Here's a pair of Altec Lansing loudspeakers. Back in the mid 70's National Speaker Company in Denver, CO sold many of these to musical groups throughout the country. They were referred to as "Mini Voice of the Theatre" speakers. I just recently tested the speakers, horns & crossovers and everything sounds great. Each has a 808-8A driver, 811-B horn and N809-8A crossover. Cabinets have a few scuffs and scrapes and a couple of edge dings. I did some light touch-up with black paint.

　　I had a high energy single act in which I used a Fender guitar, Roland 808 drummer and a Shure

　　Beta 58 microphone. And, because of the power & full sound room coverage I was able to play large

　　rooms were there were over 300 people. And, I packed the dance floor!

　　The ALTEC 418-8H Musical instrument loudspeaker is a rugged, 15? loudspeaker designed for use in musical entertainment systems of moderate size and coverage area where true high-fidelity reproduction must be combined with high power output.

　　The 418-8H has a heavy permanent magnet, a structurally reinforced die-cast aluminum frame, a 3? diameter edge-wound voice coil of copper ribbon and a cone suspension having exceptional compliance. It is sealed against dust and dirt.

　　The smooth response and excellent linearity of the 418-8H loudspeaker is achieved by strict adherence to precision design and manufacturing tolerances. The axial retention of the voice coil in a magnetic field, uniform over the full excursion, ensures clarity of music reproduction at high power levels. The low cone resonance, when the speaker is mounted in a suitable enclosure, virtually eliminates all ?doubling? or self-generation of unwanted harmonic components.

　　The 418-8H has a continuous power rating of 150 watts and a frequency response from 45 to 8000 Hz. Its design provides high efficiency, high linearity, low distortion, wide range and optimum cone resonance.
