Some interesting measurements on subs placed near vs far from the listener:

Very interesting - thanks.
This provides incentive to get going and make my two Goldwood 18" H-baffles which were intended for the nearfield vertically under my nearfield Klein & Hummel 0300s.

Well, that confirms my experience with a pair of nearfield monopole subs. My MMG/REL hybrids are in a bedroom. I can lean forward in my chair and touch them. The bass is as perfect as I've ever heard - as if the room has no influence whatsoever. It is my benchmark for the big system.

Hi Russell:

Can you share more about the 18" ob sub? With the woofers being $75.00 each you would think they would sound slow, or muddy?

Thanks Russell:

Only issue to deal with using near field subs is time alignment, but easy to do with phase sweepable controls on most subs as they delay time.

I'll be crossing mine around 60Hz at which frequency the wavelength is around 18' so alignment will hardly be an issue, as they will be more or less the same distance from my ears already and even if they weren't a couple of feet of error would not be particularly audible - we're talking ~40º of phase error at 2' difference at 60Hz.
