Yamaha YSP-1400 Sound bar trialled with synthesizers as if it was a pair of studio monitors

"Why not try a soundbar with my synths in the studio?" I thought to myself. "In theory a soundbar with decent bass has everything you need, and the long flat shape might fit on the shelves a bit better."
And if you don't need masses of volume, the Yamaha YSP-1400 might just tick all your boxes.
