Because it is only 10" vertical height and yields a respectable +/- 15 or larger (-6 dB) forward vertical lobe when crossed between 1.0 and 1.5 kHz.
Hello Zilch

Isn't that the same as the Nathan used in the Princeton measurements??

Yes, basically, but the conventional polar plot does not reveal intrusion of the vertical nulls. Look at the directivity map to see that.

Nathan's C/C distance is somewhat wider than is achievable even with the QSC 152i. Frankly, I was surprised to see how low Nathan is crossed to produce a reasonable-height vertical lobe. Earl concedes the Nathan waveguide is too small....

I still would like to see more comparisons using the Abbey instead. I think its very unfair to the discussion to use the nathan.

Exactly.

In a broad sense they are direct competitors, but how many DIY'ers are willing to spend 2-4 k on a kit? Alternatively, how many are willing to spend the time necessary to select and then build an econowave version if they could otherwise afford a to spend 2-4k on a kit?

Similar designs, yet very different "markets" (for commercial gain or not).

The direct competition i see is the OS waveguide which is not available vs all types of horns that are avaialble. Nothing else really is all that important to the discussion.

If an 12" OS Waveguide sold for $15 somewhere Im pretty sure there would be a Econo version of it. Considering Zilch has done amazing work already with so many other waveguide choices.

I also think there isnt enough difference for the $4K kit price tag, I remember a waveguide/XO/driver option way back being close to $1K for a pair though, times have changed This is DIY we build products that match comercial choices at the fraction of the MSRP of those product just because our time is free and our finish costs are seldom included....we like to ignore the real costs of our builds In the end though my "hidden" costs for my first set of DIY waveguides was around $10K if I was to charge back my time based on my consulting rate in business.

No problem but I have not seen a 12" elliptical OS option anywhere.
