Hey, I am looking for my next up front sub. Need to run a small box of course and I have been running WinISD charts of these subs: RL-i8 RL-i10 Image Dynamics ID8 d4 v.3 Dayton Audio 10" TITANIC III A Qtc of .71 is the goal. CHART#1:RL-i8, ID8, 10" TITANIC GAIN CHART: RL-i8, RL-i10, ID8 SPL CHART: RL-i8, RL-i10, ID8 I have about 280-350 watts and already have a .25 cu ft box. This is about as big as I want to go upfront. Looks like the ID8 has the potential for good output with my power but the RL-i8 & Rl-i10 are more in line with my box size? May try another box program. Any thoughts?
