A bit of background: I currently have a pair of waveguided 2-way speakers, dome tweeter and 8" magnesium cone woofers, crossed at ~600hz, box tuned to 32hz or so. In my current room, the bass response suffers, and the system feels strained at higher levels. The speakers aren't very efficient (optimistically 85db at 2.83v) and don't put out much mid-bass in this room. My power amp is class d, rated at 380w RMS per channel at 8 ohms. After putting up with it for a few years, I pulled one of my subwoofers out and hooked it up (old GR Research 12" w/PR design, 250w). By ear, the 2.1 system still has major cancellations at the main listening position at roughly 55hz and 110hz (also probably why my mains by themselves have sounded so thin and anemic in this room). I'm in the process of getting a replacement amp for my other subwoofer (even older Hsu Research 10" design, 250w) so I can get the 2.2 system running and am eager to see if the additional subwoofer will yield a smoother overall response. The system (speakers and PC/TV) is in the family room, approximately 19' x 14' with vaulted ceiling along the long axis running from 8.5' to perhaps 15'. The 14' left wall is all glass. This space is open to a living room with approximately the same size and mirrored vaulted ceiling, a hallway, and 2 other rooms. It's hard to describe. I drew a rough diagram, but the forum software thinks it's spam. I listen to a very wide variety of music but most critically to jazz and classical. The system is also used for movies, etc. I would listen to more rock but it's never sounded good from any of the systems I've ever owned - always rough, harsh, and thin. For better or worse, my hifi systems have always called attention to how clean they sound, and when things aren't clean, they let me know. From speakers to the critical listening position is about 5 feet, but I can push the speakers towards the walls by a foot to get more space for driver integration if needed, and still have the rear of the speakers be a foot off the back wall. I also do a lot of listening throughout the rest of the home (trust me, the sound carries), and especially in the other large room where there's a table I can get chores done rather than lounge on a couch. I like it when the reverberent field in the other spaces sound like a live performance is in the next room over or down the hall. I don't listen at high levels often, but I think I would more often if the system sounded great at high levels. I don't watch movies at reference levels or higher because I have a toddler and mom will give me the evil eye (baby will be all smiles.) I'm thinking about trying out a pair of high efficiency speakers to try and get some more of the life-like dynamics of real instruments into the main room. I'm fairly familiar with live sound - play a couple instruments, have played in wind ensembles, marching bands, orchestras, and church worship groups (electric guitar/drum driven and choral) all my life. At the same time, I want something that is fun and just lets me enjoy the music. I don't need small pinpoint imaging in these speakers - real/live music is always large. Reading some klipsch heritage speaker reviews got my gear lust going again after years of being content. What I would really like to try is a really high efficiency 15" design, say the Vortex 15", but I just don't think the 6 ft^3 cabinets will work in this space. Maybe when the flatpacks are finally available and dimensions finalized, I can re-evaluate the 15" Vortex, but with things as they currently stand, I don't think I can in good conscience put two mini fridges in the family room (if I can't store cold drinks inside.) That brings me to the 12" designs - HT12, HTM12, and Vortex 12. TLDR: Can anyone lay out the pros and cons of the 12" designs, and any insights into how they might integrate into my system? How do I choose? Here's what I can gather so far: HT12 Pros: by far the least expensive and most efficient (97db), voiced with a bit more midbass punch than HTM12 HT12 Cons: cheaper drivers, less refined xover, less bass output HTM12 Pros: "higher quality" drivers, smoother response than HT12 HTM12 Cons: more expensive, "only" 95db with the new drivers, more "dry" than Vortex Vortex12 Pros: doesn't need speaker stands, deepest bass extension of the three 12" models, best for near/mid field listening at my MLP Vortex12 Cons: no ETA on flat packs, likely to be the most expensive, gives immediate buyer's remorse and makes you want the 15" instead, top octave falls off very quickly off-axis, likely higher distortion at higher levels than the HT/HTM series. Final note - my wood working skills are limited to what the fine folks at Home Depot will cut for me. I am willing to buy clamps and glue, but I have nowhere to store a table saw. I appreciate any tips. Thanks, guys.
