the main reason for turning the speakers around will be to lower tuning.  It also shrinks the air mass-which better couples the drivers together.

if you have two, do the changes to one and listen to them one at a time to determine which allignment you like best.

each way you arrange the drivers and wireing will sound slightly different. you have to try different arrangements and see which one you like best.if you like what its doing now, leave it for a few weeks and change something later, when you have a couple hours to kill and you feel like it.

Thanks for the help JRock and 60ndown. I have switch one of the HWK15 around and plan on running my test today. I will be using AVIA (LFE 100Hz sweep) and my SPL meter to check the difference in DB. I plan on taking readings directly from the ports top and bottom. Do you think this will be an accurate test? I will be testing different movies to see how each HWK15 sounds and SPL output. I know both of you are right. Listen to both set ups and figure out which one sounds the best. Trial and error is the only way to learn. THANKS

WOW! Dirtdawg that info really helps. I was unsure if direct port measurements was the way to go. I sometimes get hung up on SPL. I know it is not the most important but old habits die hard. When testing movies I try to take SPL measurements from the sweet spot/main viewing area. I have been looking at an audio analyzer from MCM ( part# 555-7440). I was curious if anyone had any experience with audio analyzers and would this device help me get away from the SPL meter thus tuning the system to the room instead of to my ego. THANKS.

A real time audio analyzer is nothing more than a SPL meter with a certain standard set of frequencies tuned in to show a graphic display of the overall spectrum simultaneously. The 2 units each have specific advantages over the other and are designed to serve 2 different purposes.

The analyzer is mainly used to set an equalizer in a sound system for a desired and repeatable response curve, whether it's flat or tailored to individual preferences. It will take some of the guess work out of setting a system to a predictable tolerance. While a SPL meter can be much more sensitive to room resonances because there is no certain group of frequencies it is tuned to, it can also be very distracting when trying to set an EQ.

The best use of an SPL meter is measuring frequency sweeps for finding problem frequencies and room nodes and dealing with them. Since there are no set frequencies tuned in that the SPL meter works at, you can find very narrow bandwidth response problems that a spectrum analyzer will miss. Some meters have interchangeable microphone heads that alter the pattern of directionality, making them even more useful. But, it's also fun to brag about max SPL!

Most of the Pro Audio type analyzers are set to display 1/3 octave centers all along the audio spectrum, but many are less sensitive and not very effective. If you already have a meter and aren't planning to set the system up a different way or in a different place every few days, just use what you've got and spend that extra money on disks.

Also, remember that in order to get the most accurate results using either type of unit you should place the microphone on a stand, because the proximity of your body will affect the readings.

I hope that helps.

The best way to use the same unit for both music and movies is to have a separate amplifier for the LFE/sub channel. I find that modern (DTS encoded) movies are recorded with far more Low Frequency and Hi Frequency content than music CDs. I end up changing the sub amp each time I switch from movies to CDs and back. It would be great to use a remote control sub amp for this, but I also cut the HF control some for CDs. I'm a little picky with music and I watch a lot of older movies so my problems and solutions may not apply to your situation.
