lol no i dont need speakers that play that loud but it would be nice for movie trasitions and peaks . the hole reason really would to be keep them a idle low distortion at high spl . i listen to music about 90 rms and 95-96 peaks 100 spl if i have a bug but thats only one song and not often. IMS bought a pallet of them thats part of the reason i got them cheap . they do have a return policy. eddie sulivan was my contact there maybe tell him that steve that bought the lsr6332 told you about them he might give a better deal . other wise ebay i got ok deals by contacting the selllers with the get a quote option and the best price was 1129 shipped .
so has anyone noticed a bit of peaking i dont know what i would call it with the lsr6332? best way to describe it is think female vocal LOW vocal seams to beam i think its the woofer beaming not sure . not a big believer in speaker break in but the front L-R dont do it as bad a s the center . center is newer and placed as good as can be . i have a usb card comming so i can run room eq to see if it shows up or not . other than the beaming ??? they are a absolutly great speaker . side note anyone heard the EVENT OPEL ? |

Regarding the beaming, at approximately what frequency is this occurring at? The 6332 have really nice on and off axis frequency response graphs in their literature and hence I would suspect its a room/eq issue.
Re the Opals, I've read at least one review stating that their noise floor is rather high, high enough to be distracting in normal use. I haven't heard them though. |

i figured this much as why would jbl use them in there own reference room if they beam lol..... i will be able to run a room sweep in a few weeks .
what freq? not sure think female low octave ? what ever freq it is it does not have to be a vocal but a female vocal like mariah or christina when they go from high to a very low vocal it is noticable. these speakers really do sound fantastic it would be very hard to make a big step up from them . the tweeter still amazes me. the opel just peaked my interest because of the aluminum case, wave guide tweeter, 36mm xmax on the bass driver and a very interesting controll on the bass driver and they seem very proude of it . its nice to see companies trying and giving a good price . so the amps are noisy . its always the little things that get forgot. |

my room is treated and i took some back panels and put them behind above below all the way around made no diff . so it pushed me to finaly get off the couch and buy a external phantom powered sound card to run room eq . i am not a believer in speaker break in but they really seem to be getting better its not just me i am very sharp to things and it bothers me
my integra has audesy room eq and it does nothing for it . thats ok i hate the audesy kills the sound heck i cant even spell it . its not horable i just pick up on it . i have a sms1 bass eq and no kidding at the listening position i am flat from 14HZ to 200 i sit about 12 ft from the speaker face to my ear that should be plenty of air space for the speaker to fan out (i hope) mid feild ? right .these are great speakers and i dont think they are the cause it is very minor. i just figured this would be a good place to ask as there are people who actually own them on this forum but i need to learn more about room problems and i finaly bought a tool to do it and i can help others now like my dad and brother inlaws . but now i cant say i cant help guess i will have to play sick. i did fix my screen that was resonating coherantly that was just weird .

pdandy -- I have reservations on your use of two 6328's for the center channel. Respectable speaker manufacturers will always have tweeter and midrange in a vertical placement configuration, even on a center channel. The reason is that our binaural hearing is on a horizontal plane. Depending on the distance between tweeter and midrange (it should be as short as possible), one will have "lobing" especially at overlapping frequencies of the two drivers. When using two horizontally placed monitors with phase locked output, you fall head first into an abyss that should be avoided based on good center channel design topology. First, you introduce drivers with horizontal placement. Worse, the distance between these drivers is anything but short. And even worse, the frequency range affected isn't the small overlapping range of mids and highs, but the entire spectrum! This would very seriously compromise room sound.
If you have extra pair 6328's, try this to expand the width and depth of soundstage. Place the speakers at 60 degrees from center on each side. Feed them the same signal as your main left and right speaker (at 30 degrees presumably) respectively. However, dial down amplitude a couple of decibels to maintain imaging specificity. They must not be phase locked to main left and right - introduce a delay of between 10 to 20 milliseconds. Enjoy. |

Tumara Baap.......I appreciate your input, although I believe your reservations are unfounded in my situation. The two JBL LSR6328P's are placed vertical, as their high frequency wave guides are not designed for the speakers to be placed horizontally. Between the two 6328's is the JBL LSR6312SP powered subwoofer, which is placed horizontally with the 6328's placed at each end of the subwoofer. My center channel output is stable and has full frequency output. There are no serious peaks or nulls across the frequency spectrum, and the center channel speakers do not demonstrate time alignment problems with relationship to the sweet spot. Actually, I have a wider sweet spot across the couch where we sit to watch movies, so it is better for all. In the sweet spot, the distance between the tweeters and my ears are exactly the same distance from each speaker, as is the distance from the low/mid frequency drivers. I detect no lobing issues, phase alignment issues, time alignment issues, large scale frequency dips in the upper midrange, or anything else engineers attribute to lobing effect, at least none that I am aware of at the listening positions. The whole surround sound system sounds wonderful, including the center channel. Lobing is a complicated subject. It requires accurate frequency spectrum analysis plotting to reveal if this phenomenon exists between tweeters and midrange speakers. It is well known that physical placement of the tweeter(s) in relationship to the midrange driver impacts the frequency range output of those drivers when combined. D'Appolito's research, and his famous design have gone a long way in addressing the issues of speaker lobing. It is an interesting subject to consider and discuss. Your point was well taken. By the way, welcome to Audio Aficionado.

jdandy, I gathered from the pic posted that -each- JBL 6328 is indeed vertically upright. Hence the drivers are one on top of each other insofar as each monitor is concerned, but not in relation to the second 6328 on the other side of the subwoofer. And it this horizontal spacing, up to a couple of feet apart, that might generate lobing. I have heard of situations where two speakers have been used for center channel, but instead of being placed a few feet apart on the horizontal plane, one was placed below the viewing screen, and the other immediately above the viewing screen. Hence ALL transducers between the two speakers were on a single vertical plane. I would suspect this latter set-up would be more amenable to a smooth dispersion.
In the end of course, your own ears are the final arbiter :-) |

Tumara Baap.......I apologize about describing the speaker orientations to you. I had not revisited this post in awhile, so I forgot I posted all those photos of my studio and control room.
The idea of one center channel speaker over the widescreen, and one under it vertically aligned is an interesting concept. I had never considered that idea. For now, though, I am sticking with the present plan. If it ain't broke, don't fix it.
