I'm looking to get a subwoofer with minimal depth, I ran into the DD T1508 and was comparing them to shallow mounts (Pioneers, Kicker CVTs, Earthquakes, RE Audio, JL Audio-all 10"s) I have aprox 5 1/4" mounting depth under my seats (2009 F150) which one would sound better 60/40 SQ/SPL wise in a ported enclosure? I'll have around 1.0cf of box space to work with. Thank you!
