Frequently Asked Questions about SA70

What is the power rating of the SA70 midrange driver?

The Rebec SA70 midrange driver has a nominal power rating of 25 watts and reaches a maximum power of 50 watts. These power specifications make it an excellent choice for those seeking a midrange driver with stable and reliable power. With these power values, the SA70 ensures that it can be used in a variety of application scenarios, whether in a simple home audio system or as part of a more complex automotive sound system. The 4-ohm impedance helps ensure efficient power consumption from the connected audio electronics.

What are the dimensions of the Rebec SA70?

The Rebec SA70 has dimensions of 69 mm in width, 71 mm in depth, and 83 mm in height. These compact measurements make it a perfect choice for installation in various applications, whether in a car or in a home audio system. When placing and checking compatibility with other components, it is important to know the exact measurements to ensure a smooth installation. Especially when installing in existing speaker systems, the correct sizing can be crucial to avoid unnecessary adjustments.

What frequency range does the SA70 midrange driver cover?

The Rebec SA70 midrange driver covers a frequency range of 160 Hz to 20 kHz. This frequency range allows the speaker to reproduce both low and high tones accurately, providing a comprehensive soundstage for detailed music playback. Such a frequency range is particularly important for midrange tones, which round out the sound image and ensure balanced audio performance. In the field of audio technology, the extended frequency range of the SA70 is an indicator of its versatility and ability to reproduce music pieces faithfully.

What is the sensitivity of the Rebec SA70?

The SA70 midrange driver from Rebec has a sensitivity of 89 dB. This sensitivity is crucial as it describes the ratio of input voltage to output sound power. A higher dB value can produce a greater volume at the same input power, making the SA70 particularly efficient. In practical applications, this means you can operate this midrange driver with decent sound pressure without extremely high amplifier power, making it perfect for low-power amplifier solutions or energy-saving music listening.

What impedance does the SA70 midrange driver have and why is it important?

The SA70 midrange driver has an impedance of 4 ohms. Impedance is a key aspect in audio electronics as it measures the resistance the speaker builds against the flow of current. A lower impedance means that the speaker can draw more current at the same voltage level, which can result in corresponding sound pressure. For users, it is important to ensure that the impedance of the speakers is compatible with that of the amplifier to achieve optimal performance and avoid potential damage to the audio hardware.

What features does the voice coil of the SA70 have?

The SA70 midrange driver from Rebec features a 20 mm voice coil. The voice coil plays a crucial role in the performance of a speaker as it is responsible for the movement of the diaphragm that produces sound. A 20 mm coil offers a balanced combination of flexibility and robustness, contributing to precise music reproduction. This is particularly advantageous when you expect detailed and clear sound reproduction across the entire frequency range. A well-sized voice coil is essential for distortion-free sound.

Is the SA70 compatible with common car brands?

The compatibility of the SA70 midrange driver with common car brands can be ensured by its compact dimensions of 69 mm x 71 mm x 83 mm, making it suitable for a variety of applications and vehicle installations. When installing, it is important to check the mounting openings and space conditions in the vehicle to ensure that the speaker fits well and integrates into the existing acoustic structure. The SA70 is ideally sized for custom sound projects in vehicles.

How do I optimally install the Rebec SA70?

When installing the Rebec SA70, precise placement is crucial to ensure the best sound quality. Due to its compact size of 69*71*83 mm, it can be easily integrated into various environments. Make sure there is enough space to achieve optimal sound distribution. Use appropriate mounts and installation materials that minimize vibrations. Ensure that the electrical connections are secure and tight to avoid signal interference. The correct alignment of the midrange driver can significantly improve sound quality.

What role do the Thiele-Small parameters play in the SA70?

Although the specific Thiele-Small parameters (TSP) for the SA70 are not provided, they are generally crucial for understanding speaker characteristics such as resonance frequency and electrical equivalent. These parameters assist in optimizing the speaker enclosure and tuning for specific audio conditions. Typically, TSP allows for precise planning and adjustment of speaker systems to achieve the desired acoustic performance. Note that knowledge of TSPs is useful in developing custom audio applications, especially when aiming for a specific sound profile.

Why is the frequency response of 160 Hz to 20 kHz important for the SA70?

A frequency response of 160 Hz to 20 kHz, as seen in the Rebec SA70 midrange driver, is significant because it covers a comprehensive range of mid to high frequencies, which is essential for detail accuracy and sound clarity. Such a frequency response ensures that all musical nuances are reproduced, from deep baritone voices to the highest sopranos and instrumental tones. For sound enthusiasts, this means an immersive and precise listening experience that is optimal for both music and voice-intensive media content.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
