Bipolar option?
Hello Chris and Dave:
Rather than having both 12pw's on the front face could you narrow things up a bit, make the cabinet a little deeper and put one on the back. This would eliminate baffle step. Could the vent go out the back or bottom? Say with short legs and a nice stone base

With 2 woofers, wide baffle and active XO, I'm not so sure that baffle step loss will be a major issue.
Yes, the vent could probably be oriented on any face, but boundary loading too close to the floor might have some consequences.
On a good day, I don't think about going bipolar, and with the sun shining right now, it's a good day.
'course living on the coast and attending several fests now, you're quite aware the weather and my disposition can be mercurial -

Sure. Skinnier box likely means moving the XO up in freuquency. The drivers certainly won't fight that. A deep bipole will thou suffer from greater bipole dip.
These deal with baffle step in the same way a bipole would... put the XO at the BAS point and turn the woofers up.

This particular design is a heartier sibling of one several years back with EL166 and a Fostex FF85K
Sold them to one of the pounders at work - they didn't disappoint, and have survived intact , including parties with teenage daughters and their boyfriends ( better than might be said about the daughters)

Quick summary from this afternoon's listening session- sometimes more is better. First part of same session was with compact floorstanders with A10Ps and FF165WKs - either of which are eminently livable - but these puppies are something else.
Damping on the woofer TL section may need some tuning -seemed a bit over-damped with a thick batt of 2" Ultra touch on both sides of longitudinal brace - but even so the last system to rattle some of the loose soffit panels in the downstairs room was Tannoy Monitor Gold 12s I built a few months back. Personally I find these already more cohesive than the Tannoys, whose tonality and imaging I just never cottoned to

Apologies if that was one of my MLTL alignments Chris (I've lost track) -if so, I probably went a bit excessive on the specified damping.

More likely that we installed more damping than specified.

emphasis mine - with partial removable back, adjusting fill is easily done
carrying these mothers up a staircase - no so much
I've been called worse.Bipolar
That's more like it.Cosmo kinda guy
Great looking project guys. Hope to hear them next trip over.
they gonna let you cross the border again? - I thought after the last time ....
No customs between Canada and the (semi-)Independent Republic of Vancouver Island. You just have to pay the ferry tariff to get away and back.
