olds1959special Posted March 31 Share Posted March 31 (edited) How do you have your contour controls set? I use 2Ci's. I use +1 dB tweeter, -1 dB midrange I recently discovered this works better than simply boosting the tweeter.

GdnrBob Posted March 31 Share Posted March 31 It probably depends more on the room conditions than anything else, as well as the equipment used. Bob 2 Link to comment Share on other sites More sharing options...
olds1959special Posted March 31 Author Share Posted March 31 https://www.stereophile.com/content/vandersteen-2c-loudspeaker-measurements "I found a touch of lift in the high treble (tweeter set to +1dB) to be necessary to counteract the speaker's slight lack of off-axis air; this has to be balanced, however, against exaggerating the excess of HF energy above 10kHz. Though this might then be thought to leave the midrange a little depressed, I nevertheless found -1dB on the midrange control to give the optimal balance between the need for sufficient high-midrange energy and not to unduly emphasize the speaker's uneven response in the same region. This will be different for every listening environment and system, however. " Link to comment Share on other sites More sharing options...

The only problem is this is not where the Vandersteen alignment wants the listeners ears! John himself has written several times that his measurements are not like the measurement I send him (when reviewing our upper end products which have actual measurements included with the speaker) but they would match if he measured them where his ears are after I set them up. None of our speakers are designed to be listened to on tweeter axis. RV 3 Link to comment Share on other sites More sharing options...
ctsooner Posted April 1 Share Posted April 1 Great stuff Richard. Thanks. I've just never been an EQ guy, other than in my cars. I had a really special set up in my first car (new Mazda 626 with upgraded 15" black rims). I was a newly minted Navy Ensign and stationed in San Dog (I drove the USS Kitty Hawk or Sh!tty K!tty for short). I went to a high end mobile audio store just a few doors down from Stereo Unlimited (Bruce's place). I had all Zapco amps and EQ. We cut for all separate speakers and a sub in the trunk, which was rare in 83. The system cost over 4k and the car was purchased a few months prior for 10,250 total. It was my Ensign mobile and we partied on the beach with it constantly. Some of these threads bring back memories. For the home system, I was given an EQ for my system before I went to college, but I took it out as I didn't like what it did to the music. I used one at times when I was a DJ, but even then, I just cranked it up for everyone to get their groove on. For home it was my CJ PV?, Roberson and or Harvey's Moscode amp modified and Polk 10 Monitors with the Polk speaker cables on stands. TT was a Sota I also got from Bruce. Wish I still had it. That's the first time I met Richard as he and Bruce were in the back room setting up the 2's. I was mesmorized by the sound. Back to the EQ talk. 🙂. 1 Link to comment Share on other sites More sharing options...
olds1959special Posted April 1 Author Share Posted April 1 Regarding the aforementioned contour control adjustment on my 2Ci's, I previously found a benefit from turning up the tweeter by 1dB or so. But I never thought to also decrease the midrange by the same amount. It seems to almost create something like a U-shape similar to the frequency response of some speakers and headphones, creating more of an emphasis on bass and highs with less midrange. I feel these speakers are bass heavy by nature, so adding the tweeter boost helps, with the accompanying midrange reduction for overall balance and clarity. That's just my experience though. I really like what this adjustment does for my 2Ci's. 1 Link to comment Share on other sites More sharing options...
Oregon Posted April 10 Share Posted April 10 Decades past, receivers/integrated amps, those crap sounding SS buzz boxes. I had one, a Pioneer SA-9500. That thing benefited from a Soundcraftsman EQ ( made in California ) or a Vector Research EQ, ( early China stuff ). Had an MXR 1/3-octave passive EQ in my Pro audio days. Said EQs provided both the ability to affect tone and introduce more SS AC line buzz into the stereo. These days, EQ is largely handled through equipment choice, tube rolling, or, environment.

olds1959special Posted April 13 Author Share Posted April 13 (edited) Right now I'm testing a different dac which is very unlike my previous one, (lean, bright vs warm and fuzzy) and I found setting the contour controls on the speakers to flat helped tame the sound. I am happier knowing the speakers response is not altered if that's possible. Edited April 13 by olds1959special Link to comment Share on other sites More sharing options...
olds1959special Posted April 17 Author Share Posted April 17 (edited) I couldn't live with the speakers flat for more than a few days, especially after going back to my old source component. Now I'm trying boosting my tweeter by 2db and dropping midrange by 0.5db. This is a fun way to listen. It's like pumping up the treble a notch from before where I had it at -1db midrange and +1db tweeter. The 0.5db drop in the midrange keeps the sound cleaner to my ears.

olds1959special Posted April 22 Author Share Posted April 22 (edited) I just had to report, that I am very pleased with the sound of my Vandersteen's when they are completely FLAT. With the right components, cables, etc. I feel like I am having a supreme audio experience listening to them. My room is not terrible from an acoustic standpoint, there are some live surfaces, and some furniture to absorb sound, and enough open space. I'm no longer using any tubes in the signal path. Playing now is Billie Holiday's "Recital" on Verve, and it sounds great. My EQ is relegated to boosting treble for TV watching only.

ctsooner Posted Tuesday at 02:03 PM Share Posted Tuesday at 02:03 PM Great to hear and not surprised. Richard’s pre will be the only EQ I can see working. It’s out of the signal path somehow. He always figures these things out. Bass, EQ etc. no one else. Others to try and he gets patents. Go figure and THANKS. Link to comment Share on other sites More sharing options...
