speaker plans!

[thebrontosaurus]

so i have these speakers below,
speakers and they are quite tall and awkward to play with. they are tall and skinny and i would like to build new cabinets and i was wondering a few things.

right now it is built with 1/2" plywood. i was wondering if 3/8" would still be sufficient to reduce some weight.

also i was wondering if this new design would cause any problems. plan

this will have those cute little wheels too. that wil be sooo convenient.

thanks,

There's actually quite a lot that goes in to speaker cabinet design, with many variables factoring in. I've come across sites before that had various calculators to figure things out for you.... things like internal volume of the enclosure make a big difference, and need to be optimized, based on various properties of the speakers being used, among other things.

I dont really have much to offer in terms of specifics, but do a little research about building cabinets designed for whatever your intended use for these are. From the picture, it looks to me like they're older stereo speakers?

Try to find a site or person or other resource with information about things like internal enclosure volume, baffle construction, porting (diameter, length of tube, or no port at all?), etc, etc. There's a lot of neat information that can help you get a better outcome out of your time.

I've experienced first hand how a bad speaker cab design can turn 1000W into 6X12" speakers into hardly anything (both the speakers and the cabinet contributed to the problem, in this case)

At a minimum, use 3/4" MDF for the cabinets and try to preserve the same internal box volume as the original enclosure.

is that an old Vox column? if so, dont destroy it. sell it and you'll have plenty for a regular 4x12 stack with money left over.

mdf would make it way too heavy, thats why i ruled that out.

that looks like a standard cabinet design. if you stick to the same dimensions as a known cabinet your probably alright.
your not doing anything too bizarre imo, that would mess up the basics.

the key is the joints...no vibrations and rattling. a flat faced cabinet would probably be even easier than the slant. i'm ripping apart some cabinet 2x12. used and sounds great, but the red felt has to go!
