Mids (midrange)

The 160mm midrange driver provides a rich, warm, and lifelike midrange reproduction. Vocals and instruments in this frequency range are presented with excellent accuracy and detail, giving a sense of realism to the music. In addition, the midrange is well-balanced and never overpowers the other frequencies, ensuring а coherent and cohesive sound signature.

Lows (bass)

Equipped with dual 160mm bass drivers, it delivers a powerful and controlled low-end performance. The bass is tight, punchy, and extends deep, providing a solid foundation for the overall sound. Despite its authority, the bass remains well-integrated with the mids and highs, preventing muddiness or overwhelming boominess.

Setup and Integration

Ideal room size

Speaker placement recommendations

To optimize the sound quality and imaging of the Borea BR09, it is recommended to place the speakers at least 2-3 feet away from the rear and side walls. Ideally, the speakers should be spaced 6-10 feet apart, and slightly toed-in towards the listening position. Experimenting with the distance and angle mаy help you achieve the desired soundstage and imaging. Additionally, ensure the tweeters are seated at ear level for optimal high-frequency performance.

Some popular amplifier brands include Marantz, Denon, Yamaha, and NAD.

While the Q750 delivers a refined and detailed sound, it may not offer the same level of bass extension аnd impact as the Borea BR09.

For those who prefer a more aggressive and dynamic sound, the RP-8000F could be an attractive option.

ELAC Debut F6.2

The ELAC Debut F6.2 is a budget-friendly option that delivers impressive performance for its price. While the F6.2 offers a well-balanced sound signature and solid bass response, it may lack the refinement and detail in the Borea BR09. However, the F6.2 could be a great choice for those on a tighter budget who still want a high-quality floor-standing speaker.
