Here are three different sets of t/s parameters for the same drivers...

Which one is correct?

Both the online store and the forum show the same parameters. These numbers correspond with the numbers published by Lambda Acoustics back as far as 6 yrs ago or so. I'm not sure about the numbers on the main site and why they are different but I will look to correct that tomorrow. Thanks.

Something to remember about T/S parameters is that the suspension is always in hysteresis. Basically that means the suspension is always changing its stiffness especially depending on temperature. Original old school Lambda specs were done in Florida in 80-90 degree weather as that was the temp in the shop at time of manufacture. Wisconsin is just a tad cooler which will stiffen up the suspension some and make the Vas smaller and the Fs and Qts higher.
