Need alittle help. I am planning on building my first sub and need some opinions on which equipment and cabinet are good for my system and set-up. Here is my set-up: Room size = 12'w x 21'l x 8'h Receiver = Pioneer Elite VSX-24TX with THX select Fronts and Rears = Klipsch KSB1.1 (will upgrade in near future) Center = Klipsch KSC-C1 (will upgrade in near future) System will be used for 50% music & 50% HT I was looking at Partsexpress and talk to them about the: Dayton 12" Titanic MK2 250w Amp (part# 300-794) And they recommended a 3.8 cubic foot ported cabinet (aprox. 18.75 x 18.75 x 18.75) I have no problem making a cabinet (I have access to a nice wood shop), but would like to find some nice plans to build. Can you help?
