Did you listen really louder also? There should be more obvious Vs one cell.

Maybe the topic should read "DC Bias in Crossovers (mostly Tweeters)."[/b]
Sounds an idea. Shoot me an email with the post numbers you think should be moved. Don't know what to do about the beer.

Sorry Dave, but full-range guys miss out, but maybe they have had an advantage all along. Talk about the last laugh, maybe they had the last laugh first.


Very applicable to a super tweeter. Usually a single cap is the only XO making it quite important.

Let's see what reaction we get among the Elsinore guys and giving them first op. I would start with Post #446, #450 constinues the basic theory in more detail, and #451 by Salas which has an important video link and finally #471 which shows how to apply to other orders.

Good point, and when I do my B200 OB I was thinking along those same lines as well.

instead of 4 caps would this not work with 2 of twice the required capacitance in series, and the resistor between them.

BTW forgot to post this in my last post, alright I know weve moved on

Exactly.

This shown in this collection, every cap must be double the value:

Has anyone figured a good way to incorporate fabric cover for this speaker that does not affect sound too badly?

I haven't gotten around to making grilles yet, but I did recess some magnets under the leather covering on the front baffle for when I did.

Just wondering if it matters if the drivers are installed rotated 90 degrees?

So vertically aligned vs horizontal alignment. like the below picture.

Im not sure if im going to install like this but thought it might make it look a little bit different to everyone elses.
