The main cause of sound problems

If you search the web for used speakers, you' ll see many ads from audiophiles, and in their speakers' pictures you will rarely see proper room treatment; either no bass-traps, no sound panels, or no carpet... Not always; but over half of audiophiles have little to no room treatment !

Most of them "know" that if they would treat their room the sound would get "a little better", but to "know" is NOT to truly "understand".

Then they upgrade their amp, or speakers, DAC, wires, turntable, and they really do get less boominess, but there' s still a bit; less harshness, but still some on high pitch tracks; clearer mids and vocals, but still grainy on some recordings; less ear fatigue after 1 hour, but still a bit ...

(1). The fact is you can get a 10 k DAC, with a 20 k tube amp, 7 k wires, and some 75 k speakers ; here is what your walls are still doing : high frequencies bounce on 2 walls, floor, ceiling, all adding up with direct waves of the tweeters to your ears, but all out of phase in waveform and timing, for different distances traveled, creating harshness - shrills - ringing (2). (3). Louder sounds in the mids bounce and add up to even louder, hiding subtler details; also all out of phase, coloring tones and timbres.

De-phased overlapped waves blur - shrill - boom

The lows and bass add up and blur - boom - dull more than anything else, going right through wall panels, requiring 6 inches thick, 24" x 48", absorbing medium (bass-traps) in the corners, where those waves naturally converge. Thus rendering the bass less boomy & more defined to an "acceptable" level, but never completely.

All that happens NO matter how pricey your speakers are, or how fine-tuned your system is ! ( Even if your room is very well treated, it occurs (less) with the 40% wall-floor-ceiling surfaces not covered. )

So WHY let the sound waves get to the walls then ? Nobody is listening there with the head stuck against the wall ; everybody knows it only creates problems .

Answer : It would take 9-inch-thick panels on each sides of the speakers, the energy being much stronger close-up ; or maybe because nobody seems to have thought of it before Sylvain St-Pierre ( Soundexman & Black-Holes speaker-treatment creator ) .

Room sound treatment, acoustic bass trap control, clearest details soundstage focus. NO harshness !

BLACK-HOLES "Warp10" top model

So the solution, the concept: design a lightweight system, no more than 2 inches thick, that very significantly reduces ALL frequencies, and easily holds 4-6 inches on both sides of all drivers, looking nice & not bulky, still letting sound touch walls about 7 feet in front of speakers, harmonizing phases to a soothing and immersive sound from bass to highs so much, that you' ll never want to go back; meet the Black-Holes acoustic treatment !

** To stop most of even the bass frequencies you need much more than 2" of fiberglass, the technology breakthrough in the Black-Holes is a proprietary lightweight aluminum frame & two 4" x 28" aluminum kinetic resonators in each side-pad.

First, they reflect the mids & highs back into the pad, diagonally traveling 5 to 7 inches of superior fiberglass before exiting a little bit. Second, they resonate and vibrate with the lows, transforming the sound waves into kinetic energy (movement), using up most of their energy (See ACOUSTICS ).

You can actually feel the vibrations with every bass notes & sounds by lightly touching a frame or a resonator !

Instanteneous immersion !

As soon as you hear all instruments in true harmonic phase, you feel elsewhere ; you go into "soothing chock"

Your bass will hit you !

"Surround" - like soundstage, even off your chair !

Instanteneous immersion !

Maybe the most striking effect: the bass goes 20 to 30% more present, louder ; and so clear you can distinguish every note !

Technical explanation maybe complex but : "Amen" to that effect...

A welcome silence in between notes, thanks to the best echoes-reducing system ever.
Total lack of ringing in the highs, try some songs with highs you dislike !
Nice decay of long notes, you will notice when they end.
Hi definition of your soundstage, showing the instruments that are in front, and the ones a few feet back. Some sounds will go a bit beyond the outside of speakers.
A different resonance & decay for each specific instrument, each with their own tone and timbre.
You will distinguish the bass notes & melody in every song or piece, even at low volume.
Clearly hear every time a vocalist sings a word or phrase synchronous to the singer' s louder voice.
Truly punchier, louder, and clearer bass, so tightly in tune with higher octaves it feels like flying on a bass cloud.
The singer' s breathing, modulations from troat to sinus voice, subtle tone changes, are revealed up close & personal.
Discern vocalists distinct voices, more upfront and organic, like singing as a group, try some Elvis and hear the difference !
Almost perfect harmonics in frequencies (No interferences from delayed reflections) , make any music seemlessly glide into the soul, soothing, relaxed, pure, and transporting ! A feeling we discovered only with the Black-Holes treatment.
With those soothing harmonics and the absence of any harshness, ear fatigue is reduced to absolute minimum.
UNBELIEVABLE ? Of course, we know, we coudn' t believe all the benefits when we first heard the prototypes. But it' s all so UNDENIABLY REAL that we can let you audition a pair without paying upfront, risk free. ( see AUDITION page )

Such a pure sound you didn' t know you could hear from your audio & speakers !

All Those sound improvements will surprise and impress you, as they did for us. They' re a great joy to hear and discover; but the almost physical-well-being feelings and profound understanding of the power and beauty of pure, unaltered music, are a little beyond words. So: "The overall soul-soothing harmonies gently make you float on a body-surrounding clear bass cloud ", is an Ok summary, but you will grasp the real feelings ONLY when you HEAR it. The BLACK-HOLES will nicely and greatly upgrade your music so much, that we can send them for you to try, and buy them only if you' re amazed! (see AUDITION)
