Speaker system

A large 1980's vintage boom box...

A butler to crank it would be an extra expense.

For such a large space (hospitality?) and the stated budget you will most likely be better off to start with a Public Address (PA) system.

If you have a "Guitar Center" nearby you could consult them (they carry self powered Bluetooth speakers).

If no "GC" then look for a local pro-sound company.

You would be better served looking at a pro audio site.

i.e.Yamaha or QSC powered speakers with 15inch woofers and possibly a sub.

Altec Lansing VOT solid state amp and solid state preamp.

You may want to divide the room if possible. I doubt if you will be experiencing any type of sound stage. That may not be that important.

BTW I have Yamaha DSR 15's ,2 FOCAL CMS subs that I am controlling with a Benchmark DAC 3 HGC ,OPPO CD player and Cambridge sound streamer.......Sounds great outside for party's or large indoor rooms ...I am not saying this is to die for. It sounds a lot better than you would expect of a PA system.

Good Luck

@torquerulesok ...or send him out to the wet skid pad with some vague directions on parking brake application vs. quick twists of the steering.

901s' could certainly 'fill' the ops' space...2 pairs hooked up to a K-watt pro amp driven by a simple pre with a cell for source...

Back when, a salesclone admitted they'd driven a pair of 901s' with a kilowatt amp and the little suckers acted like they wanted More....never tried that with mine... ;)
