There were two models with either 500Hz (like mine) or 800Hz which used a smaller compression driver and horn. I've found that the lower the crossover frequency, the better the overall sound quality (with 500Hz minimum). The stock Altec passive crossover networks sounded absolutely awful, and I...

In my post was referring to the 902, which was the evolution of the 802 and had a ferrite magnet. I thought I made the ferrite aspect clear (please re-read my sentence). In any event, the harsh quality of the tangerine phase plug has nothing to do with the type of magnet used. Altec Lansing...

Couldn't have said it better myself! :banana-rock:

A 100W load resistor should get warm to the touch when it is dissipating around 25 W or so, and should only get really hot when its getting toward 75-100 watts if it is not attached to a heatsink. My guess is that you amplifier is oscillating at some frequency (assuming you're not feeding a...

From the photo, you have everything wired correctly. I would stick with the value of resistor you have now. The load should not (cannot) cause the amp to smoke if its truly an 8 ohm resistor, and you don't have the speaker load connected to the amp output too. Something else is wrong. The amp...

From my experience, the 811 would indeed be more suited to a very small room, however the VOTT was designed for screening room sized theaters. My A7-500s work well in my 30' long room, however I wouldn't have turned down a room which was 10 feet longer. The biggest issue I've found is that of a...

The Klipsch system is obviously designed for large movie theater sized rooms, and the sound from the drivers will blend well in that environment. The Altec VOTT on the other hand was designed for small theaters and more specifically screening rooms which are typically less than 50 feet in...

Actually, the horn system is way over sized acoustically for the apparent size of the room they are in. Bigger is not necessarily better in all situations.

Actually, basic passive crossovers are extremely easy to "design". A basic two way 2 pole crossover consists of two inductors and two capacitors for each driver wired in a very, very simple circuit. The formulas and schematic diagrams are probably all over the web. Tweaking the basic circuit is...

I'm sure Flint will chime in on this, but I wouldn't even for one second consider large full range speaker. Full range speakers have a small following, but they are by no means a mainstream alternative. The tradeoffs are simply too much; high frequency beaming, super-lightweight cone which is...

I can't speak for the guy "who builds fixes any audio products", but up until a couple years ago I was a electronics engineer at ATI. They are solid and well built products, and most people would find them terrific. I have some issues with some of the more esoteric elements of their design...

Actually, wire gauge has nothing to do with how well a cable deals with a ground loop; in fact, a cable of any gauge is not going to stop a ground loop if there is the potential for one. Either there is a ground loop or there isn't; a ground loop is current flowing through the shield of a cable...

That pretty much has been my experience after I trashed the satellite dish more than a decade ago. Good riddance. We have a hi def TV that was given to me by my employer and is connected to an attic antenna, but it literally hasn't been on for several months now. Peace and quiet......

Ah yes....I remember when I had the wherewithal to write such long posts, complete with pictures. Now I'm more inclined to just tell people to Google the damn thing..... :obscene-birdiedoublered:

No problem with that...please do.

Actually this topic came up a few weeks ago, and I didn't have any of the original pictures and text. Thanks for posting it!

The only real way to go about it is using non-Edison type bulbs. I use mini flood lights around the perimeter of my room, and halogen in the ceiling. Triac dimmers are always iffy since they operate on PWM principles which create basically pulse-type waves with very steep transitions; a sure...

Most older cinemas have been torn down since its not financially practical to be showing "only" one movie at a time. Newer theaters use either JBL or Klipsch. Altec Lansing left the cinema speaker market decades ago, unfortunately.

Soft clipping circuits that I know of work essentially as a peak limiter which lowers the signal level when a certain voltage is exceeded within the circuit. Being a limiter (a limiter is simply a fast compressor with a sharper slope), it will destroy some of the dynamics of your music if you're...

Oh yeah, those old systems had a sense of scale in spades, but their other qualities (frequency response for one) were quite limited. I've been quite lucky that I experienced these systems first hand, and worked at Altec Lansing (in Anaheim, CA) as an electronics engineer just before they went...
