Whats everybody working at???

[Magura]

What are you all working at at the moment, it would give a little background info about the respective threads/- postings + funny to know how many are actually building something.

Hmm, better set an example

Im working on a Son Of Zen, + and experiment about full RGB LED's and ambient light cancellation.

i'm working on:

my pair of aleph 2's

battery powered BOSOZ

3-channel gainclone (still tweaking)

secret heatsink project

 

[ddog]

I'm workinkg on SMPS to car amp, amp will be 2chan LM3886 50W

 

[SY]

Just finished my new preamp to replace the old reliable one that is no longer reliable.

Now I can continue trying to raise funds to finish my direct-drive ESL amp. If I can only sell these output transformers....

 

[elizard]

Saving money for a valve buffered IGC, and a p3a.

On the drawing board (my head) there is a preamp, aleph 5, 5-6 channel pre+power amp .. and several other things (BUT money!)

oh yeah, forgot, and a pair of voigt pipes

 

[SkinnyBoy]

8 channel amp based on the LM4780 ICs, but I am begining to think I should have gotten bigger toroidals, even though I haven't made anything yet.. lol

My towers still aren't finished... I kinda work in stages... work on something for a few months, then find something else....

I also have half a car amp... one day, maybe, it will be useable.. lol

SY, do you have both ESL and cone dipoles. Or have you listened to the two types enough to have an opinion you'd be willing to express.

Or is that another thread? What to do?

[PassFan]

I am building a SE 2A3

a PP EL84

A pair of monoblock SOZ's/powered off car batteries.

Rebuilding the chassis for my BOSOZ

Two country style wall shelves ( one for wife and one for mom)

Built in cases for my daughters room in an African Motif

Whew... I need a vacation.

 

[SY]

No, my cone speakers are plain old front-firing. The ESLs are the only bipolars I have. Line sources, at that.

 

[roddyama]

Building a passive x-over to add a JBL 077 to my speakers, and adding (trying to) an older Wadia DAC to my cheapo DVD player (first attempt failed).

 

[AudioFreak]

hmm....

Everyone already knows what I'm working on. Audio Related hmm? Yes I think so .

Oh Building things! Sorry, I'm working on a analog meter power monitor and power switcher. But it's sporadic. Porjectus interruptus. At the rate assembling a working audio system is going it may be spring. I fried the woofers in one of my Prodigies last night. So fixing that is the project first at hand. This evening I've been searching the archives and catalogs thinking of doing a dipole line array.

dipole line array

That's exactly what I've been wanting to do to take the midbass load off of my ESLs. I'm envisioning a stack of 15 or 16 drivers in the 4 or 5 inch range to run from about 70 Hz up to 300-400. All integrated into a nice column that contains the ESLs.

Have you checked out these little 3" Aurasound drivers?

Uh...nothing audio at the moment... I got hotter things frying...

SY: Are you speaking of your Acoustats and if so what size are they. Mine were 2+2, I think. Two tall, two wide. They were and loud and clean but I XOvered at 225 Hz. Did not image to my liking at all though.

I sit as close to the orchestra as I can. I like big music big. So I'm toying with the idea of selling the Prodigies and building a "full range dipolar line array." Would sure like to hear one first. I like my chamber music as exquisitely clean as it is through my ESLs.

[Circlotron]

Over the last day or so I built a 5 opamp cct that is 600Hz lpf -> full wave rect -> 1Hz lpf so I can use my multimeter on 2v DC range to measure AC millivolts. Playing around a lot measuring Thiele/Small parameters on cheap, crummy speakers.

As always, things that look simple are not.

These are Acoustat stators set up in a 1+1 array. I've changed the diaphragms and coatings, changed the interface to a single transformer and passive line-level EQ, and built a frame with "wings" to get some free midbass extension.

NS3-193-8A

Nice specs, the Q in the right range, but since I need 32 of them, they're priced higher than I was looking for. I don't really need good midrange performance since they're getting chopped off pretty steeply at 300 Hz or so.
