Design & Final Testing Report


Aries I

Aries I Loudspeakers

Designed By: Kevin “Hexecho” Gray

The Aries I loudspeakers were designed for use as desktop near-field monitor loudspeakers with a large soundstage and stereo image. A stand out feature of the Aries I cabinets are the high-Carbon gray Iron baffles and rear panels, this metal helps to add strength to the speakers while absorbing and dampening vibrations from the drivers, preventing the drivers from causing unsavory resonances in the wooden cabinets. The speakers are designed for an impressive transient response, and low-end extension with smaller sealed box, I wanted to make sure these speakers would give a kick drum some real kick. The speakers were intended for high-fidelity enjoyment along with music production and mixing, sporting a +/- 3 dB frequency response from 120Hz to 20 kHz with a +1 dB boost at 110 Hz.  The phenomenal off-axis frequency response of the Aries I allow it to excite a space with accurately reproduced sound, helping to add to the soundstage. Aesthetically the Aries I speakers sport an industrial style as-cast iron front and rear panels mounted into the deep-red 7 layer plywood cabinets by hex head bolts, and feature a the Aries sign on the outside of the right speaker layered in blue wood dye under the many layers of red.  After all of the metal work and parts costs the Aries I ran a budget of $800.

Design Goals:
Good low-end: F3~70Hz
Use of metal in speakers: Iron panels, aluminum woofer, titanium tweeter
+/-  3 dB frequency response
Bass boost: +1 dB at 110 Hz
Fit onto a desktop: 12″x12.5″x13″ 45 lbs
Great Transient Response
Big Soundstage
