One or the other, equally, will be the best sound upgrade you ever heard, the best sound-investment, for no pricey audio will ever fix universal reflection big problems. Main differences being room-treatment will soundproof your room a bit, while Black-Holes will give a little better bass definition & loudness. ( If you do both, you won' t believe how crappy your sound was before )
The first tests were made in a room with 7" thick big bass-traps, great sound panels on sides + back + front walls, also on ceiling & ceiling joints and corners, and a thick 12'x12' carpet... The new-found perfect harmonies, and bass punch, audibility, and physically enveloping presence, were "melt in your chair" impressive. Before, we also thought the sound coudn' t get a great amount better, we were wrong.
The laws of physics do not allow for such a possibility, and, it as never happened before, BUT, if for some unusual circomstances you don' t feel the upgrades are worth every penny, PLEASE DO send them back for the total deposit refund, we are proud to offer " Audition before you buy, risk free ", it would make a great example of it. ( see ACOUSTICS )
A sound reflection is an echo. Whenever you hear your echo; the tone of your voice is changed, the echo sounds "funny", and has a boomy resonance. All the reflections (fast echoes) in your room add multiple similar alterations on top of your sound system, you are NOT hearing it as clean and pure as it could sound. ( see ACOUSTICS )
No.The size and shape of their slim but sturdy aluminum is precisely designed to resonate & vibrate using the exact natural properties of the ecological fibreglass used, which also strongly maintains the resonators at their most effective positions and alignment, in a 4 parts mechanism that can withstand the worst shipping conditions or fall.
Comb Filtering caused by Sound Reflections: As reflected sounds travel a further distance than the direct sound, they arrive at our ears or at a microphone later. Both signals are identical, but one signal is delayed by a few milliseconds, causing a comb filter, where some frequencies are cancelled and some are summed.

Soundexman pays about 110 to ship you the Black-Holes, if you would return them after a week or 2 of listening, it would mean a 110 loss, a risk we gladly take, given the great efficiency of our products. If we would also pay the 110 for you to return them, it would be a 220+prep/time loss, which would become unfair. So the shipping-back cost would be on your part, BUT you shouldn' t worry about it since: 1) even if you hear only half of the imrovements described, you' d still gladly buy them, that' s why we have no returns so far... 2) If you invite a few friends to listen to the sound/music refinements, one would surely want to buy them from you..
3) You can e-mail us to ask for a circumstantial shipping-back coverage; we are actually trying to set-up a way for Soundexman to cover both costs if the situation arises.
30 Days is the official Audition Trial period, but about 95% audiophiles decide to keep them the day after or in less than a week, helping us greatly with salaries, material costs, production & delivery speed. So we appreciate the balance as soon as you are convinced. But if some reason makes you need even more than 30 days, simply message us.
Yes, at production & delivery cost, let' s keep such a fine sound-tuning system up and running ! ( It never happened yet, they are sturdy and easy to maintain. )
... is what you' re going to say the first time you hear the difference !
The same Black-Holes fit dozens of different speakers. 3 reasons for a lesser fit :
- If you go from a 3 drivers speaker to 4 or 5 drivers, the pads won' t control the bottom driver.
- The top of the new speaker is not flat, unless you have Warp-10 Black-Holes.
- The new speaker has a much greater width. But in any case, the Black-Holes would still make the sound better, or you can sell them to upgrade to Warp-10, or even send them back to Soundexman for a trade-in upgrade with a small fee depending on timing and model.
The company subcontracts parts and materials from production sites all over America: the fabric is manufactured in Texas, the fiber glass in Indiana or Alabama, the wood mostly in U.S., the aluminum parts in Montreal/Canada ; all for great craftsmanship at low cost, so you can get the best price possible.
But the company' s main coordination site, where most of Soundexman "is" or "appens", is in Phoenix, Arizona, which is also the company' s website physical location. After final assembly and/or inspection, the end-products can be shipped from their last location ; either New-York, Ontario, or Montreal, depending mostly on model, or destination, and/or timing.
Yes, you will be very pleasantly surprised by how much better your sound will get, in a few ways that can only be understood when heard !
It is important for me to express my satisfaction about the Black Holes. I tried to treat the acoustics in many ways in my listening room without optimal results. I thought about upgrading my tower speakers, until I heard about the Black Holes. Since then the bass sounds have a better focus, and the overall definition is clearer. I'm happy with the sound upgrades results, and quite glad to keep my audio system as is. Finally I want to mention the excellent service from Soundexman, they fulfilled my expectations. Thanks again!

The Black holes acoustic treatment design concept is quite interesting. Having spent a bit of time with it, I can say it does affect the soundstage in a significant way. The sound is projected more forward, almost like adding the horn projection to your speakers and there is more space created around the singer. This is the result of testing in a fully treated room, I can only imagine the impact even more significant in a non-treated room.

It was the first time that nothing was wrong or annoying in any song I could listen to. All my life sometimes a high pitch sound or voice would make me lower the volume, or some bass and drums would congest the music and overwhelm my ears... Now I can listen to higher volume and some music or genres I didn' t like now they all sound great ! It is totally true that harmonies unaltered by reflections make the music much better and enjoyable, as much a sound upgrade as my 300-B amp and chord DAC together !

Being a life long audiophile even before I knew what one was. I fell in love with music in my childhood. With my parents vinyl and Marconi tube amp. In my 30's and 40's I have tried to recreate that beautiful sound and have succeeded, and "probably" surpassed it ; Oh how many times I' ve wished to travel back in time just to listen for a few moments, to compare. Now in my 50's , I' ve learned that room treatment is just as important as components if not more. My room is fully treated with bass traps, panels, bookshelves, carpets etc. Audio salesmen always told me you can overdo it, it' s not true, unless all surfaces are completely covered, they will push cables + wires before any type of treatment. I' m a guitar musician with multiple guitars and amps and I experiment all the time, it' s part of the fun. So I tried the Black-Holes and heard positive improvements. These relatively new and innovative panels have helped me finally get the beautiful sound I fell in love with in my childhood, and that' s priceless. A definite upgrade and keeper !

Super efficient fabrication ! The bass frequencies become clearer and more audible, then better support the other instruments. The ''comb filtering'' is considerably reduced within high frequencies, which allows a longer and more enjoyable sound exposure for the more sensitive ears. 5/5 !

All the little details sparkle everywhere around, my soundstage is like panoramic now. And sometimes I get surprised by a sound so real it doesn' t seem to come from the speakers. If you like clarity and separation and you don' t like boomy bass like me, get these black holes you won' t regret it. It' s incredible how frequencies harmonize together and the music is really more natural. Now I understand they say treatment counts as much as equipment.
