Yes – the Laney LA-STUDIO would work fine with an LFR-212. You would connect the XLR out of the LA-STUDIO to the in on the LFR-112 and LFR-212. Set the LFR-112/212 to FRFR mode and you would hear the different cabinet characteristics of the LA-STUDIO’s torpedo setup as you flicked through them. Don’t set the powdered speaker to off – the level coming out of the LA-STUDIO via the XLR output is a line-level signal and requires amplifying. Do not connect the speaker out to the LFR-112/212. That will not work!
