[QUOTE="Crown_amps, post: 2736352, member: 562002"] when i get my tax return for kicks i want to build a new box say .8-1cf SEALED downfiring but after reading about some spiders not being able to deal with the moving mass and gravity im a lil worried. 1. its gonna be for fun and yes i have had MANy people telling me not to downfire and went ahead to build the ''typical sealed box'' front firing in the 1.3 cf range. Its alright and does what i expect but will downfiring make that much of a differnce a lot of ht subs i have seen downfire. 2. No frills easy sat morn project i can tackle myself sub is a alpine type S amp is a dayton audio plate amp 250 watts @ 4 ohms wired to 4 ohms to the dual 2 coil sub vas is like 66 L i think last time i checked [/QUOTE]
