I know all the obvious reasons not to use such...still...
Searching for premium audio quality speaker-level toggle switch. DPDT minimum, 4PDT preferred. The applications below may affect your reply.
The toggles will switch polarity on the speaker cable of six speakers crossed above 150 Hz, each powered by 100Wrms @ 8 Ohms, low-current amp.
One sub amp, 1 kW on 4 Ohm load.
TIA!
