Speaker Grills

Your Sapphire XLs are supplied with cloth covered grills which enhance the appearance of your speakers and provide some protection for the drive units. To protect the drivers we recommend leaving the grills in place most of the time. However, for the most critical listening we suggest removing the grills.

Positioning the Sapphire XLs

As mentioned, the proper placement of speakers in your room will easily improve the sound. Because all of our rooms and tastes are different, it is impossible to specify a “correct” placement. Instead, let us present you with some acoustical facts, then you can optimize placement in your room.

It helps to visualize sound waves as behaving very much like water waves. The sound we hear is made up of two types of waves. Direct sound waves come right from the speaker and are not changed in any way. Reflected waves come to us after bouncing (diffracting) off the speaker enclosure itself, or walls, ceiling, floor or furniture. If you want to see how much these reflected waves affect the sound, move your speakers outside and hear the difference.

Sound waves come in different lengths; the lower the note, the longer the wave. Extreme low frequencies such as the lowest organ pedal notes are over 60 feet long! If your room is not big enough, the wave can’t develop fully. But the biggest problem with bass notes is the phenomenon we call standing waves. In effect the waves more or less “pile up”. This creates big peaks and dips in the bass response. If you put a certain frequency through the speakers, you can usually walk around the room and find places where it is very loud, and places where you perceive virtually nothing.

Just as the room affects the bass response, so it affects the mid-treble sound of the system. In the mid-treble range, the sound waves are shorter and have peaks and dips, most of the affects (peaks and dips) occur from enclosure edges, furniture, walls, or the floor. Sapphire XLs exhibit the deepest image when placed away from walls and furniture. The shorter wavelengths of the mids and highs are more easily absorbed than the longer wavelengths of low frequencies. This is why a bare room sounds so harsh compared to a room with a lot of stuffed furniture, carpets, drapes, etc.

An ideal setup for sound would be achieved if you could:

∙Choose a room with width, height and length dimensions that are not multiples of each other. (A cube would be the worst!) Good numbers might be something like, height = 8 feet, width = 15 feet, and length = 26 feet.

∙Choose a room that has an irregular shape, non-parallel walls cut down on standing waves.

∙Place the speakers so that the woofer cones are at irregular distances to the floor, walls and ceiling. This can be difficult. Use a tape to measure the distance from the center of the woofer to the room boundaries. Move the woofers around till you have cut down on the number of related distances. (You don’t want distances like 12 and 24”, but more like 12 and 22”). Use the distance from the woofer to the boundaries to increase or decrease bass output. Sticking the speaker in the corner or close to walls will give more bass output than putting the speaker out into the room. You can use this to get the best balance between bass output and upper range output.

∙Use absorbent materials to help smooth upper-range response and improve transient response and clarity. Why? Let’s take the sound of a bell for example. First you will hear the direct sound from the speaker. But some of that sound bounces from wall-to-wall, ceiling-to-floor, off furniture, etc. before it reaches your ears milliseconds later. Because the time difference is short, you don’t hear an echo, but the sound of the bell is stretched out from something like a “ding” to a “ddiiinngg”. Some speaker engineers have begun to realize this and are addressing the problem in their latest designs. This is why we are now seeing very directional designs. This controlled directionality increases the amount of direct sound in proportion to reflected sound.

Sapphire XLs specifications

Sapphire Audio has made significant strides in the audio industry with its latest release, the Sapphire XLs. These high-performance speakers are engineered to meet the demands of audiophiles and casual listeners alike, providing a stellar audio experience characterized by clarity, depth, and precision.

One of the standout features of the Sapphire XLs is their innovative driver technology. The speakers utilize a combination of high-performance woofers and tweeters. The woofers are designed to handle lower frequencies with remarkable efficiency, providing robust bass without distortion. This makes them ideal for various types of music, from classical compositions to modern electronic tracks. The accompanying tweeters ensure that higher frequencies are rendered with crisp detail, allowing vocals and instrumentals to shine. This dual-driver configuration creates a well-balanced sound profile that enhances any listening experience.

Another key characteristic of the Sapphire XLs is their advanced acoustic engineering. The speakers are built with a finely-tuned bass port system, which enhances the low-end response while minimizing unwanted resonance. The result is a tighter, more articulate bass that complements the overall sound signature without overshadowing other elements.

In terms of connectivity, Sapphire Audio has equipped the XLs with versatile input options. The speakers support both wired and wireless connections, featuring Bluetooth capabilities for seamless pairing with smartphones, tablets, and computers. This flexibility allows users to enjoy high-quality sound without the hassle of cables, making the Sapphire XLs an excellent choice for modern audio setups.

Durability and design are also significant considerations in the Sapphire XLs. The speakers are constructed from premium materials, ensuring longevity while maintaining an aesthetically pleasing appearance. With sleek lines and a contemporary finish, they can easily blend into any décor, whether in a home theater or a casual living space.

Sapphire Audio's commitment to sound accuracy is evident in the meticulous calibration of each speaker, which guarantees consistent performance across different environments. The Sapphire XLs also come with customizable EQ settings, allowing users to tweak the sound profile to their personal preferences, further enhancing the listening experience.

In conclusion, the Sapphire XLs stand out in the competitive audio market due to their exceptional sound quality, innovative features, and thoughtful design. Whether you are an audiophile seeking detail-oriented sound or someone looking to elevate their everyday audio experience, the Sapphire XLs deliver a remarkable combination of performance and style.
