I think the Ciare PR614 sounds slightly better than the 18sound, and the pattern does not narrow so much in the VHF region, but it does not go quite as low. From memory the horn crossover is about 670Hz (and about 3300Hz on the VHF), but the 12" go up to 900Hz. This produces a bump around 800Hz which is EQ-ed on the input. I found this gave smoother vertical off axis responses.I have to say the sound absolutely beautiful and go hard for such a small light box.I'm sure the DE990 would work ... but I don't know how well.Here is the frequency response (ignore the response below 200Hz) and step response which is almost text book for what it is.It was measured on a much better system than mine using a B&K mic etc.https://audioxpress.com/article/testing-loudspeakers-which-measurements-matter-part-2
