One review of the Ulysses (in Dagogo) said they are not "full-range" and are somewhat lacking in terms of low end extension. Is that at all true?They are not "full-range" in the sense that they don't go down to 20 Hz or less. As I indicated earlier, though, their 28 Hz specification seems about right in my experience, based both on listening and on measurements I've done using test tones and an SPL meter. My strong impression is that most (but not quite all) owners of the Ulysses use them without a subwoofer.
As you've probably already seen, though, the smaller Daedalus models don't go down quite as far, with the Athena specified to 34 Hz, and the DA-RMa specified to 36 Hz.
Keep in mind, also, that all of Lou's frequency response numbers are +/-2 db. If he had based them on a looser tolerance, as a lot of manufacturers do, the 28, 34, and 36 Hz numbers would all have been at least a little bit lower.
