imo, though the Logitech deliver impressive bass, it's satellite speakers lack adequate mid-range presence, particularly important for vocals, and the reason I returned the Logitech system when I initially purchased it for my Tyros1 keyboard. The Yamaha TRS-MS02 system, on the other hand provides both adequate bass & better mid range response, but more importantly, able to mount directly atop Tyros2 and conveniently plug directly into the back of Tyros2, eliminating extraneous wiring & satellite speaker mounting/placement that the Logitech system requires. The problem I find with the TRS-MS02 satellite speakers is that they sound too brash (harsh & grating) and quickly become fatiguing (at least to my ears). The Bose 161's on the other hand deliver vastly improved mid frequencies & much smoother frequency response to boot. This system provides the 'best sounding' portable quick & EZ setup sound system for Tyros2 in my opinion suitable for small venues. - Scott
