A Learned Second Opinion
Bob actually learned his craft from the early work of Dr. Harry Olson, and from a colleague Leslie Williams, a physicist for whom the math was a walk in the park. Leslie wrote the following after hearing the Amazing Line Source and it bears repeating.
"What counts in a loudspeaker designed for stereo reproduction is the resulting High-Fidelity, be it ‘you-are-there’ or ‘they-are-here.’ High-Fidelity must include accurate frequency and transient response, life-like levels without audible distortion, and realistic portrayal of ambience and imaging.
I have personally made many forays to push the state-of-the-art, both by creating psychoacoustic models that mathematically depict most of Hi-Fi, and also designing and building speakers for music playback for friends. From that, I established that integrating all of the elements from source to brain into a coherent system design is crucial – not just a single component or room or technology. The speaker is the nexus, since it touches more of the system than anything else.
Bob’s Amazing Line Source gives the best Hi-Fi, not because of any single aspect (e.g., line source, tube amps it is driven with, or transducer technology), but because he has done the best system design.
Some of my tech notes from measuring and listening to them for a few days:
The Amazing Line Source is unique in being acoustically transparent to the source with life-like levels and a small horizontal footprint, and…
…seamless both vertically and horizontally in a room.
The midrange double line has a uniform polar pattern over its bandpass
Neither the midrange nor the tweeter line exhibits any chaotic frequency response due to array factors
There are no measurable (let alone, audible) specular reflections
The form factor of the sub acoustically integrates with the room on the floor or wall, in the corner, or under your seat
In consumer speakers, the tweeter is a noticeable bottleneck – but not with The Amazing Line Source
ALL speakers should be either far from, or directly on, the wall. The Amazing Line Source works – even with imaging – for both
No other speaker does both to the necessary extreme in a room. Though… Big professional line arrays may play louder, but they are line arrays, not true line sources. Big difference! …as a designer, listener to live music, and lover of Hi-Fi: I’m jealous."
