Meyer Hd-1 pair

Pair of used Meyer hd-1s, second owner. Really incredible monitors, one of them could use some TLC, basically just a refoam job for the woofer, which tends to happen from time to time. I did have it refoamed about 6 years ago and it made a big improvement. Some scuff marks on the exterior, just cosmetic…doesnt affect the performance in any way. They’re heavy so local pickup preferred but will ship.

The HD‑1 high definition audio monitor

is a self-powered loudspeaker designed

for ultra-precise near-field monitoring.

Optimized to approximate a point-

source radiator, the HD‑1 yields excep‑

tionally broad directivity with a gener‑

ous “sweet spot.” Its patented circuitry

minimizes time delays and deviations

from linear phase.

The HD‑1 incorporates a two-channel

power amplifier and a sophisticated

active crossover with optimized pole-

zero filters for acoustical transpar‑

ency and a flat frequency response. The

power amplifier features complemen‑

tary MOSFET output stages and oper‑

ates at class A at low to moderate levels

(less than 90 dB SPL) and class AB at

high levels.

The HD‑1 delivers a high peak SPL with

a dynamic range of over 100 dB, with

extremely low distortion. Its free field

frequency response is flat (within ±1 dB)

from 40 Hz to 20 kHz, with each unit

being individually calibrated at Meyer

Sound's Berkeley, California factory.

The HD‑1 has an active, balanced input

that is switchable between a +4 dBu and

–10 dBV nominal operating level.

The HD‑1's transducers include a low-

frequency 8-inch cone driver and

a high-frequency 1-inch soft dome

tweeter. The low-frequency driver's

ample magnet and 2-inch voice coil yield

high efficiency with rapid heat dissipa‑

tion. The tweeter employs a silk-infused

dome that affords smooth frequency

responses while minimizing breakup

and coloration. Both proprietary drivers

are housed in a vented cabinet and in‑

dividually tested for maximum linearity

and low distortion.
