DG01 Near-Field Multipurpose Monitors

April 29, 2016 Leave a comment

DG01 Wireframe

DG01 NEAR-FIELD MONITORS
The DG01 speakers are multipurpose mixing and listening speakers designed for near-field use. Despite their size, these desktop speakers were made to be listened to from a distance of only about a foot away.
To achieve the low end necessary for critical listening, the DG01s are designed as a ported box with a 2” port on the rear side. While this causes some loss of transient accuracy, it is more than made up for by the low-frequency extension. These speakers manage to reach an F3 of 38Hz while also boasting a +/- 3dB range from ~40Hz-19kHz. The range is possible due to the excellent drivers selected for the job—Dayton Audio RS225-8 for the woofers and SB Acoustics SB26STAC-C000-4 for the tweeters. With the use of a MiniDSP PWR-ICE125 amplifier and DSP unit for each monitor, a fairly flat response is easily achieved. With the design comes a very strong center image and a large sound stage.

QUICK FACTS:
Crossover: 4th-order, woofer at 2.2kHz, tweeter at 2kHz
Response: +/-3dB ~40Hz-19kHz
F3: 38Hz
Total cost (w/o MiniDSP): ~$400
Box materials: 1/2” MDF with 3/4” birch plywood
Size: 19”Hx15”Wx18”D
Tweeter: SB Acoustics SB26STAC-C000-4
Woofer: Dayton Audio RS225-8

The Royals


IMG_1153

Design by:
Ben Jaszczak

Description:

The Royals are sealed, active, two way speakers intended for small room film mixing and general listening. The front and top of the speakers are made with solid  and unstained Purple Heart hardwood. The design intent for these speakers was to have relatively dry, high accuracy speakers with as far of a low end extension as possible within my budget and mobility constraints. The large sealed cabinet design serves to provide both fidelity, low end extension and clean low end transients. at ± 1dB The Royals achieve optimal frequency response when tuned for a specific room, as acoustic changes in any given room can have significant effects on the frequency response. The overall price of the two speakers was approximately $1,000.

Design:

  • Purple Heart hardwood and Baltic Birch plywood construction
  • Tang Band W6 1721 6 1/2″ paper cone woofers
  • SB Acoustic SB26STAC 1″ soft dome tweeters
  • MiniDSP PWR-ICE125 140W plate amplifier

Tech Specs:

  • Meets THX Standard 85dB with 20dB headroom
  • ± 1dB from 70Hz to 20kHz
  • F3 at 50Hz
