I would say Harley did not waste any time.

it was time well spent

just my 2¢

Almost embarrassed to associate myself with this hobby.

Then don't. Commercial loudspeaker manufacturing isn't a hobby.

talking about the broad user base of audio equipment in general who fall for BS on the daily. I do a lot to not associate myself with most people involved in it. Honestly just sad that adults fall for a speaker like this.

Would another plus (to the sibleius / voight) is with so much coming out of the port exit, less floor bounce from the driver compared to a mltl ?

Hi Norman!
Currently listening to my folded Voigt Pipes, very similar to the Sibelius except I use 10 inch Field core drivers , so much larger boxes.
I just had a listen to the port/ opening and I reckon about 50% of the sound comes from the port.
These boxes sound better on stands about 50mm from the floor ( the stands take the “ blur” out of the bass.
I have a Wooden floor, so I don’t want the floor being excited by the bass, like a downward facing port would..

yea, post 1063 shows a health response coming out of the port/slot................

In response to a question, here is photo of how I applied the 4 grams of Angel Hair. I wrapped the angel hair in a polyester fleece package, so it stays behind the driver.

 

[LeifB60]

Hello.
How did you come to the conclusion that 4 grams is what suits you best?

 

[Wil_NL]

The Angel Hair provides a more pleasant high. However, this damping material is super effective and already at a few grams you see the low from the bass port decrease. Through measurements determined that 4 grams is acceptable.

Do you have any angel hair down in the front pointy part of the cabinet?

Are they placed on both sides and not on the back?
It seems so in the previous drawing. So 2x4 grams in each speaker?

 

[Wil_NL]

It’s only 4 grams each speaker just behind the driver.

 

[sterlingmck]

Do you have any felt on anywhere on the walls of the cabinet?

Yep. Look at the drawing 😉

I looked at making a little backyard hobby/ business selling my speakers and decided that it wasn’t going to work.
So, good for Harley, for not giving up,!

I've also tried little backyard / garage businesses (not audio) in my life, but could never grow it into a proper business. It seems to always cone down to marketing and I sucked at marketing. Seems like the correct marketing approach or people is what helped Harley and Pearl Acoustics - his daughter in this case.
Anyway - I really like this interview with Harley.

PS: But I think it is a stupid title for this video.

 

[JohnnyDee]

Yes.
I watched that video too, yesterday!
Harley is an interesting man!
He makes great claims about the bass on these speakers… I guess the proof would be in the listening??

I have no doubts the box goes low — ignoring the A12pw, the A10.2 had the lowest bass potential.

How loud or how much air youcan move will depend on the gain the horn brings.
