since this is the section of the board i've gone to the most,i'm saying hello to y'all. i've enjoyed klipsch speaker performance for years,and sold/installed quite a few, and am now the PROUD owner of a pair of klf-30's and c-7 center (my 'children' as i affectionately refer to them). i'm driving them w/ a 60 lb. sony strda 777es dd/dts receiver. WOW! any tips on "break in" or easy mods, especially on the bass side, would be appreciated. i've played them about 5 hrs. also any questions about hdtv,a/v etc. please ask. thanks, av man

For improving the bass try this... To do this you will need an SPL meter (Radio Shack about $35 for a hand held model). Put the meter on the back of your seat of your listening position. Turn the unit on but DON'T MOVE IT! Next you will need some sort of pink/white noise generator (some separate eq's have them). Turn on the NG to about the same volume that you would listen to your music at. Again, don't touch these settings throughout the test! Draw up a grid-like sheet that lists "side wall" on a Y axis and "back wall" on X axis. The graduations should be about every inch for each axis (I started at 2" by 2") Next, move your speakers to about the closest to they can get to both walls, take a reading and write this down as your x" by y" measurement. Next move the speakers to the measuring position. Example: first reading was at 2" by 2" then the next reading would be from 2" by 3". It comes down to taking a measurement at about 160 some odd positions (took me 4 hours). When it's done just pick out the highest reading at a reasonable distance away. Keep in mind that when you start taking readings closer to the microphone it may be from just that: being closer to the mic. In that case you'll be reading an increase in attenuation and not room resonance, so you can use your own judgement to disregard those readings. In the end a couple of position readings will jump out at you. That's where the speakers should go.

After I did my room I put it all into an Excel file and drew up a graph for fun. If you want I'll e-mail it to ya.

Good luck!

P.S. To endure the noise for that long a time I put on some ear protection used in an equally expensive handgun shooting hobby. I also turn down the treble from neutral to -6db so as not to even give the tweeters a chance to overheat since they are the weakest driver in the cabs.
