Indeed. All my speakers are 93-96 dB/1 watt/1 meter with an overall 8 ohm impedance so I couldn't justify the 350 watter!
Given that the loudspeaker could physically produce the SPL, at a 10 foot listening distance a single 93 dB speaker could produce ~ 105 dB. A pair of them plus some room gain would get you closer to ~ 110 dB.
I think you're good!
