mathu126, these speakers are aperiodic right? I believe in his writeup curt said they put a hole in the box and stuffed the box greatly in order to tighten up the bass. Since the driver appears designed for car audio, it doesn't hurt the bass much as long as you use a sub.
Kevin, you based those aesthetics on Revel Salon 1s didn't you?!
I think that on some music and in some movies, the treble is not high enough. Almost seems muffled.
Often when people first start to live with neutral speakers, they seem a bit "dead" or "uncaptivating" in the treble.
What you'll find is that what high frequencies are there will be reproduced, but the speaker isn't adding anything fake that your untrained ear may have "expected". Boom and Sizzle sell, but often sound nothing like real female voices or violins or triangles. it's not the speaker is necessarily muffling the treble, but rather the treble wasn't there in the original recording.
That said, we are talking about a $17 soft dome s tweeter here. Nothing wrong with that, but there's definitely
more resolution/detail to be had from a pricier tweeter, like the $95 fountek used in the aformentioned Statements, or the De250 used in SEOS-12s.
I definitely agree with raising the tweeter up to ear height
though - that's where it should be, as vertical lobing between the mids and tweeter will mask upper midrange / lower treble details compared to straight-on, and the tweeter's directivity will mask upper treble detail when sitting off-axis. Don't be afraid to toe the outer speakers in by about 15 degrees.
