Know before you buy
The offset tweeter design is engineered to reduce diffraction from the corners of the front baffle. This creates a more precise, centered stereo image, allowing you to pinpoint instruments and vocals more accurately within the soundstage.
The D9 features a passive radiator that significantly boosts low-end output, allowing it to reach down to 64Hz. While they provide impressive bass for their size, listeners who prioritize deep, cinematic sub-bass will likely still want to pair them with a dedicated subwoofer.
With an 8-ohm impedance and 88dB sensitivity, the D9 is relatively efficient and easy to drive. A quality integrated amplifier or receiver with 50 to 150 watts per channel will provide more than enough headroom for clean, dynamic performance.
The D9 is specifically optimized for small to medium-sized rooms. While they are capable of filling a larger space, their design prioritizes intimate, critical listening, so they perform best when placed closer to the listener.
The D9 is designed as a bookshelf speaker and does not include integrated wall-mounting hardware. For the best audio performance, we recommend placing them on dedicated speaker stands to isolate them from vibrations and position the tweeters at ear level.
