Other then getting new front speakers this appears to be the only solution.

e)6. What do I do if my trim levels are at the limits of their adjustment ('maxed out')?
During the calibration, Audyssey sets each speaker's volume level so that all your speakers are playing at the same level, relative to each other, after the calibration is complete. These settings are called the 'trim levels' and you can see how Audyssey has set them by going into your AVR or Prepro's menus.
The range that Audyssey works within depends on the make of your unit: for Onkyo it is -12dB to +12dB for the satellites and -15dB to +12dB for the subwoofer; for Denon and Marantz the range is -12dB to +12dB for the satellites and the subwoofer. For other brands, check with your user manual. After calibration, all your speakers should show a trim setting within these ranges.
It is important that no trim level is 'hitting the stops' or maxed out. The reason for this is that if you do hit the stops, you have no way of knowing if Audyssey would have gone even further if it had been able to. So if, for example, your sub is set to -15dB, then there is the possibility that it could have been set to -17dB if Audyssey had allowed it.
If subwoofer trim is maxed out:
Ideally, your sub should be in the trim range of approximately -3.5dB to +3.5dB. If your sub is not in this range then you can adjust it by using the sub volume control knob and running Audyssey again until you get the trim where you want it.
Also, one of the reasons for having Audyssey's subwoofer trim level in the +/- 3.5dB range is that values closer to -12 dB might prevent a subwoofer's Auto-On feature from working because the output of the receiver would be too low. (We recommend that if your sub has an 'Auto-on' setting on its power control, to turn this OFF before running MultEQ. This will ensure the sub always 'wakes up' when it is first pinged.) There is another reason why it is important to aim for a sub trim in the approximate range of +/- 3.5dB and this concerns the safety of your sub and avoiding damage to it. Please read this FAQ Technical Note for more information.
If satellite speaker trims are maxed out (external amplification):
However, what do you do if your satellite speaker trims are maxed out? They do not (usually) have volume controls. The trim levels are determined by a combination of several factors - for example, the efficiency* of your speakers, your amplifier gain, room size, speaker location etc. It is unusual for one or more satellite speakers to be maxed out but it can happen. If you are using external (separate) power amplification with very efficient speakers, then a good solution is to use line level attenuators or 'pads' (see link below for examples). These devices fit between the prepro and the power amp and reduce (attenuate) the input signal to the power amp. They are passive devices so they have no negative impact on your sound quality at all but, as always, the advice is to choose good quality components.
If satellite speaker trims are maxed out (internal AVR amplification):
If you are using an AVR's internal amplification, follow this procedure: you can use an SPL meter to make sure that the levels of the speakers are the same. If they are not, then make adjustments to make them the same. Example: assume your centre channel reads 78.5dB, your surround left channel reads 77.5dB and your right channel reads 76.5dB, all with trims of -12dB. Adjust the trims so that all of your channels read 78.5dB (the loudest level of the set of measurements you just made). This will ensure that all of your channels are now set to the same level - in this example 78.5dB.
After that, turn down the master volume (not the trims) until the measured noise is 75 dB on the SPL meter (C-weighted, Slow). 75dB is the target calibration level in a system adjusted to play correctly at Reference level. Write down that master volume setting because it is now your new reference listening setting (instead of the 0 dB setting normally used). You will need an external test disc if you wish to complete this step because the master volume control is inoperative when using the internal AVR test tones (although users report that on some Denon units the MV is operational when using the internal test tones). Alternatively, it is probably reasonable to assume that your new Reference level setting (in this example) is -3.5dB and not 0dB - in other words, the same amount by which you raised all the trims above the level of 75dB. Be aware that since you have changed the Reference Level setting on the master volume, Dynamic EQ will not function exactly as intended as it assumes that Reference level is 0dB. You can compensate to some extent for this by using Reference Level Offset.
