Perlisten loudspeakers may look pretty conventional, but there's a whole load of technology packed into them. This page explains their design concept, and breaks down the features of the loudspeaker range that not only make them unique for movie soundtrack reproduction, but also for music as well.

Perlisten DPC array,

At the heart of every Perlisten loudspeakers is the DPC array - Directivity Pattern Control, provides controlled dispersion in any type of room, and benefits music and home theatre alike.

THX Dominus rated,

The DPC array combines three dome drivers in arranged in a vertical array - all 26mm silk domes for the Reference Series, and 28mm beryllium domes for the Signature Series. The DPC array accounts for all but the lowest 1,000Hz or so of the signal you're listening to, so around 95% of the frequency range of the loudspeaker is handled by the DPC array. This in turn means that this vast range is carefully dispersion controlled by the DPC to provide an in-room response that is focused more on the listening position and less on the room boundaries and any negative high frequency reflections, resulting in reduced necessity for potentially invasive digital room corrections. As the DPC array is used in all models, it provides the same dispersion characteristics and performance throughout the range, so you don't have to worry about mixing and matching different models for your ideal set up.

 

The centre dome provides higher frequencies from around 4.4kHz upwards, and is set into a waveguide that controls vertical and horizontal dispersion. This vastly reduces high frequency reflections from floors and ceilings, and strikes a balance between providing a wide soundstage without bouncing too much high frequencies off the side walls. This makes Perlisten loudspeakers very room friendly, even in the most reflective rooms, and certainly far more so than conventionally speaker designs.  

 

The two flanking domes cover midrange between around 1.1kHz to 4.4kHz (varies slightly depending on the model). At normal listening distances, one midrange dome either side of the HF unit provides a more "point source" sound reproduction - something those who are familiar with the little audio company's loudspeaker ranges will know that we are extremely keen on. Using smaller drive units for midrange frequencies provides a more accurate reproduction, resulting in a faster, more vivid midrange, void of the colorations that larger, heavier midrange cones can introduce. 

The end result is numerous benefits for movies and music that many other speakers just can't match. It allows many of the designs to achieve a THX Dominus rating - the first Dominus rated loudspeakers in the world - able to provide continuous 85dB output and 105dB peaks in a 184 cubic metre room at a seating distance of 6 metres! That's around twice the capabilities of THX Ultra. Most domestic UK spaces are smaller, but it's nice to know that a Dominus rated Perlisten loudspeaker will handle anything you throw at in a smaller space...

THX Dominus capabilities,

The bookshelf and surround speakers of the range are sealed cabinets, with the floorstanding models and the monitor offering the option of sealed or ported use. These models are ported downwards, which means their distance from a wall behind them is less important than rear ported loudspeakers that need plenty of space to work properly. It is in this ported mode that they will likely be used for stereo music listening, with bass typically reaching under 30Hz in many rooms for both floorstanders.

The sealed mode is intended more for home theatre use, alongside a subwoofer or two. Bass is naturally more restricted, but tighter, more detailed, and more even in response. THX recommends an 80Hz crossover point between the subwoofer and speakers, and it is in this mode that Perlisten loudspeakers are THX Dominus rated - ported, they are THX Ultra rated. Of course, this sealed mode could also be utilised in a 2.1 audio system, particularly in more awkward or bassy sounding rooms.
