Speaker unit is the soul of the speaker, her temper was directly determines the characteristic timbre of a sound.

Treble unit usually diaphragm material classifications generally have three major categories: namely, hard ball, soft ball and composite film ball. Hard ball with aluminum alloy, titanium alloy and other light metal material, Ultra Platinum alloys, surface through chemical treatment, its timbre brighter skin, has a high resolving power. Soft ball using Silk soft film, listening to interested tone and smooth soft on, expressive. Composite film ball is used in several material diaphragm, such as the diaphragm use "wire-Juan + aluminium film" composite membranes. The loudspeaker has both a hard ball that bright tone quality and analytical ability, and wire-Juan soft dome natural flow, structured sense of hearing. Current common treble unit of materials mainly titanium film, wire coatings, films, etc., in pv multimedia speaker selection in pv-film and silk film ball treble-dominated, and generally felt that the latter out of treble is better than the former.

Bass unit currently common used in the manufacture of bass Horn material mainly paper, ceramic pots, bullet-proof fabrics, wool, polypropylene, etc. Cone: a rigid and flexible utilization and, high internal damping, easy to mix with other advantages, naturally rich timbre, bass. The disadvantage is moisture-proof, the time of manufacture of consistency it is difficult to control. Because of the low cost of cone, it is heavily used in 300 $ multimedia speaker. Ceramic pots: on the human voice and classical music performance is very delicate, with regard to transient in bass, plump, dynamic properties, Basso, precise positioning. Suitable for performance loud film sources of infectivity and shocking. Bullet-proof fabric pots (weaving pot): there is a wide frequency response and low distortion that can withstand more power, you can create a warm, natural and deep, aggressive low-frequency, transient, dynamic music effect is very good, strong bass who was passionately fond of choice. If you are a super fan of the game, select the bullet-proof cloth speaker to play those explosive scenes, fierce arena, games, is a very good choice, that magnificent feeling is cone, or other general material speakers can match.
