Even if all tweaks to "The Emken" fail, or put it better, come short of accomplishing a satisfying performance, then...they can serve up to 300-400 or so in a F.A.S.T. with uFonken on top on them . The downside would be reduced efficiency and...there are better 12" drivers for bass duty than the Lta...
Or, perhaps go the Econowave way...
Nevertheless, it is Fun exploring the limits of tweaking this one...even if it ends like this:

OY! They're already providing satisfying performance in my lounge Tweeks will only make them better (as he whispering silent prayers). In my lounge my ears are in charge......until Mrs JRKO says I need to move them

Chris and Dave, the speakers look great!

JRKO, remember, they don't have any tweeters hooked up yet. They are listening to the drivers all by themselves and they are propped up on tables without proper room placement. Just placing them on the floor will change their sound. I'm sure they sound terrible right now. Wheels and a handle might help for moving them around. I'd love a pair!

Funny that i have a pair of old KLH's just like the one hanging on the wall. They don't sound very good to me compared to anything I've recently heard. But i was recently in a store where they were playing records (Rock & Soul on 7th Ave, NYC) and i much preferred the old pro sound speaker to the more modern KRK's or whatever they had drilling holes in my ears.

I'm not sure you need this help, Dave, but if you want I can measure them to see where the high end starts dropping and where the woofer starts to beam. Might help decide what kind of tweeter to go with.

I could bring my rig over and do it outside at your house.

oooooh the toys you chaps have!!! I wish you were just down the road from me.

My two jug ears and cat with no taste for classical music are the most accurate measuring systems I have

Does distance from speaker have any effect/affect on the beaming of the larger driver?

I'm only $150 into my rig (excluding laptop and amplifier costs). It's not that expensive. That said though, some people measure with a $2 panasonic capsule. And it works darn good too. You could do it too

According to the microphone no. Beaming is only related to angle. However, the closer you are, the more small movements change angle. With that though, the further back you are, the more the reflected sound can impact the tonal balance.

So yes, distance matters, but it's all related to the room, speaker location, listening position, etc.

I was planning on contacting you anyway to come out and vet me on some other measures (nearfield measures & interpretation) having 2 sets of kit would be interesting.
