- Dedicated Music Room customized
I hired a small firm to design a dedicated music room in my unfinished basement which was no small feat. A contractor was hired to build it to spec and it was finished in January 2007.
- Hemi-Cylindrical Diffuser / Bass Trap for Front Wall
A DIY hemi-cylindrical (poly) diffuser that doubles as a bass trap having OC701 fiberglass within its cavity. It's a 160degree arc from a 48" diameter Sonotube with red oak veneer on the exterior. The hard exterior diffuses mid/high frequencies in about a 110degree arc. With a total thickness of 30 inches, the hemi will absorb down to about 65Hz [1130/((30*7)/12)=64.6]
- Front Wall Corner Bass Traps
A pair of DIY hemi-cylindrical (poly) diffuers that double as bass traps are in each corner. Eash is a 100 degree arc from a 48" diameter Sonotube with OC701 fiberglass in its cavity. They're covered with black speaker cloth to visually dissapear into the black coloured front wall. The total depth is 39" (27" radius + 12" air space) which absorbs down to about 49Hz. All hemi-diffusers can be pulled away from the wall to whatever depth is needed so as to tailor the low-end absorption.
- Side Wall Reflecting Panels DIY
I built 3 reflecting baffles for each side wall. They are 3/4inches thick and run about 12feet long. Each baffle can be opened to any angle between 0 - 90 degrees. Right now the bottom baffle is open 30 degrees so that ear-level reflections are sent upwards to the ceiling diffusers, whereas the middle and top baffles are both open 20 degrees. The bottom baffle has a pair of GIK D1 QRD-like diffusers at each side wall's first two reflection points to help widen the apparent sound source width.
- Skyline Diffuser for Rear Side Wall Treatment
A DIY Skyline diffuser for the rear right side wall. Uses 8 different cell depths in 1.5" increments with a maximum cell depth of 10.5". Being conservative, 10.5" is 50% of a 645Hz frequency which it will very effectively diffuse down to and likey another 0.5-1 octave lower. * Prime Number used = 547 * Primitive Root = 2 * 26 Columns * 21 Rows * 501 individual blocks of wood!
- Hemi-Cylindrical Diffuser/Bass Trap for Rear Wall
Another two DIY Hemi-Cylindrical (poly) diffusers - one per back wall corner - to diffuse mid/high frequencies and absorb low frequencies as its interior is stuffed with OC701 fiberglass. Dynamat Xtreme (for car doors) was put on the hemi's inside to help reduce resonances and add stiffness. It's a 130 degree arc from a 48" diameter Sonotube.
- GIK D1 QRD-like Diffusers for rear wall
6 are placed on the back wall (3 columns of 2) in front of 3 GIK Monster bass staps.

- George Stantscheff Lightspeed Passive Attenuator
Passive attenuator that uses the special LDR (light dependant resistor) which has the ability to change it's resistance according to how much light LED (light emitting diode) is shone on it, hence it can control the volume without any mechanical contacts needed in the signal path. www.lightspeedattenuator.com
Fantastic sounding and very powerful despite being a 6 watt/ch. SET amp. With the KR Audio PX25 tubes and Sophia Electric 274B tubes and NOS input tubes.
A 2.5 way with 1" tweeter and twin 10" drivers. High efficiency speakers (97dB).
Two servo controlled subs each with a 15" driver and 370watts Class A/B each sub. Wonderfully musical.
This is a bi-directional line conditioner filter and Cardas power cord all in one for the Audio Aero CD player.
