Betsy & Buck 12

[Randy in Caintuck]

I recently made a change in the Betsy & Buck baffles ….. with a 12" Eminence Alpha driver being used instead of the original 10" Eminence Alpha driver.

They sound good to me and there is an option for an "active" and a "passive" version of the speaker.

Information can be found here.

Happy listening,
Randy

Nice!

The lxmini crossover from the diyaudio store works great for an active version.

Very inspiring, I plan to try to DIY a similar open baffle. Less scary for non woodworkers than a box enclosure

Due to the lack of interest, the Betsy & Buck baffles have been discontinued.

It's a shame, because they were one of the best sounding and versatile speakers that were offered from Caintuck Audio.

For currently available options, please visit the Caintuck Audio website.

Happy listening,
Randy

crossover

Hi Randy,

Since you no selling the Buck 12 version, can you please share what the passive crossover looked like.

I have an Eminence 12 sitting at home and thought I would experiment with it.

Hi Dkalsi,

Sorry for the delayed reply ..... I have been pretty busy in the woodshop ...

On the Betsy & Buck, I ran the Betsy driver "wide open" with no crossover component and only an air core inductor on the bass driver.
It is wired in parallel with the Betsy driver.
If an Eminence Alpha driver is used (10" or 12") the impedance is 8 ohms.

The following values of inductor can be used and you can season the bass response to taste with the value of the inductor.

106 HZ - 12 mH

127 HZ - 10 mH

182 HZ - 7 mH

212 HZ - 6 mH

255 HZ - 5 mH

318 HZ - 4 mH

635 HZ - 2 mH

Happy listening,
Randy

Hi Randy,

Sorry to hear the interest wasn't as expected. I would very much like to try this deisgn out as I have a pair of Betsy's sitting unused right now.

I was curious about your thoughts on this 12" Goldwood driver for the LF. I realize the QTS is a little low for OB but the sensitivity and FS could make up for it.

goldwood 18" is the right one

Hi jwjarch,

Parts Express sells a 12" Goldwood bass driver with dual voice coils with a pretty decent .QTS.

Goldwood GW-412D 12" Poly DVC Subwoofer

I ordered a couple of them and will check them out in separate bass baffles if I ever get caught up on orders .....

The 12" drivers I have used for bass in the past seem to be a bit quicker and tighter than larger drivers and I think that they work better for music if home theater isn't a concern. Just my opinion .....

It should be interesting to see how these drivers work.
The dual voice coils / binding posts allow a lot of options for amplification and configuration.

Best wishes,
Randy

That is a good looking woofer Randy. Thank you for the link and the insight. I'll be curious to see how they perform as well, if you get caught up.
