Romy, are you going to verify the decision of using fragile vintage drivers?E.g. by trying JBL midbass drivers?They would be closer to the design philosophy of the Fane Studio 8M.http://www.jblpro.com/components/maxout.htm#2020H...

I wonder whether an Altec 416 in a sealed enclosure plus transconductance amplifier would be the better solution for most people/circumstances....

Congratulations first for your success with your bass horns, Romy, but have you given away the best position for the lowest channel? Is the wall to the attic where in fact two large IB woofers like the Fostex FW800 or the 24" Hartley-Luth should sit?...

[quote user="Romy the Cat"]1) The foams from back chamber pushed itself through the window of basket and touched the driver cone. Sonically it is very likely but knowing HOW I did the thing I think (hope) it did not happen. Also, both horns hav...
|
|
Romy, I think you have neither a system with back chamber now (because the foam is closed pore), nor a "true compression driver" (because the foam is not rigid). Probably you mainly have a second vibrating system coupled to the cone that enhances mec...

Romy,I hope this is not too much of a threadjacking, but I think the question is connected to yours:Is "little girl" so popular among the owners of expensive hifi because well-earning and hard-working people prefer relaxing music in the evening or is...

[quote user="Romy the Cat"]My carpenter proposes silicon but it not good for painting. Is anybody have any interesting idea how to separate horn and drywall? [/quote]There is acrylate paste that is quite similar to silicon, but can be overpainted....

Better available in the US:http://www.eighteensound.it/index.aspx?mainMenu=view_product&pid=290...

Maybe Ciare's car hifi "kickbass" drivers are an option. They have cloth surround and Bl^2/Re is higher than that of their pro brothers.http://www.ciare.com/pdf/catalogo/CW255.PDFhttp://www.ciare.com/pdf/catalogo/CM205NDA.PDF...

I see no problem beside the price.Melamine stays white over decades and there is no smell at all, at least with the original Basotect I use.http://www.soundprooffoam.com/melamine_foam.html...

Replace the windows with acrylate glass?...

There is nothing hairy and transparent. What about thick soft-PVC?...

I doubt there will be the orchestra in a laptop in 2025. But what if you take existing recordings and so some variations with Melodyne?Watch some Youtube demos of Melodyne DNA / Melodyne Editor, could be a nice toy for you....

A different option for an experiment with something stiffer than paper could be this:http://www.accuton.de/drivers/detail.php?driver=11&matID=4&appID=2I wonder why Accuton have switched to such monstrous motors....

Non strictly on topic, but if someone wants to try two-channel quadrophonia:Free demos available at http://www.andreavonsalis.comSpeakers have to stand 4x90°. Rear speakers stand in the same distance as the front speakers and get the same signal. Bal...

About the bass, which must be lacking in such a construction:I once made an experiment with something similar (single "cut" horn with "mouth" directly adjacent to the driver), and subjectively there was much less bass extension when I placed a barrie...

Zako, Ambiophonics is wonderful but unfortunately the Ambiophonic decoding is not compatible with stereo recordings.[/quote]Romy, are you sure you don't mix it up with Ambisonics? Ambiophonics is for stereo....

Romy,what I have been wondering for a while, why don't you run your S2 from 500 Hz to 5000 Hz?...

[quote user="Romy the Cat"]Now, a few predictions. Next year, if the Silbatone folks are no fool. then will discard the stupid Aporia and will come up with a new loudspeaker.

[quote user="Joe Roberts"]At Munich, we cranked the Aporias up with a 20w 845 SE and they did not catch on fire but our goal for the speaker is "big horn sound in normal sized rooms"--and 8W will do that.[/quote]The Manger catches on fire with some m...

In principle a higher air gap for more linear excursion goes hand in hand with lower flux density (weaker motor) for a high-Qts driver when the amount of magnetic material is fixed. No market, however....
