Ever since buying an active DIY speaker kit from Siegfried Linkwitz (inventor of the LR2 12 db/octave crossover) which incorporated an active crossover for a 2-way speaker system, I've been a huge fan of active crossover speakers. Later Andrew Jones created a line of Elac speakers (Navis) that also had active crossovers, although Andrew's includes built-in amps as this is a commercial product instead of a DIY kit. Kevin Voecks of Harman is another huge proponent of active is better than passive, however Harman seems unconvinced that audiophiles would accept an active speaker design. I'd love to upgrade my modest passive speakers with a high performance "DIY Rixos" inspired kit, especially my in-wall and in-ceiling speakers which Rixos is particularly well suited for. Maybe Anthony would be willing to sell a kit to Audioholic's members who are more technical than the average audio consumer. The kit could be as simple as a pdf that included the part numbers for the drivers and which supplier to buy from, plans for the speaker box, and biquad filters for a miniDSP. I assume the tweeter lens is the only physical item that would need to be included as it's so integral to his design.
