I really like the Kapplite. I have several 3015s and 3015LFs. Ive been using one in a Greenboy Fearful cabinet with my Bassman 800 now for a couple years.
I just picked up a really nice 1969 Kustom 200B-1 with 215 cabinet. I opened the cabinet and it has Carvin PS-15 8 ohm speakers in it. I have one 3015 neo on hand and just ordered another one to try in the Kustom cabinet. I wonder if anyone of the forum here has tried the Eminence 3015 neos in the Kustom cabinet. They are very efficient at 100.8 db 1w/1m. They are also 7 lbs lighter that the PS-15. Ill post again after I install them in a couple days.
