Well I could swing 2 LMS drivers but not 3, at least not at this time, mainly because I'm also thinking of amplification. I could go cheaper on amps but would rather buy nicer and not have to upgrade later...SpeakerPower was one I was considering although Crown and QSC would be heavily considered. And can you imagine 3 LMS 5400s in an 1800 cu ft room even if it is open in the back? There would either be pain or loafing woofers or both.
And then I'd be on the merry go round...you know, the one where you realize the low frequencies are so powerful your mains can't keep up and need to be upgraded.
So what drivers would you recommend I look at in the 15-18" range that would fit in 3-4 cu ft that wouldn't give up much to the so called best 18" driver made? I'd especially be interested in any that give me the flexibility in building a down firing box, which the Rythmiks 15" would allow but I read on the Parts Express site that the LMS 5400 is not a good candidate for down firing applications.
So on a tangent (but related to mains upgrade comment above) at 3am in the morning, and one I'm not sure I want to share since the speakers were so cheap...but since we're all friends here.
As part of the kitchen remodel, I wanted to get some really nice ceiling speakers. I actually bought some Definitive UIW RCS II (http://definitivetechnology.com/products/uiw-rcs-ii
) but had to sell them since I was going to put them up so they were aiming towards where most guests would be on the other side of the kitchen island where there would be a bunch of seats along the edge of the island. They sounded decent but I wasn't enamored with them but the real problem was the louder bass/noise going directly down, which is where my wife would usually be in the kitchen; this was of course a no-go since she wouldn't be able to hear anyone at even moderate levels. I listened to some B&W, Speakercraft, etc at some local stores but wasn't able to listen to the good stuff. I wanted to listen to Triads, which are supposed to be high quality in-ceiling/wall speakers but couldn't make that happen. I bought some speakers off of eBay thinking I could resale them if I didn't like them, Emotiva UAC 8.2, NHT IW-3, NHT IC-4, and maybe one other set. When my dad found out, he gave me a set of in wall Focal Chorus IW 706 V that he never used. As an aside, I also tried several subs such as Sunfire HRS-10, Boston Acoustics Sub10F(passive, in-floor/ceiling) (only $150 shipped including cabinet), Atlantic Technology IWTS-28, before deciding on the Rythmik DS1200. After listening to all of the ceiling speakers, I decided the NHT IC-4 (http://www.nhthifi.com/iC4-ARC-In-Ceiling-Speaker?sc=12&category=1212
) were the best for the ceiling in the kitchen. The link is to the new model coming out soon but has similar construction although I am told by NHT that the new ones are a little bigger, faster, better or at least structurally more solid.
The cool thing about the IC-4 for distributed use especially is the 3-offset tweeter design that has 3 tweeters in one with each facing 120 degrees apart (go to the link if you're interested as the picture is better than I can describe it). Even better, since the NHT IC-4 had been discontinued, I was able to get pairs for around $300 and sometimes less. I ended up buying quite a few pairs after I decided I liked them so much that I was going to build boxes for them and replace my Focal Sib XL system for theater duty. I like the NHT IC-4 that much that it will now be my home theater fronts, center, and rears along with kitchen ceiling speakers. I plan to build some boxes that will go up near the ceilings (bulk of the box will actually extend into the ceiling joists to keep lowest in room profile and will be drywalled and trimmed to blend in seamlessly) and aim down toward the primary listening position. I hope they sound as good in home theater placement as they do in a box on the counter (listening on & off-axis) or it will have been a lot of wasted box-building effort.
Thanks again bass addict.
