## Description

Product Description Wharfedale Diamond SW-150 Walnut Subwoofer The SW-150 Subwoofer from Wharfedale offers a level of performance previously unheard of in its class, striking the perfect balance between power and sound quality. Revolutionary drive units, amplifier modules and filter stages feature on every model of Wharfedales SW Series of subwoofers. In each model it is possible to switch off all filters and allow the AV processor to control the effective frequency range of the subwoofer. This is preferable in high-end systems. Revolutionary drive units, amplifier modules and filter stages feature on every model. They strike the perfect balance between power and sound quality, offering remarkable sound pressure levels, yet retaining enough control to be considered audiophile in quality. This is possible only through the use of some space-age materials and cutting-edge technology in our drive units. But what is beauty without practicality Solid, well-engineered power amplifiers, dedicated to the production of low frequency energy are used across the range. Power is targeted specifically at the most important section of the bass spectrum, with very little loss and a controlled roll-off allowing for superb integration with all hi-fi and home cinema systems. The filter section controls the integration with your main speakers and ensures the transition is seamless. Designed using six discrete circuits, signal purity is regarded as paramount. Each circuit has a different crossover frequency (35Hz to 85Hz in 10Hz steps). The filter is 12dB/octave on the SW-150 and 24dB/octave on the larger models. Finally, the Tri-lam cone is revolutionary in terms of technology and performance which is one of the most advanced cones ever seen in a moving-coil loudspeaker, coupled with an elongated voice coil with a maximum excursion of 24mm.

## Questions & Answers

**Q: do you have to have a sub out on youre amp to be able to use this?**
A: No you can piggy back the audio out for the speakers
From the amp straight into the left. And right audio in on the sub

**Q: Would i be able to use this subwoofer with my Yamaha rx v359 receiver. And how?**
A: Hello!

In theory, you should be able to take a phono / single RCA cable from the subwoofer output on the back of your receiver and into left or right of the RCA/line input on the back of the sub. Some people opt for a male RCA which splits into two male RCA so that both left and right receive an input but I believe there’s not much advantage.

**Q: Is it possible to connect my hi-fi via the 'speaker lvel inputs' and my tv sound bar using the 'line level inputs'. not to be played at the same time.**
A: If I understand you correctly, yes you can, but you just need care in terms of what you use & when. Yes, you can connect your hi-fi to the sub, via the speaker connections(take care & observe polarity), AND your soundbar via the line-level inputs. 
So if you use your hi-fi(with the soundbar & TV off) then the sub'll work using the speaker level connections. Then, for your TV & soundbar(with your hi-fi off), the sub'll work using the line level(the RCA phono) connections. 
You'll then just need to match up the cross-over frequency and output level of your sub for the different hi-fi & TV/soundbar needs, as I doubt that they'll be the same for both needs. However, you might be able to get a compromise to suit the two types of systems, that'll save fiddling around.
Happy listening!

**Q: Can i connect this to my denon dht-s216 soundbar? soundbar has a single " subwoofer out" connection**
A: Yes, connect a 'Y' phono connector(*) from the Denon soundbar to the stereo inputs of the subwoofer. I guess the soundbar will output a mono signal in the subwoofer output, so even a single phono connector would work, but to ensure a better amplification use both phono inputs on the subwoofer. If set up correctly, you should get a rich, deep sounding low end to your experience. Enjoy!
(* ie. a single phono plug to 2 phono plugs)

### ⭐⭐⭐⭐⭐ Great value subwoofer.
*by P***E on 13 March 2026*

I cannot praise this sub enough! It hooked up easily, adjusted to phase, cutoff and volume precisely. And the result is way better than one should expect at this price point. I have had subs costing considerably more that aren't as musical - and it can cover movie effects for a small to medium room perfectly well. Okay - you can get more out of 250+Watts but to match it for an accurate sound blending well with speakers in an AV system its going to cost several times more. Even the Walnut finish and overall heft of the admittedly big box is pleasing. Again, if you want something in glossy piano black packed into a small form factor its not for you. But as a big punchy and suprisingly deft performer it really can't be beaten for under £200. Its close to persuading me to get some diamond speakers to match if the sound, looks and finish are on a par.
