Re: SpiritWind Monitors

Next week I am working on a special woofer module for my SpiritWinds. However, the one using the SB29 for the Kairos will work perfectly for it, because the Kairos and the SpiritWinds are very close in sensitivity and bass extension. Both speakers you mentioned need at least a couple feet from the w...

SpiritWind Monitors

I wanted to let you know, due to the interest in this design that I have received I have made arrangements for Meniscus to offer it as a kit. It uses the Audio Technology 18H52-17-06-SD midwoofer and the Scanspeak D9900 Revelator tweeter. You're on your own with the faceted rosewood cabinet though ....

Re: The Kairos and Continuum Three-Way Loudspeakers

Jeff, Interested in what makes this a "universal" circuit... how well will it work in application to other bass drivers and monitors? -v What makes it universal (or close) is the fact that most woofers are operating in a flat, pistonic range below 500 Hz or so, and the damping resistor he...

The Kairos and Continuum Three-Way Loudspeakers

I have been asked many times about making a three way version of the Kairos and the Continuum. I know several have done so with powered woofers, however, there’s a lot that can be said for a properly designed three-way when it comes to smoothness, low distortion, and proper tonal balance, as well as...

Re: New Eclipse 5.25" woofer....

I find it strange that distributors such as Meniscus would produce their own drivers when they represent other driver manufacturers who now become competitors. Competing with your distributor is not cool. You mean like Parts Express and their dozens of Dayton drivers? Or the ones that have been mad...

Re: New Eclipse 5.25" woofer....

OK. I have finally finished some measurements, and actually listening to the new Eclipse W520R-8 woofer and wanted to share what I have found. Here's a pic of the new woofer: http://meniscusaudio.com/images/W520R8.jpg The woofer is a 5.25 nominal driver using the same frame as the Aurum Cantus AC130...

Re: Kairos (noob) Build (: will need help :)

From your picture, it doesn't look like the front baffle is slanted back at 14 degrees. If it is not it will begin to create a dip in the response in the crossover region. One thing you can is if put some feet under the front edge so that the speaker is tilted back the right amount. In you wanted a ...
