Hail César – From the pen of Frank Tchang, acoustic resonator auteur, comes new brand Avantages Audio and the speaker model César. Like Duevel, it's an omni with a mirror-imaged dispersion lens on top and a refracting lens at the bottom. The upper array creates 360° radiation for two 5-inch Alnico widebanders whilst the lower one reflects a downfire 10" magnesium/alu alloy woofer in all directions. Together it nets 25Hz-20kHz response. Optional super tweeters adds output to 35kHz. Sensitivity for César is 90dB/4ohm. Dimensions are 126x57x35cm and weight is 40kg/ea. Pricing is €13'000/pr. Add €900/pr for the super tweeters.
