-is it likely to be slowly shaking the guns out of alignment in a PRTV?
this may be a stupid question, but everybody has told me these things drift over time, so will playing a lot of bombastic tracks just hasten this?
now that the systems correctly set-up, i'm having a fine old time cranking it up, but wondering about the side effects of doing this to often.
just how sensitive is the interior circuitry/alignment of the average RP?

That is something I've never considered before. I have two Def Tech PF15TL subs and they do PLENTY of room shakin' so I'm very interested to know if they will knock my cannons out of alignment. Very good question ckolchak.

It's a very good question. My old boss had two Infinity stacks that each housed four 12's.
They shook the lamps in his projector out of alignment quite regularly if turned right up.
About your situation though, I will be very interested in the answers people put here because it's a question I would have asked sooner or later too. :)

hey, thanks man...i'll have to return the favor someday.
does this mean i've stumped the DVDTalk Yoda's?

I wonder - does anyone here work in the RPTV industry? Testing maybe?
If so, could they "estimate" how much impact is required to mis-align the guns.
Also how about the long term effect of a regular vibration of xxx in/sec^2?? I'm going to guess they probably do not test this aspect and worry only about impacts.
Then, anyone wondering could measure their vibrations, peak accelerations, etc. Providing they have access to vibe meters, accelerometers, etc.
I would imagine it would depend on wood vs. concrete floor, floor consrtuction vs. wall construction, etc.

Wow! I would imagine that it would take a LOT of vibration to knock those guns out of alignment.

I would be more worried about knocking my own ears out of allignment? Sounds like it is getting pretty loud in some home theatres. . . . Be careful.

As the owner of a set-up with six powered subs, and the owner of an RPTV, I can't say that watching movies has increased the amount of misalignment of the CRTs on my 61" Toshiba. I usually do a quick check with Avia every month or so, and as soon as I can get a hold of an ISF tech in my area (another side effect of 'country living'...A/V hell), I plan on getting an ISF calibration done on the 4:3 Toshiba.
It really depends on the movie you're watching as far as the amount of low frequency bass, and what's getting shaken up. The majority of today's films feature what many consider 'bass', mostly hitting around 35Hz or so, or below 30Hz briefly...this isn't what causes furniture to move (or CRTs for that matter). It's the few discs out there that prominently feature the bass in the low end of the spectrum (around 20Hz) for extended periods of time that does the deed. <b>The Haunting dts</b> and <b>The Phantom Menace</b> are two that stand out. If you have heard the pod race scene on a capable set-up...my god, it's exhilirating. But to be honest, most folks don't have the capabilities to hear these frequencies, or the desire to listen at reference level.
