Mark K's Speaker Pages

...when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science...Lord Kelvin

02/06/10-You can find updates on Charlie's 2 way budget collaboration here.

01/09/10- Northern CA audio DIY. It's coming in April. see www.ncdiyaudio.com and the threads at the Parts Express board and HTguide. I'm going to try to work with Charlie to have a really good turnout, with multiple high quality speakers to audition. We'll post these as folks sign up. I'll have my measurement setup so you can measure your speakers, even if you don't want to demo them. We'll have some nice door prizes, and some talks on various audio topics by some well respected, but currently anonymous guests. Come one, come all. I will have the ER18DXT, RS22528A and my old Mini, which I've temporarily pulled out of storage for a low output unit for my wife. I actually like it a lot, when you aren't uber cranking the SPL's.

I'll do my best to have the RST dipole up and running. I really want to experiment with the RS28 soft dome and maybe, the DXT horn for this. Of course, this means remeasuring. This is no easy task-it has to be done outdoors, 10 feet or so up in the air...

Blog hacked!

Oh well, so the wordpress blog wasn't that secure. I still have my old page on the RS225 dipole which I will dig up shortly. But no big loss. I plan on doing a new set of tests with the RS225 dipole, and will just post in the coming months.

The ER18 preliminary ramblings are no more, but no great loss, since the completed project is well documented in the gallery section.
