LOUDSPEAKER
“A 10" two-way?!?!” I couldn’t help gasping in surprise when I unboxed the MoFi Electronics Source-Point 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.
But …
The SourcePoint 10 was designed by Andrew Jones, a well-respected veteran loudspeaker engineer with highly regarded models from KEF, Infinity, Pioneer, TAD, and ELAC in his resumé.1 Andrew, who is now celebrating two years with MoFi, has indeed done something different with his first design for the company.
The SourcePoint 10
The first thing you notice about this speaker is that the sculpted, 2"-thick front baffle has a single, centrally placed drive unit with a 1.25" soft-dome tweeter mounted concentrically at the center of the 10" woofer’s paper-pulp cone. The second thing you notice is that instead of a conventional half-roll rubber surround for the cone, the woofer, which is reflex loaded with twin ports on the rear panel, uses an old-fashioned corrugated surround. The third thing you notice is that this is a large, heavy design for a stand-mount; it measures
