Klipsch, DEf Tech and JBL are high on my list.
I'm not sure what JTR's sound like. The front Klipsch RF 64 has a fuller warmer midrange than my JBL "L-300" front speakers and thus with dialogue they are not as good to my ears as the front JBL monitors. I was really disappointed by this. I was hoping the RC 64 would take over, not degrade, dialogue. It seems to depend a lot on the source so I am not yet convinced they cannot be adjusted to push up the treble in the dialogue range and lower the "honky muffled tone in some but not all dialogue. I find myself switching my yamaha to "2 channel stereo" and not surround, to help clarity of dialogue in these cases. Again it is only necessary for some TV dialogue that sounds muffled like they are speaking thru a thick blanket. I picked the Klipsch because at least they used horn loaded HF and thought they might match the big JBL horns in sound character. They do not! My JBL 15 inch drivers cross over to the mid-range horns at 800 cps. The Klipsch a few hundred cps higher so I thought they might match the JBL character. They do not. The 15 inch guys are good down to the low 30's and even into the mid 20 cps realm. They seem to blend with the horns at 800 cps providing great punch. The Klipsch cut off sooner at 60 cps but are a sealed box so they do have great bass extension. The JBL are ported with a faster cutoff down in the 25 cps area.
The two RS 62's are far from "dipoles" and I suppose are classed as bipoles. As best I can hear, the two rear facing drivers on each channel are in phase
with the front facing drivers. Dipoles are 180 degrees out of phase
to keep from creating a single point sounding source. The RS 62's just point in two directions at about a 90 degree angle . They sound more like decent, powerful bookshelf units reasonable in bass content and power. If you are looking for added volume spread in a big room, the Klipsch RS 62s may fit the bill. Your speakers seem to match a love for powerful sound. Would you be happier with electrostatics in the front? If not, as I suspect, maybe the klipsch will work for you. With the YAPO Yamaha setup they are, for me, way too loud and act not like speakers that increase the surround sound stage but provide separate speakers to the sides to really fill up the room. Instead of sounding like rear sound bleeding into the film stage, they sound like separate microphones were used in the rear to gather detail on what was going on there,independent of the front and thus have equal importance. My old ones sounded better "surround effect wise". They were just cheap JBL 3 inch with tweeter surround speakers and I angled them up to the ceiling to get an spread effect, not a point second source. I sure do not see $2300 in improvement over what I had. Now this was just using TV stuff, not any movies yet. Possibly with movies they surround will be less made up than it is with TV shows. Maybe my 13x27' room is too small for this setup and just does not need these. The JBL front speakers and sub give me more volume than anyone could possibly want in the room. These seem to give a second source of sound not an extension of the front sound-stage adding some side and rear effects. If you are after dipoles with 180 degree phase front to back, the DEF techs are not described to be dipoles either. Maybe a pr
of some lower cost speakers wired out of phase on each side of the room and pointed at the ceiling could give you such a non localized effect? For $600 each, the Klipsch RS 62's do not do that. In addition, I struggled to hold them up and mount them at my age without help. If I get in the mood, maybe I will try to open them and put in a switch to change phase of the second pr
of drivers in the enclosure but that might not work as they are in the same box I would guess, not divided. Try calling Crutchfield and asking about some of their polk surrounds. They seem to have several surround units and carry a lot of speaker types so maybe they could provide some insight. Some surrounds can be wired either way and may fit your needs. I do not know what your speaker sound character is but maybe they could give some insight. Go to a local place that has some Polks to see what they sound like. I only went to the Klipsch 62's for the bass extension. Not sure it is needed though. To me $600 each was a lot for each speaker of a pr
of surround speakers.
My JBL's are about 8 dB less efficient than I see for the JTR T12 specs but can handle a ton of power. I hit the 18 incher once with a slap of over a kilowatt (250 watt per channel Heathkit amp with 3 db headroom, then bridged). It lit the overload lights and I assume that meant in excess of 1000 watts. and really shook some cobwebs loose. The horns can take 30 watts and output 112dB with 1 watt input.
I am eying up some room acoustic traps and am considering adding some "RealTraps" Mondos to get better control of low frequency room effects etc. I have yet to hear a speaker that gives better clearer dialogue than my JBL 300 mockups (all JBL components except their cabinets). Even my 4343 JBL monitor mockups are not as crisp as these L-300's for dialogue and vocals. Are you looking for vocal clarity or for increased fullness? I liked what I heard once, clarity and sound-stage wise on a pr
of Apogee speakers on a fortune in electronics but other than those and some B&W monitors, I am sticking to my JBL's for what I like to hear. JBL generally has a strong upper midrange which works well with vocals. Sounds like they are made for movies if you care about dialogue. If I record my daughter (light lyric soprano in opera work) in my living room and play it back on the JBL's, it sounds like she is standing there. The JBL front and side surround units just did not fit my placement issues and the front center unit was way too tall. I was considering putting it over my pull down screen it was going to be a major challenge. The Klipsch was also too much a challenge so I had to stick it on a stand shelf and increase the legs by about 8 inches to bring the center up to a reasonable height. If I had room for a bass driver in the center, I would have gone with a JBL horn compression driver and a bass driver. Have you heard any bipole versus dipole systems?
