I may go with the SEOS 15" to better match the woofer.
That B&C driver may just have better dispersion than most 15" drivers..

Pretty good design.

You can still see though that the horn is loosing pattern control below 2 kHz. This basically means that from 900 Hz to 1.7 kHz will be "emphasized" ever so slightly. (..or "blooms" on a 3D waterfall.) Subjectively this often results in a forward mid-range with some loss in depth.

The 15 SEOS will allow a little lower crossover all-else equal.

As to which driver - why not try the Eminence you have? Can't hurt.

In your search you might also look at some of the less expensive driver's from MCM Electronics. At least one member was very happy with their inexpensive 10" pro driver, even when compared to more expensive drivers.

Model before you buy because they might need a big box too (if that's a problem).
It's very much volume dependent.

ScottG,

Thanks for the comments.
I agree that the SEOS 15 is a better match. While the SEOS 12 are a bargain, the Solid surface SEOS 15 are attractively priced and a better fit.

Haven't bought anything yet, so I am looking at options.

I have never heard a horn I like(and have not heard many), but I find when there is a design that has a lot of good engineering collaboration, its worth building, even if it turns out not to be my thing.

Thanks. Since I do not need a lot of volume, and have subwoofers, it should not be a big issue.
I can Linkwitz transform them in a sealed box to whatever I need, as long as I have some extra power.

It seems the SEOS 15 has a recommended lowest crossover frequency of 850Hz so that might be ok. Haven't seen any plots though, it's just the manufacturer/dealers recommendation.

It has a 1" throat though and there are not many 1" drivers which can go that low.
I think BMS has a couple that get close.

Never really looked at their drivers since they don't sell to Europe.
The BMS driver I had in mind costs about the same but if you count in duty&excise (+28%) and VAT (+another 20%) it is a LOT cheaper even without shipping.
At least over here, no idea what the BMS 4550 costs in North America.

Helmuth,
I did the rookie mistake of double posting.
