correct settings/ANEMIC performance

I just had an audio consultant set up my vtf-15 and martin logan speakers .he used audessey,then a test tone sweep,with an spl meter.Then he tweaked the distances with his ears. the system sounds very accurate ,musical ,and nice to listen too.settings-eq-1,one port,phase 0,vol-9 oclock,q-5.5.
However,video's are lacking the dynamic punch that I am use too .there is a lack of sub woofer feeling.my consultant recommended a jl-113.
any suggestions would be appreciated.my loyalty is with HSU!

He tweaked the distances with his ears!? That sounds strange. Why wouldn't he have let Audyssey do that? Anyway, if he was doing his job then he set the sub to play evenly with the speakers and with as flat as an FR as possible. You might be used to hotter bass which is why your system might sound dull at the moment. I would turn the subwoofer channel up in the AVR when its movie time to get the sound you want. His recommend of a JL Audio F113 is ridiculous. If all he did is run Audyssey and check its response, I really hope you didn't pay him a lot of money. That is something you can do yourself along with a $30 SPL meter just as easily.

As strange as it sounds, I actually adjust my distances by ear after running Audyssey. Audyssey gets the distances pretty close, but I still get a big sound quality improvement by doing my by-ear post-calibration tweaks. The key thing is that I have special pink noise samples that I use that play correlated noise in adjacent channels. I then adjust the distances until each adjacent pair of speakers (plus the front left and right as a pair) images the noise convincingly dead center between them. When I do this, I change the units used in my distance menu from "ft" to "m" because I get about 3 times the granularity (0.01 m vs 0.1 ft) with units in meters.

The pink noise samples aren't suitable for setting sub distance, and I don't think one can get the best results setting the sub distance by ear. Not only that, but sub distance makes a big difference for good bass. On the other hand, this setting doesn't need to be as precise as for the speakers. Differences of 0.5 feet don't change much. Something you can try doing is temporarily adding or subtracting about 7 feet (assuming you crossover at 80 Hz) to the current setting to see if that improves things. If it does, then it probably wasn't set right to begin with. The best way to set this right involves taking measurements with an SPL meter and test tones or, preferably, a room measurement system.

Another possible reason for poor bass is placement related. Can you post a picture of your room including adjoining areas, where you sit, and where the sub is?

I adjusted the sub output from -8 to -4 on the avr.i popped in enders game and the whole house came alive.the vtf-15 rocked the house.thanks so much for the advice.
my question of the day - would a sub-such as the jl-113 not have to be adjusted 4 db for video versus an audio use?
have a great day!
