These are custom Tonian Lab's Model TL-D8.1S speakers in excellent conditions based on the highly regarded PHY-HP high efficiency wide bandwidth H21 LB15 Sag - 8" drivers. They also use the custom TLR ribbon tweeters by Tonian Labs. The external cabinets are based on the Tonian TLD-1 style as seen in the photos. The specs are 98db sensitivity, 16 Ohm, and about 43 - 40hz. Lots of good reviews online. They are very natural sounding and non-fatiguing I am not the original owner. Paypal use please add 3%.
