The speaker system which gained flattery nature and a response by constituting a twin drive system for an axis and aiming at improvement in fast of a dynamic range.
The unit of DENON and the Peerless joint development of Denmark is used for a unit.
The twin drive system which used two 25cm corn type Woofers is adopted as low-pass, and the oscillating area equivalent to the Woofer of a 35cm aperture has been obtained.
By using the non press corn paper by the pulp of the system from Northern Europe for a diaphragm, and coating a braking agent in the surface, the division vibration of the high region was controlled and interference with the reflective sound which prevents an air leak and differs in the phase from the core of the enclosure is prevented.
Moreover, while suppressing bending of the diameter direction to a voice coil and improving resolving power, it processed with high heat resistance adhesives in the aluminum bobbin excellent in the heat dissipation effect, and input-proof [ high ]-ization is realized.
The 10cm corn type squawker is carried in the inside region.
This unit makes the back cavity and the frame solid construction with light-alloy die casting, and has prevented the sound interference by the air pressure from a Woofer, or vibration. Furthermore, it was filled up with ring-like glass wool in the cavity, and the low-pass characteristic of a squawker is controlled.
Moreover, a vibration system is the non press corn paper which carried out coating processing by the braking agent at the back,It consists of foaming polyurethane roll edge by which coating processing was carried out by the voice coil which raised the allowable input on the good aluminum bobbin of the heat dissipation effect using the insulating material of high heat resistance, and the braking agent, and low distortion and input-proof [ quantity ]-ization are attained.
Two 5cm corn type tweeters are carried in the high region, and the twin drive system perpendicularly arranged so that directivity might not be given horizontally is adopted.
A unit applies a braking agent and the division vibration is suppressed, since an effective radius is about 1.8cm, it excels in directional characteristics, and also the moving mass is made small at the center cap using the material which molded ultra-thin aluminum foil for the high region characteristic improvement.
In order to suppress a loss in a network part to the minimum and to secure clear sound quality, all the condensers in a circuit are made into parallel connection.
Aluminum plain foil electrolysis type, high proof-pressure metallized polyester film type, a mass large-sized metallized film type, etc. are adopted as the condenser which influences sound quality greatly.
Moreover, an empty core coil is used for the large-sized ferrite bobbin type, the squawker, and the object for tweeters which took the power loss into consideration enough, and the low distorted design is performed in the coil for Woofers.
The sandwiches support system is adopted as mount of a tweeter and a Woofer, and all the circumferences of the unit are firmly attached to the baffle board with the ring and plate of aluminum die casting.
This is reducing vibration of the unit itself and a cabinet.
The enclosure repeats an audition and measurement by 0.5L unit, and is determined as the content volume of 65.5L.
The sound-absorbing material filled up two layers and three layers with three kinds of materials other than the usual glass wool, such as micron wool yarn of superthin glass fiber, and has performed precise sound absorption processing.
Hard particle board was made the material and it had to it, and in order to control and distribute only a harmful oscillating frequency component, by laser holography measurement and audition, aluminum foil lamination butyl system rubber was stuck on the backlining inner side, and natural sound has been obtained.
