By Paul White Can speakers of this tiny size deliver anything like the signature Genelec sound? When we asked for a pair of Genelec As for review we knew to expect something small, but when the cardboard box turned up at my studio it was even more diminutive than I expected. And then, when I opened it, I found that almost half the space inside it was packing to support two smaller cardboard boxes, inside which I found polystyrene packing pieces plus a small cardboard box holding the mains cable. When I finally got to the speakers, they each turned out only to be around the size of a pint glass, measuring x x mm and weighing 1. Genelec a Built into the same style of cast-aluminium casing as the larger series monitors, the rear-ported As have a balanced XLR input.

The correct setup. Proper sound. Page 3: Genelec Key Technologies Genelec Key Technologies For over 35 years Genelec has been guided by a single idea — to make perfect active monitors that deliver neutral and accurate sound in every kind of acoustical environment. In our quest to improve all aspects of monitoring quality we continuously develop innovative solutions in driver technologies, electronic circuitry, signal processing, enclosure designs, and materials.
Page 4: What Is A Monitor Selecting the correct monitors Genelec recommends monitors based on typical listening distances and sound pressure levels. A matching subwoofer exists for every monitor. Refer to our online selection tools or ask your local dealer or distributor for detailed advice.
Here are Page 5: Identifying Your Listening Area Identifying your listening area Divide your room into three equal-sized areas; front, centre and rear. For music productions place your listening setup in the front area.
Each monitor should be aimed towards the listening position. Page 6 Find the left-right symmetry axis of your room.
Place the listening setup symmetrically in the left-right direction. Placing the monitors higher with a slight tilt will minimise floor reflections. Page 7 Placement suggestions for a 5. The sound level at the listener increases when reflected sound is in phase with the direct sound. The sound level decreases when the reflected sound is out of phase with the direct sound. If the room surfaces have not been designed to diffract the sound energy, most of the reflected sound energy leaves the reflecting wall in the same angle as it arrived to the wall.
Page 9: Back Wall Cancellation these frequencies appear to be missing. Moving the listening location can solve the problem. Typically the listening location is moved forward or backward. The most accurate stereo imaging can be achieved when the reflections are similar for the left and the right monitor in a stereo pair.
This can be achieved by maintaining the same distance to the nearest side wall and the wall behind the monitor, placing the left and right monitors to the same height in the room, and placing the listening location symmetrically in the room in the left-right direction. Using a single subwoofer, a placement along the front wall, slightly off-centre from the room middle axis could be recommended.
Page 11 Genelec active series subwoofers have a crossover filter set to 85 Hz. The subwoofer reproduces the frequencies lower than 85 Hz. Higher frequencies are reproduced by the monitors.
Page 12 Post-production facility applications In certain applications, such as large post-production studios, subwoofer Screen placement along the front wall is not recommended as this places the subwoofer very far from the listening position, and the subwoofer frequency response will not be flat. In these cases, we recommended locating the subwoofer close to the main monitor setup along the side Page Calibration Results in a lack of bass in the All Genelec active monitoring systems have room response adjustments to compensate for room influences and retrieve a flat frequency response at the listening position.
Page 14 First set the measurement microphone at the ear height in the listening position typical height: 1. Ensure that monitors are at correct distances and heights. Take a frequency response measurement. Analyse the measurement results and adjust tone control DIP switches to retrieve a flat and balanced frequency response for each monitor. Some Genelec monitors have a desktop control DIP switch compensating for this boost.
Page Acoustic Treatments Acoustic treatments Monitor calibration alone helps but may not be sufficient to resolve room acoustic problems. Audio production rooms are designed for monitoring and should receive adequate acoustic treatments to allow quality monitoring.
Several room acoustic improvements are suggested here. However, using services of a professional consultant is highly recommended. Page 17 First order reflections can have high level while subsequent reflections become smaller. Control room design minimizes the first order reflection level reaching the listening area. Reflections arriving very soon after the direct sound from the monitor are called early reflections.
One aim of control room design is to reduce or eliminate early reflections, having mainly the direct sound from the monitors reaching the listening area. Page Room Acoustics Improvements Room acoustics improvements Several acoustic improvements can be made in a typical rectangular room where an audio monitoring setup is installed.
Here are a few suggestions. Page 19 Cut the room front corners at 30 degree angle using high-mass materials concrete, bricks, multi layered gypsum board, etc. In case building materials have medium mass, be sure to fill the empty space behind these walls with mineral wool.
Use a combination of absorption and diffusion on the side wall surfaces. Note that thin layers of porous absorbers only reduce HF reflections.
