Audio Sensibility MA30SG Loudspeaker

Audio Sensibility MA30SG Loudspeaker

We heard the original Mundorf MA30 SG speaker kit at the Toronto Audio show (TAVES) in October 2015.

The original MA30 loudspeaker has received a number of glowing reviews:

Designed to celebrate 30 years of collaboration between German companies Mundorf and Accuton, the MA30 SG speaker kit includes Accuton ceramic woofers, Mundorf air-motion tweeters, and Mundorf crossovers typically found in loudspeakers at ten times the price.

Mundorf Premium Crossover

  • Magico Q1 Crossover (Monitor loudspeaker pair $US26500)

The MA30SG crossover provides an insanely great price/performance. To put this into perspective we compared the MA30SG crossover to the Magico Q1 crossover (built at the Mundorf factory). The Magico Q1 is a premium quality monitor loudspeaker that retails for $US26500.00. Our technician remarked that the Magico Q1 was using lower priced Mundorf Supreme capacitors compared to the MA30SG which includes Mundorf Supreme SilverGoldOil (SGO) and Mundorf EVO SGO capacitors.

The MA30SG Inductors are of similar quality to the Q1 and their use is virtually unheard of in loudspeakers less than $US15000. The MA30SG crossover board is huge and fills 75% of the floor space of the cabinet.

Building a Better Mousetrap

Although the original loudspeakers sounded great, we felt that their was plenty of untapped potential. After the Toronto show we spent considerable time with the TAVES show loudspeakers and did extensive prototyping and testing.

We discovered that the performance of MA30 SG loudspeaker was being hampered by its supporting cast of components.

  • Chinese-made MDF cabinet.
  • Flimsy mounting of drivers.
  • Inefficient plastic binding post mounting system.
  • Conventional internal wiring.
  • Inexpensive internal damping material.
  • Suboptimal loudspeaker stands.

Audio Sensibility has successfully eliminated these bottlenecks to performance. The result is a magical loudspeaker regardless of price.

Computer Aided Speaker Design

For the Audio Sensibility loudspeaker project we needed to design three separate

Sophisticated Cabinet Construction

We have developed a 1” thick dowel-fastened cabinet for maximum rigidity, using the latest 3D CAD Design software.

CNC Machined Aluminum Baffle

The drivers are mounted on a 1” thick mirror-anodized Aluminum speaker baffle. The combined rigidity of the two part cabinet ensures maximum transmission and transparency of sound.

Signature OCC Copper Speaker Cable Inside!

Audio Sensibility’s exclusive cryogenically-treated Teflon/Air dielectric rectangular OCC Copper is used for all internal wiring. This is the same technology used in our Signature OCC Copper speaker cables. The following review in NOVO High End provides highest recommendations.

Internal Speaker Damping Material

Damping materials are used to reduce the effects of panel resonance, diffraction from cabinet edges, and standing waves from internal reflection/reinforcement modes. Most companies use inexpensive materials such as polyester batting for internal damping of loudspeakers.

TWARON® Angel Hair is a speaker cabinet filler for acoustic damping which is produced exclusively for Mundorf. TWARON® Angel Hair absorbs acoustic energy in a more efficient manner than conventional materials used for damping purpose. The material constantly tends to expand and therefore always fills the available space. Therefore a sufficient cabinet filling only requires 3-5 grams per litre. You just need 10 to 20% of the weight of other damping materials.

The low mass of TWARON® Angel Hair provides improvements in music performance compared to conventional damping materials.

  • Increased fine dynamics in the midrange.
  • More “airy” reproduction of voices and instruments.

The cost of TWARON® Angel Hair is 100X the cost of polyester batting but the results are well worth the additional expense.
