There is a big difference between a large high mass highly reactive speaker cabinet in comparison to an amplifier, power conditioner or any electronic component. In many situations the 1.5" AP will sound better than the two inch version however the 2" AP will clearly sound better in other applications.
Loudspeakers produce much more energy and vibration increasing resonance that affects the performance of each driver in combination with the enclosure. The two inch audio points were supplied for the larger Revel which has a lot more mass and surface area compared to an electronics chassis and smaller speaker designs. In this case we added more brass weight in order to attract the heavier amplitudes of resonance and unwanted noise that forms up on a dense speaker chassis. In this particular application the two inch Audio Points would clearly outperform the smaller version.
The Audio Points were provided as a quick fix/improvement and will eventually be traded back when the larger Sistrum Apprentice XL becomes available this fall.
Please remember it is not fair to compare an Audio Point performance and functionality to any Sistrum Platform design as the platforms are designed with a totally different geometry and present a much larger area of reactance. Tom. Star Sound Technology
