Home Speaker Asylum

General speaker questions for audio and home theater.

RE: That is a very menacing object in that photo

I know what you mean AND the motor assembly was so impressive that although it was cheap, i passed on it. It was VERY heavy for it's size and it was big, that's also on a reinforced pallet. It has a water cooled field magnet as well as water cooled VC.

If you zoom in, you can see it's rating and if attached to a radiator, it can reproduce music or anything else in that frequency range.

I was at a vibration tests a couple times at Wyle labs where a bigger brother to this one was used to vibrate a Sounding rocket payloads.

That was driven by the biggest amplifier i have ever seen, a 250KW tube amplifier also made by Ling that took up the entire wall of the room floor to ceiling, literally like a huge radio transmitter. It had two giant glowing red output triodes and two BIG driver tubes.. One of the operators saw i was interested and showed me some of it, I was speechless looking at the proportions of all the bits.

The operator told of one year they made up and 8 foot square thick plywood piston and attached it and rolled the assembly on the rail tracks to the open garage door and played Christmas music to Huntsville / Marshal / Redstone.

He said it sounded good but was "kinda loud inside", yeah inside the cabinet you mean.
BTW, loudspeaker building advice, if you ever make a large loudspeaker, never let yourself be closed inside one because your curious what it sounds like no matter how your friend says he will let you out right away.
