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.

Two sets of speakers – TSW 410 and TSW 110. One hour West of DC and Baltimore. TSW 410 are what I would consider floor speakers and the 110s are bookshelf. They come from the same line of speakers. Run them in series or parallel, look it up. Can wire them together into two larger speakers. Both sets speakers have been refoamed and the surrounds are in excellent condition. Solid wood on the top and bottom not particle board or MDF. Overall excellent condition and aesthetically pleasing to look at. Great speakers that sound good and won’t break the bank. Acoustic Research TSW 410. These speakers are renowned for their solid oak cabinets, titanium dome tweeters, and warm, detailed sound signature characteristic of the original Acoustic Research brand before its acquisition. The TSW 410 features an acoustic suspension (sealed box) design, which provides tight, accurate bass response. Design: 3-way acoustic suspension (some sources describe it as a 2.5-way configuration where both woofers operate in the bass, but only the mid-woofer handles midrange). Tweeter: 3/4-inch nitrogen-fired titanium dome with acoustic lens (liquid-cooled in some descriptions). Mid-range: 6.5-inch carbon-filled poly cone. Woofer: 8-inch carbon-filled poly cone (some listings specify 6.5-inch, but 8-inch is common for the 410 model in the 3-driver layout). Frequency Response: 46 Hz – 40,000 Hz (-3dB). Impedance: 4 Ohms (minimum 3.6 Ohms). Sensitivity: 86 dB (some sources cite 89 dB with 2.83V input). Crossover Frequencies: 450 Hz and 3,800 Hz. Dimensions: Approximately 24.75″ H x 12.25″ W x 11.75 D (63 x 32 x 23 cm). Finish: Solid oak veneer (often oiled walnut or pecan). He TSW 110 is a 2-way passive speaker featuring a sealed box (acoustic suspension) enclosure design. It utilizes a 6.5-inch woofer and a 0.75-inch titanium dome tweeter. Its frequency response ranges from 68 Hz to 40,000 Hz (-3dB), with a crossover frequency set at 5,000 Hz. The physical dimensions are approximately 10 x 15 x 8 inches (25.4 x 38 x 20.3 cm).
