Re: Infocomm??? I built a new 18" long excursion Dual-VC speaker for McCauley last year, 1.6" Winding, 0.3" top-plate. These were the unprocessed results from a good ole' front loaded double 18" cabinet 2.0V @ 1m. I was actually really surprised how easy it was to build a speaker which...

Check out this stellar find on eBay, perfect for 1000 seat venues ;-) http://www.ebay.com/itm/Califone-PA919SD-PA919PS-Portable-PA-System-In-Boxes-EXCELLENT-CONDITION-WORKS-/281713881295?pt=LH_DefaultDomain_0&hash=item419774b0cf Edit: Well, I thought this was just a funny eBay thing. I am...

With the nice weather here in Puyallup, we started construction on a new loudspeaker measurement array. THEN in typical fashion, the rain started ! Since there is no easy access to quick spherical measurements around here, we have always wanted build a nice array our selves. Years ago we...

I just thought this was pretty funny, since the computers I grew up with, well... And it was the first time I've seen 32 cores in Task Manager. And the amount of RAM windows is using at idle is more than the total amount my $3000 computer had 5 years ago.

This was posted on comp.dsp by the author. It is a pretty interesting introduction to Digital Signal Processing with lots of neat visualizations. http://jackschaedler.github.io/circles-sines-signals/index.html Mark

I am having trouble finding a good quality rack for some equipment and I am looking for suggestions. The components I have are 19" in depth and I'd like to find a 8U rack which is only 19-20" deep but has covers which are 2-4" deep. I have a number of Hardig Pelican ones, but they are just TOO...

A few years ago I started the project of turning the long abandoned 1970s McCauley Sound factory back into a functional loudspeaker workshop. I think I posted some pictures of the place at the time. The roof leaked everywhere. It was stacked floor to ceiling with enclosure prototypes, lawn...

Tom McCauley and myself attempted to empirically test laminar flow of air through subwoofer port with chicken feathers. Yes, this sounds like a great idea. https://www.youtube.com/watch?v=y1PDUYnZGsk

For some reason I just really want to buy this to play with. http://www.ebay.com/itm/Terabeam-Meade-ETX-125-Maksutov-Cassegrain-OTA-Awesome-Fork-Mount-/161544819037?pt=LH_DefaultDomain_0&hash=item259cd2515d

http://users.ece.utexas.edu/~bevans/courses/rtdsp/index.html Great lecturer. Much better than the MIT course in signals and systems which was out a few years ago. At least as far as practical aspects. Mark

Re: How will removing Ferrofluid from a Celestion CDX14-3050 affect it's response? Some quick measurements if you need them. I did nothing but open a fresh driver and measure on the plane wave tube with and without the Ferro-fluid. This one looks a little funky to begin with. A lot of...

I put this on AV install nightmares on facebook also. We rented a venue to host some slide shows for our Pacific NW camera clubs. See attached photo for the mains left/right setup we got. No HF, No LF. It was pretty bad. I felt sorry for the presenters. Yikes.

I'd love to find the original artist. I can't read it in this copy.

I saw this on comp.dsp. I don't have a smartphone to try it with, but it might be interesting. "Our Java, Android and iOS software development lab at the ASU SenSIP center and NCSS I/UCRC released the award winning Android JDSP (AJDSP). This is a mobile tool for signal processing simulations...

As I browse eBay, I keep seeing these "SPL Sensors" listed from all sorts of different companies obviously catering to the car audio market. I was just wondering what they were? Their websites are all pretty funny. Especially the one which claims 2Hz-20kHz, 50-186+ dBSPL, NIST certified...
