Re: The Kairos thread

Standard formulas are only necessary if you have a reason to keep the impedance the same as it was. I don't have that restriction when I am designing, so I use values that easy to find, usually parallel resistors of  10, 15, 20 ohms etc. and then series resistors that give the attenuation that I nee...

Re: SpiritWind Monitors

I have kept my SpiritWinds as my reference speaker. I think both drivers in the SW are a little bit better and the overall presentation of the SpiritWind may be the best I have heard. The Kairos are top notch, but I give the edge to the SpiritWinds.

Re: The Kairos thread

The TW29BN may be a little hotter than the TW29R, so you might want to play around a little with the resistors on the tweeter to get a good balance.

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...
