Stand Loudspeaker Reviews

A new name to me, West German company MB Quart GmbH is, in fact, the reincarnation of the Peerless loudspeaker company that until 1983 used to be owned by New York–based Electro Audio Dynamics (EAD). The company has been in existence for over 20 years and under either name has an excellent reputation for its drive-unit technology, MB being one of the first manufacturers to offer an OEM metal-dome tweeter. Their 1" titanium-dome unit, for example, was featured in Dick Olsher's Dahlia-Debra DIY design (footnote 1), and I became quite enamored of the effortlessly clean nature of that speaker's treble.

You never know when an idea might hit you, maybe when brushing your teeth, standing in the shower, or stirring the stew.

Have you ever flexed a playing card (or a few) back and forth close to your ear? They generate a little sound. According to MBL company lore, that action and sound sparked the design idea for the original Radialstrahler omnidirectional driver.

What was old is new again. McIntosh Laboratories has been in business long enough that they are able to bring new design thinking, materials, and construction methods to products from their extensive back catalog. Example: McIntosh's first successful loudspeaker, the ML1. The venerable Binghamton, New York, hi-fi company recently released a redesigned "Mk II" version ($12,000/pair, stands included).

In this, McIntosh is not unique; KLH, JBL, Klipsch, and other companies have rethought and reworked vintage products for the current marketplace, employing new approaches and technologies. Think of it as remastering classic hardware.

Some audio experiences stick in your memory. For me, one such was in 1978, which I reminisced about in a 1987 review for Stereophile of the Mission PCM 7000 CD player, Mission 780 Argonaut loudspeaker, and Cyrus Two integrated amplifier. Mission founder Farad Azima (footnote 1) was a driving force in the UK audio scene in the late 1970s, when I was deputy editor of the English magazine Hi-Fi News & Record Review.

Cyrus is the name given to the higher-priced line of loudspeakers made by England's Mission Electronics. The entire Mission loudspeaker line includes six products under the Mission label and three under Cyrus. Mission also manufactures a wide range of electronics and CD players. The company has a long history of audio innovations, both in loudspeaker and electronic design. Among Mission's claimed "firsts" are the first polypropylene-cone drive-unit used in a product (1978), first widespread use of MDF loudspeaker enclosures (1981), and first CD player from a specialist manufacturer. Interestingly, Mission also makes IBM-compatible personal computers.

The $900/pair Cyrus 782 is a two-way design employing dual 7" (175mm) polypropylene-cone woofers and a single ¾" (19mm) fabric-dome tweeter. The drivers are arranged in a D'Appolito configuration to simulate point-source radiation characteristics. Both woofer and tweeter were designed from scratch by Mission. The polypropylene woofer cones include a "mineral loading" that reportedly increases cone rigidity, thus decreasing cone breakup. Additional woofer design features include a shaped pole piece to increase linearity during high cone excursions, rigid steel chassis to reduce driver resonances, and a tight tolerance between the voice-coil and magnet to increase sensitivity.

"A 10" two-way?!?!" I couldn't help gasping in surprise when I unboxed the MoFi Electronics SourcePoint 10 standmounted loudspeakers, which cost $3699/pair.

Some background is in order. Using a large-diameter woofer endows a conventional two-way speaker with potentially high sensitivity and extended low frequencies. However, the large woofer's radiation pattern narrows at the top of its passband, whereas that of a tweeter mounted on a flat baffle is at its widest at the bottom of its passband. Even if the drive units' outputs are well-matched in the speaker's on-axis response, this discontinuity in the speaker's off-axis behavior results in an in-room balance that will sound bright. This is why favorably reviewed two-way designs tend to use a woofer with a 6.5" or even smaller diameter.

When I got these new speakers for review, they were so new that, at the time I unpacked them, no official user manual was included or posted on the manufacturer's website, and the promised matching stands didn't exist. Yet, I have the abiding feeling that I am getting to the party long after it has started. The Mobile Fidelity SourcePoint 8 is the newer, smaller sibling of the SourcePoint 10 reviewed by John Atkinson in Stereophile's February 2023 issue, with a follow-up by Ken Micallef in June.
