Features for the 6MBX44 include a proprietary four twin spoke cast-aluminum frame, enhanced voice coil cooling, curvilinear waterproof paper cone and inverted paper dust cap, and a neodymium ring magnet. Features for the 8MBX51 are fairly impressive. The MR13P-4 is built on a cosmetically attractive six-spoke frame that has a minimal reflective footprint behind the cone to reduce reflections and a completely open area beneath the spider mounting shelf for enhanced cooling— both highly desirable attributes.

This is not surprising. The output of this op-amp is back-fed into the secondary of an audio output transformer, generating high voltage AC V at 40 kHz. This audooxpress of Voice Coil Test Bench characterizes the 6.

This article was originally published in Voice Coil, October In over 30 years of designing loudspeakers, I have found the following measurements taken as a group provide the strongest predictor of loudspeaker preference available to us today.

Erno Borbely shares with us his all-FET audio amplifier design.

Auidoxpress, two pre-amplifiers are used with a battery powered high voltage supply. I received a home audio 6. Each product in this line incorporates proprietary stamped steel frame with a thin mounting lip that enables front mounting without audioxpresss the driver surface mountedhigh relative XMAX, with paper cones for the DS series and aluminum cones for the DSA series.

That’s what you normally get with a quality design, but to achieve it, the author shares the complete concept, power requirements, circuit topology, construction and testing of this single-ended amp The original Satori MW16R, while looking cosmetically similar to the Audioxpresss Illuminator 18WU series, was a well-designed driver that has established itself as a true high-end home audio competitor.

This article was originally published in audioXpress, May InKirk Elliott shared his take on the design, transforming the stock Champ into a quieter, safer, and more reliable studio amplifier. All items in category Project Articles. This article was originally published in audioXpress, June This circuit enables the full galvanic isolation of sound frequency signals with optical transmission in excellent quality, eliminating interference.

ETC of low-pass filter with different corner frequencies. Bruce Brown explains his successful method of rebuilding a vintage W-7 tube amplifier from Heathkit. The Audio Voice Newsletter. When we connect audio components, interference may occur from various power and signal grounds. The project started with a clean sheet, looking to address potentiometer design with a quality that rivaled existing designs while maintaining a reasonable cost.

Here is a simple portable device from George Ntanavaras that can help answer the question about peak voltage and peak current requirements and whether or not your power amplifier audioxpgess capable of driving your loudspeaker without clipping.
