Celestion SL600Si with sturdy metal stands. Ive cleaned them up and painted in the front driver/tweeter mounting plates. The stands were also painted in black. Very accurate but analytical almost clinical speakers in my opinion... These speakers need lots of current. Consecutive Serial Numbers: 732494 & 732495. Collection from Chalfont St Peter. Unique cabinets fabricated from a 0.5-thick, Aerolam (aluminum-honeycomb) aircraft flooring material. While low in mass, thus minimizing energy storage, it is sufficiently stiff enough for the resonances of its panels to be pushed almost two octaves higher in frequency than with a conventional wooden cabinet. The contribution to the overall sound from the flexing of the enclosure walls will thus be moved away from the region where instruments and voices have their energy maxima, and will also be lower in level. The result should be a low delayed-resonance signature, with correspondingly low levels of midrange coloration. Because the walls of the enclosure will now be virtually transparent to midrange sound, it is filled with carefully graded foam to absorb as much of the woofers backwave as possible. - (Taken from Stereophile article: https://www.stereophile.com/standloudspeakers/744/index.html) Specifications: -two-way, sealed-box loudspeaker with Aerolam (aluminum-honeycomb) enclosure.
