Soundstream T2-12 / Epsilon T3 Parameters.. is spl/m enough compare? Really need help

Apparently, if they had those specs, they dont anymore. nothing you can do I guess

Alright thanks for checking for me.

For future reference all you need for those modeling softwares to give you a response curve is Fs, Vas, and Qts.
IMO that's a decent looking response curve. Cabin gain should give you a decent boost around 50-55hz so you'll wind up with more of a plateau between 35 and 60hz or so when you actually measure response. You might try tuning a little lower to mellow out that peak a bit, but at the end of the day the accoustics of your vehicle will be a bigger factor in determining actual performance.

Just by the mechanical specs it seems like a much more robust platform than what you have and could only be a step up IMO.

Thanks, I'll keep in mind I only need those 3 specs, I think i recall it didn't model the response without those specs but maybe it does, I'm not sure if I tried running it without those specs.

The sub certainly looks much stronger than what I have now, and thanks for the info on cabin gain, I wasn't sure what frequencies were increased in cabin gain. As far as I know the general cabin gain is about 12db, and I drive a hatchback so I guess it would only be higher than that.

Measure from the front of the car to the back (corner to corner is generally peak for purposes of a meter, but end to end will be close as well) and divide by 2 then divide by the speed of sound. You will have a good idea of the frequency at which you will get a boost, it's not just at that one note, but a general hump around that point. Predicted and measured peak in my Jeep with this method (corner to corner) is spot on.

From front to the back I assume inside the cabin. By corner to corner do you mean diagonally across the car? (driver side front to passenger side of the boot)

Cheers.

Not sure about inside the cabin, there may be a half-wave from back glass to windshield as well but that should be up pretty high so it will probably be attenuated by the crossover if it is there. Definitely from each farthest point (so trunk to windsheild)
