Product Features

• Hifi Tower Speakers Design: The speaker is designed to provide a live concert-like experience in your living space. It houses a 0.9″ high-frequency driver that is hermetically sealed and mechanically isolated to protect it from internal resonances caused by the two 5″ mid/bass drivers, ensuring a refined sound.
• Quiet Cabinet Design:
  • The stereo speakers feature Gelcore cabinet construction, which helps in reducing higher frequency noise.
  • The P2P internal bracing further stiffens the cabinet to minimize lower-frequency vibrations. This ensures an improved focus on the stereo image and provides an extended holographic soundstage.
• No Interference:
  • The isolation suspension system is a standout, ensuring that there are no unwanted external or internal vibrations affecting the sound quality.
  • The crossover is placed away from the drivers’ electromagnetic fields to minimize any microphonic pickup.
  • The HPE tube design helps in cutting undesirable standing waves for a precise frequency response.
• Elegant Design:
  • Concept 50 mirrors the sophisticated design and high gloss finish of the Concept 300 and 500 models.
  • The aluminum front baffle plate is a signature of Q Acoustics that has been retained, giving the speaker an iconic look.
  • The floor speaker is available in gloss black, gloss silver, and gloss white finishes.
• Controlled Power:
  • The 5-inch mid/bass and 0.9-inch tweeter drivers are specifically designed for Concept 50 and are integral to the mechanical structure of the cabinet.
  • These drive units are fixed to a stiff 3mm aluminum baffle plate, ensuring the correct acoustic seal and minimizing structural coupling.
  • The tweeter is specially designed to be hermetically sealed and mechanically isolated for reduced distortion and seamless integration.
  • The mid/bass driver voice coil is made larger for increased power handling.
• HPE (Helmholtz Pressure Equalizer) Technology: This innovative technology is used to combat undesirable standing waves that might occur within the speaker’s cabinet design. The technology ensures pressure conversion to velocity, providing a more accurate frequency response.
• Gelcore Technology: Introduced in the original Concept speaker, this technology is designed to handle high-frequency noise. The unique design has a non-setting gel sandwiched between two layers, dissipating high-frequency vibrations into heat for a focused audio performance.
• Isolation Suspension System: This system is a testament to the speaker’s design to minimize any kind of interference, ensuring that the sound output remains pure and unadulterated.
• P2P (Point to Point) Technology: This involves point-to-point cabinet bracing, which aids in sound quality enhancement.
• Bi-wire Cable Terminals: This allows for versatile wiring options for enthusiasts who wish to explore bi-wiring or bi-amping.

These features collectively set the Q Acoustics Concept 50 Floorstanding Speaker apart, emphasizing both its design prowess and commitment to unmatched sound quality.

Additional Features

• Cabinet Technology : Gelcore construction, designed to minimize high-frequency noise.
• Isolation Suspension System : Minimizes unwanted external and internal vibrations.
• P2P Technology : Internal bracing to enhance sound quality.
• Connection : Bi-wire cable terminals for versatile wiring options.
• HPE (Helmholtz Pressure Equalizer) Technology : Designed to eliminate standing waves within the cabinet for improved sound quality.

Product Usage Instructions

• Positioning
  • Place the speakers at least 20-30 cm away from the walls to ensure proper airflow and to prevent sound reflection.
  • If possible, position the speakers so they are equidistant from your primary listening position for an optimal stereo image.
  • Toe in the speakers slightly towards the listening position. This can enhance the stereo imaging.
• Wiring :
  • Use high-quality speaker cables. Ensure that the polarity (+/-) of the cable matches the speaker and amplifier.
  • If bi-wiring, ensure to remove the jumpers from the speaker terminals.
• Volume : Avoid playing the speakers at maximum volume for extended periods to prevent damage to the drivers and to prolong the speaker’s lifespan.

Safety Instructions

• Handling :
  • Lift the speaker with care; they can be heavy and awkward to move.
  • Avoid placing objects on top of the speakers.
• Environment :
  • Avoid placing the speakers in direct sunlight or near heat sources.
  • Do not expose them to moisture or extreme temperatures.
• Power Safety : If using a connected amplifier, always turn it off before connecting or disconnecting cables.
• Children and Pets : Keep the speakers out of reach of children and pets. The drivers, especially tweeters, can be delicate.

Maintenance Instructions

Cleaning :

• Dust the speakers regularly with a soft, lint-free cloth.
• For deeper cleaning, use a slightly damp cloth to wipe the surface, and then dry with a dry cloth. Avoid using chemical cleaners.

Speaker Grilles :

• If removable, take them off gently to avoid damaging the pegs.
• They can be cleaned using a soft brush or a vacuum cleaner set to a low setting.

Cables :

• Regularly check the speaker cables for wear or damage. Replace if necessary.
• Ensure connections remain tight and secure. Loose connections can degrade sound quality and can be a safety hazard.

Inspection :

• Periodically, inspect the speaker units for any visible damage or wear.

Avoid Blocking Ports :

• If your speaker has rear ports, ensure they are not blocked or covered, as this can affect the sound quality.

Spikes and Feet :

• If using spikes, ensure they are tight and regularly check to see if they need re-tightening.
• If the speaker is placed on hardwood or delicate flooring, consider using protective discs or pads under spikes to prevent damage to the floor.
