Now THAT is a speaker!
I'm sure it would make a 1099 sound small and weak by comparison. (Is this thing even... on?
They should make a 1599 too, for those who don't need something so big and expensive as dual 18's.
Not sure if having the 18's 3.2ft apart like that is such a hot idea, but it might be ok with the XO at 100hz I guess.
A 1599 would be slightly better in that regard, but ultimately have slightly less SPL too, so...
Driver spacing was a huge
design consideration when I built my fronts. I was able to get my bass woofers within 1.2ft of each other, while also not having dissymmetry, by not going with 18's or 4-way; just 15's 3-way.
[Without going transparent screen and loosing 2ft of room depth, there is no WAY to fit 18" mids and tweeters in my room; and the UM-18 wasn't available then... so an all-18's design was a no-go.]
You'd really have to be a treble-head to need more treble than a Sentinel-15 could output.
A Sentinel-15 will output about [email protected]
Mine would still beat the 1899 below 40hz, but between 40 to 1.2khz the 1899 would win by about 4db me thinks.
I guess it depends on how much mid-bass and mid-SPL and scare-factor you are looking for in that band.
I have kicbin subwoofers that go up to 300hz with the same efficiency as the 1899 does (about 111db/watt for a set), so the 1899 would be all the more important to have if you didn't have kickbin subwoofers.
