This was bought as a high-wattage speaker to my Palmer 112-cab, as an extention-cab to my Fender HR DL. I believe that the Fender combo is loaded with an Eminence speaker which I really like. It's loud and sharp and worked really well along with my old Marshall 410-cab (4 x GoldBack 35's).
I wanted a single 12" with a little extra low-end capacity. The Emi-Swamp was considered, but I settled with an Eminence 1218-speaker, as I'm not that into the downtuned sound...
The result was quite simply impressive. I have used this single 12-cab in band rehearsal, and runned it quite hard (at about 30 W on my VHT 44 Special) to break in the speaker, and both me and my bandmates are amazed at the capacity of this thing. It sounds fuller than my Marshall 410-cab, and just as loud...
Wow..!
