Q. on shootout between time/phase coherent speaker

All

I have a couple of questions

1. What are folks opinions of strenghts/weakness (characteristics) of the famous time/phase coherent speaker lines out there (Thiel, Vandy, GMA, Meadowlark, etc etc)

2. Esp in the under $2k range.

3. Have folks backed up their impression with any scientific (measurements, and/or double blind).

I have Vandersteen 2Ce's in a HT system with Arcam AVR amplification (choose Vandy's as they have complete system and price wise a good choice)

This is an old thread, but that is nonsense. 1st-order crossovers are the simplest and such speakers can be made *very* easy to drive - GMA's sure are.

Hi Pubul57,

I don't know the answer to your question on why Thiels and Vandy's are not so easy to drive but you are right about that. OTOH, they're not extremely difficult loads either, but the point I wanted to make is that 1st order crossovers are an attribute that makes speakers easier to drive, not vice-versa. Thiel & Vandy obviously have other factors at work. I suspect that their crossovers are not nearly as simple as 1st order networks can be. Roy at GMA makes extremely simple crossovers because he fixes impedance and freq. response issues with the cabinet, the way it should be done, not by adding artificial fixes in the xover.

The crossover of the Callisto, for example, is one cap on the tweet and one inductor on the woofer! That's it. Then there is a simple Zobel network on each driver but I don't believe that's part of the crossover per se.
