Funny you mention Paradigm, my sub is a PDR 8. I also have all my speakers set to small. I only adjust the sub level on my sub. My receiver doesn't have cross over cut off so assume its 80. Sub is set to 80.

Your right about crossover cut offs. I did some experimenting a while back by turning off the sub and doing a sweep all channels (speakers only) and found that even though my speakers alone lack bass the sweep went well below 80hz and it wasn't a cutoff it was a gradual fade out.

Hmmmm good to know. I wonder if all receivers/amps handle the cutoff the same way. I tend to stick with Yamaha for receivers so I'll try this when I get my new one in a couple of weeks.
BTW Ironbull I'll be shopping for a new sub in a few months. Still deciding between a Paradigm or Velodyne sub. They're both really good. I read good reviews about your 8" Paradigm.

Most receivers handle crossovers slightly differently. The THX recommended crossover point is 80Hz, which is what most older receivers use. However, the tapering off--the crossover "slope"--beneath 80Hz can differ. Some receivers taper off more gradually under 80Hz than others. Many newer receivers allow the user to choose among a number of crossover points. Unfortunately, user manuals don't usually indicate the crosssover slope they use. So a degree of experimentation is in order.

Wow thanks John. You're a good man.
By the way I've decided to get the Yamaha 6180 that apparently has an improved YPAO (witht he mic for calibrating it). I'll let you know how it turns out when I get it in a week or two.
I have a feeling it may still be better to get the sound level meter out and use that but we'll see.

Nothing beats doing it yourself, if for no other reason than being reassured that it's done right.
My Onkyo receiver has a built-in calibration scheme with its own microphone, too. But I'd rather set up the speakers--the right height, right spacing--measure the distances and then set the delay times and the volume output levels myself, using a sound meter. Then jot down each of your settings for later reference and/or further tweaking.

I really like my sub! It delivers those low freqs my old sub didn't. It really rounds my system out. I have it sitting right beside my couch. We hear and feel every frequency
! No phase switch but other than that I am really happy with it.
This thread has been very informative and I think I am going to keep the treble at+2db, down from max +6db and let myself adjust to that Then see I any minor + or - is needed.

Hey John,
THX reference spec is actually 85Hz, but who's counting. Most equipment is actually produced with 80Hz in mind. If you are tweaking your system it is best to use a SPL meter calibrated to 75Hz. Avia and DVE are set with reference tones of 75Hz. Use the DVD's via AC3/ DD 5.1. Avoid the Pink Noise. That pink noise associated with most Amps is actually 85Hz, especially the THX certified peices. Problems can arise when calibrating your speakers at the range of sound. Usually you will find that most LFE channel may appear to be hot. Flat Eq's are always recommended when setting the level output. I always adjust the gain output higher on the LFE channel, and have lower volume setting on the sub to acheive the 75HZ crossover setting on the sub. Did I just confuse you guys... It is always important to keep the 45 rule in place from your sweet spot. 45 degree balance between you front channels, poiting that 45 degree radius on the sweet spot. THX is hocus pocus for the rich and the those that spend stupid money on HT. Just becasue it is one man standard doens't make it standard for the rest of us. You be the judge of what you system sounds like. Everyones taste is different.
