18 Sound ND2T – The Lightest Compression Driver in 18 Sound’s Range, with Tangerine Radial Phase Plug
The 18 Sound ND2T is a 1.4-inch exit neodymium high-frequency compression driver built around a proprietary tangerine radial phase plug design — a genuinely distinct phase plug geometry from every other design documented across this session’s HF coverage, whether the 3-slot circumferential, 4-slot next-gen, BEM-optimized, or 3P proprietary architectures found on 18 Sound’s other compression drivers.
At 1.5 kg, the 18 Sound ND2T is, by a narrow but genuine margin, the lightest compression driver documented across this entire session — even lighter than the ND1424BT’s already featherweight 1.6 kg, confirming this as 18 Sound’s most compact and portable compression driver platform.
The self-centering d-kit for accurate and fast servicing is a specific reliability and maintenance feature documented directly in 18 Sound’s own feature list — the diaphragm kit’s self-centering design streamlines field replacement, ensuring precise alignment is maintained without requiring specialised centering tools or extensive technician expertise.
Design and Construction of the 18 Sound ND2T
The pure titanium diaphragm assembly is built on an edge-wound 61 mm (2.4-inch) aluminium voice coil — matching the same coil scale documented on the ND1424BT and HD2000/HD2020 platforms, though here paired with the distinct tangerine radial phase plug rather than the 3P or 3-slot circumferential designs found on those siblings.
The copper ring for reduced distortion and increased output provides the standard electromagnetic distortion-control approach documented consistently across 18 Sound’s compression driver range. The neodymium ring magnetic structure delivers a substantial 2.0 T flux density from the driver’s genuinely compact and lightweight chassis.
At 1.5 kg, 104 mm overall diameter, and 76 mm depth, the 18 Sound ND2T’s proportions confirm this is 18 Sound’s most minimalist compression driver platform — smaller in overall diameter than every other neodymium driver documented in this session’s 1.4-inch coverage, and lighter than all of them.
Performance and Applications for the 18 Sound ND2T
The 18 Sound ND2T delivers 110 dB sensitivity across a 0.8 – 20 kHz frequency range, with a recommended crossover of 1.2 kHz using a 12 dB/octave or steeper high-pass filter. The 80 W AES / 160 W continuous power handling is modest but appropriate for a driver of this genuinely minimal scale and weight.
For applications where minimum weight is the absolute priority — portable PA systems, compact touring rigs, and any cabinet design where every gram of compression driver mass matters — the 18 Sound ND2T’s combination of record-low weight and the self-centering d-kit’s field-serviceability makes it a genuinely distinctive choice within 18 Sound’s compression driver catalogue.
Available in both 8 and 16 Ω, the 18 Sound ND2T provides system design flexibility matching the rest of 18 Sound’s neodymium compression driver range.
Conclusion – 18 Sound ND2T Compression Driver
The 18 Sound ND2T is the lightest compression driver documented across this entire comprehensive session — 1.5 kg, built around a genuinely distinct tangerine radial phase plug design and a self-centering diaphragm kit specifically engineered for fast, accurate field servicing. At 110 dB sensitivity and 160 W continuous power handling from this minimal footprint, the driver delivers a compelling combination for weight-critical applications.
For portable and touring systems where minimum compression driver weight is the defining requirement, the 18 Sound ND2T represents 18 Sound’s lightest and most compact solution documented in this session.
