Sound Dropoff

I recently purchased a L1 M 1s with B2 and tone match, and I have used it for 6 gigs, and my 3 weekly gigs, I notice a signifigant sound drop off after about 10-15 feet away from the L1. Set up in the same spots as I did my compact and the sound carried better from the compact. Could room acoustics have any effect on this? Turning up the volume made no difference. Could it really just be My ear hearing things different with the way this is constructed vs. the L1 Compact?
