Show your Bill Fitzmaurice cab

What are the weaks points of simplex 112 in relation to the Jack 112 ? What will I lose if I build simplex 112 instead jack 112 ?
Thanks

You will loose volume in the midrange.
Bills charts show identical performance in the low end for a jack 12 or simplex 12. The simplex is going to have a more neutral traditional sound,the jack is going to have a huge midrange boost in comparison

Yes to what Jared said. I would also add (subjectively) slightly less overall sensitivity. Mine are Simplexx 10(s) and Jack 10(s) but I think it correlates to 12.

And as the name suggests the Simplexx is a much easier build.

Build a standard ported cab for the beyma. BFM cabs do not work well with the wrong drivers or with modifications. Half the time they don't work well with the proper drivers...

no complaints here and I've built a J15 and a J210 lite.

Way to go! If I was building Bill cabs I would do the same, just for the kicks

They were a blast to build. They're unique, sound incredible, and you can't buy them in a store.

Man these look like old vintage speakers - really nice
Plywood with finish can look so good.
