I have never been satisfied with powered monitors. I took my helix and guitar to a shop and tried the 12'' variation of just about every make including Yamaha, qsc, electrolux, etc. I own an RCF HD32a which sounded the best to me but was still lacking the tonal qualities I like. Helix in 4 cable to my tube amp never sounded good and straight through the front was the worst. All of these options sounded pretty good with the several boss units I have so I just assumed the helix was not that good. Then I purchased the Powercab 112 plus. The tone and sound dispersion are far better to my ears than the monitors. Not exactly tube amp tone but close when in LF Flat. That mode shuts off the high frequency driver and sounds very amp like. I know it's not just me, everyone I jam with has noticed it as well. I have gotten nothing but praise. The speaker emulations are nice, especially cream and greenback but I prefer LF Flat mode and run IR's or cabs in the helix. I am mostly high gain metal so finding anything as good as a good tube amp just isn't going to happen. The powercab is as close as I have come thus far. It's plenty loud enough and weighs 35 lbs. Other options I have heard are really good are Atomic, Mission Gemini 212 and Xitone but they are more expensive and I have not experienced them personally. Also Laney just released the LFR 112 and Seymour Duncan has the powerstage 170. Hope this helps.
