DIY 4x12 cab

[Wherditgo]

im going to attempt to build a 4x12 cab and i am pretty new to all this electronic stuff so i need help. First question i want to put in 2 eminence governers(75 watt each) and 2 EMinence tonkers(150 watt each) will the difference in watts affect function? im attempting to make an 8 ohm cab so all these speakers are 8 ohms how is the wiring done on this to make it 8 ohms. And if there is any other tips you can give me on building this that would be much aprreciated

P.S. if answering my questions think as if your talking to a person with a brain the size of peanut when it comes to this stuff thanks

Had to answer because I can shamelessly plug one of my recent projects

No, the difference in wattage is immaterial.

First wire the drivers so that two 8 ohm drivers are in series. Then wire those two sets in parallel. This will give you 8 ohms.

I'm attaching pics of my 4X12. It is built to roughly Marshall 1960A dimensions but nothing like it in construction: it is a simple glued box.

thanks also one other question i read that if a cab is rated at 500 watts or above it needs speakon connectors my cab will clock in at aroun 450 watts will this constitute speakons and i see speakons used mostly with bass and p.a. so would it be compatible with guitar?

Thought I'd move this over to the speaker section

["Q"]

you might think about mixing up the distribution of the two varieties for a better mix of sound too. i.e. a tonker and gov on top and the reverse for the bottom. I say this because unless the box is elevated you will hear more of the high end from just the top 2 speakers. Also, and I know its more of a hassle to build but, if you only have one cab its pretty nice to have a slanted.

["Q"]

In response to your power/speakon jack question, speakons only really matter if you're going to consume that kind of power(something tells me you're not going to run a 400w amp into this thing and run it to clipping). Also, if you're going to play live spare speakon cords are harder to come by then spare 1/4 in if you happen to kill/lose one.

Could always fit it with a 1/4" jack, and a speakon, then you'll be prepared for anything!
