I remember seeing such for sale at the old 60 Brady St Alembic location in San Francisco during  the 1970s
This price is a bargain !

Local pick-up in New York only.   
Does it come with the forklift so you can move it?

Bill, tgo

The price reflects the need to hire someone to move the cabinets each time you want to use them.

These B-15 units are indeed massive. I have two matching A-15 units that I purchased in the early 1970s. In past times I actually gigged with them on a weekly basis . In the 1970s I was able to fit them both in a VW BUG with the rear seat removed . I powered that bass rig with a SUNN 2000S and a Fender Dual Showman . I was a tad stronger in those days . I still have those speakers that currently reside in my basement studio ,and have them connected to a Bi amplified sound system . I am powering them with a Yamaha P 2200 power amplifier crossed over at 500 HZ with a Crown VFX2A active cross over  .The top end are two Cerwin Vega 211R's and and two EV mid-range horns horn powered by an AB Systems series 200.

Forklift.

hehehehe

Bill, tgo

Keep in mind - speakers not included. So at least it's lighter.
