Yamaha HS5i WH Active Studio Monitor, White (Single Unit)
I bought a pair of these to go with my Yamaha CP88 piano.
Are they good monitors? - yes, very!!! loads of detail across all ranges.
Are they a good match for a stage piano? - yes, and so much better than pianos with built-in speakers.
Is there enough bass? - Yes (perhaps suprisingly. There's no need for a subwoofer unless you have a need for excess)
DO they look ok? The white finish of the cabinets and drivers is stunning! So much nicer than boring old black.
Would I recommend them? - yes, without any hesitation.
