ALTEC Milestone 950
Description
　The speaker system using coaxial 2 way unit 950-8B for pros.
950-8B is a 15-inch (38cm) Woofer equipped with a high-heat-resistance voice coil,It is 2 way speaker unit which consisted of Sloat who penetrates the center, a flower pedal (petal) type phon, and a 1-inch compression driver and which inherits the duplex (Duplex) technology of the Altec Lansing tradition.
The peculiar flower pedal phone has a constant directivity response pattern of 90 nominal value as it is also horizontal/vertical. Furthermore, since it becomes the form near a quadrangle to the inclination range form of a general phon being an ellipse form, it is possible to obtain the same sound quality as an axis top over the large range of listening area.

The enclosure serves as computer simulation based on a Thiele & Small theory, and a bass-reflex type designed by the hearing by the skilled engineer.
Plywood is used for a material at 18mm.

The speaker system using full-range unit 405-8H.

405 to 8 Hz is a 4-inch (10cm) full-range unit of 405 series,The magnetic circuit which uses urethane foam edge, a casting frame, and a large-sized magnet for simple composition called a single corn / full range has realized high output sound pressure called 90 dB/W/m.

In order to employ the inside region of 405-8H efficiently, the passive network circuit for preparing the characteristic seemingly etc. is not made to intervene entirely, but it is designed link a unit and amplifier directly only with a connector.

The enclosure is the bus reflex structure where the Acer-mono lamination plywood of 12mm thickness was used, and wood grain and a layer are given to the exterior.

Klipsch Klipschorn Build-to-order article
892,800yen(one-set, around the 2005 time)
The speaker system which will be developed in the 1950s and has continued being henceforth made over about 50 years. Sale in Japan was resumed for YAMAHA as an agency in 2005.

The loudspeaker structure serves as an all horn type which used the horn type for all the bands.
If sufficient low-pass reappearance is aimed at, in order that a horn may solve the hangup of becoming a huge size, the horn of ideal length was folded up, it has stored in the enclosure, and the merit of the horn scheme is pulled out in the practical size.

The enclosure carries the 38cm (15 inches) aperture Woofer in the lower, and the mid range and tweeter of a compression driver + horn are carried in the top housing part.
By the synergistic effect with a horn scheme, any unit has acquired the natural reproductivity.

The original fall dead horn (bending horn) which the founder pole, W, and the Klipsch of the Klipsch company devised in the 1940s is adopted as the horn of a Woofer part,The cross section has a structure which folded up and stored to the enclosure the exponential horn which becomes large gradually, and which was designed by being based officially.
This horn is installing a loudspeaker in the corner of a listening room,The corner fraction is used as an extension of a horn and the air content required in order to reflect an elastic wave, to double the effective length of a horn and to reproduce the minimum sound of an organ and a steep elastic-wave wave by using like the mirror of the 3rd page of the surface of a wall and a floor surface is secured.
