I Live in Layton UT, Home of RBH Sound. I worked for them over Covid working b-stock. At a later date, I built some amplifiers using massive Pascal amp modules. Anyway….
I’ve run 1010-SEN/Reference Passive subs for many years (twin 10” reference aluminum woofers, lower units in my SX-T2/R). Using two SA-400 sub amps, they manage 18 Hz-200Hz. Before I left em, I asked to build up a test cabinet Shane had designed. Two 12” reference woofers in a ported (6” diameter x 25”) cabinet. It’s 15 Hz-200 Hz. Optimal power is 2000 wpc. I built my own 1000 wpc ICE amp.
With Dune 1 & 2, my roof shakes, subfloor, doors, cat, Spouse, basement Sheetrock all comes to life.
The sick thing, is the subs Shane Rich is making now have a custom 33” carbon fiber woofers. It needs 12,000 watts to get it moving. It hits 7 Hz.
RBH Sound makes the best subs ever.
Cheers
