Paradigm Titan, Paradigm Phantom v1, a lot of help needed

[duraznov]

Hello, please can anybody tell me the Thiele-Small for the 6 1/2 " woofer from the Paradigm Titan? Or if someone has this speaker, can tell me the measure (diameter and long) for the bass reflex port? I'm trying to clone a pair of Titans, for doing so I have the interior volume ( 12 liters) and que exterior measures, but i think i need the Thiele-Small for calculate the port.... (by the way, i will use the tweeter Vifa D19TD-27-08).


My other DIY proyect is a pair of Paradigm Phantom, the old version with a single 8" woofer.... for that speaker i have nothing! just the external measures... so i will need a lot of good luck or a kind person who has it and measure the bass reflex por for me... thanks a lot!!

An externally hosted image should be here but it was not working when we last tested it.

Should be enough to work out dimensions, though i'd detune it somewhat.

This is from a 1998 or 1999 model of the titan. I have performed a crude t/s analysis. These are not published specs, they're measurements which I took.

Znom: 3.8ohm
Re: 3.5ohm
Fs:40.2hz
Qes: .36
Qms: 7.31
Qts: .34
Vas: 27.6liter

These are not wholly accurate, but something to work with. The box for the titans is 11.2liters, minus the drivers, port, crossover and terminal cup. The port is 31mm x 84mm.

Thanks a lot to both of you, I think the help you gave to me is very useful; since the woofers i'm working with are new but from the 90' (they are replacement parts from an ex dealer here in Chile), well, i have enough for work with the Titans, i'll later tell you how it worked.
