The jist of the video was price versus the quality of what you are getting:
-Bad QC (on this particular woofer) - if you pay attention, he made no mention of potential glue failure - just that it was a sloppy job for a company that prides themselves on having hand-built woofers. (A little side-note, good friend of mine worked for DD last year, and at that time, according to him - the longest experienced woofer builder they had was around 6 months).
-Cheap basket - no, I can't say I've seen one break, but do you believe that savings in cost is reflected in the price of this woofer?
-Lightweight dustcap and cone I applaud - but not flimsy. It's one thing to be able to withstand a 3kw burp (and not shred, as you mentioned). But resisting cone deformation is something these softparts will NOT be good at (which will directly impact SQ), not to mention the extremely limited suspension on an otherwise 'beefed' up woofer... some poor design decisions here + poorly executed craftsmanship = underwhelming woofer...
I'm really not prepared at the moment to go into the gimmicky neo-slug (SuperCharge add-on) they offer on top of the ferrite motor, but I think it speaks volumes that if it were such a great idea - why isn't every other woofer manufacturer offering something similar?
In the end - sounds like we both agree on at least one point - neither of us would pay $350 for that particular woofer...
