Anyone tried replacing their Heritage acoustic treatment with Baseline material?

[No Disc]

I'm curious if anyone has replaced their stock Heritage acoustic material with something like whats offered by basslinear?

1" thick foam is NOT going to absorb any appreciable LF energy, contrary to claims (even IF it is convoluted like egg cartons [] ).

Don't waste your time or money.

Product Overview

BassLine is an acoustics product applied to the inside of ANY
speaker cabinet to improve bass performance.



Each panel is 12''x 6'' x 1''.

Anyone care to calculate the 1/4 wave frequency of a maximum 45 degree incident thickness of 1.414"????[]

Based upon their dimensions, the best case low frequency effectiveness ends at 2387 Hz! Lots of significant subsonic energy there![:S] ...Gives a new meaning to LF doesn't it!



When BassLine is installed in a speaker cabinet it changes the
acoustical atmosphere conducive to capturing the sound produced by the



back-wave,
from the bass driver.

What Results Can I Expect?

This product produces three-fold results:

1. 
   
   The application of this product to the speaker cabinet walls lowers
   their resonate frequency and reduces sound wave travel through the
   walls of the speaker cabinet. Some estimates suggest that up to
   
   
   30%
   of total sound emanating from a speaker system is through the walls
   of the enclosure. This must be due to their significant mass!!![]
   
   
   
   
2. 
   
   The insulation works to improve the overall performance of the speaker,
   by reducing the effects of
   
   standing waves inside the cabinet - thereby diffusing them as
   opposed to just absorbing them. Since BassLine SpeakerPanels
   are made of wood (so are egg cartons!!!), they absorb a large quantity of the sound
   created by the back-wave, eliminating standing waves. The remaining
   clean sound exits the cabinet, resulting in a an increase in efficiency
   compared to fiberglass or other materials. The force of the back-wave
   (usually
   
   
   tuned
   by the
   
   
   port
   to a frequency lower than that produced by the
   
   
   front-wave)
   is allowed to join the force of the front-wave without some of the
   
   
   
   degrading artifacts.
   
   
   
   
3. 
   
   The integration of front-wave energy added to the back-wave enhanced
   by BassLine and the cabinet itself creates
   
   
   harmonic resonance
   adding color to the lower
   
   
   midrange.
   This re-creates vocals with feeling while achieving VERY clean bass. Sort of like a sonic 'group hug'.
   

The
BassLine SpeakerPanels application can achieve sound well beyond
the limits of audibility into the range of pure

subsonic energy

that moves the body and stirs the soul... A sound long sought after
by audiophiles and discriminating music listeners. Fascinating!!! And even I can agree that the benefits extend "well beyond
the limits of audibility". I fancy that dogs can't hear them either!

The bottom line is that BassLine SpeakerPanels are effective,
inexpensive and simple to apply; resulting in an improved efficiency
and tighter


low end.

Q
Is BassLine egg cartons?



A.
No but the shape of our product is the same. This shape absorbs


50%
of the sound. Fascinating!!! And utter nonsense!

...But then, I may be overlooking something, as it may be that they require the symbiotic use of cable tiptoes to keep the interconnects off of the ground to really make them effective. At least this explanation would make sense! []

And I even resisted making a comment about sonic 'buns of steel' in regards to the "tighter low end" claim...oops!

Where else but in audio and in the new age vitamin market can people actually profit with such nonsense?

They must have an RF circuits engineer designing these products []

So,... is there something that would work?

[DrWho]

The very insulation they advertised removing?

What Mike said...

This is a solution in search of a problem.

Internal cabinet reflections are well understood. The best solution would be a properly designed enclosure. But, as this approach seems to confuse many designers, reactive fill has been used with great effectiveness for a long time. [] You are reaching the proverbial point of greatly diminishing returns.
