correct T/S parameters for 416-8b?

[sean19]

I found two set's of T/S parameters for a 416-8b one old set from altec lansings unofficial home page these are (xmas 0.15) (ohms 6.90) (vd 19.2) (fs 25.10) (vas 26.47) (Qts 0.32) (Qms 7.05) (Qes 0.33) taken at 4' at 1 watt. Then i have these taken at 1 meter at 1 watt off of the altec pro website under there vintage section (wmas 0.13) (ohms 6.5) (vd 16.6) (fs 24) (vas 22.9) (Qts 0.23) (Qes 0.24) (Qms 6.4) plus there are more parameters under the altec pro site that i have never seen before and don't really understand. So is box modeling software wrote for parameters taken at 1 meter or 4'? Hey Zilch when you come up with 7.5 cuft with two 4" ports 5" long tuned to i think it was 32hz what T/S parameters did you use?

I would take the time to measure them myself before cutting wood. You can buy a woofer tester for around 100,00 from parts express that will do it for you. A lot easier and cheaper than building boxes that may not work.

Just a suggestion, don't hit me :bash:

All the more reason to test the pair you have
