Don't these amps have a HPF switch on the back of them ?

Could be any number of different things. I assume you've tried the speaker with a different amp to check that the speaker is working correctly? And likewise tested that amp with a different speaker to confirm that the problem definitely lies with the amp? And double-checked you're not doing anything silly with the crossover or desk outputs? (We've all been there...)
If memory serves, the amp only has 30Hz and 50Hz HPF switches on the back so they wouldn't account for the problem you describe.
It would be quite unusual for an amp to fail with those symptoms - I'd certainly be looking elsewhere for the cause first.

Nope, it should have both a HPF and LPF... see here...

And it sounds like the LPF is engaged and needs to be changed obviously if the OP is looking to use it with full range speakers.
