I have finally decided to part w/ my Midbass Horns . unfortunately they are just too big for my room .
when i asked Jeffrey Jackson for some help to build a Midbass Horn he offered to provide his calculations of the Exhilaration III for a small fee. i spent all summer building them and they turned out great . they are very big and massive . all Horn Walls are 1.5" thick Birch Ply . Finished with some clear Lacquer . i used cardas speaker connecters . i will add some Photos , hopefully tomorrow to give an idea on how they look and also provide dimensions. they are designed for 15" drivers and i had good results w/ GPA Altec 515G drivers which i also consider selling . freq. response is usable from 60-500hz .
dimensions are 25x32 mouth opening . length from throat to mouth is 45" , back chamber is 19x19 and 12" deep. so total length is 57" .
these Horns are awesome. as expected , they have the punch only midbass horns have , efficiency is better then 100db , they are very fast and dynamic , and there are no midbass Horns commercially available . so if you always wanted to try a pair and don't feel like spending all your summer building ( summers in WI are short ) , this is your chance .
these horns are big and heavy and i would prefer if someone could pick them up . i am located in wisconsin . i do consider shipping them but that would probably be very expensive . i could strap the horns to two pallets if you can arrange a shipper or try to find a shipping company if you are seriously committed . shipping weight of 120# is just an estimate , i will have to get the exact weight as soon as i find a scale ... as always paypal adds fees , usps MO is preferred. if you pick up its cash .
