TL damping

kro5998 · 18th January 2007, 09:45 PM

I've build a speaker setup with closed cabinets for the mid/high's and transmissionlines for the low end.

The only thing left to do is to apply damping material in the transmissionlines.

I know that the damping influences the impedance of the TL but that is not an issue since i am using seperate amps for the TL's.
Using more damping material decreases the amount of high frequencies radiated by the port but what should i look for when using speakerworkshop?
Does the output of the port have to fall of above the resonance frequency with a first order slope?

any input would be welcome

Kees.

You should post this in the fullrange forum, as there is a great deal of TL experience there.
