Hey community. I have read here for years, but this is one of my first posts. Anyways I am considering building a custom bass Cab for my Gallien-Krueger backline 600, 300 wt 4 ohm load minimum amp head. This pieces I am considering are simple. A Celestion BL10-200X 10" 8 Ohm Bass Guitar Speaker 200W for speaker, then just attaching 1/4" Male-to-Spade cable running pos/neg and directly thru a hole in the back of the box. I am decent at woodworking, so building the box is not so much the problem, I am just not very knowledgeable when it comes to speakers. The main idea is to make 2 cabs that work well, don't weigh a ton, and I can make for relatively inexpensive. (Around a 3rd of the price of a pre-built speaker cab of similar value) Has anyone used these Celestion speakers inside of a cab before? Or any advice on if they will work with this setup. Is there anything I did not take into consideration, or anything wrong with this setup? I plan on reading up more on box building, but overall I would like some general advice and input on this operation. Apologies if this is long winded, thanks for reading.
