Always place RAD bookshelf speakers on appropriate stands at ear level and approximately 35-80 cm. from the back wall for optimum performance. RAD speakers are designed with excellent off-axis performance. In most homes, people move around or sit in different spots. Good off-axis performance means the sound stays clear and accurate across the room. Instead of one “perfect” listening chair, you get great sound over a larger area, which is better for group listening. Controlled directivity aims for a smooth, predictable drop-off in sound level as you move off-axis. This means the reflected sound in the room has the same tonal character as the direct sound, which our brain blends more naturally. Every room has different acoustics, but controlled directivity reduces the room’s “fingerprint” on the sound. You get more consistent performance between different listening environments. In short, wide dispersion gives a big sound but can cause more problems in reflective rooms. Controlled directivity is like a spotlight, still wide enough to fill the space, but focused enough to keep the sound clean, balanced, and consistent. Experiment a little to see which placement will optimize your RAD speakers in 'your' room.

Warranties are transferable only in Canada. You must have the original proof of purchase. See our warranty page.

RAD speakers are built with precision-moving components. Key parts like the spider and surround start out naturally stiff, so your speakers won’t reach their full dynamic potential until they’ve had time to flex. Play at reasonable listening levels. In general, 80-100 hours is a good average. Start with music you know that has good dynamic range.

RAD speakers are covered by a 5 year limited warranty, starting from the date of purchase. Warranty only covers Canadian customers.

Bi-wiring is a speaker connection method where you run two separate pairs of speaker cables from the same amplifier output to a single speaker that has two sets of binding posts, one for the high-frequency drivers (tweeters) and one for the low-frequency drivers (woofers). The idea is that separating the high and low frequency signals into different cable runs can reduce interference between them, potentially giving cleaner sound. How to Bi-Wire Your Speakers Chinook speakers support it Look for two pairs of binding posts on each speaker, usually labeled HF (high frequency) and LF (low frequency). Remove the jumpers Unscrew the binding posts and take out the metal jumper plates connecting HF and LF terminals. Connect cables to the amp Both cable sets go to the same output terminals on your amplifier (red to red, black to black). Connect cables to the speakers One cable pair goes to the HF posts, the other to the LF posts, making sure polarity (+/–) matches on both ends. Tighten connections & test Power up your system and play music to ensure both high and low frequencies are working.
