Home Speaker Asylum

General speaker questions for audio and home theater.

So much for "simple" first-order crossovers!

All the successful "true" first-order designs I'm aware of (which maintain 6dB/octave acoustic rolloffs at least two octaves either side of corner frequency)employ complex response and impedance compensating filters in parallel with wide-bandwidth drivers. This includes Dynaudio and Thiel, as well as Vandersteen. The battery biasing I've not seen before. There's a lot more to this first order thing than just a cap and a coil!

If you're looking to upgrade to all boutique parts, Vandersteen might provide you with the schematic if you ask nice. It's not like you're gonna go out and try to clone speakers with complex enclosures and proprietary drivers.
