Harley52The Trilogy is not omni in any sense, except in the Bass region where wavelengths are longer. It has a narrower and more consistent pattern than typical audiophile speakers. It is important to maintain the same dispersion angle across the spectrum from the midrange and up in order to create a situation where the frequency response shape reflecting off the room boundaries is similar to the response coming directly from the speaker. Meaning, that your brain does not want to sum different responses between the direct field and reflected field. Narrower dispersion reduces room interaction and allows more nearly a "near-field" listening experience. Fortunately, Duke has been promoting the importance of this for many years.Most home audiophile speakers have a dispersion pattern that is too wide and not at all consistent with frequency. A good example of a correctly designed speaker from this viewpoint would be the TAD Reference 1. The Trilogy meets this criteria as well. Exposed dome and ribbon speakers are usually very room dependent for this reason. Andrew Jones and I both come from the pro industry, where controlled directivity as a technical feature is valued at near the top of the list when developing the design platform. A major reason why an omni speaker, like the MBL can sound so good, is while the room is excited (bad), the consistency of radiated energy per cubic centimeter is very high (good). But then they are highly dependent on good room acoustics.Therefore, a coaxial design such as we are using is a very good design solution, allowing a point source from 100Hz up along with good pattern control. Obviously, the driver design and system execution will ultimately determine the success of the design, but this is the best known platform, in my view. In the Trilogy, the coaxial unit is also open baffle, affording a very natural reproduction that breathes and has very low coloration.Regarding the sweet-spot question. The short answer is that a small but optimum point for stereo imaging is just the nature of stereo. The best image focus will usually have the smallest listening spot. Very similar to a photo lens, where a cheap, auto-focus camera is more forgiving than a precision manual adjust lens, but delivers a lower quality result.Clayton ShawSpatial www.spatialcomputer.com
Wow, very interested. Considering a very no BS gear sale to cover $1500
What are you thinking of selling?
I noticed Underwood mentioned an T2 model. Any info @ the T2 ?
How far must this speaker be placed from walls?
I can't believe these got past me. Ok, dang, add Spatial to my list for system 2.
To my eyes they look pretty WAF compatible though Tried Spatial's wires and IC's last summer and they make nice stuff.
