Wow, you must have a lot of floor space to design something that wide. They look inspired by the Simplex W cabinets...... am I correct?Quote:

Good question.... I assumed they were just stands.Quote:

You've never seen Analog Addict's pictures?Quote:

Not that simple a series of related Qs, so best I can do for now with my time constraints:
Sound propagation is AC, hence the term cycles/sec [cps] or Hertz [Hz], so depending on the phase of the signal it will cause the driver to move either in [rarefaction wave] or out [compression wave]: Some Basic Principles
Bass Reflex Loudspeakers

Nicely done! Did I miss the cubic volume of those boxes? I've found the 604s I have don't sound half bad in the 828s that they came in. And of course, the vent size is about half of what your showing there....
those look awsome cradledorf, i see why the flat black. cool idea for cab design too
Any pics of the cabs with the updated/smaller ports? Kind of hard to get a good look at them in the video......Quote:

This should put tuning around 45-50 Hz, if 7.3 is net and the sloped wall angle doesn't alter it too much.Quote:

Nice build, sounds like schrapnel going through a buzz saw on my lowly computer speakers.
Even worse on mine....... :( I measured them long ago and they just barely do the telephone BW, so no highs, no lows and even worse than B0$3 through the mids. Just a 2" paper 'full-range' driver like is in a small, cheap clock radio.

The GPA crossovers are probably better sounding/cleaner than the (unrestored) originals anyways (new caps, etc.)......Quote:

My computer speakers were built by this company called Altec Lansing. Some of you may have heard of them. I actually feel like a traitor owning and using these but I bought them when I bought my first computer back at the very end of the 90's (yes, I was very late to jump on the computer bandwagon)--many years before I joined this forum. I had no idea back then that they weren't "real" Altecs. Quite the contrary--at the time, I owned a pair of Valencias, a pair of Model 9's, and a pair of A7's and was excited that I could buy brand new Altecs for my first computer. Once I got them home I noticed I could coax some pretty good sound out of them (decent bass, mids, and h.f.--but only if I relied heavily on the graphic equalizer on my PC), but I did notice they sure didn't sound like the Altecs I already owned which didn't need much "help" to sound great! They were inexpensive, powered PC speakers with a decent sized sub-woofer included in the package. They still work like new, so I guess since they're bought and paid for, I'm keeping them.....Quote:

If posting these pics doesn't start a riot, how 'bout this question. Are these the P.C. version of the Voice of the Theater? ;) Probably shouldn't joke because it is sad that this kind of stuff is all that Altec produces today, but sometimes in life if we don't choose to laugh, we'll cry for sure...... :( Not to mention, we have GPA producing brand new "classic" Altec gear and parts, so there is a happy ending to the Altec Lansing story......
Cradeldorf--as far as someone having 604's hooked up to their computer and being able to tell from that Youtube video what your 604's sound like--tell them not even close. The built in mic on your video camera is your real bottleneck. I can hear a huge difference between "soundboard" audio on my PC speakers and something recorded with a built in "condenser" mic on a video camera....... I still enjoy your vids though--gives you a look at some great speakers in action and you can at least kind of hear them.....
