"Gargoyle, YMMV, but I
associate LF propagation/amplification with mass; there has to be some
way to really "anchor" at least the LF driver. "Noted"I was thinking MF for
the felt and/or paper horns, although I guess you could begin with a
chi...

Yes, although the typical cork sheets might be too smooth and hard to apply. However if you were to crush the cork into granules... then apply to the horn, that should be feasible. Can you tell us anything about the picture you just posted? It doesn'...

[quote user="Paul S"]You might also want to try stiffened felt, which seemed to work "as well" as the paper for me, and it is easier to form. Just saturate the pre-shaped felt with runny "paste", whether gluten/starch or methyl cellulose, milk glue...

I tried to do a google image search, but nothing appeared, maybe Romy will share.I got to pondering what benefit having the surface textured may have. It seems the texture of sharkskin for example can reduce the surface suction.From the interweb:"A s...

[quote user="Paul S"]My results so far agree with Romy's theory, that the paper horns begin to eat energy when I used them "too low". In this case I used 4-600 Hz with 6 dB roll-off.[/quote]Thanks, this gives me somewhere to start. I am considering ...

Two things I see with that horn. The ribs will have an effect on dispersing internal reflections, positively I'm assuming.The second thing, the ribs are causing a fairly substantial increase in surface area inside the cone, it has the surface area of...

What are some of the limitations to using such a light-weight composition? (frequency, resonance etc.)I must admit the construction technique is appealing albeit somewhat slow. It lends itself to experimentation. Perhaps rather then using traditional...

[quote user="Romy the Cat"]So, Gargoyle, from what you
says this concept of “acoustic watt” is used to predict the necessary power/gain
of amplification needed for a drive an acoustic system in a given room. I feel
that the acoustic wattage is ver...

[quote user="Romy"] My question is: why in this picture the concept
of Acoustic Power or Acoustical Watt can advance anything? I am not being sarcastic,
I just truly do not know where to use it.
[/quote]Sorry, I'm not trying to answer for Scott, b...

The "sound power" for a rock concert is 0.1W (~110db), lower then the 1W (120db) cited for Symphony orchestras.If ones goal is to "reproduce" symphony in all it's glory, one should aim for 1 acoustical watt at the listening position, or at least as ...

[quote user="Romy the Cat"] Scott L wrote: the last time I checked, you were using 6each
@ 10 inch low frequency drivers per side. That's "getting there" but
still not enough to produce an acoustical watt. (which horns CAN do).
I am not sure w...

I figured because I am going to be leaching information off here in my future horn endeavors, I thought I would share where I have been.If you are going to run bare duplexes, you may consider something like these. IMO the pinnacle of duplex enclosure...

[quote user="Romy the Cat"]Interesting that with audio we can re-tune A lower by
running ....blah blah blah[/quote]Is it interesting?...

Not that I want to divert my attention from my horn project, I'll admit I am curious. The horns are going to take some time, so I might be able to squeeze this in if it proves feasible.While some might scoff at such a thought, for many of us, digital...

This will be yet another log on building a maconalds inspired speaker conglomerates.So far what I gather is I need to first sort out a upperbass/mid frequency combination before I dive into the rest of the details.I too, will try to provide pretty sk...

It might be useful in some other applications. ...

Stereo bass is where it's at....

I hate it when people poke at speakers with their fingers....

Nice setup.Can you describe the active setup you are using?...
