KEF Q150 Bookshelf Speaker, Passive, Satin Black

Product Information

What are some of the inherent performance disadvantages? (IE: Not price, having to design it right, etc.) Answer: due to Uni-Q array drivers you can place the KEF Q150 speakers sideways and experience the same audio quality. You can place them on rubber pads and either horizontally or vertically as you like. Parting words The CXA60 and CXA80 have the following inputs: 2 TOSLINK optical and 1 S/PDIF coaxial digital audio inputs, 4 stereo RCA audio inputs, 1 3.5mm audio input, Bluetooth via BT100. For Bluetooth connection you need to buy an additional BT100 Bluetooth Receiver The RP-600M is a fantastic speaker with a lot of bass for its size and a smooth sound that makes you feel like you’re listening to live music in your home.

The "nref" arrow is the center of the coaxial driver as you would look into it. We see that there is a strong sound source below it which has to be the port. Something coming out of that port is combing with the main driver and causing cancellation in the middle (to some extent). The frequency is 1.4 kHz. If we convert that to wavelength we get nearly 12 inches which happens to be the height of the cabinet. So it looks like it is a longitudinal mode of the internal cabinet coming out the port causing that partial cancellation. There’s a lot that can go into power/spl calculations but some rough ball park figures: - the R3s sensitivity spec is 87db/2.83V/1m. So KEF say 1 Watt to one speaker should give you 87dB from 1 metre away. Each doubling of distance away is meant to cause a loss of 6dB. So at 4 metres away 1 Watt would be giving you about 75dB. However the room itself can add 3-6db gain. And if you add another speaker so you have a Left and Right then that’ll be about 3dB more too. What we’re left with is that at 4 metres away the R3s are likely to be giving you at least 80dB (conservatively). With 1 Watt. Of course now you need to factor in headroom and the likely dynamic range of the material you’ll be listening to (how loud is it likely to go?). Each 3db increase from 80dB would need a doubling of wattage. For your use case at the volumes you like I doubt you’ll be troubling double figures that often. With the Bluetooth port, you can play 24-bit/192kHz high-resolution files via PC, Laptop. You can choose the Class 1 or Class 2 mode from the front panel. The balanced XLR connection enhances the audio quality with the original and uncolored sound. In terms of versatility, they offer a wide range of inputs and outputs. The recent models support Bluetooth and USB. there is a slight difference in their connections so you would choose the one which will be compatible with your existing devices.Essentially, this ensures a much dynamic sound range with farther coverage and wider sound dispersion. This effect is followed by the KEF’s proprietary “tangerine” waveguide that provides more gain for lesser power consumption. A simple work around is to use a standard stereo amp and separate the music side and TV side via a speaker switcher such as the Beresford 7220. It all depends on how much stereo music you listen to and how important it is to you. Easier to not have crossover cancellation. (Off topic PM: why no active crossovers at -999dB per tenth of an octave?) Tall chamber option is available for carbon evaporation to avoid sample heating, to improve uniformity for sputtering and to hold taller samples. Multiple stage options

The Q350 has a higher power output, and as such can deliver more powerful sounds. This doesn’t mean its sound quality is any better. It might even reduce quality if you don’t want that much coverage. Carbon fibre insert. Supplied with 2 m C5421 carbon fibre cord. For additional carbon see: Carbon Supplies (below). Flexible Placement: Their design enables easy integration with all home audio setups and room arrangements. Budget and size are the biggest considerations. Whether your stereo speakers will be in your living room, home office or bedroom, it's crucial to see what fits your space – and what you can afford.Are you after a small, affordable pair that can go into the corner of your room? Are you after a large pair of speakers, or have an extensive budget for premium standmounters? Whatever the case, remember to also factor in speaker cables and the demands of the rest of your hi-fi system. They have so much finesse when it comes to delivering extended bass. They sound taut and agile, but also delicate in the way they paint bass textures and resolve low-level information. There's plenty of punch and power, too. The speakers have a slightly forward balance, especially with the clear and expressive midrange, that sounds lively and engaging – but thankfully never too aggressive.As you might have guessed, ELAC’s UB5 is our obvious choice, and they really are hard to beat at their price. That said, both speakers have their advantages, in both design and performance, so we recommend heading to your local stereo shop or setting up both in your own room to let your ears be your guide. They're commonly known as bookshelf speakers, as some are small enough to fit in/on a bookshelf, or even on to desks. But a bookshelf isn't necessarily where you should put them – we would always recommend placing them on dedicated speaker stands to ensure they sound their best. Many of the products on this list, such as the KEF LS50 Meta, clearly demonstrate they deliver their full potential when not shoved into a corner or in a bookshelf. They also feature Laminair– the aerodynamic port which was first developed for the flagship QB-1 studio monitors. This smooths the passage of air exiting the speaker to minimise airflow noise and improve bass definition. However, if you are considering buying some amp, then Sennheiser GSX 1000 and 1200 could be your perfect choice, you can take a deep look. What are the similarities? Aside from that, the rear features two golden prongs to connect a receiver too. The speaker’s output can be fed into an amplifier for varying levels of sound volume.

A 100W or 200W amplifier doesn’t make much of a difference. Just because the power is doubled, doesn’t mean the amp becomes twice as powerful. The 200W amp can play music 3dB louder than the 100W which is almost unnoticeable. The Wharfedale 12.2 is also a fantastic speaker. I'd avoid being tempted by the current Monitor Bronze range. I found them all very disappointing. The Silver 50s (with a subwoofer) or Silver 100s would be worth a listen though. The Dali Spektor 2 is an exciting speaker, but I did not find it particular easy to listen to for long periods of time. The Dali Oberon range is more refined, but still has what to me sounds like a forward, "get up and go" sound. They are impressive speakers, but not especially relaxing to listen to (at least to me), and a little difficult to drive from my recollection. The answer to that question lies in the driver’s size. While both of them use the same Uni-Q driver arrangement, the Q350 uses a larger driver diameter. The sounds output and soundstage are a lot more pronounced than Q150. And this results in a more powerful sound. Another side effect is, the bass gets amplified significantly. This leads to higher dynamicity and better bass propagation. Size Kef Q150CFD-Optimized Port: Delivers tight, distortion-free bass for a rich and nuanced low-frequency response. In speakers, size matters. The larger the speaker, the more space the drivers get to move, and the better the sound. Q350 is slightly bigger than the Q150. Things on which speaker audio depends: Placement
