  1. You said that it was specific to Server 2003, not enterprise. And nope, it's the final version. Look at the build number. I'd like to see you beat this uptime

    21:50:45 up 122 days, 23:41, 1 user, load average: 0.00, 0.00, 0.00

    well i'd like to put a wallpaper on it, but in Server 2003 that requires a theme crack, and also requires a reboot

    no rebooting on that machine, i wanna get a really nice uptime on it

    What are you talking about buddy, you don't need any "theme crack"

    see???

  3. Well, I can't give you a full explanation of 'how decibels work' since I don't understand it all too well myself, but I'll answer you because I don't think anyone else is gonna reply to you anytime soon. I'm pretty sure when they say down 3dB at 30hz they mean that the sound coming from the speaker at 30hz is 3 decibels lower than everything else.

    As for the sensitivity ratings, those tell you how many decibels a speaker will put out on 1 watt of electrical power measured from 1 meter away. A Klipschorn, for example, has a sensitivity rating of 104 dB/1W/1M. While a Klipsch Forte has a rating of 98/dB/1W/1M. If I remember correctly, a 10 dB increase in sound output will sound twice as loud. Klipsch has a sensitivity chart that tells you about how many watts are needed to drive speakers of varying sensitivity ratings. Now remember, I am not too familiar with this subject and I wouldn't be surprised if I've made a few errors. I'll let someone else do the overview since they will be much more knowledgable (and accurate).

    I think BDC is hearing something which I do also.

    My Forte II and Quartets seems to have a very sparkely high end. This is in contrast to my home built units using the T-35 which is like the Klipsch K-77 unit. Unfortunately I don't have them side by side to confirm.

    The Stereo Review, analysis of the Forte reported exceptional good high end.

    My guess is that the Forte tweeter is indeed superior. It looks to be be more horn based rather than relying upon diffraction effects.

    My tests of the T-35 with a calibrated mic on the LMS system tracks Art's results. Above 10 kHz, it is rolling off. Therefore perhaps Art's data is not inaccurate because of uncertain qualities of the measurment system.

    I'm a bit undecided on what combination of qualities of the tweeter makes for good subjective performance. It is easy to mentally correlate lack of response at 15 kHz (measured how) with lack of zing. But most of us can't hear 15 kHz, or even 10 kHz.

    Rather, the issue is in the octave from 6000 Hz (or lower) to 12000. This is the area in which we can hear things. It is similar to the often observed fact that if you want impressive bass, crank up 120 Hz rather than 60 Hz.

    It is my thought that the Forte tweeter is much better than the K-77 and there is no way that easy tweeks are going to improve it.

    Are you saying that the Khorns are supposed to sound this way? My Khorns are the only ones I've ever heard so I don't really have anything to compare them to besides the Fortes. Between the two speakers, there is a dramatic difference in the sound. With the Khorns, I can turn the treble knob almost all the way up and it doesn't quite have those 'sparkly' highs of the Fortes. If this is the case (that the Khorn's highs are weak), then what do you suggest should be done to improve them?

    DeanG: As per your suggestion, I've emailed Bob Crites asking about his opinion on the diaphragms.

  5. I've retightened all the screw connections on the crossover (that is what I meant by 'free crossover tweak') but it did not seem to change anything. I ran a 20hz-16000khz frequency sweep and it sounds just fine, but for some reason it sounds a bit limited in the top end when playing music. I don't know what the condition of the capacitors are on the crossovers simply because I don't know what I'm looking at.

  6. I have a pair of '74 Klipschorns with type AA crossovers (with zener diodes) and AlNiCo drivers and they sound absolutely fantastic. However, there doesn't seem to be much high frequency sound coming from them. The tweeters are working (confirmed by ear), but you really can't hear the highs. I've powered these with an HK430 and a Dynaco tube amp. I've used a pair of Fortes in the same room with the same equipment and there's definitely a lot more top end on them. I've tried that 'free crossover tweak' from the earlier thread too, without much difference.
