Product Description
Dali Phantom H-60R in-wall speaker is a rectangular speaker with a good balance between size and performance. This a no-compromise speaker that can be used as front or rear channels in a multi-channel system, or alternatively can replace replace bookshelf or small floorstanding speakers in a stereo system, while offering close performance. In fact, edge diffraction is less than with traditional speakers, and in many cases wall mounting should improve impulse response as well as providing a smooth midrange. The rigid baffle should also help with reducing resonance. The woofer is a high-excursion type which should offer punchy bass. Power handling is 150 watts.
Wood fibre cone for a believable soundstage
The H-60R has a wood fibre cone, which is chosen as it should deliver a believable soundstage with lots of detail and little colouration. The Phantom is optimised to deliver powerful bass with it’s large magnet system and efficient moving system. Additionally, the cones are long throw, enabling more air to be moved. When installed properly, this speaker should sound warm and full with coherent bass, a precise midrange and no loss of detail.
Soft dome tweeter
The soft dome tweeter is made of a lightweight weave fabric that has been chosen for good performance. The magnet motor system should provide accuracy as well as detail in the high frequencies. The dome is placed close to the front plate. As a result, the frequency response is increased as well as the dispersion, which should help integration with the woofer.
Speaker Crossovers
To prevent overloading two and three-way speakers use crossover networks. These are essentially filers made from capacitors and inductors. A tweeter would overload if fed the full audio signal, as a result a high pass filter is used to cut off the bass at the crossover frequency. The crossover frequency for tweeters in usually from 2 to 4Khz. Some speakers also have an adjustable crossover.
Low resonance baffle
The H-60R has a low resonance MDF baffle. This provides a solid bass for the drivers and helps to reduce colouration. The baffle also has thick and stiff outer trim that makes a better connection with the wall. This results in less resonance and distortion.
Speaker Construction
The H-60R shares some characteristics common to most speakers. The main part of a speaker is the basket. This holds the cone and magnet system. The cone, made of wood fibre with the Phantom range, is also known as the diaphragm. This is the part that moves air and makes the sound. Next comes the voice coil, which is wound around a circular former that fits in a circular slot in the magnet.
When an electric current or audio signal is passed through the coil, the coil is caused to move. Secondly, the spider is used to hold the cone in place and ensure that it returns to its starting position. Finally, a dust cap is used to prevent debris from falling into the gap and causing a scraping noise.
Magnets nowadays are of the permanent type. However, in the past, they were electromagnets made from a coil of wire. These were energized by the mains supply, and doubled up as filter chokes, to reduce any possible power supply hum.
Speaker impedance
Speaker impedance ranges from 4 to 15 Ohms and is a measure of resistance at a certain frequency. In fact is made up of a mixture of resistance, capacitance and inductance. Speaker coils have inductance as well as DC resistance. The impedance varies with frequency and this characteristic is used to make speaker crossovers which act as filters at audio frequencies. Additionally, the higher the impedance, the less power is delivered to the speaker. That is why power is quoted as 150 Watts into 8 Ohms and the like. Like many other in-ceiling and in-wall speakers, the Dali Phantom H-60R is designed to be easily driven by a wide range of amplifiers.
