Hi! I was looking for a FRFR solution for my Helix floor model, both for acoustic sounds and use of amps with IRs. This would make my FOH signal and amp levels match. Since I already had 2 BOSS Katana 112 mk. 1s, I opted for getting two of these speakers. This is a great affordable solution. I have plenty of power from the Katanas, and a very good portable stereo setup. I'm looking forward to trying it out live, but so far I'm confident that it will work with no issues. The matching of line/amp levels is just so nice. I have a set of Dynaudio LYD48 to do finetuning of presets, and then I double check on the combos, and it's so nice that they match quite close. Highly recommended :-) P.s. I run the amp via return only and skip the preamps, though for acoustic guitar it still works, and great too ;-)
