Default Anyone interested in Linkwitz Transform boards?

I'm designing one for myself and again have decided to offer it to others who may be looking for something similar. I haven't decided yet whether I'll offer a "kit" yet or offer just a bare PCB. I'm trying to gauge interest to see how many boards I should order. Bare boards are $12 in prototype quantities.

You can find details here:

Click on ELECTRONICS and then LINKWITZ TRANSFORM

I'm assuming these are the boards used for building an Orion type speaker?

If so, I'm interested in a set or two- depending on final price, of course.

Best,
KT

Rob,

I would also be interested in a kit if that becomes available.

You should seriously consider not using frames on your website. Also, you devote excess space for your logo and side menu. The scrolling frame that remains is too small to be used to present product or information.

Hmm, I run 1600x1200 at home and at work so I guess I haven't noticed. I'll make a point to check it at a lower resolution to see if anything is out of proportion. Thanks for the tip.

This circuit is not specifically for the Orion since it doesn't contain the EQ for the dipole driver. It only equalizes the low bass. This would be used by folks who are building a sealed box subwoofer who want more extension or control of Qtc from too small an enclosure.

You can find Orion crossover boards at:

http://www.linkwitzlab.com/DIY%20products.htm

HIGHLY recommended, and quite reasonably priced considering the boards are about 7" by 9" each. The circuit board set documentation does assume you have the necessary electronic skills to calculate the Rs and Cs.

on a 17" monitor running 1028x764, the page looks just dandy to me, running MSIE The left frame could be a bit narrower, but overall it's OK for an amateur site.
