RE: 4x10 open back cab needs speakers

Hey Vaughn , need to load a 4x 10 cab , open back , powered by a rebuilt sound city lb 50 plus , I gutted the SC and used the partridge transformers and built a Hiwatt 50 watt amp into it , tight fit ! How a bout ET 10 mixed with something ? Suggestions ?

Hummm ... the big question is ... what's the amp sound like?  Is it lacking in anything?  Maybe a bit stiff with those big trannys and stiff filtering?
