Hi tormentor,
I noticed in your signature, your also using the 685 and the CM1, how does the CM1 compare to the 685. Kamusta ang bass response ng CM1 vs the 685 ?. I know the CM1 has a hump around 60 hz does the 685 show the same response ?
Dependent sa room yung peak nya usually. Most B&Ws have a big peak at around 100Hz (para sa impact), and another peak (often smaller) at around 10kHz (para dun sa sparkly details) sa anechoic measurement, whether FS or BS (kasama na siguro sa signature "house sound" nila). Yung 685 lang nga relatively maliit yung apparent hump sa ranges na yan, kasi mas litaw yung midrange nya than most other B&W models.
Consumer B&Ws almost never measure near flat out of the box, if you're after measured numbers. I don't think it's a priority for them. I suppose they put more weight on tuning/development by ear.
Eto pseudo-anechoic results ng dalawang speakers na yan:
CM1
685
Obviously mas maganda ang dispersion characteristics ng CM1, yung 685 naman mas maganda ang bottom end extension.
