EDIT:  Not sure we are on the same page regarding frequency range for this horn

Well, I don't have any other options.My 42Hz upper bass horn has flat frequency response in 70-300Hz range and -5db in 60-400Hz, so I need next channel to work in full from 400Hz at least (from 300hz better!).I was reading Jessie's project thread and see that his 40hz horn is separated from the frame, but I want to stay time-aligned and I have no place on the frame for another 1x1m horn.That means I need to choose from:
1. 200hz horn without "curl"
2. 250hz with "curl"
Any suggestions ?


The large 42Hz horn would probably want to be crossed over from 160Hz-200Hz at the most which would leave the top octave of the horns range for attenuation.  So what you really need is a horn from about 100Hz to go above it...not going to happen.  The thing about the 42Hz horn is that you can pretty much put it anywhere in the room because the frequencies that it covers do little for imaging or soundstaging.  Of course you can keep them time-aligned if you are persistent like Romy with them in the ceiling behind the listening chair.  Personally I would vertically align the channels that are going to provide imaging and figure out how to do below 100Hz from somewhere else in the room.

Regarding the "curl", I personally would not bother...they take up far to much real estate.
