Yeah I had the 8 inch for an Allison 6 referb project I did a year or so ago and the drivers were top notch. I have no doubt these 12 inch ones will absolutely deliver the goods... I just need to decide on their application now...

I took inspiration from Karatestu- also Stevetheshadow- built diy BBC but mid & tweeter forward firing & 12” upfiring.

That sounds like a fun project! Any photos or a link to a thread about them on here?

One of the ideas I’m toying with is also a BBCube copy but using a concrete cast rather than plywood. I wanted to do a concrete cast cube ages ago but bottled it and just did the Allison refurb instead. I think now might be the time to actually give it a go.

Doc,

Could you post cut out and basket (recess) dimensions for the drivers as I'm sure, like me, some do design work before ordering them?
