ALTEC 618 CABS
 
3 Attachment(s)
I'm building these cabs for a 8" driver. I have a pair that I want to try. I also think these might be nice for the BetsyK. They are 2cuft resonant cabs. I'll try the BestyK's as soon as I get some. :) This configuration should be very SET low watt/ volume friendly.

The standard Betsy sounds good in the “reso” style resonant cabs. The K might be too bassy. If you’re buying new, I could send you one of each to try.

That's a good idea! The cabs are nearing completion. When I get to the finish stage I'll shoot you a message.

I've used both Betsy drivers before. OB and box. Really good drivers!

They are amazingly good drivers and even better when you factor in price.

Install a simple phase plug for an added treat.

I have a 7" hole cut in my baffle for rear mounting the driver. Can anyone tell me the dimension of the Betsy measured from the inside edge of the cone?

Thanks for the measurement. Looks like I would have to enlarge the hole.:(

Better than having to make it smaller.

It’s only 1/4” to small so 1/8” on each side.

My measurements are for Betsy K, not sure if regular Betsy is the same.

You could wait for Randy to confirm everything.

I agree with you! :)
