Seaton Sound Submersive HP+ Master and Slave Combo

Moved to a smaller place and need to let these beauties go. Both subs are in perfect condition as far as I can tell (inspected closely for scratches/dings). Grills also have no pulls and no dust.
Amazing subs, these are components for some of the top professional theater installations and have incredible accuracy and extension.
I have the original boxes and packing material if shipping is necessary, I am the original owner. Would ship in two boxes 29x23x31 inches and 150 lbs each.
Local pickup in the San Francisco bay area is preferred, but I can ship - buyer pays shipping.

"Vintage cherry finish" - may be slightly darker than if you have cherry finish from Seaton.

I will include the speakON cable to connect the Master -- Slave units as well as the RCA coax --> XLR adapter (only use if you can't hook up XLR from your receiver or pre-amp).
