BLAM Signature Medium S 3N50

Reference-quality full-range reproduction

The BLAM S3N50 is a 3" (80 mm) full-range driver designed to deliver exceptionally precise and detailed sound reproduction. With 100 W maximum power, 25 W nominal power and an extended 200 Hz – 30 kHz frequency response, it accurately reproduces both midrange and high frequencies while maintaining outstanding tonal balance.

Premium engineering

The S3N50 features a die-cast aluminium basket, an ultra-rigid carbon fibre cone, IIR surround, long-life Conex spider and a 20 mm voice coil wound on a fibreglass former. An oversized neodymium ring magnet, copper Faraday ring and aluminium phase plug work together to reduce distortion, improve linearity and deliver excellent transient response. Each driver is matched to ±1 dB for maximum consistency.

Anatomy Of The Part Number
You might have noticed that there are many different sets within the Signature range, often differentiated by a single letter or number. However rather than running though the sets proper, let’s instead focus on what individual alphanumeric digits mean:
– KIT – this denotes it’s a full component set or coaxial set.
– MEDIUM – this denotes it’s a midrange or wideband driver set.
– 20, 25, 50, 100, 165, 200 as the middle number – this denotes the woofer size, in millimetres. Whereas 690 denotes it’s a 6×9″.
– S24, S45, S80, S100 as the end number – this denotes the magnet diameter, in millimetres.
– S300 – this denotes the same 100 mm magnet as the two-way set, but in a three-way set.
– S2, S3 – this denotes two-way or three-way configuration in modern sets.
– N – this denotes a neodymium magnet.
– MG – this denotes a magnesium dome tweeter.
– C – This denotes it’s a coaxial set.
