I discovered today that the seal boxes i have my subs in had an enclosed volume of .50 ft^3 (14.2l) which is the minimum MTX suggests for the the T81044. They have 5 recommend sizes from the .50 up to 1.00 ft^3. MTX recommends the .63 ft^3.
What is the audible difference between .50, .63, and 1.00 FT^3 box volume?
Is a single reflex bandpass (or any other enclosure) better for accurate deep bass over a sealed box?
