Haha. Apparently most DIY speaker builders aren't computer dorks to. Else maybe we would have more members here in the group. I stand alone!!!!! (wouldn't be the first time!)

Hi all, I'm a newbie builder and I have just uploaded some pictures of my first real build. (RoundHouse) subwoofer. I would like to get some comments and constructive feedback. Thanks.

I have been planning to build some speakers for some time now, but then I started reading about ALL the testing that needs to be done...so the Project has been put on HOLD. Any thoughts on this? ANYONE here ever build speakers from SCRATCH that came out Good, without all kinds of testing?

Most of Paul Carmody's (Overnight Sensations, Amiga, Carerra, Hitmakers, Tarkus, and more ...) were designed by him w/OUT taking his own measurements (AFAIK) - which he outlines in a (yellow) "sticky" at the head of this forum.

You have to remember that it is all math and applied physics. I'm not saying you have to be a master of physics buy what I am saying is that most all results are fairly predictable. If the electronic calculattions and acoustic calculations are good then you will end up pretty close to the mark. Then you listen, and based on your listening experience you tweak, and so on. There are plenty of resources out there to help with calculations and computer modeling but that stuff won't always give you a clear indication of diminishing returns. What I mean is bigger wire = better conductor but jumper cables for a bookshelf speaker is silly, and paying the extra $50 to drop THD in a receiver from .5% to .05% is good but payin $1000 to go from .05 to .045 is nuts. Which is better, a curvy Latina girlfriend or a long lean Nordic girlfriend ? The only true answer is whatever makes you happy.

Hello all!
This is 'kind of' what I'm up against as well. I have a super nice set of cabinets that I'd like to install new drivers in. (295-430 and 270-252). I did some math for my Zobel. However, how do you KNOW now, where /what the impedance is to calculate for a cross-over? (Without at DATS or something?). And speaking of crossover calculators, while I DO know it's just a 'yardstick' to get a reasonable result to start with, EVERY online calculator I use, gives me way different results with the same entered parameters. I DO want to get the DATS / mic bundle someday in the near future. It's not exactly in my budget at this point. I did a set of 'hybrid' BR1's. (4 ohm woofer/8 ohm tweeter), just because I had the woofs on my shelf from another B652 project. PE helped me out with a L/R crossover schematic that worked out GREAT! I can't seem to get that help with this project however. I DO know they're quite busy. If anyone could possibly help me out, I'd sure appreciate it!!
Thanks!!

Let's keep "vox" in the OTHER thread ...
