NS-500Ma Large Seal Cabinet 3-Way
NS-500Ma Components: Die cast speaker frames(all three mounted in diecast aluminium frames to prevent basket resonance)
Tweeter - 5 cm Beryllium Dome JA-0544
Midrange - 10 cm Composite Dome JA-1214 (Titanium Carbide) Edgewise voice coil, OFC ribbon wire, driven by a strontium magnet. Yamaha's choice of this midrange driver was over & above the beryllium choice, less brassy dome surface. The composite dome mids are much more forgiving of source material than the beryllium mids of the NS-1000.
Woofer - 30 cm Carbon Fiber Dome JA-3109
The carbon fiber 12" driver in direct comparison to the NS-1000 makes much deeper and more easily accessible bass. Also, this cabinet has a larger volume than the NS-1000.
