Hello! I see a lot of people asking about mixing a 410 with a 115, and getting a lot of bad answers saying about phase issues and a 410 being able to push more air than a 115 whilst also being more defined. That being said, what about pairing a 410 with a 118? One of my favourite players (Mike Inez) on stage uses multiple Ampeg 810's paired with 18inch cabs. Obviously this is on a big rock stadium with a professional sound guy, but is there any merit to it? Because an 18inch is larger than a 15, would the tonal difference against a 410 be large enough to work in a combined way, or will it sort of be mushy like a 115 with a 410? My idea was that the 18inch would provide a super beefy and thick subby lower end, with nice definition on top fro the 410. What are your thoughts?
