haha sorry. hard to hold the phone, talk and do the work at the same time. Better than nothing though. I am starting to get the hang of running t/s specs. I am about to see what the difference in the specs will be when the sub is wired in parallel vs series.

Sounds dumb as hell, and I am not going to make a video of it.....but added bonus, can test 9V batteries and find out if they are still good! Had a couple I had sitting around for a while.....turns out they are all still good ;)

Firm believer in letting my cars do my talking!

You can't rush quality, it doesn't happen overnight. Quality takes time and dedication, but the end results more than pay for it.

Re+Res- 29.1 ohm

Ro-9.81 ohms

Qms- 5.55

Qes- .57

Qts- .52

Mms- 224.77

Cms- .000101

Sd- 50.27 sq in

Vas- .53ft3

Parallel-

Re- .70 ohms

Fs- 33.4hz

Re+Res- 7.5 ohms

Ro-2.29 ohms

Qms-5.75

Qes- .59

Qts- .53

Mms- 265.77

Cms- .0000854

I am no speaker builder and dont really know what these numbers mean, could someone tell me if it looks like I did this correctly?

That looks fantastic actually! The numbers should be the same whether parallel or series. With the exception of the impedance numbers obviously. Nice work! Very consistent
