Like a Tannoy 12 or 15 ? By loading I mean down to the upper bass or under 200 cycles.

Tannoy Autographs are quite popular.

Here is a link to some drawings:

Doesn't really load the driver much but I imagine a bigger version might add a little something.

I've heard Altec 15" coax in the A7 box, which would be a sort front horn. Works well. Loads to about 200Hz, IIRC.

Have also heard Lowther fullrange in a big horn. Seemed to work extremely well. The Lowther shout was absent, which is good.

What I have is a pair of these Electro Voice EJ1 horns and 12" Tannoy dual concentric drivers out of the V12's. I'm thinking of mating them up - Once I get them together and do some measuring I'll get a better idea of what I'll need to do to get them tuned in with the crossover. What I'm afraid of is the 12 may not go up high enough to meet the compression treble due to the increased loading of the low mid in the horn. If i can get it right it may be a lot of fun to listen to.

Second that. (but I guess the available headroom is still not enough for POOH... )


About the (massive) EJ1, would it be feasible to modify it into a (big) Synergy horn?

The V12's have enough headroom for me when used with my current bass system - they are actually very nice drivers and could use some better cabinets. Not fully loaded horn headroom but close.

I think the synergy horns need to be exact to really work right. Hacking up these horns and guessing on the results may be a disaster for me. The Tannoys are easy and a point source to begin with. The horn throat is beautifully molded and fits a 12 with no compression or diffraction so I'm going to give it a go before hacking them up.

Default Tannoy Westminster

The Tannoy Westminster is another version of the concept. IIRC the fronthorn loads down to app. 200 cycles.

+1, though it sounded s little 'pinched' to me, so when someone wanted a FLH for the 604, the large conical WG I recommended proved a winner according to him. Wish I still had all my old correspondence to see who it was, though do remember it wasn't a poster on any the early audio BBs or web forums.

It was huge, loading to a 120 Hz XO to mate to a centralized mono 'sub' system IIRC.
