Definitive Technology Speakers BP 7006 built in Subwoofer/Amp Question


I purchased these speakers without testing them.
I only paid $ 80.00 for the pair.
When I hooked them up  they sounded good even though it became evident that
both built in Subwoofer/Amps are not functioning.
Just Tweeter and Mid range are working.
It has LFE Inputs in back of speakers.
My question:
Should I add an external subwoofer or leave the speakers as is ?
I have a Sansui AU 607MR Integrated Amp. How would I hook up external subwoofer to this amp?
Does anyone own these speakers...I would like to hear your input.
Thank you

I believe these amps are a very common problem. Do a google search,and you will see what I’m talking about. Still a decent speaker for $80. I run def tech subs in my HT,and they have a history of bad plate amps. 
Yes they are. For some reason,def tech had some issues with what seems like most of their sub amps. It didn’t seem to matter if they were powered subs in the speakers,or separate subs.   I do like the way their subs sound,but when they die again,I will look elsewhere.
