New Twisted Flare Port Produces Clear and Tight Bass

The all-new Twisted Flare Port takes advantage of extensive subwoofer development experience. The flared, gently twisting shape diffuses the vortex of air generated around the edge of the port, creating a smooth flow of air. This reduces extraneous noise not present in the original input signal and provides clear, accurate low frequency reproduction. From special effect sounds in movies to the atmosphere of a live venue, you hear bass that is clear, tight and realistic.


PWM Digital Drive High Efficiency Amplifier and Dual Feedback Circuit


The built-in power amplifier delivers stable power output of 250 W with high efficiency while minimizing power consumption and heat production. It does not require an output filter coil, resulting in extremely low noise and distortion. High speed transient response is also excellent. The dual feedback circuit reduces distortion by applying feedback twice, resulting in higher sound clarity.

Advanced YST II for Awesome Deep Bass

Developed by Yamaha, the Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant-current principles to drive the speaker cone with even tighter control than the previous version. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound quality.

25 cm (10”) Cone Woofer Unit with Square Wire

A 25 cm (10”) large woofer unit is used in a front-firing configuration. The voice coil of the driver unit employs square wire with a wide surface area that can be wound more densely to obtain higher magnetic flux density. It delivers high drive force, permitting tight and deep bass reproduction.

Beautiful Design that Will Match a Wide Range of Speakers and Interiors

In addition to the beautifully round shape of the front surface, panels on both sides to create an accent, and a neat appearance, this subwoofer lets you imagine the strength of sound and matches a wide range of speaker systems. Numerous color variations are provided, so you can select one matched to your interior.

Front Control Panel for Easy Operation


The power and volume buttons, which are used most often, are laid out on the front surface of the unit for ease of access. It is inclined at an angle of 45°, making it easy to use even when placed on the floor. An LED indicator is above the power button, so even in a dimly lit room it's easy to tell if it's on or off.

System Control and Auto Standby

The system control terminal can be linked to the amplifier power to automatically turn the power on and off. There is also an Auto Standby Function: If no signal is input from the amplifier for a fixed period, it automatically switches to the standby state, and when a signal from the amplifier is detected, power turns on automatically. This limits the wasteful consumption of electricity.

Other Notable Features

• Low standby power consumption of 0.3W
• Auto Standby switch / Sensitivity selector (high, low and off)
• Phase control (normal or reverse)
• B.A.S.S. switch

Up to 90 Day Returns!

Returns are easy and flexible. We will accept returned goods up to 90 days from purchase with the following restrictions as summarised below. For more details please read our Terms & Conditions of Sale, a link is shown at the bottom of the home page.

Changing your Mind
It's OK to change your mind but please be aware that all goods must be returned in as new, unused and re-saleable condition. This means that all packaging must be intact, all accessories are complete in their original wrappers and any free items are also returned with the goods. Essentially the product must be returned in the same condition as you would expect to receive a new unit in. In all cases the cost of returning the goods will be the customer's responsibility. All faulty items must be returned complete and will be repaired under the manufacturer's warranty.


How we Handle Returns
Depending on how long you have had the goods there are different options availble to you. In the case of faulty items, if the item fails due to a manufacturing fault between 1 and 28 days from delivery we will exchange it for a brand new one of the same model. Any items which are found faulty after 28 days from delivery will be repaired under the manufacturers warranty. For returns where you have changed your mind, please find our policy below:


This is were you return your item and we will exchange it for another item of equal or higher value. If the item you wish to change to is of higher value you only pay the difference. If the item is of a lower value we will issue you with a credit note for the difference which you can spend with us at a later date.

Credit Note
This is where you return your item and we issue you with a credit note which you can use against another purchase with us.

This is where you return your item and we issue a refund back to the same method you paid with. e.g. the same credit card. This is not available after 14 days, only exchange or credit note is available after 14 days.

25% Restocking Fee
If your item is returned to us between 29 and 90 days from delivery we will charge a restocking fee of 25% of the price you paid for the item initially. This will be deducted from the value of the exchange or credit note which is issued to you. This is because  technology in the AV marketplace moves fast, and as a result the value of items decrease very quickly.

Please note we do not accept returns after 90 days, except for repairs under warranty.

To complete your order please call us on 0800 634 4484
9am to 6pm Mon-Fri, 9am to 5.30pm Sat.
