De meting die ik toen heb gebruikt kan ik zo snel even niet meer vinden. Hieronder wat ik nu gevonden heb van wat ik bedoelde, de waarom het beter is te doen. Tweede gedeelte is hoe je het moet doen.
Ik heb zelf een SB1000, die van mij zit qua output nadat ik deze op nul heb gekregen ook ongeveer op 10%-15% vermogen….
Al met al kan iedereen vinden wat die vind. Punt blijft als jij vind dat bij jou thuis een andere manier beter klinkt, of beter voelt dan zou ik dat gewoon aanhouden…
Hopelijk engels geen probleem
Have fun..
If the you notice the level of the subwoofer is set to -10dB or a higher negative number in the receiver, it probably means that the level on the back of the subwoofer is set too high. If the level control on the back of the subwoofer is set too high, this can cause the AV Receiver to run out of level correction range when MultEQ tries to set the subwoofer to reference level. Lower the sub level on its back and run the auto calibration again.

A. Calibrate the subwoofer volume
1. Some products equipped with Audyssey MultEQ XT32 have automated the subwoofer volume calibration process, making steps 2 – 8 below unnecessary. If you own one of these models, proceed to section III.
2. Set the volume control on the subwoofer at the middle (i.e. 12 o’clock) of the adjustment range allowed.
a. Please note this “starting point” may not work with all subwoofers.
3. Place the microphone at the first measurement position (see guidance in section V.) and proceed with the calibration process for the first measurement—until all speakers have been measured once.
4. After the first measurement process is complete, select "Calculate", then go to "Check Parameters".
a. Audyssey will calculate the speaker distances and trim level settings from this first measurement.
b. Each manufacturer has a slightly different interface, so the terminology may not exactly match.
5. Check the subwoofer trim level setting in the receiver / processor menu.
a. If the subwoofers’ trim level is at the maximum limit of the cut (-) or boost (+) adjustment range allowed, you need to adjust the volume control on the subwoofer and repeat step #2. Specific instructions will follow.
b. Trim adjustments are a tool used to achieve the goal of producing the same Sound Pressure Level (SPL) from each speaker / subwoofer in the system.
c. For example, Denon receivers have a trim adjustment range from -12dB to +12dB.
6. If the subwoofer trim level is at the maximum boost (e.g. +12db), turn up the volume control on the subwoofer slightly and repeat step #2.
7. If the subwoofer trim level is at the maximum cut (e.g. -12db), turn down the volume control on the subwoofer slightly and repeat step #2.
8. A suggestion for tweakers is to adjust the sub volume such that the resulting subwoofer trim is in the range of ±3 dB.
a. This is only a suggestion for the tweaker who likes to play around.
b. Audyssey’s position is to perform steps 4 to 6 above.
• Note: This process is for checking the subwoofer trim levels only. After you have completed the subwoofer setup, be sure to start the measurement process over, following the guidance in section V to use the maximum number of microphone measurement positions available.
