Audio engineers and professional studios in search of a high-powered studio reference monitor will be impressed with the single, red PSI Audio A25-M, the company's flagship main and mid-field studio reference monitor designed to be tonally balanced; with high-resolution detail and an efficient transient response for precision accuracy in surround setups and stereo studio monitoring applications. The tri-amplifier delivers 170W to the 10.2" woofer, 80W to the mid-driver, and 50W to the 3.9" tweeter, which combine to provide a frequency tolerance of 38 Hz to 20 kHz (+1.3 dB) at an SPL of 124 dB per pair. The tweeter is handcrafted in-house to ensure performance and accuracy.

The amplifier output also features AOI output stages and includes a protection circuit, which can be monitored via the red LED on the front panel. The active crossover with integrated CPR delivers an impulse behavior with accurate stereo imaging. The crossover is also optimized for maximum phase coherence, projecting a wide horizontal and vertical listening area. The electronics are housed in a unit that is mechanically isolated from the speaker cabinet to avoid resonance at high sound-pressure levels.

The rear panel offers a balanced XLR input and features a volume control and a roll-off control for optimizing the low frequencies for standalone use or when using an optional subwoofer. The mid-high section can be turned 90°, allowing for the speaker to be placed in a horizontal position, while maintaining proper dispersion. The PSI Audio A25-M includes a power cord, anti-slippage stickers, and an individual frequency-response diagram.

• Compatible with industry-standard mounting systems
• Amplifier unit acoustically uncoupled from speaker cabinet
• Protection circuits with overload indicator
• True balanced input
• Designed for stereo and multichannel monitoring
• Magnetically shielded for use near video monitors

The AOI is made up of a system that detects the movement of the membrane and the coil as well as a filtered counteraction. This is then tuned to achieve the ideal dampening rate for each frequency

The ALG is used in all regular 2-way and 3-way PSI Audio speakers. The shape and dimensions of the waveguide used in PSI Audio's custom tweeter is specially designed to optimize directivity as well as maximize sound-pressure level and extend bandwidth

The CPR system is made up of several all-pass filters, each acting in a specific range. Combined, they create a compensated phase response, which provides a constant group delay that is kept to the bare minimum through the entirely analog technology

The PSC technology enables remote activation and deactivation of the standby mode of your loudspeakers via the signal cable

A: The Mount-It! MI-SB37 Universal Speaker Wall Mounts (Pair) can support up to 55 lb and will accommodate the dimensions of the M-Audio BX5 D3 5" 2-Way 100W Powered Studio Monitor (Single).

Q: 3. Does the Yamaha HS8 need to be connected via XLR?

A: No. In addition to the XLR connector, the HS8 also has a balanced 1/4" input.

Q: 4. Is that the price of the pair?

A: No, the Yamaha HS8 are priced per speaker. Most studio monitors are priced per speaker, unlike home entertainment speakers which are typically priced per pair.

Q: 5. Can this speaker work with 220V ? or are there any switch button 110 to 220V? I want to buy it from Turkey but there is no information about its working voltage...

A: I purchased it as a gift so I don't know.

Q: 6. Do I need an audio box to power yamaha hs8 monitors?

A: The Yamaha HS8 are self powered monitor speakers. You would only need to input a line level audio signal via the available 1/4 or XLR connection on the rear panel.

Q: 7. power supply 110-220v?

A: The Yamaha HS8 powered studio monitors offered in the US operate at 120V only. They do not include a switchable power supply.

Q: 8. Can I get this bundle in the white variant? Not bothered about the woofer colour just the monitors . I know as singles they do come in a white though.

A: The white version is available I checked another reliable dealer but it is on backorder. suggest you call B&H and ask if and when it would be available they will be happy to contact our buyer for you.

Q: 9. Is it 240-110V?

A: No, it is not switchable between 110/240v. You will need a converter to use these overseas.

Q: 10. IS THE HS5 A WIRELESS SPEAKER?

A: The Yamaha HS5 is not a wireless speaker. It requires a line level audio connection via XLR or 1/4 connection.
