well i am planning on building 6 of these, i have all parts on hand, so i decided to build one, and measure it before i proceed.

they will be tc2+ motors, with 6" spiders, a reproduction of the original tc1000 coil, sa8 cones, and baskets. the leads were stitched by me.

the first parameters were with the coils paralleled

R(e) = 1.005 ohms

Fs = 38.36 hz

Qts = .356

Qes = .376

Qms = 6.706

Le = .732mh

mms = 112.6grams

vas = .1479cu. ft.

spl = 79.88

these were in series

Re = 3.95

fs = 37.68hz

Qts = .331

Qes = .351

Qms = 5.882

Le = 2.874mh

Mms = 121.5 grams

Vas = .1422cu. ft.

in case any of you are used too see vas in liters those are both just a tad under 4liters.

now i will build a test box see how she sounds, and if i am pleased will build the other five.

that sub looks.... sexy great job!!

Sweat.

Did you use software to help achieve your goals? SpeaD? WT3 for specs?

thank you, i wanted something light and under stated for the dustcap, so i went for plain paper, on this one i made one small boo boo with the glue on the cone by the dustcap. it can be seen in the last pic, hopefully i can get the rest perfectly clean.

from a physical aspect when building subs the dustcap is without a doubt the hardest step for me. lol

Very nice looking woofer. Let us know how they sound

i just bought my wt3, but as of yet i still do not use any software for deciding softparts.

i have built a few subs, but other than one, they have all been with motors that i am very familiar with, so i can get close too were i want, just from knowing the motor so well.

i still have ten subs on hand that i built in the past with the above method, before purchasing the wt3, and i measured them all this past week, and all but one were around were i wanted them too be.

the one turned out too be way off from what i intended, but it should work wonderful in a large sealed box. it explains why the damn thing was always so peaky in every different ported box i tried it in. oh well.

I've read experience outweighs all other tools used when designing a driver.

Unfortunately I have no experience. Kudos to you.

Not sure where you are located. I could have a good conversation over a couple of beers with you
