SS15 or Tham 15?
Have been looking at building 8 tapped horns, drivers i have are B&C PZB40's
Have simulated these in horn resp and must admit im impressed with the results if loaded in the Tham15
But just wondering how these drivers would fair in the SS15 ? found a few details , but for the life of me i cant work out how to plot it horn resp
Be greatfull if someone could do this for me
specs are ...
Nominal Diameter 380 mm (15 in)
Nominal Impedance 8
Minumum Impedance 6.6
(50 –500 Hz)
1 700 W
Continuous Program2 1400 W
Sensitivity (1W/1m)3 97 dB
Frequency Range 40-2000 Hz
Voice Coil Diameter 100 mm (4 in)
Winding Material Copper
Former Material Glass Fibre
Winding Depth 21 mm (13/16 in)
Magnetic Gap Depth 9 mm (19/32 in)
Flux Density 1.15 T
Also available in 4
Ω, data upon request
Thiele & Small Parameters
Fs 39 Hz
Vas 112 dm
3 (4 ft3)
Sd 855 cm2 (132.5 in2)
X max ± 8 mm
X var ± 6.5 mm
Mms 123 g
Bl 24.3 T·m
Le 2.4 mH
From the B&C database, these drivers have an Fs = 43Hz and the Xvar or Xlim are not known. The driver can be used in a SS15 and in a Tham :).
Thanks Djim .. i think i may build both and do an A/B test
The SS15 is a seriously nice and well balanced design, all be it in the good company of the other nice ones floating around here, I look forward to a comparison between the two that has caught you eye, no matter the outcome, yes seriously :)
PS. Jbell - you're toast :) (and I do emphasize the ":)" )
Good luck with the builds, and thanks for sharing.

Game on friend !!! ;)
This is seriously one of the more respectful and knowledgeable sites around, and part of the reason I frequent here.
I too look forward to the builds.
This should be fun to watch :)
JohnnyPyro do you have a passable measurement setup so we can get some data?
Keep in mind that the SS15 models with higher output but the Tham15 is about 2/3 the size. 9.2 ft3 vs 6.6ft3
Build an ss15, and compare against one of my tham15's. May save you some build time / costs.
TH one slice challenge?:)
