I suppose it's all about a smooth blend between the 12" driver and the compression tweeter of choice for this to be successful. I thought about it and love the whole coax idea but opted for the 'more traditional' wide range approach plus helper woofer and tweeter. The sound is very smooth this way (crossovers outside critical ranges) allowing the 12lta to simply play full out (showing off it's raunchy, fun, dynamic character) without circuits being in the way. I love the purity and simplicity of this type of 3-way.

Whether OB or Sealed, the 12lta is a winner... I'd LOVE to hear the Emken and adopt one for my listening room but i'm in divorce limbo at the moment. I am very enamored by the 12lta regardless of its flaws. It ROCKS like no other full ranger i've encountered.

In fact the most time consuming part so far has been fitting and drilling all those holes in the full length and lateral bracing - the CNC & operator are not always available after hours. Even though it's actually faster by hand with a 1/2" power drill than a belt driven drill press - no matter how large the motor, there's way too much slippage on the latter, and moreover you only need to clamp work pieces once when drilling by hand - this is much tougher going on BB plywood than MDF.

These aren't tiny enclosures - altogether approx 2 5x5ft sheets per side, and it does get a bit wearying moving them around.

Yup - it took me 2 days with help on the first - I was exhausted. Heavy box ain't they?

Wow, that would be a bit heavy! Casters sound like a good idea! Will there be a version of this at DIY Fest this year?

Two of those on the back, a foot on the front, and a telescoping handle to drag it around like luggage!

Given that our target is small PA work, that kind of thing is the goal if the beta gives us good feelings.

I like those wheels Chris! I was thinking about popping a couple of static wheels an inch or two from the base on the back with a small flip-down handle on back at the top. Just lean it backwards and voila!.....

....a matching L & R set of Emken Luggage

BTW when is diyFEST? I counting on Dave & Chris' design & build skills to wow everyone!
