subwoofer set up

danger boy

Ok. I know how to set up the volume for a sub.. but is there some kind of CD/DVD of tones to properly set up your subwoofer for home theater?

I might be having trouble with the crossover and phase issue. How can i tell where to set the phase exactly? I'm thinking if there was a way to set it up better than just by ear.

Yes i have a Radio Shack SPL meter and use it all the time. like I said. the volume is correct. but not sure about the crossover and phase settings.

Oh yeah. I don't have a laptop to do one of those sweep thingys.

Danger Boy, I have been wondering the same thing. Is it possible that you could detect an increase in the dB that the SPL could detect? I was contemplating having someone stand beside the sub, I would sit in the listening position with the SPL and have the assistant move the phase setting slowly at various sub frequencies and do a plot of the dB response for a given frequency tone between 0 and 180 degrees. Anyone tried this?

I have the Avia disk, but I found it just as easy to use the receive test tones.

I have heard many recommend "Finding Nemo" as a DVD to use when testing sub (sound). There is a scene where Nemo is in the aquarium, tapping glass. From what I have heard, that's a pretty good judge.

I really need to rent Finding Nemo so I can try out my new SVS 20-39 PCi Is the story line decent or is it mainly a kids movie?

It's no Incredibles, but it's watchable. I need to rent it too, I love my Omni s-12, but I'm not sure I have it optimally configured.

Nemo is a pretty good movie if you don't watch it too much... it's just as good as the Incredibles to me, maybe even a bit better... movie-wise, but the bass in The Incredibles is a lot better for a sub work out.

Except for "Darla" in Nemo. That'll separate the SVS's from the boys.;)

Well... over at AVS, this one guy was testing all kinds of subs for that scene, I forgot the link/name of the thread, but it's there... and guess what sub came out the best for the darla tapping...... JBL E250P did it flawlessly... lol

That's odd. I've never heard the JBL E250P, but I did consider that sub before I bought the pb10. All the reviews I read did not put the JBL in the same league as any SVS, including the entry-level pb10-isd. I do own a few JBL professional speaker products, so I know they have a great reputation in the pro audio field.

All that I know is that with my sub, "Darla" shakes the living hell out of my living room!

I found the best way was to do the sweep thingie but it might be difficult without a laptop. No chance you have a desktop in the same room?

I enjoyed finding nemo more than the incredibles. The plot is directed to a younger audience but the humor in it makes up for it. There was a thread a while back that had a little competition of what levels people could hit using that darla tap with only a sub running.

Well I should've been clearer, but I didn't mean to impl the E250P was in the same league as an SVS, I only meant that EVEN a JBL E250P can do that tapping scene flawlessly, which means it's not a very good test hehe

Darla is a good test. A JBL E250 wouldn't compare to a PB10 in floor shaking impossible

My brother has a JBL of some sort. The Darla scene sounds o.k. on his setup, but compared to my SVS 25-31, the scene sounds _entirely_ different. One of those things where you won't know what you're missing until you have heard it....or I should say felt it with that scene. The range is simply missing in most subs <$1k, even when they are well tuned and matched with a room.
