Re: Building a cab.

Hello all

Just putting a question out to all here. I'm considering building instead
of buying my next lot of cabs. I've been doing the research and have found
heaps of info but still can't answer one question, so any advice is greatly
appreciated.

I'm considering 2 x10 + 1x12 speakers in each cab. Is this possible? Most
of the info out there all descibes matching drivers, but I want something a
bit different

Thanks

What is that supposed to do for you? A pair of 10" is about equal in surface area to one 15"; for a 12", a pair of 8" is closer.

This'll be gobbledygook, but here goes: if the impulse
response of the two chains of speakers is a lot
different, they'll be fighting each other. You also have
to watch the impedances.

I see two wiring strategies - series/parallel or pure
parallel. For series/parallel, you'd need two 4 ohm small
speakers and one 8 ohm large one. For pure parallel, two small
16 ohm and one 8 ohm.

As to the cab design, I'd guess you'd need to design two cabinets
with the same footprint, them merge them.

Don't assume you can just add elements and get good results.
