Sorry Chris! thought you were talking about the power source. The lower RCA is used to connect the internal amp with the other speaker. The two other connectors down the pot knob are the right and left input. There's a typical 9v dc connector placed on one side of the speaker to power the amp which was not shown in the picture. The attached picture shows the dc connector in my karlsonators.

Great work Fran. You may be interested in these Hypercubes - kind of like a sphere in a boxy way - but very good with eliminating internal modes. Here is an example with foam core and a 5in PRV driver.

Plenty of room inside for a class D amp like TPA3116D2.
Glad you think they look interesting. Use thin ply - almost like guitar tone wood spruce tops. Making them out of wood will require nice 60deg beveled edges so they fit smoothly together. The OP on that thread used a Dayton RS100 which seems to have good amount of xmax and measured really flat in this box.
So many nice projects here.
Decided to add a picture of my DIY speakers.
The horns were exclusively build for an Etheraudio fullrange driver.
Hi Alexandro!
Can you tell me what you think about the Etheraudio fullrange driver's sound overall? Have you compared it against other fullrange drivers of similar cost? If so what were the pluses & minuses vs the other fullrange driver(s)?

Hi Makoto!
Tell me what do you think of the sound of those "Nessie" cabinets? I've always been intrigued by their looks, but I've never knew anyone who's even seen a pair, let alone heard them! Do you know where I can obtain the plans?

Hi Zilla!
Thanks for the input about the Tang Band 1808 driver. I've heard nothing but good things about the 1808 and the 1772 drivers. I'd really like to hear a pair of the 1808 or 1772 in my Sachikos someday!
I have a very interesting pair of 5" fullrange drivers. In fact they look similar to ---{but definitely aren't}--- the http://www.diyaudio.com/forums/full-range/130743-rca-5-inch-military-fullrange-drivers.html which can be seen here: RCA MI-2989 fullrange drivers I was wondering if you know of a simple cabinet that I could try for these? I'm not looking for a sealed cabinet, but a Fonken might be worth attempting. Do you have any suggestions Zilla?

Dear Tom,
Thank you for your questions and excuse me for the late response.
Though I am not really very experienced in hi-fi systems listening I had the opportunity (or may be the chance) to participate to more then 3000 classical music concerts all around the world.
From this position, my truth is that the Etheraudio's full range driver sound is closest to the live performances I've heard during all those years.
In this regard I did't have the chance neither to make any special measurement of the driver nor to compare it against other speakers. This driver just sounds right. I believe this is the main role of any driver.
Please have in mind that due to some budget constrains I was unable to purchase a finished product from Etheraudio. I bought only the drivers. The engineers from the company were kind enough to provide me with the building plans of the horns and the project was executed by a close friend of mine who is a carpenter.
In case further information is needed please do not hesitate to ask- will try to obtain as much information as I can.
Kind regards.

I'm sorry in poor English.
Sound of Nessie is ideal.
The sound without a sense of oppression, similar to the rear open box.
In high-speed bass, and bass that shakes the earth.

Hey Charcoal - I really like the look of those Sinido drivers - the 'clean' look of linen coloured paper drivers. What has been your experience with these drivers ?
Well, I tried almost all of them in BLH, TLs, BR, FLH, two ways also.
I think its best value/quality I can have here (live 3-4 hours from Istvan Varga). Extremely pleased.
For major part of speakers I made with them - you can check several albums on my FB page (see below) and my top "costs and wife no object ))" Flag speakers, link is also below.
For the look of diffusor - its specifically milled paper pulp + some wool for damping.

An externally hosted image should be here but it was not working when we last tested it.
