Default Horn/TL combo

I have been mulling over where to go with my next speaker project. I have come fro pro multiway world and found my way to FR speakers as a result of the forum. I love FR, but they have their limitations. I will be exploring the AN 15 OB tied to woofer as an extension of that, but have also decided to go down the horn road as well. This is mainly due to Lynn's Beyond the Ariel thrad. Having not heard a horn system, I want to something a little cheaper than what he has arrived at, so I will be having to make some choices. ANy suggestions are appreciated, but what i was thinking was either a 12" or 15" pro woofer in a TL/MLTL, TQWT....whatever else of some sort, crossed to either a 1" or 1.4" Horn driver in either a JMLC or Iwata horn. I may try a cheap SEOS platic 12" since it is only $25 each as a first dive, but ulitimately will finish with a pure horn type. If I go Iwata, i may try DIYing them. Otherwise they will come from DiySoundgroup. THe HF drivers I am looking at are the new polymer ones from Faital Pro. THey are new and interesting and have been recommended by a fellow audio enthusiast. SOrry for the ramble. Be forewarned of many more like it

This is a pretty well tried design, been built in decent numbers in many places around the globe.

Easy to build, many suitable drivers, easily adaptable to 15" too.

Thanks Ingvar.
Will look very similar, probably, with the exception of the horn sitting on top vs integrated into the cabinet. I am worried about how far up a 15" can reach effectively. We will see.

JBL 2226H can be run up to 2KHz if you wanted to. Make the horn as big as possible so you can cross as low as possible this will give you greater woofer options and the larger horn will hold polar control to as low as possible for better imaging. Just my two cents worth. Best regards Moray James.

A baffle to fit a 15" can also fit a wider (lower reaching) horn....

Looking at Faital Pro drivers. If i am going to spend money on JBL, it will be on Alnico 416B. Also looked at beyma, as they tend to have very good distortion numbers. Waiting on MJK sheets, as i lost my copy on computer. Been looking at jmlc 400, iwata 600, and e -jmlc. Ejmlc and iwata are kinda ugly. I like traditional Iwata horns betteur. Wait a second, i am not suppose to care how they look.
System will be biampedl at first, giving tim efor passive to develope.

Trying to decied about straight BR or Horn. Slot loaded BR design is now very real possiblity, but I like the resonant dampening effect of MLTL's. Horn is either going to be horns.pl 400 JMLC or Diy wooden IWATA. Havent decided.
