Sub Harmonic Bass Synthesizer

I know it's not purest, but I think this would be pretty cool to have for home theater if you had some nice subwoofers.

Basically, it takes the signal and makes it one octave lower. For a bass nut, you could have a pair of subs running regular, and then a pair just used for "impact" ... maybe something DIY tuned really low. Or just anything massive.

Sounds like a really good way to have a bunch of subwoofers exceed their xmax and do a pile of damage. It is subsonic filters that are required, not generating subsonics! Another in a long list of daft pointless products

I had a dBX subharmonic synthesizer with an !8" sealed downfiring subwoofer in the 1980's and I thought it was pretty cool. It would take a bass guitar for example and add its subharmonics so you had deeper bass. I don't recall it going subsonic or infrasonic though and my subwoofer never acted up. It used to rock the house though. I got rid of that equipment when I changed over to surround sound, as there were no tape monitor circuits in which to hook them up. I suppose it could be hooked up in the subwoofer out line like a BFD is hooked up.

Neat!

Yeah, that's how I would imagine connecting one. It would probably be very cool for movies and such. It looks like you can adjust subsonic levels, 24-36Hz and 36Hz-56Hz and then you can cross it over at 80Hz and 120Hz (for the synthesizing, not for you're regular LFE stuff where you'd cross over where ever.

Just thought it was kinda cool.

It was cool because I also had a dBx dynamic range expander and a dBx waveform peak restorer which corrected clipped signals. Those were the components that I couldn't think of how to get them connected without a tape monitor loop. I sold all three of them as a package.
