The design lends a lot of interest as the approach is unique. Using a closed couple cavity with a band pass design to create an acoustic crossover of 12db per octave, which in turn lent to a simpler crossover design between the woofer and mid driver. A concentric driver to aid in creating better integration between the tweeter and mid driver. The passive radiator making speaker placement when dealing with boundary walls potentially easier.
A bit of effort went into the design to be a bit more clever than most, especially given the targeted price point, but the commentary thus far indicates further refinement will be required. Its measured characteristics also indicates careful paring. First, it has a rather low efficiency with a specified 85db and measuring a bit lower. The impedance plot isn't benign and the tweeter is crossed over somewhat low at 2khz, which can be a challenge for any tweeter to produce cleanly. I know titanium and likely aluminium domes were tested, but fabric domes offer better damping properties and might have played a role in its selection. They are rather larger and heavy, which certainly isn't cheap to build and are likely offering good value for the build. Experimentation with power amps may be best. I also have some concerns about QC as pair matching wasn't very good.
A question remains if the engineering was complete? We know that Elac has been looking to be a benchmark products at their price points, do they achieve that here?
Time will tell, and feel I would be interested if they proved to be exceptional at their price, but initial impressions are not indicating as such. I do look forward in hearing what will be said about them as owners have more experience.
