X3-06 EXOTIC T35    
The Exotic T35 is a classic dome midrange tweeter with high sensitivity and a smooth, extended frequency response.

A coated fabric dome with integral surround manufactured by Dr. K. Müller in Germany  ensures excellent performance and consistency. This supplier was among the first in the world to offer fabric dome diaphragms, and did produce the diaphragm for the famous 1.5” Dome Tweeter H087, developed by Seas in 1968.

A high efficiency Alnico V ring magnet in a carefully designed system contributes to high sensitivity and low distortion. A large and well damped cavity in the pole ensures a low resonance frequency and smooth response.

A generously underhung 35mm voice coil wound from copper-clad aluminum wire further enhances the sensitivity. Flexible lead-out wires and venting holes in the aluminum coil former help reduce noise to a minimum.

A large diameter 7mm thick precision machined aluminum front plate with moderate horn loading ensures linear frequency response and represents an extremely stable platform for the magnet system and the moving parts.


Frequency response


The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees, mounted in a 0.6m by 0.8m baffle. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m. The impedance is measured without baffle using a 2V sine signal.


Specifications

*IEC 268-5, via High Pass Butterworth Filter 2500Hz 12 dB/oct.

SEAS这段日子不知出了什么问题......

E0049-08S W16NX001

Precision cast, machined and surface treated magnesium cone acts as a piston through the audible frequency band without showing any sign of midrange resonances.

A unique radial reinforced rubber surround reduces radial resonances and prevents surround break up at large excursions.

Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear and modulation distortion and increase overload margin.

A copper phase plug reduces compression due to temperature variations in the voice coil, increases long term power handling capacity and eliminates resonances in the cavity inside the voice coil former.

The extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment.

Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.


Frequency response



The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 10L closed box. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.

H1224-08 L18RNX/P

L18RNX/P is a 6,5” High Fidelity woofer with an injection moulded metal chassis, intended for bass reflex and transmission line designs.

Stiff, yet light aluminum cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion assosiated with soft cones.

Large magnet system gives good transient response, and the bumped back plate together with the very long, and light weight copper clad aluminum voice coil allow for extreme coil excursion with low distortion.

Extremely stiff and stable injection moulded metal basket, keeps the critical components in perfect alignment.

Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.

BASS-REFLEX·低音反射式聲箱設計的關鍵點：確定聲箱諧振頻率Fc及附加聲管的諧振頻率Fb.


不同音程的兩個樂音同時發聲，聲音效果完全諧和的，謂之完全協和音程，純一度、純四度、純五度、純八度為完全協和音程。

純一度 → 同度

純四度 → 2個全音 + 1個半音

純五度 → 3個全音 + 1個半音

純八度 → 5個全音 + 2個半音

聲箱諧振頻率Fc → 附加聲管的諧振頻率Fb

音程純四度

聲箱諧振頻率Fc → 附加聲管的諧振頻率Fb

音程純五度

上部聲箱諧振頻率Fc1 → 下部附加聲管的諧振頻率Fb2，音程純五度；

下部附加聲管的諧振頻率Fb2 → 下部聲箱諧振頻率Fc2，音程大三度或小三度；

如此，Fb2、Fc2、Fc1可成大三和弦或小三和弦。

云夜已深 往事朦朧依稀 浮華暗褪不會再現 沉夢已休 往日豪情哪去 從頭再醉 新的美夢已舊
