Build Your Own?

I just finished these they are new cabinets for speakers I had already built. They use high quality ScanSpeak drivers and I love the way they sound.

Djn04, thats an interesting design. I bet it sounds good. I built a replica of this: http://www.humblehomemadehifi.com/Andromeda%20Mk-II.html

I was studying sound schemes and speakers also comparing to get better results when building my own custom made speakers.

I have followed some online forums and built my very own electrostatic/planar speakers. Amazing what you can build given more time than money. Google for some examples. I had also been a previous owner of Maggies (20.1's) so I know what agood planar sounds like.

Folks,

1. what is the best way to measure the frequency of a ported speaker?

2. Secondly will stuffing more accoustic damping material in the box change the frequency? thanks
