Rare Acoustical Power Labs Bookshelf Speakers 3 way sound very good. Kinda of odd ducks here,, hope someone wants them. Found this info on the net. The Lankraff TLO is a vintage speaker model from Acoustic Power Labs with the following specifications: a. Frequency response of 28Hz-40kHz\. Power input of 30 watts RMS. Peak power input 300W musical impedance of 4 ohms. The woofer is definitely a Infinity Woofer from the QA line. The flat spot on the dustcap is a dead giveaway. The cone tweeter-Midrange is also an Infinity. Out of the WTlc speaker. This is interesting, information. The company Acoustic Power Lab (APL) was founded by sound engineer Raimonds Skuruls and specializes in loudspeaker frequency characteristics correction technology and professional audio. Their work involves modern DSP hardware and software, not the production or use of vintage Infinity speaker drivers (such as the EMIT or EMIM drivers). Since 1983, Infinity has been part of Harman Internati.
