Wharfedale Diamond SW150 Subwoofer (Black)

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.

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.

Does the job and pleased with the quality.

Sound, as in one's reaction to it, is a subjective reality. There are technical specs, there are physical laws and limits. Then there's your ears/brain/kit combo/room... and there is mine. Then there is the sound track and the degree to which it has been 'balenced' So all I can say after 30 plus years of working with various sound editors/supervisors/designers is, well good luck with your choices. So given the above all I will say is for the money it's not bad at all. Gives depth to the atmosphere when it's there in the mix, gives boom to the room when Game of Thrones gets off on one and does not make its presence felt when bass notes would never have been mixed high. I set it up as per manual and then set it up in the system as per manual then played three testing sequences ad nauseoum until a tweaked result was achieved that I like. I like? I like to hear it all, full width but behind dialogue and this SW does it. I don't hear buzzing or anything much from it except when the mix demands it. My viewing room it 18x30' with unimpeded walls and fitted carpet and this SW can help fill it. Price? well I blinked before Amazon but in this instance I don't mind and as I have two other Wharfdales still going after 37 years my hopes are high. Accurate? well with a twined line in connection - good enough; it sits in a corner out of my sight line and spreads bass or boom out to the room without rattling the china, less really is more until more means you're watching something big, then she go big. Oh auto switch off don't but that could be my kit.

Affordable good quality subwoofer Quick dispatch from the seller

This sub woofer just works well and enhanced my hifi setup which was good in the first place, although originally lacking a bit of extra bass. I connected it to a 50 year old Yamaha vintage amplifier via the speaker level inputs and after a little tuning, as per the manual advice, it is to my liking. So far I am very pleased with the upgrade.

There are technical reviews of this sub right here on Amazon - take a look at them for specs etc. I'm more concerned with the 'feel' and 'shape' of the sound, the kind of thing that makes your hair stand up on the back of your neck. For the price, this sub is simply incredible. It's perfectly able to deliver a gentle, smooth, buttery caress of bass when required, filling out ever present low tones in Sci-Fi movies or from your favourite bass guitar using band without a hit of grit or roughness to be found. But, when required, it can also smash out a heart racing, chest thumping, ear bashing, punch to the face of full throttle bass extravaganza, like a bit of Hardcore Trance or the opening scene of Quantum of Solace or the Shuttle entry scene in the opening few minutes of the extended version of Avatar (something that brought my old sub to it's knees!) It's big, it's heavy, it's solid and placed correctly and paired with a decent amp it's wonderful to listen to. I paired mine with a Pioneer VSX-922 and a set of small and old (but fantastic) THX certified speakers for a 5.1 surround sound set up. I recently watched Blade Runner for the first time - the opening scene just comes to life, immersing you in amazing audio. I'm the first to admit that I'm just a baby audiophile, not yet interested in the best technical equipment. But I AM obsessed with getting that incredible FEELING that only good audio bring you and this completely fits the bill on that point. I'd go so far as to say that this sub beats anything I've personally heard at this price point - which is probably why I bought one!

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.
