How are the Acoustics/sound within the lows verses each other??Id figure the burch would echo,as the MDF would absorb the ecohing sound??Looking to build for 4-xtra heavy 10s in a x-cab Chevy..Was to be using 1in Mdf as always, but you guys have me considering??Does it sound a bit more heavy/or ??Think I used reg Plywood back in the day when I was broke,yet dont remember the reason for the change.Any other input may change my new install.I dont mind the weight,just the Acoustics??Thanks:wallbash:
