Hi does it possible to use a VS212 with a dsl1H 50th for the Ohms??? Thanks it’s writing 4ohm mono but 8ohm stéréo and on the Head 16 or 8 ohm ..

to the forum. From what I can find, the VS212 is 2 x 8 ohm speakers wired for single 4 ohm input (parallel) or stereo with 2 x 8 ohm input. I'm not sure about the 8 ohm out on the DSL1H 50th. I have a DSL1H, and it's 16 ohm out only. If you rewired the VS212 to series wiring it would be 16 ohm and match the DSL1H, so that's a possible solution.

On dsl1H i have on the same Out 1w @ 16 ohm (8ohm min) on vs212 i have Mono inputs 4 OHM Right Input 8 ohm Left Input 8 Ohm

If the amp is ok with 8 ohm, you could use one of the stereo jacks, but that's just 1 speaker. Easy (no rewiring) solution is a Palmer Cab Merger. Plug into both stereo jacks @ 8 ohm, and use the series jack to amp @ 16 ohm.

Right. So plug amp out into right input jack and use just that speaker only. Or, get that gizmo pictured above. No other way to do it without rewiring the cab,
