Diamond SW150 Subwoofer (Black)

This has been such a good purchase for me. I own a pair of Q Acoustics M20 powered speakers which are excellent in the highs and mids but lack bass for the size of room they are in. I read the reviews of this and had high hopes and they haven't disappointed. I'm sure there are better much more expensive subs out there but for my ears these are perfect. They need some setting up and dialling in to get bright but once this was complete they made my speakers sound perfect. Just enough bass coming in so they don't sound boomy but give music extra depth and presence. For ref I have the QA M20s in a 4mx5m room with little soft furnishings so it was difficult for them to fill the room, however now it sounds perfect. The crossover frequency give you control over when the sub should add more bass. The volume controls how much and how loud. I had to have the crossover set to 85 as anything below just wasn't pronounced enough, volume at half to three quarters and Phase sound better at 180. Brilliant for the price.

Didn’t really want to spend the earth on a sub so this was at a decent price point for me. Sounds fantastic to my ears. I have volume set quite low but it still rumbles the floors and adds that extra something during action sequences in movies that you can’t get without a sub. I think quality and sound are great at this price and you really are on the diminishing returns point once you go up much from here - or that’s my opinion.

Really pleased with my recent purchase of Diamond SW150 subwoofer. Started researching subs to enhance my already great sounding home hifi. I'm running Alpha 8 integrated amp, Alpha 8 power amp bi wired to pair of B&W DM610 speakers, Alpha 7SE CD and ProJect Xpression turntable. Existing system always amazing sounding but I knew the DM610 stand mounted speakers couldn't give me all the lower frequencies a good set of floor standing speakers would. Unfortunately my room just doesn't allow for a big set of floor standers especially if ideally placed way out from the wall. I was looking for alternatives to improve my sound. So I didn't really know much about subs until recently, thought they were mainly for home cinema or car systems where the main speakers tend to be smaller. Then came across couple of online articles / videos discussing the merits of a sub in a home hifi system. I read lost of reviews and this Wharfdale consistently came out favorably, especially at such a great price.. They were £250 when first release 10 years ago and What HFi gave an excellent review at the time even at that price point. All i can saw is WOW, cannot believe i didn't discover the use of a sub in my set up earlier. The difference to my already excellent sounding set up is huge. I listen to a wide range of music from electronic to jazz although the majority is rock / guitar based. Obviously on electronic dance music, dub, electronica etc the subs presence is really felt. All the huge low end is really brought too life but even on classic rock where the overall effect is less "obvious" so much new sonic information is highlighted. The kick drums for instance, the sense of air being moved by the bass as felt when you are actually in a room with the band. It is really night and day switching the sub on and off whilst playing back almost any style of music. The reviews here on Amazon did have a few conflicting points. Firstly a few people mentioned hum or noise from the sub in either standby or low level in the background. I can confidently say mine is absolutely silent. No hum. I can only assume those who have reported this must have a connection or other compatibility issue within their set ups. Check all connections, quality of cable etc. There seemed also to be some confusion regarding wiring the sub into a system without a dedicated sub output. This is just not a problem at all. If running from an amplifier you simply attach a separate set of speaker wires from the amps left and right speakers out to the subs speaker left and right ins. On my Bi Wired set up i did this from the power amp as thats handling all my low end information. Finally setting up the sub itself was very simple. Connected to my system as detailed above the subs volume is adjusted by the amp. The sub does however have its own volume on the back and this is to adjust it to blend in with the other speakers. A well set up sub should blend in with the overall sound stage and not draw attention to itself. I have mine set at about 3/4 on the volume. Turning it up too high makes it too dominant and too low just lessens its affect. The final control on the sub is the crossover. This is the point that the subs frequencies work up to. Ideally you want a crossover of frequencies between the lowest end of your main speakers and the upper end of the sub. My B&W go down to about 55hz. The sub from 20hz up to around 100. I set the crossover at 65 hz on the sub and this creates a seamless blend in the lower frequencies. These settings seemed very common on all the online tutorials i looked at. I am literally rediscovering my entire music collection with this sub now in my system.

Finally bit the bullet and expanded my setup with this beautifully performing piece of kit - i currently have a 4 speaker stereo setup with 2 bookshelf and 2 floor standers, all running through a cheap denon 7.1 av hifi amp. The quality of sound i got before this purchase was good in the the highs and mids, but to get similar results in low frequencies i had to adjust the settings on the amp, boost the bass etc, which i was always unhappy about due to this distorting the beautiful highs i get out of the smaller bookshelves! The quality of the low range from this sub is unparalleled for the price (my budget is pretty tight which is why i chose this model). Tone is warm and complementary rather than overpowering and offensive, as are some units i have heard in the past. Controls on the back are simple and useful when playing music that doesn't favor the extra bass, although even in those cases, having the unit on but at a low volume makes for a much more immersive listening experience. trialled everything from symphonic orchestral, to house and jungle, and the wharfdale just eats up everything i throw at it. recommend testing the room you intend to use the sub in, for the best 'node', where the bass can extend fully and evenly into the room - it may not be visually the most obvious place, in terms of layout, each room will be different and consideration to sub placement will only improve the fidelity of your system. extremely impressive speaker, honestly struggling to fault it!

Il subwoofer è di aspetto semplice ma è molto ben realizzato e rifinito, il peso è notevole e credo non riscontrabile in altri apparecchi concorrenti di prezzo anche superiore. Le regolazioni possibili sul pannello posteriore sono quelle usuali per questo tipo di apparecchi, compresa l'accensione automatica al ricevimento di segnale audio dall'amplificatore, che mi sembra funzionare correttamente. Il suo intervento è deciso ma discreto (non tende inutilmente a strafare), comunque se si alza il volume fa tremare tutto senza problemi. Rapporto qualità/prezzo eccellente, apparecchio assolutamente consigliabile.

Para mí una de las mejores marcas de sonido. Estéticamente es perfecto y tiene una excelente calidad de graves. Vino muy buen empaquetado y estoy encantado con el producto

Dolce, non ingombrante, presente al bisogno, tutte le connessioni e i controlli possibili. Economico ( Whareouse deals, ma con tutti gli accessori presenti, contrariamente alla descrizione!). Le altre casse del mio impianto 7.1 sono della stessa serie (tranne le due frontali). Soddisfatto.

Aunque se trate de un subwoofer de 10", este Wharfi es más potente que otros de la competencia que presumen ser de 12" y tiene la ventaja de que sus dimensiones reducidas permiten colocarlo en casi cualquier sitio de la estancia. Va genial con la música en estéreo y se ha convertido en el complemento ideal de mis Q-Acoustics 2050i haciendo que el sonido tenga más cuerpo y pegada. En cine también responde bien con un sonido enérgico a la vez que cálido y agradable, y las películas ahora suenan mejor que nunca. Me gusta bastante más que el Magnat Monitor Supreme Sub 302 que también probé. Por ponerle alguna pega, decir que los conectores rojos y negros de entrada de los altavoces se giran más allá de su tope si se aprietan demasiado, por lo que podrían dar problemas si se trastean con frecuencia... aunque para evitarlo se pueden usar conectores de banana y problema resuelto. Un saludo... ;-)

Es un Subwoofer que suena lo justo y hace que los graves se integren de manera natural con el resto de altavoces. Sonido limpio y de mucha calidad.
