Absolutely! Our amps have two speaker outputs so you can build your own modular system.
Plug one into the "bottom" speaker jack and one into the top.
Note: On our amps, the "4 Ohm" jack has a special contact that increases the amplifier's output. This allows you to get additional headroom. It is advised to only plug in a single 4 ohm cabinet/speaker in this jack. Plugging a single 8 ohm cabinet/speaker into the 4 ohm jack will cause the output power to double and put strain on the amp. An 8 ohm cabinet/speaker should only be plugged into the 4 ohm jack if there is an additional 8 ohm cabinet/speaker in the 8 ohm jack.
