EICO HFS-10
The EICO HFS-10 is a 3-way bookshelf loudspeaker system that EICO sold as a kit or factory-wired. It was reviewed by Electronics World in its August 1966 issue, and the review unit was built from the kit — described as a straightforward assembly process. The system uses a bass-reflex enclosure with a 10-inch woofer, a 5-inch midrange, and two 3-inch cone tweeters wired in parallel, crossing over at 1,500 Hz and 5,000 Hz. Nominal impedance is 8 ohms, with a rated frequency response of 46–20,000 Hz and a 30-watt maximum power handling.

The reviewer found it a well-constructed, good-sounding system — smooth response free from peaks, clean bass without boom, and a reasonably smooth high end, though not as extended as the best systems of the day. Measured efficiency was quite high at 98 dB re 1 watt input at 1 meter, which made it a good match for low-powered amplifiers, and it was said to reproduce very loud levels without distress at its rated maximum. The one minor criticism was that the silk-like grille cloth soiled easily. It was described as a good value for the kit builder, aimed squarely at the home constructor market.
Surviving documentation is thin on a few points: production years and the original price aren't recorded, and there's some disagreement between sources on dimensions and weight — the review-era specs give 19½" W × 11½" H × 9" D at 22 lb., while The Vintage Knob lists 23" H × 13" W × 9½" D at 38 lb. The review sample's serial number was 13991. Finish options were walnut, oiled walnut, or unfinished.
