    Jubilee, Jubilee or Jubilee?

    Chris,

    I was wondering if anyone that you know of has the EQ settings that Roy gave to some forum members for the Jubs. I, like many folks here, spent a long time tuning and tweaking my set to get a balance that was consistently satisfying. I finally stumbled on an article about equal SPL contour lines across the frequency spectrum. I was previously unaware that our hearing was significantly different with respect to frequency (other than the normal rolling off of the extreme low and high fequencies) and subsequently found out that my hearing was significantly different in a few frequency bands than "normal" or the ISO standard. I discovered an online site that produced an equal hearing contour line based on an interactive test. I was amazed at what I found. So based on the results of that test I made some changes to my EQ settings and it made all the difference. My EQ curve looks very different in a couple of the bands than "typical." What I did was compare Roy's Freq\SPL data to that of the test results using 1KHtz as the reference point and calculate the difference. For example, if my hearing at 3KHtz is plus 8 (from the reference) and the speaker is minus 2 then I adjusted that band down 6dB to be flat to the reference. Not sure if this is something anyone else has tried of it it even makes any sense but the results I achieved were very favorable.

    However, this data from Roy was measured in an anechoic room and I was estimating the numerical SPL at each frequency from the chart, not a table of data. If I had his actual EQ adjustments I could see how that compares to the adjustments I have made based on the charts and my hearing test without the aide of a real time analyzer. It sounds very good to me but I am very curious as to how my adjustments compare to his or other forum members.

    Hey Roy,

    I don't know that I have ever thanked you for those wonderful speakers you and Chuck worked so hard to get me. So I would like to do that now...Thanks! I Talk to and email Chuck frequently ant still owe him pictures of the completed room and set up from our last discussion a few months ago when the KPT 884 showed up. I use a complement of 3 BGWs for the Jubliees and a QSC 4050HD for the sub. I remeber reading somewhere that PWK had an affinity for one particular amp that is near and dear to my heart, the BGW 100. It was back in the early 1980s that I started using those amps, and Klipsch speakers, in part because of each products reputation. That was a very important factor for me in selecting the amplifiers I used for the speakers you designed...PWK's opinion of the BGW 100. I am certain that there are some other amps (both Tube and SS) that would sound better on some recordings and not as good on others but I like what I have and it sounds good to me. For me I think it was the opinion PWK had of that amp and the nostalic experience of going back in time for me that was the two biggest determining factors of my slection...and I think it sounds very good none the less.

    I have played around with settings and balances, EQ...etc etc for a year and a half or so and found the "tune up" that sounds very good to me without contantly changing bass, treble or the balance between the amps between each song. And I admit that although I break out an "electronic measuring device" occaisionally the over riding factor is whats sounds good to my ears. And while I am sure there are purchases that I could make that would enable me to travel a little farther down that yellow brick road to audio nirvana, I have come to that place in the road where I am fully content. I think anything else would be just "different"...not necessary any better overall and most certainly not worth the added expense.

    Thanks again!

    hey eric,

    i am glad that you like the 3 way jubs. you were the first and only three way guy (that i know of) and now you have an 884 to boot (bill hendrix also recently bought an 884 for his jub ht; ask him about it)! most songs are not mixed flat (either bad engineers or bad monitors or both) and so you have to flavor the top and bottom end just a bit. i would like to see pictures of your setup if you don't mind.

    in Christ, because of God's grace,

    roy

    Will do Roy. I would like to hear your thoughts on the arrangement.

    Welcome back 6foot8

    I would love to see a picture of your room showing the three way jubs and the electronics.

    jc

    Thanks, I have been meaning to get pictures to send to Roy and Chuck. I'll try and borrow a digital camara from a friend. I don't have a decent camara and the disposable one take lousy pictures as can be seen from my posts.

    Question for Trey or Michael

    Hey JC...I chose the 884 because unless I am misinformed it digs lowest of all the cinema subs. I have only one (at the moment) and am using 2 DBX crossovers that I already had. I would love to switch to the EVs but will need to save a little before sprinning for a pair of those.

    BTW one of my best friends graduated from West Georgia College way back in the 80's before it became part of the state university system.

    Hey JC...thanks for the kind words. I'm not a big cyberspace forum fan, like face to face interaction better. I try and keep my opinions to myself as I have learned that it really dosen't matter what other's think as long as you are content with where you are at.

    I do have my 1133s XO'd at 400. I will float an observation out here that will no doubt attract some controversy but again it is just my opinion. I have tried to XO the mid\highs on my Jubs closer to the customary Heritage 4.5-5 kHz range in an attempt to minimize any distortions and unwanted irregularities in the voice range. This was really unsucessful though as the 1133s loaded in the 402s tend to become to beamy and harsh (again this is just my opinion guys) in the 3-3.5 kHz range and required way too my EQ to get a comfortable and natural sound. I am in no way making any criticisms here as I love my system and would never have anything else (unless I lost my hearing). I think (and I could be wrong here as I have no knowledge of Roy's design philosophy or intentions) the recomended XO point at 3 kHz using a 24 dB\Oct L-R algorithm almost eliminates this beaminess and uncomfortable sensations in that 3-3.5 kHz area. This is why I prefer the 3 way set up. It is my opinion that the 1133 loaded in the 402 horn sound better XO'd at 3 kHz than a 2-way set up using the same components where the 1133 runs out to 17kHz with no EQ in that 3.5 kHz area. Just an opinion folks but I have kept that to myself because it will surley raise a few eybrows anyway.

    I have completed an extensive redesign of my room with generous amounts of acoustical treatment courtesy of ATS acoustics (no foam here all custom mineral wool designer panels), placement of Jubs on the long wall and 2 years of experimenting. Everyone who listens to this setup without exception prefers the lower XO point with very little EQ to the higher XO point with much more EQ.

    The KPT 884 added a dimension to the quality and presentation of the sound that almost can not be explained with words...it must be heard and felt to appreciate.

    Oh well sorry for rambling and hope that my input does not step on any toes just how it sounds to me...

    No passives on my setup. I am really very satisfied with the sound as is. I cross the 1133 on the 402 just under 3k. That seems to control the "beaminess" I was sensing around 3-3.5k. I had tried a higher crossover points 5-6.8k but always needed to much equalization in the 3-3.5k region so I went back to the recommended crossover points. I think the HF driver sounded a little better a 5k then at 3k but the overall compromises are minimimized at 3k.
