    Speaker/Room calibration

    Hey Bruce, Good to see you are back at this again. I was hoping you were not giving up on it. I am really pleased by the FR you are getting below 100Hz. Can you post your MDAT for us that have REW so we can follow along. The new measurements how different is the position of the speakers...

    Move your listening chair and hold on for the ride!

    "An audiophile friend of mine who has been in this hobby for a long long time has scratch marks on the floor where his listening chair is. He always moves his chair depending on the recording material. He does this in order for him to enjoy the moment of each and every record material he has, be...

    How loud do you listen?

    Wendell, I set my volume control to one position when doing critical listening. The system is calibrated to 83 db. I let the recording determine the loudness. If the recording is done correct it is very listenable. If the album is screwed up that's what it is. No adjustment will fix it. A...

    Speaker/Room calibration

    Bruce, I see a lot of suggestions for speaker positions. Try them and post them here. I'm looking to see if we can fill in the part between 80 to 200. be sure to link to your MDAT. Also do the sweep to 1K. John

    Speaker/Room calibration

    Bruce, Thanks for posting the MDAT. I looks like the 70hz bass filter gives the flats results but lowers the area further up. Can you lower the x-over point on the mids. I looks like that rolls off at 200Hz. Is it possibe to move the speakers around. I'd like to see how that effects the FR. I...

    Speaker/Room calibration

    Hi Bruce, Can you do the bass filter 50 to 100 in small steps. I am looking to see what happen between 50 and 80 Hz. I want to see here that flattens out. Also can you show a full range. The 200hz looks higher then normal. Be sure to calibrate the REW SPL meter to the external SPL meter. If...

    Speaker/Room calibration

    NorthStar, At this point it is all about test tones, math and measurement. Without it there is no music. Why else would we be here. The test run by REW is very short only a few seconds long. I am sure most you have heard sweeps before, these are no different. Jacks point is as you run thru the...

    Speaker/Room calibration

    Bruce, This is great, atleast we now know what each control does. I have got to tell you this will not be a 1,2,3 i'm done thing. Like I said earlier, I have been doing this for years. We just need to find the correct combination of position vs controls. One question - what FR do you want...

    Speaker/Room calibration

    Hi Bruce, The position changes you formed really helped. I know we can do much better. Please post 3 graphs for us. One thing you have to do is make sure whenever you do this, keep the mic in the same spot ever time. I have it marked on my floor. Keeping the setting the same run the first...

    Speaker/Room calibration

    You guys are moving way to fast. Bruce posted 2 graphs, Hasn't shown what the contros are capable of dong and you have him getting 3 to 4 subs. Nothing like throwing gas on the fire. He needs to get a base line, figure out that he can achieve thru speaker and listening position, what the EQ...

    Speaker/Room calibration

    Bruce, One suggestion, When doing this just change one item at a time. By doing that it will make it much easier to see what each change is making. by changing 3 setting and posting a graph we can't see exactly what each control/ move is doing. Also when looking at the bass freq. show the...

    Speaker/Room calibration

    Bruce, I have been using REW for about 5 years. I used the RS digital meter and found it fairly accurate when compared to my calibrate mic. Don't think using it will throw off you measurements that much. This will be interesting to see how you fix the null/peaks in the bass using just the...

    Finally a Counterpoint Forum

    I only had problems with microphonic tubes with only certain tubes. I don't think it was a problem with the SA 7 just the tube. I never played with tubes that much. I did last year come across a lot of tubes and have been swapping them in and out. I like Telefunken (sp) in the phono and Semans...
