Does anyone have any info on HH Invader speakers. I know they have been given a bad rap, however i think i have discovered why perhaps explains why?

Laney VC30 1x12 speaker is too close to the tubes and causes the amp to function poorly..... when replaced by a shallower celestion , there is no longer a problem.

Champ electronics is an interesting site too ....

anyway i bought some HH invader 12" speakers they have markings 41219

and 401 on them they were from a quad , i guess they may be 25-35 watt each or prehaps 50watt each , anyone shed any light on these as i can find nothing on the internet about them
