I am planning to build a "proper" midbass horn to cover 100 to 500hz to replace my current 80Hz Edgar straight Horn (a compromised design). Efficiency goal is AT LEAST 103db, to match my other horns. The new midbass horn will have a 12" driver, full 100hz mouth area, and possibly 4:1 or 3:1 compression, flare shape not determined yet but most likely -- straight tractrix.
I have a pair of working JBL e120-8 drivers. Are these good in the above application or should I consider a better candidate (used or new)? What I mean by "good" is actually the best available for my application. If anyone tried e120-8 for "no compormise" midbass or compared it to other JBL models, TAD, Presicion Devices, etc.
