Rotary Subwoofer...not a leslie..low f guys check this tech

Do you really want to set that up every gig?

 

that's been a thing for a while now

 

would that be the best rotary subwoofer for metal?

 

All the stuff you hear on the video is distortion, which makes it not a very good woofer for sound reproduction, since its producing a load of its own sound. Being ducted and a bunch of aerodynamic tricks would help.

 

It's an old unsuccessfull subwoofer project for Home Theaters.

 

What's all this recent interest for these infrasonic devices? Home theater is one thing, IE movies like Earthquake, any disaster movie, etc., but when you get that low, it is not musical sounding at all. If kept up for any length of time at stage volumes, it can be uncomfortable to the point of nausea.

 

So, it IS the best rotary subwoofer for metal! (grin)

 

i'm absolutely astounded at the level and quality of LFE produced by Bob Carver's smallest Sunfire:

i've NO affiliation in any way, just sharing info.

 

I have a Sunfire Jr. and it is just amazing. 11 inches cubed, and sounds like one of those ridiculous Honda's with Type R stickers all over it. Boooooming!

 

I've often wondered about the possibility of making a highly directional subwoofer array using this technology.

 

Wow, I'm really impressed by my headphones.

Didn't know they could go that low, thanks for the chance to put 'em through their paces.

 

Yeah! But just wait a week or two till the linkage gets a bit loose in the joints, if you want to know all about self noise in a sub woofer system.:-(

 

any of you guys know anything about the motorized cone speakers that that Billy Sheehan used to use some years ago? I think they were 18's but not positive

 

Servo drive jobs. He probably realised that stuff is the FoH's job. The coil and magnet on a standard speaker is the motor, servo is just a different way to do it that isn't very good, probably more power pre dating neo magnet motors.

 

Cool was always curious about them thanks for the reply! and yes now that you mention it I think they were servo driven, I read this in an interview with him a long time ago!

 

I'm not a fan. That design blows. It was an air in judgement. It is sub standard in every way.

(Yes, I realize it's an "err"in judgement. I'm just havina little fun.)

 

I used to play with them, to the point of nausea.....found a new group.
