Help with understanding Stereophile test results.


Hey all,
I ran the Sterophile test tones and just wanted to know if anyone can explain any potential issues based on my numbers, they are as follows:
R L
1K 80 81
200H 68 80
160H 67 78
125H 74 79
100H 74 79
80H 70 74
63H 68 70
50H 67 70
40H 76 73
31.5H 75 76
25H 72 75
20H 65 67
Thanks for any help or insight you can give, Cheers

I never thought anything was really bad or lacking so I just ran the test to see what it says, after talking to a dealer friend it would appear I am not that bad off but I suppose I need to check these against a compensation value for the digital Ratshak meter I used. Any reason for the weak midbass?, and if so what should the values be..in the low to mid 70's? Thanks for any additional help.
This is a speculation, but I am wondering if the midrange drivers on your speakers are starting to roll off in the mid bass, which is where many speakers roll off...then the woofers kick in. It could be a less than perfect crossover integration between the mid and bass drivers.
Those aren't bad numbers. The broad bass dip is not all that substantial and better than any sharp peaks. Room treatment is difficult to nearly impossible in that range but it wouldn't hurt ... too much.

If that 10 dB is really that noticeable, perhaps the best cure would be a Rives PARC or one of the digital equalizers.

Well chosen but modest system. Flat would be optomistic and unrealistic.
1. Those are not bad numbers.
2. You need to measure more, both in terms of frequency spacing and multiple readings. In-room frequency variations are generally sharper than can be distinguished with certainty from one measurement at only one place.
3. Room treatment down to 100-125Hz is readily doable. Below that, it becomes fairly bulky and inconvenient but still doable.
thanks guys for all thoughts, I never heard anything bad but I ran the test to learn more so just trying to make sense of it all....................much appreciated.
