three celestial bodies are perfectly aligned, it’s called syzygy. When
advanced technology, high performance audio and a passion for great
sound align, we call it syzygy too – Syzygy Acoustics.


                          Rooms are the real problem

subwoofers pair seamlessly with any high-fidelity or
home theater audio
system to deliver clean and powerful low-frequency sound. Thanks to
Syzygy's proprietary wireless technology, you can link multiple
subwoofers to the same transmitter, allowing you to fill your space with
deep and detailed bass, regardless of room size
unique SoundSculpt technology measures your room and defeats room
resonances to allow a seemless match to your main speakers without the
typical one note bass appearing of most rooms. All controlled from your
listening chair right from your phone on the Syzygy app.

unique SoundSculpt Technology, each Syzygy subwoofer essentially makes a
3-D sonic map of its space, and then adjusts its output to smooth out
the aural peaks and valleys. It sends out a series of tones that measure
the shape and size of your room, the position of the furniture, and how
your decor absorbs and reflects sound. This rich acoustical data is
captured by your smartphone and sent back to the subwoofer where it is
corrected then perfected, ensuring that the sub-bass from the Syzygy
subwoofer blends seamlessly with your speakers and the low-frequency
sound arrives at your ears at the correct time. All with a tap of an

                      Multiple subs are the way to go                                       

acoustic experts will tell you that multiple subs are the way to go. Two
subs or a swarm of 4 will couple better to all rooms and help to even
out room modes and allow for lower distortion along with greater
dynamics. Instead of making larger models Syzygy recommends using two to
4 subs in your room and this can be done at very reasonable prices. We very much agree. Two 850 subs are the same price as a $1600.00 REL or JL
and easily outperform them.

SLF-850 is a 10 inch acoustic suspension design with a 1000 watt amp
and true 24Hz performance. It can be run both front firing or down
firing. In addition to wireless operation it offers line level input.

Performance is superb with vary fast transient response and the ability
to keep up with fast mains like planar speakers.

At only $799.00 the SLF850 is a great value and at under $1400. two will rock even very large rooms. Four in a swarm is amazing!

The Tone Audio Review said:
"But regardless of whether you add
one or two of the SLF850s to your system, fine tuned, low-frequency
extension is easy and affordable. Thanks to the wireless, DSP
configuration and the small form factor, I can’t think of anyone not
being able to integrate at least one of these into your listening room.
You’ll be glad you did. I’m adding the
review samples to my Audiophile Apartment system, so you’ll be seeing
and hearing more of them in reviews to come."

compliments to Paul Egan and the staff at Syzygy for delivering an
outstanding product at a very approachable price; earning them one of
our first Exceptional Value Awards for 2017."

In the CE Pro review they said:

subwoofer killed it. Articulation, depth, detail, power, control,
tightness, funkiness… you get the picture. I was able to discern the
warmth of Keith’s bass, just like when I was running it through the PA
system. The punch of Garry Tallent’s line on “Fire” hit you in the
chest. Al Green’s entire record sounded like soul records are supposed
to sound, with a bottom end you could dance to. Classical music sounded
exquisite, with definition."

could go on, but you get the picture. I have no doubt movies would have
sounded fine, but for this review, I strictly used the subs for music

"Doubling up the subs only made it better, providing more uniform coverage wherever you were in the room."
