Yes, daily use. Looking to get the smoothest response from them. My overall goal is for SQ not brain rattling bass. The only other question I haven't seen answered is: When calculating the box volume do you subtract out the entire port volume, or just the material used making the port? Than just one sa8 would be fine.Subtract the whole port volume and material. also you need to subtract the driver volume. for the sa8 its about .10 cube per driver
