Re: Powered Speaker suggestion for Roland SPD-SX
It depends on your budget. I have owned the Rokit 5's, which are OK and cheap ($200 used easily). They are not "accurate" or "flat" in the sense Yamaha monitors are, and have a"bump" in the midrange, with less than stellar highs.
I also have the Yamaha HS80M monitors ($450 used) hooked up to my TV for home theatre and music, and they are great, with 8" drivers. They rival hard-core audiophile gear, (which I have also owned). Their little brothers, the HS50M are generally about $300 used.
