Greets!Wasn't aware they folded. Anyway, without the Swift's plans or at least the woofer's T/S specs to load into a TL box program you're pretty much 'dead in the water' unless you're willing to build/have room for an acoustically large pipe horn that ~renders its T/S specs moot.

The Vifa BC series was similar to the their TC line but for OEM use only. Their TC14SG49-09 appears to be identicato this BC version. A data sheet on that driver is in the Tymphany data base at:http://www.tymphany.com/datasheet/printview.php?id=284
Greets!Thanks, I used the Wayback Machine to the defunct D-S-T site and got these which are a bit different, especially Fs:
BC14SG49-08:
Nominal impedance [ohm]8
voice coil resistance [ohm]5.6
Nominal power [W]30
Short term max power [W]110
Long term max power [W]110
Sensitivity [dB]87
Free air resonance [Hz]63
Voice coil diameter [mm]25
Voice coil height [mm]10
Air gap height [mm]4
Voice coil inductance [mH]0.63
Eff. diaphragm Area [cm²]80
Moving mass [g]6.0
Force factor [Bl]4.9
VAS [l]9.6
Qms2.97
Qes0.55
Qts0.47Being Vifa though, I doubt either are very accurate.
I have all the woofers specs.
Greets!As you can see from the other posts, the pdf didn't have what I was referring to. Anyway, now that we have some specs, do you know what sort of response and/or the Swift's published performance specs are, such as its F3? I need to see the Kestral2's internal pic too.
