DIY X24 Floorstanding Loudspeakers DIY Open Baffle SpeakersOpen baffle speakers are loudspeakers without a rear enclosure, designed to radiate sound both forward and backward in a dipole pattern, creating a wide, natural soundstage and a spatial listening experience often described as more immersive and less like a single sound source compared to traditional box speakers.This design eliminates cabinet resonances, which can contribute to a "box sound," and results in a more coherent and fast soundVery Dynamic sounding speakers with lots of punchSensitivity is 98dbImpedance is 8ohm nominal4x Emi
This is a seller’s market for used floorstanding speakers right now, and the A$2,100 asking price for these DIY X24s is clearly ambitious, sitting well above the A$1,488 75th percentile from your ground truth data of 12 comparable listings. The median used price is A$1,086, with the 75th at A$1,488, so A$2,100 exceeds the top quartile by a significant margin, making it hard to justify as fair without exceptional condition or rare accessories.
However, if these are the Dynaudio Excite X24s (often mislabeled as “Coherent” or “DIY”), they are highly regarded for their neutral tone, beautiful midrange, surprising bass depth despite small cabinets, and cohesive sound when paired with matching Dynaudio models. Their excellent imaging, dynamic range, and build quality make them a worthwhile buy if the price drops closer to A$1,500 or below, especially in original-owner condition with stands or cables included. At A$2,100, it’s a risky opportunity unless the seller can prove pristine condition and unique value.

Coherent Audio emerged around 2007 from the workshop of Frank Fazzalari in Stoney Creek, Ontario, Canada. A veteran of the speaker-building industry, Fazzalari had spent years crafting enclosures for prominent Canadian brands before launching his own venture. Drawing on this hands-on heritage, the company embodies a boutique commitment to handmade, precision-engineered loudspeakers that prioritize sonic purity over mass production.
The brand focuses exclusively on high-performance speakers, with standout models like the Retro 15 Neo Be—a horn-loaded design featuring a modified Radian 5215 15-inch coaxial driver. These handcrafted units, measuring 22 by 13 by 34 inches, boast exceptional power handling up to 700 watts AES and employ unique aluminum-coned drivers sourced globally for minimal distortion. Coherent also offers modular custom speakers, emphasizing tailored solutions for discerning setups.
Positioned as a niche boutique in the high-end hi-fi market, Coherent Audio earns praise for its drop-dead gorgeous aesthetics and sonically superior performance among audiophiles. It appeals to knowledgeable buyers seeking rare, low-distortion drivers and artisanal quality, carving a cult following rather than mainstream volume.
