Neil Blanchard Designs creates high-performance mass-loaded transmission line (MLTL) loudspeakers for discerning DIYers and listeners. Known for meticulous engineering and clear build manuals—now complemented by assembled “good/better/best” crossover options from E-Zee’s Crossovers—the range includes compact stand-mounts and the ultra-slim Tower 4T4, tuned to 25 Hz. In-room sensitivity is carefully measured and documented, and the MLTL-6 has earned praise, including Old Guy HiFi’s 2024 “Speaker of the Year.” From flat-pack CNC kits to premium parts selection, Neil Blanchard Designs delivers remarkable bass, imaging, and long-term listening comfort.
