Default XO protyping box: "The Box of Doom"

Hi,

I just found Keith Kidder's BoD

BoD

( I searched here and found nothing, so I thought I'd post it. )

There's some serious work and expense gone into it, so I guess 'you' would have to be building LOTS of speakers to justify the cost?

With so much component variability, wouldn't too low a Z potentially be a problem for an amp, and what sort of xo topology, ie LR2, Bessel etc would you end up with?

Keith's design and construction is amazing, but wouldn't a 'cheap' active biamped solution be more (cost) effective?

comments? thanks, Grant

I'm with you on the last. I got a DCX2496 (and a full set of I/O transformers) to do 1st order prototyping. Once narrowed down, i'll be happy to use aligator clips for acyual passive, i don't do enuff mutliways to make something like the BoD worthwhile.

AudioXpress sells a commercial, budget version of this kind of thing

Datz nutz!

But the multi-tap inductors are the key to making it all fit. =)

The BoD has been around a long time. I seem to remember reading about it ten plus or maybe closer to fifteen years ago on the old Bass List. At that time simulation software was "very" pricey and this approach would have been quite viable. I thought it was pretty neat and despite what some may say, it works!

Best Regards,
TerryO
