MEYER HD-1 STUDIO MONITORS

Meyer HD-1 Professional Studio Monitors - like new in manufacturer's boxes, purchased 10-22-2014. Each speaker has separate amplifiers built in for the mid-bass and tweeter drivers. These speakers are used in many studios and are great for high-end audio too. Deep bass is easily obtained from these 50+ pound monitors. Three year transferrable warranty. I have rated the speakers as 9/10, 10/10 is a more accurate description. Shipping (insured ground FedEx) to 48 contiguous states is included at the asking price. Paypal adds 3%

Features & Benefits

Unprecedented accuracy for mixes that translate consistently

• Exceptional transparency for fine control of EQ and effects
• Consistent, smooth coverage pattern for very wide “sweet spot”
• Individual alignment provides matched pairs with pinpoint imaging
• Flat low-frequency response to 32 Hz without subwoofers
• High peak power minimizes distortion or compression

Applications

• Near-field tracking and mixing studio monitor
• High-end stereo and surround sound playback systems
• Mastering studio reference monitor
* Surround mixing for post production

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 exceptionally broad directivity with a generous "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 transparency and a flat frequency response. The power amplifier features complementary MOSFET output stages and operates 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 dissipation. 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 individually tested for maximum linearity and low distortion.
