Features:

The KEF dual coupled cavity bass system with two 10” (250mm) drivers.
KEF’s force cancelling rod.
Exclusive KEF power activator amplifier system supplies up to 200 watts to each woofer driver for 115 dB output.
Power activator technology features partial current drive.
Switchable home THX and stereo operating modes.
Blend control.

Advantages:

Delivers tremendous bass output to the lowest registers of recorded music and film sound.
Rigidly joins the two woofer drivers to suppress distortion from unwanted vibration.
Comfortably exceeds the home THX output requirement using a single subwoofer cabinet.
Reduces distortion due to thermal compression and impedance variations in the woofer drivers.
in stereo mode, response extends down to 22 Hz ± 2.5 dB. While the upper cut-off frequency is continuously adjustable from 50 Hz to 150 Hz.
Provides adjustment to the relative phase of the subwoofer output compared to the front (satellite) outputs.

Benefits:

Sound effects E.G. Helicopters, earthquakes reproduced with stunning realism.
Produces a cleaner sound.
Delivers a huge amount of bass sound from a comparatively small enclosure.
Superb clarity at high levels.
Provides for optimum performance for film sound or music.
Enables the system to be optimised for the smoothest overall response and accurate transient attack, regardless of its position in the room.

Pros: Outstanding performance. Best subwoofer sound you will find on market for private use. No complaints.
Cons: Powerswitch on difficult spot on rear. Expensive product.

Awesome product. No better subwoofer seen in history before. Outstanding performance. Very crystal and clear low sound. Your home becomes BETTER than a theatre with this subwoofer! Bought it for upgrading my system for private use. I love it for the reason of it's impressive size although it looks like a table (weight 50 kilos) and power output of 400 Watts. I hate one thing. The main power switch is on the back and difficult to reach every time before I use it. I prefer to switch the complete system off when not in use. Details:
AV1 Lucas film THX 22 Hz-150 Hz, -6 dB at18 Hz in stereo mode 35 Hz-80 Hz, -6 dB at 29 Hz in THX mode, maximum output 115 dB spl and a distinguished 400 Watts power handling...

老外也觉得主电源在后方很讨厌，跟我的想法一样，还是把主动功放拆下放在外面使用会较方便。还有原来功放的功率不是500W,而是400W.是最好的低音炮可能指的是它能下到22HZ，而声音还能保持那么好的Q度（弹性）吧？

虽然超重低音的放大器部分独立外置在下放是非常不错的方法，但是要注意的是放大器发热的问题，对于AV1的B类400W往往散热是很难处理的，就算超低音停止工作处于standby的状态下发热量依然很高。小弟觉得会长还是小心处理。 [s:97] [s:97]

因为大熱量,,所以在冷气房中,,因为溫差所以底部会结露,,是设计的败笔

目前我已経把这400W功放,,拆下來放旁边了,,上述问题已経解決了

现在的问题是速度太慢,,我凖备用日立OFC无氧铜改変箱內配綫來加速,,如果不行就换成纯银綫

今天我又买了纯银保險丝及2mm单股银綫,,打算做纯银电源綫及箱內配綫,,另外买了WBT 6N铜套筒做接头

今天也买了几个银焊錫,,相信到时后,,我跟1960兄都会忙一阵子的改机及调音.....

底部会结露用静音电风扇吹底部是不是好一些，风量可以使露点降低。

这个低音炮气流量已経很惊人了,,呼吸量与107.2同,,小风扇会被吹跑吧!!

谢!!

2.0mm的线用在电源盒部分很好，你想做的工作必须要用1.0mm或0.8mm的线材效果比较优秀，1.0mm要用6股，0.8mm要用9股。这个线很中性，必须增加电容量才能凸出中频。每股长度在15cm，自己算算长度吧。
