Just starting a new thread seeing what is up with John J and the team at stryke.com.. Any new driver or PR info John?
plan to have 2 new drivers from TC shortly. The new HE15, and the UE15. Both will be $425 to start, and if sales go up and I can purchase in large quantities from TC, I will be able to bring that down.
This looks like the parameters for the new HE15:
Fs: 25.3Hz
Qes: .43
Qms: 10.1
Qts: .41
Vas: 76L
Xmax: 30.65mm
Re: 6.5ohm
Sd: 720cm^2
BL: 30.56Tm
SPL: 87dB 1w
MMs: 386g
In the 22" cube enclosure with dual 3000gram 18" PR's, the F3 point is 17.2Hz!!! It does however have the bump in response due to the high inductance.
The UE15 will be more for sealed box use. I posted parameters for this woofer, but I have 2 options to choose from. The one is what I posted on the bass list before. This would however have a bump in response due to the high inductance. The other will use a slightly shorter Vc. Xmax will be around 25mm instead of 30.65mm, but it uses the copper faraday motor design. This brings the inductance down to about 3mH and eliminates the bump in response. It also gives much lower distortion and a higher upper response limit. I don't have complete parameters on that yet, but i'm working on it.
