Them parameters are for the 500 watter... the NKO. I'm wondering about the DKI myself... the TKO I looked at, and the largest volume/lowest tune I could find was 1.84 ft3 with a 34hz tune at rated (500 watts). That's tryin to keep the excursion within limits... any bigger volume at anything tuned lower than 34hz and any lower tune makes the box small (no low end extension) so I found a happy medium (1.84ft3) and well... you know... lolBut hey... for a 500 watt $100 sub the response looks pretty decent...
I think I read those parameters correctly... 23mm "Peak to peak"... and ... wow... a 3" VC on a 500 watt sub, I think if those coils hang and you watch the box volume/tune... they look okay to me
Still couldn't find parameters on the DKI 12... that's the one I was talking about not finding parameters for BTW... Those look FAR more interesting... read some of the reviews... lol
