

REL models. Make no sacrifices, keep the vibes strong

and the sonic balance optimal.


One adds shattering dynamics and insane effects

levels; the other turns your living room into a

3-dimensional circus tent that, with a flick of the

source selector, plays music like it is inside a concert hall.


The job of any range topper for REL is to deliver more of

everything, particularly output and dynamics. The 9x is

no different in this regard, as it delivers the goods in both

music and theatre applications.


No.32 and No.31 represent the pinnacle in subwoofer

design and engineering. The absolute maximum in

power, finesse and beauty on offer.

“The REL HT/1205 MKII is another beautifully built subwoofer from

REL’s Serie HT line of home theatre-aimed subwoofers. It delivered

an authoritative low-end performance, with a highlight being its ability

to reproduce punchy, tactile bass impact.”


“Between having the RELs on and off, the difference was huge.

There was much more body and soul to the singers voice with the

RELs, much more overall presence to the music, more grandiose in

scale, and overall more fullness, warmth and richness to everything.”

“A lifetime investment…I’ve had a few subwoofers

and they’re always great. This REL/S510 feels like

it has been the smoothest, most impactful one

I have heard so far”

We make subwoofers. That’s it. Nothing else. No distractions. Nothing to steal our focus. No kidding ourselves that we can be good at everything. No trying to conquer the whole world. We just do our best to conquer our bit of it.

Each day we come in to work in pursuit of only one intention, to produce the most raw, perfect, pure sound possible, to capture the raw intention of the artist. We use the best quality materials, employ the most exacting construction requirements. We think of the problem holistically. We pursue the chase of the perfect experience of sound with an obsessive passion and vigor.

We do it because we love sound. We believe sound can move people more than any other sense. We believe it’s the integration of the bass via the perfect subwoofer that makes everything else better. And, ultimately, there is a great deal of satisfaction to be gained from doing this well, creating something of unique quality, such that you know it is going to inspire. It makes the hard work and the obsessing over each and every detail worth all the effort. That’s our reward.

In the oil trap, coarse wastewater treatment takes place on absorbent filters based on a fibrous hydrophobic material made of propylene. The sorbent is a non-woven fibrous material formed into a three-dimensional structure from hydrophobic polymer fibers fastened together. With this method of formation, additional capacious cavities are created, into which oil freely penetrates upon direct contact, fills the entire volume due to capillary forces, while firmly holding inside the corrugated fibrous structure of the sorbent due to adhesion and easily separated during squeezing.

Contamination concentrations of oil products and suspended solids in purified water correspond to the indicators for further discharge of effluents into the sewer networks of the city or underground filtration fields.

The concentration of pollutants in the treated liquid after OT is determined by the concentration and dispersion of particles of pollutants in the wastewater at the facility inlet, as well as compliance with the maintenance schedule.
