What is the frequency response of the Guru 12?
The Guru 12 produces sound ranging from approximately 28 Hz to 30 kHz, delivering deep bass and clear highs.
What is the recommended amplifier power for the Guru 12?
The Guru 12 performs best with an amplifier that delivers between 70 and 250 watts RMS per channel, depending on the listening environment.
What about the Guru 12’s impedance, and what does that mean for compatibility with amplifiers?
The nominal impedance is 5 ohms, with a minimum impedance of around 4 ohms; amplifiers must be rated for lower impedances to ensure safe operation.
How do you properly set up the Guru 12?
Place the Guru 12 on or against bookshelves or on special stands, ideally at ear level with a slight toe-in for a wider stereo image.
Is the Guru 12 active or passive, and what does that mean for the connection?
The Guru 12 is a passive speaker with no built-in amplifiers or DSP, which means that external amplification and adjustment are required.
What material is used for the Guru 12’s enclosure, and what are its advantages?
The enclosure is made of MDF combined with steel, featuring a Helmholtz resonator for controlled, distortion-free bass.
What is the driver configuration of the Guru 12?
It features one 125 mm polypropylene woofer/midrange driver and one 19–20.5 mm soft-dome tweeter to deliver clear high frequencies.
What about the Guru 12’s sensitivity, and what does that mean for listening volume?
With a sensitivity of around 87–88 dB (measured at 2.83 V/1 m), the Guru 12 is moderately efficient; lower volumes require less power, but powerful amplification helps with dynamics.
Does the Guru 12 have built-in connectivity such as Bluetooth or Wi-Fi?
No, the Guru 12 does not include wireless connectivity such as Bluetooth or Wi-Fi; all signals must be transmitted via wired connections to an amplifier or other equipment.
How does placement relative to walls affect the sound of the Guru 12?
If the speaker is placed too close to a wall, the bass levels increase (bass boost), but so does the risk of resonance issues; a minimum distance of 20–30 cm from the wall is recommended.
