and not very encouraging.
The set up was as follows: a Lowther ex4 playing from ~12k down in a big ~100Hz tratrix. A Murata up on top, and a 15" Beyma on the bottom. The Beyma is in an Onken so the results may not be fully indicative of performance in other configs...
I tried a variety of combos for Lowther to Beyma and played with the 15's range as well (experiments using a dsp as electronic xover only -- i.e. no delays -- then switched to a makeshift simple passive filter for the "best sounding" result.
To cut a long story short, the "best sounding" result in that context was: Lowther 200-220, Beyma 50-~200. All other solutions with the Lowther playing lower sounded somewhat honky.
The Lowther cut off higher made the mid-bass lumpy (the Beyma didn't have enough magnet strength? wasn't "fast" enough?).
Amps as before 300b / 2a3 / an old Audiolab. For full range duties I used the Audiolab, the 300b's 7 watts didn't get us anywhere (not even whispering).
I'll try again with a stronger SET.Rerurn to Romy the Cat's Site
