The BHL Crossover! December 26 2013
It's been a while since Boozhound Labs came out with a new design... but the wait is going to be worth it :)
Introducing the BHL Crossover. This is a 2-way 12dB/octave active crossover that can be configured for any crossover frequency by selecting the proper capacitors and resistors. It uses all discreet components - no opamps! The filters are sallen-key implemented with JFET buffers. It uses the same great parts as the rest of the kits.
Choosing a crossover frequency is simple, using a chart provided in the assembly manual. Changing this frequency once it is built will require replacing parts.
The boards are just over 4"x4" and you will need one board per channel. The price has yet to be set, but this is a much more complex design and requires more than twice the number of parts as the phono stage, so I expect it to be somewhere in the $199 range.
I just ordered a set of prototype boards, so it will be a couple weeks until I can offer a fully tested design.
If you would like to be an early-adopter, please email me. I can probably swing a preorder deal.
