The Pure Audio Project Trio15 TB is a high-efficiency, open baffle speaker system designed for audiophiles who appreciate a modular, DIY approach. It features two 15" Eminence Alpha15a woofers arranged in a D'Appolito configuration with a Tang Band W8-1808 8" full-range coaxial driver as the center driver. The open baffle design provides a large soundstage, superb clarity, and a natural, lifelike music presentation with a frequency range roughly from 29-32 Hz to 20 kHz. The speakers are shipped flat-packed in multiple shipments and require simple assembly with basic tools. The design allows for driver and crossover swaps, enabling customization to personal taste and room acoustics. The Trio15 TB is available with bamboo or German oak panels and includes options for various crossover kits and driver upgrades. It is praised for its dynamic, detailed sound, deep bass impact for an open baffle design, and excellent sensitivity above 96 dB. Dimensions are approximately 54 cm wide, 120 cm high, and 27 cm deep, weighing about 25 kg (55 lbs) per speaker. The speakers stand on adjustable spikes or Soundcare Superspikes for floor compatibility. The product is still manufactured and supported with upgrade kits available.
