Acoustic bassline refinement

BassLine will absorb enough of the sound to eliminate standing wave distortion but yet allows a larger portion of the sound to escape through the ports without the distortion factor caused by using other insulation products.

What is that supposed to mean?

They seem to fail to provide physical evidence or a thorough explanation on why this product is indeed so special.

Facts:
_____

#1. It will not eliminate the problem of standing waves in a cabinet, no cabinet damping can, thats completely illogical. In the typical enclosure of modern speakers, standing waves are only a real concern at much higher frequencies, well above the extension of the port. And like they mention, the material is not as effective as others when it comes to damping so when these higher frequencies are of a concern, that stuff will not be very sufficient.

#2. It's far too thin to have any significant effect on particularly deep bass frequencies and limited effect on upper bass frequencies as far as internal damping goes. If it was this effective, it would entirely defy the point of the port.

#3. They mention these 'alternatives' absorb too much sound resulting in muffled sound. My question is, how the hell would sound attenuation in itself distort the port output?

Also note midband attentuation can cause a defect in the intended frequency response of the system. In otherwords it's quite probable it will make the speaker sound worse due to a lack of sound reinforcement in the cabinet.

And if that's not enough, it will take up volume inside the cabinet, again altering the intended characteristics.

I should also mention that this stuff (whatever use it has) will have the most effect on systems that have drivers with high volume of air to suspension compliance (old speakers) or modern high efficiency speakers, possibly with a high tuning frequency. Often identified by large enclosures.

The last thing you would want to do is put this stuff in a studio monitor. I don't know if this is what you're planning to do, but anyways... Don't expect this stuff to work like advertised, thats silly, it's nothing more than typical damping material, if not less.

If there is in fact some magical property to this 'dark matter' I am not aware of, it would certainly help if they provided real documentation rather than cheap marketing gimmicks.

My opinion is it's just more of the horse [censored] I see on a regular basis. I don't see at least one reason that would lead me to reconsider my opinion.
 
Just another device designed to empty your pockets!
 
Thanks for your opinion on this stuff NuTT.

I heard about this stuff on another bass bbs were some bass player stuffed this crap in his cabinet. Its a more modern ported cab and say this crap tightend up the low end and improved the midrange. He swears by it. If i were to actually try this crap out it would be on my bass cab.
 
Ah, I assumed you were referring to speaker enclosures. Well thats an entirely different matter. I wouldn't say it would necessarily make it sound better, just different.

Standing waves, reflections and potential resonances unlike in a speaker enclosure, aren't necessarily a bad thing for bass or ported string enclosures altogether.

I wouldn't say this stuff is any better than the traditional fiberglass and such, it really depends on what you're trying to achieve. If it's dirt cheap it wouldn't hurt to try.
