In one of my systems, Zu Druids replaced Silverline speakers, and I had heard the entire Silverline range before making that change. The Silverline speakers each are voiced and hence while there is a family semblance in sound up and down the line, the model-to-model variations are considerable and deliberate. Until I bought my Zu Druids and then also Zu Definitions, I considered Silverline exceptional dynamic driver speakers, with excellent transient consistency, natural tone with good continuity between the drivers, and capable of focused, coherent presentation.
After hearing Zu, all that changed and I couldn't possibly go back to them or any other conventional multi-way speaker with crossovers in the meat of the music.
It's hard to appreciate until you hear the difference, but getting a full-range driver with a signal not passing through a crossover, in a design that avoids the shout and frequency anomalies of prior FRD high efficiency designs, lays bare how much a crossover mangles sound. Also how poorly even well-matched quality drivers mate in terms of tone and uniformity of transient behavior. Zu puts no crossover in the path of the signal from 38 Hz - 12kHz, and of course the main driver is dynamically uniform in its transient behavior through that range. In the Druid, the FRD rolls off naturally and the supertweeter rolls in on a high-pass filter. On the Defintion, the FRDs roll off naturally on the bottom and the active sub-bass array is rolled in on a low pass filter, while the supertweeter rolls in on a simpler network than the Druid. Now, by comparison, even excellent Silverline speakers sound choked, dynamically disjointed, faux-fidelity, untonal and spatially incorrect by comparison.
Every other conventional multi-way speaker suffers the same comparison. It's a one-way street. Once you make the transition to Zu and assimilate the holistic delivery of a music signal through a tonally natural FRD, you cannot go back. You can only move forward when you find something that retains the phase-coherent, frequency accurate, high sensitivity, sparky aliveness of Zu and makes it more accurate and natural still. I haven't heard that from anyone else yet.
So, I can't say about Salk and Tyler. But if they have crossovers in the midrange, where Zu has none, I'd have little hope. On the other hand, if you never hear Zu, the right Silverline will seem to make beautiful music in energetic fashion.
