hey do you have any way of measuring the T/S parameters of either the Konaki Hybrid or the X12??

If I can sell my 19Ov.2 than I'd be super interested in either one. I like loud daily bass lol

Crap...just saw that the hybrids are dual 1 and the X12 is dual 4.

I only have a Nine.1 amp.

900 watts enough for the X12??

900 watts will work for either one, actually.

Konaki Hybrid:

RE = 1.75 ohms (series)

Fs = 28.7 Hz

Qes = 0.42

Qms = 6.46

Qts = 0.40

Le = 1.08 mH (series)

Vas = 39.25 L

Little video of breaking in the X12:

Started out with it playing pretty clean, then turned it up a bit to show the physical travel it has (spiders get loud at that level).

Okay, specs on the X12 proto:

RE = 6.59 ohms (series)

Fs = 35.6 Hz

Qes = 0.807

Qms = 4.49

Qts = 0.684

Le = 4.85 mH (series)

Vas = 21.74 L

BL = 22.17 N/A

Cms = 74.03 um/N

I would suggest it for larger sealed or an IB application due to the Qts figure. It'll break in a bit more -- it has four spiders so it'll take a while.
