Hello! I need technical guidance on my DIY bass cab. The design: A 15" scoop-bass bin with 2x10" cab on top. I have the plans for the scoop from here: http://ftp.dancetech.com/article.cfm?threadid=181 The ting is: i want to make my cab like a combo, instead of stacking the cabs. Will it be possible, considering the depth of the 15" cab compared to the depth of the 10"s? My amp is an Acoustic B800h 800 watts/4ohm. The speakers are 2 10's both 300 watt/8ohm, and the 15" is 1250 watts/8ohm. Will i run into any problems? And what driver should i need? What else should i consider before going to work? Thanks you.
