The Steg SQ 25 speaker<\/strong> is intended for a car audio system. Before choosing where to install it, check three separate measurements: the 44 mm mounting hole diameter, 25 mm mounting depth and 50 mm outer diameter. Each describes a different part of the space the speaker needs. A mounting hole of the right size alone does not establish that the speaker will fit.<\/p>\n

Mounting space and dimensions<\/h2>\n

The mounting hole diameter<\/strong> describes the opening required in the mounting surface. The outer diameter<\/strong> describes the space occupied on the visible side. Allow room for the outer part of the housing between the edge of the hole and any surrounding trim. This matters especially when the proposed position is close to a trim edge or another interior feature.<\/p>\n

Mounting depth<\/strong> concerns the space behind the surface. Check all three areas before installation: the opening, the space around its front edge and the clearance behind it. Measuring only the opening can overlook an obstruction at the front or back.<\/p>\n

Choosing a position in the cabin<\/h2>\n

Assess the proposed position before altering the car\u2019s trim. Look behind the mounting surface for obstructions, and check that the wire can be routed safely once the speaker is secured. At the front, make sure the outer housing will allow the trim to be fitted and will not interfere with moving interior parts.<\/p>\n

If you are installing speakers on both sides, choose similar positions where possible. After installation, listen from the driver\u2019s and passenger\u2019s seats to check whether the sound remains balanced. Before fastening each speaker permanently, hold it against its intended position. This can reveal conflicts with trim or wiring that a measurement of the hole alone would miss.<\/p>\n

Housing and appearance<\/h2>\n

The speaker has a glossy spun aluminium housing<\/strong> and a hexagonal grille<\/strong>. If the installation position leaves the speaker visible in the cabin, consider how these finishes will sit alongside the surrounding interior. The appearance of the housing and grille does not change what the stated mounting dimensions measure.<\/p>\n

Electrical and acoustic information<\/h2>\n

The DC resistance (Re)<\/strong> is 6 ohms. This is an electrical measurement of the speaker, but it is not its nominal impedance. The Re figure alone cannot tell you what amplifier load to assign to the speaker or how to connect it with other speakers.<\/p>\n

Sensitivity<\/strong> is 90 dB when measured at 1 W and a distance of 1 m. Keep those measurement conditions in mind when comparing speakers: sensitivity figures given under different conditions are not directly comparable. Sensitivity also does not state the maximum permissible power.<\/p>\n

The resonant frequency (fs)<\/strong> is 1400 Hz. It describes the speaker\u2019s resonance, but it does not, by itself, determine a suitable crossover setting. Do not treat fs as either a stated frequency range limit or a ready-made filter setting.<\/p>\n

Planning the connections<\/h2>\n

Before selecting an amplifier channel or wiring arrangement, obtain the speaker\u2019s nominal impedance and permissible power rating. Compare those figures with the amplifier\u2019s specified load and power. The information in this description is insufficient to make that decision on its own.<\/p>\n

Check how the wires will connect and run through the particular mounting location. If the connector type or its markings are unclear, identify them before buying connection accessories. When connecting a pair, follow the equipment markings to keep polarity consistent on both sides. Before replacing the trim, check every connection and make sure no wire will be pinched.<\/p>\n

Setting up the sound system<\/h2>\n

Begin listening at a low volume on the amplifier or player, then increase it gradually. If the system has a gain control, adjust it according to the amplifier\u2019s instructions while listening for distortion. If you use a crossover, seek further information about both the speaker and the system before choosing its setting; resonant frequency alone is not enough.<\/p>\n

The balance control lets you listen to the left and right sides separately before returning to your preferred overall balance. If an equaliser is available, start with neutral settings. That makes it easier to hear how the installed system sounds before making adjustments.<\/p>\n

Stereo, home cinema and multi-speaker systems<\/h2>\n

For a car stereo system, first decide which channel will serve each speaker and check the mounting position on both sides. If you plan to use the SQ 25 with other speakers, its dimensions and sensitivity alone cannot show how the complete system will work together. Consider the connections and filtering used for each component.<\/p>\n

Connecting several speakers to one amplifier channel changes the load on that channel. Do not choose such an arrangement without knowing the speakers\u2019 nominal impedance and the load the amplifier permits. If you are considering the SQ 25 for a home cinema system, first check its compatibility with that system\u2019s amplifier, connectors and proposed mounting position. The figures provided here do not establish suitability for a particular home cinema configuration.<\/p>\n

FAQ<\/h2>\n

Is a 44 mm hole enough to ensure the speaker will fit?<\/h3>\n

The hole is only one part of the mounting space. You also need room for the 50 mm outer diameter on the visible side and 25 mm of depth behind the surface.<\/p>\n

Does the 6 ohm DC resistance give the nominal impedance?<\/h3>\n

No. Before connecting the speaker to an amplifier, obtain its nominal impedance and check whether it suits the chosen amplifier channel.<\/p>\n

Is 1400 Hz a crossover setting?<\/h3>\n

No. It is the resonant frequency. Fs alone is insufficient for choosing a filter setting; use additional information about the speaker and the system.<\/p>\n

What does the stated 90 dB sensitivity mean?<\/h3>\n

The value is specified at 1 W and a distance of 1 m. Before comparing it with another speaker\u2019s sensitivity, compare the measurement conditions.<\/p>\n

Is the information provided enough to assess amplifier compatibility?<\/h3>\n

No. You also need the speaker\u2019s nominal impedance and permissible power rating, neither of which is provided in this description. Compare those figures with the requirements of the amplifier you intend to use.<\/p>\n","protected":false},"excerpt":{"rendered":"
