Keep in mind that even in very small venues, living room parties, etc..., the best sounds to boost will be the highs and lows. Only a slight boost on the mid range sounds will be needed. Also, remember that most individuals in those facilities have some sort of hearing loss, for men they tend to lose the highs and women, tend to lose the lows, hence the emphasis on those frequencies.

When I performed those very small venues, I still utilized my Bose L1 Compact, but it has no EQ system, therefore, I had to rely on the Keyboard's EQ settings to achieve the best overall sound. Additionally, because I was primarily a vocalist/entertainer, using the onboard speakers would have invited feedback, though not when I used my Crown CM-311A headset mic. It was incredible and never experienced any feedback at all, even with the onboard sound system.

Good luck,

Gary
