Sunny, the GNS MS01 speakers go down to 40 Hz. That frequency is the same as the open E string an a bass guitar. Hence, why you're hearing nice warm bass from the GNS MS01 speakers. If you want the same from performance speakers, you have two options:
1) Buy full range speakers. You need 12 inch or 15 inch bass drivers for an audience that size. Most performance speakers cut off at 55 Hz or even higher. The bass is there but not very deep.
2) Buy a full range speaker that goes as low as 55 Hz to 65 Hz, and budget for a subwoofer. I use two Bose L1 Compacts and a home made 15 inch subwoofer with a 600 watt capability, driven by a Yamaha PX3 power amp. The largest audience I've played for with that system was about 250.
You'll need to buy two speakers so that your output is in stereo. The Genos sounds alright in mono but you miss most of the nuances and detail. Remember that after you make your speaker choice, you need to EQ your Genos so that you get the most out of the chosen speakers. Fortunately, Yamaha provides some pretty good presets in the Master section of the Mixer.
When you move up to larger public venues, you're in an entirely different ball game than simply playing in your living room under perfect and controlled conditions. In fact, you're wise to accept the fact that you'll never match the sound of your GNS MS01 speakers. You're only setting yourself up for disappointment.
You can buy the best of the best speakers but when you're playing live, most of the time you have no control over where you can set up and your speaker placement. Think about it. When you play at home, the speakers, which are specifically designed for the Genos, are aimed right at you. You are the audience as well as, the player. When playing live, you are just the player and what you hear is about 50% of the quality you get at home, if you're lucky. Then there’s room echo and the general noise of the room.
You’re jumping into the deep end of the pool my friend, but I admire your wishes to move into that realm. It will make you a better player. Just don’t expect miracles when it comes to your sound. Stay well.
