Monitor Audio Gold 50 Bookshelf Speakers


Two-Way Speaker Design:
  • The Monitor Audio Gold series 50 bookshelf loudspeaker employs a two-way driver design with a single C-CAM ribbon tweeter and one 5.5" C-CAM/RST midrange/midbass woofer.
  • The midrange/midbass driver exhibits the low frequency extension and power handling of a much larger driver, while the C-CAM ribbon tweeter produces high frequencies (up to 60kHz) well beyond conventional domed tweeters.
C-CAM Technology:
  • C-CAM driver technology is used throughout the Gold series 50 bookshelf loudspeaker, providing coherent tonal balance and sonic signature across the entering audio frequency spectrum.
C-CAM Ribbon Tweeter:
  • Monitor Audio's proprietary ribbon tweeter design uses an ultra-thin sandwich of C-CAM alloy suspended in a powerful transverse magnetic field of high energy NeFeB rare earth magnets.
  • The ribbon serves as both voice coil and radiating diaphragm, with every part of the ribbon driven directly and simultaneously without energy storage.
  • Having a mass of just 18mg, its diaphragm is able to start and stop in an instant, producing a transient response capable of defining the leading edge and natural harmonic resonance of complex musical sounds.
  • Specified to reach ultra-high frequencies, this ribbon tweeter will reproduce with ease every last nuance and detail from vinyl, CD, DVD Audio, and SACD, together with the wider bandwidth of Blu-ray or high resolution digital audio.
C-CAM Cone Woofer:
  • Ceramic-Coated Aluminum/Magnesium is a material originally developed by the aerospace industry for jet engine components.
  • Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency.
  • In manufacture, aluminum/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness.
  • Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.
  • Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion.
  • C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range.
RST (Rigid Surface Technology):
  • The Gold series bookshelf speaker combines Rigid Surface Technology (RST) with its C-CAM cone woofer design for a stronger, lighter weight cone.
  • The Rigid Surface Technology (RST) cone profile was inspired by the Japanese art of Origami, which demonstrates how a very light material (like paper) can be strengthened and made more rigid by making small and precise folds on it surface.
  • Developed and perfect using sophisticated computer modeling (Finite Element Analysis), the Silver series midbass drivers have been strengthened by a pattern of dimples.
  • RST significantly increases cone rigidity, allowing the radiating surfaces to resist mechanical bending forces, which can twist the shape of conventional driver cones to produce distorted sound.
  • The strengthening effect of RST means that Monitor Audio can use thinner, lighter and more responsive C-CAM cones which provide speed and accuracy while offering greatly reduced distortion.
  • The RST patterns also help to displace standing waves that can propagate on the cone's surface.
Single Through-Bolt Mount:
  • The tweeter and woofer are fixed to the cabinet with single through-bolt driver fixing mounts.
  • This single-through-bolt mount design provides mechanical de-coupling and enhanced midband clarity and resolution.
  • The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
MDF Curved Enclosure w/ Magnetic Grille:
  • The G50 employs a MDF enclosure for accurate, uncolored sound.
  • Rigid 20mm MDF construction is used throughout the enclosure with radial and cross-bracing techniques for high rigidity and low cabinet coloration.
  • In addition, the curved cabinet profile aids in increased rigidity and reduced internal standing waves.
  • In addition, the bookshelf speaker comes with a magnetic grille.
HiVe II Bass Reflex Port:
  • The G50 uses a bass reflex cabinet (rear firing port) with Monitor Audio's HiVe II port design for greater efficiency and bigger bass response from a slim bookshelf speaker.
  • The HiVe II bass reflex port is shaped to have the same effect on airflow as a gun-barrel on a bullet.
  • Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently, for a faster more dynamic bass response.
  • If the bass is too boomy, you can insert the included foam port plug into the speaker's rear-firing port to tighten and lessen the bass.
  • High Quality Crossover & Wiring: The G50 uses a high quality crossover with premium grade polypropylene film capacitors.
  • The speaker also utilizes "Pureflow" silver plated OFC copper internal cabling.
Dual Gold-Plated Binding Posts:
  • The bookshelf loudspeaker has two sets of gold-plated binding posts connected by wire-jumpers.
  • The gold-plated binding posts will accept bare wire (up to 10AWG), pin connectors, & banana plugs (single only). Using the dual posts, you can bi-wire or bi-amp the speaker.
  • Bi-wiring or bi-amping the speaker provides improved bass & treble performance.
  • If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).
  • Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers.
  • Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
  • Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion.
  • We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.
Mounting Options:
  • The Gold series bookshelf loudspeaker comes with self-adhesive rubber feet to help secure it in place to prevent slippage and vibration.
  • The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM41B, sold separately) can be used to wall mount the speaker.
