well, im selling my current junk and going big this summer, need something in the meantime and have a cerwin vega vega!84 (i guess it was made around 1999/2000) kicking around and I'd like to try a t-line. My armrest is getting cutout for the port on my next project, and i want this to fit in that hole

the hole is 8.5 wide x 20ish high (im pretty confident the trunk comes up through part of it, idk yet, gutting on sat and will double check), distance from front of seat to rear of trunk is 49inches, 44 to back of seat

so here is what my very limited knowledge figured out:

tline.jpg


t/s specs:

Free-Air Resonance: fs 35 Hz

Total Q: Qts 0.323

Mechanical Q: Qms 4.56

Electrical Q: Qes 0.865

Compliance Volume: Vas 0.7 ft 3

Maximum Excursion: Xmax 1.20" (+ 0.60")

30.4 mm (+15.20 mm)

Voice Coil DC Resistance: Revc 3.5 Ω

Volume Displacement: 0.04 ft3

any suggestions for improvement?

the only one i really got was that maybe there should be less surface area, but the sub mount diam is 7in, and the port is 7x7, i guess i could make it shorter and mount from the top with the sub through the rear deck, cuz i already have an 8in hole there. if someone can design something, or tell me whats wrong, much appreciated guys.

 
i really dont have the patience for that

i stick to my graph paper and straight edge for actually designing, that is just for dimensions and an idea of design
