Yes, I agree that the large, gaping maw does indeed bleat less than other ported subs that I've heard. My disappointment arose from the fact that I even heard it bleat at all.

Yup I hear you. Though if you are hearing ports that's an indicator you need more woofage. Duals baby duals!

I don't make a habit of listening to 20Hz tones very often .

Just reminded me of a week-old anecdote. One of my girlfriends has a 14-year old son who's a pretty good organist (he's going to some European contest in September). They were home about 10 days ago and he spotted my SACD recordings of Bach's organ music (excellent recordings with Knud Vad) and he managed to convince her mother to stay to listen to one piece he selected (BWV542).

Well... he was expecting to hear "nice sound" and mostly intended to evaluate Vad's play... He was FLOORED. We listened at -6db on receiver (which means that a 2-hands+pedals chords reaches about 108-109db). He looked like a zombie for a while. He had never thought possible to have a pipe organ so closely reproduced in a home system. (good multi-channel recordings are killers with pipeorgan). On top of the proper church reverb of the multich, he was astonished by the reproduction of the lowest notes from the pedals coming out of the EP-500.

Now my main problem is to fence off requests for seconds... (I am not THAT interested in the mother! ).

OK, that was my 20hz, 2-cents!!

. I bet your neighbors loved you.

You must be assuming a greater skill level than I have with the software. After 90 minutes messing with it today, I gave up. I was able to get it to register the readings from the SPL meter within the program, but every time I tried to "measure" and record the curve, I get a straight vertical line somewhere below 20 hz showing about 45 db. It's just the same line after multiple measurements, so I decided to throw in the towel for today and try again later this week.

Any advice on something obvious I'm doing wrong? When I have the program open and click the red round button to turn on the SPL monitoring, it accurately follows the measurements of the SPL, but for some reason, when I actually go to measure, I can't get any results that make sense out of it.

When that didn't work, I did do some manual measurements with the SPL meter and the Real Traps test tones and came up with this chart. This is probably not terribly useful as I wasn't able to do a smooth "sweep" curve, these are just points plotted on a curve. (20,25,30,40,50,65,80 hz). If these results are to be trusted, there's a pretty hard dip at 50 hz.



I'm going to keep experimenting... The other thing I've been considering is putting the EQ sub back into the mix and running duals, but the EP600 makes that setup extremely difficult as as soon as it is hooked up to the Denon and another sub is added to the chain, the required gain settings on both subs completely change. I haven't done much testing with 2 subs, but it's on my list of things to test out in the next 30 days.

Randy, I remember reading your posts and hearing your frustration when you added the 350s awhile back and now understand even more what you were going through.

Jason

Don't even bother trying to hook up another sub to your Denon when the 600 is running. Remember the thread about the 600's low input impedance? The Denon can't supply dual subs because of that issue.

Do you have a wall-to-wall distance of 10 feet somewhere? Take it out and that will solve your 50Hz problem .

Since I received my new amp Mojo, I am successfully running the 600 and two 350's via the Denon with no problems.

Really? The 350 output doesn't get attenuated when the 600 is plugged in?

I'll have to experiment again, but my current settings seem more realistic.

Before, with my previous 600 amp in the loop, I had to have the Denon on -10 to -12 dB's, the 600 on the lowest setting, and the 350's gain at about 3/4 of MAX.

Currently my new 600 is around 7 o'clock and each 350 is about 1/2 way or 12 o'clock. The Denon is on about -2dB currently.

I'll see what happens when I try unplugging the coax line in from the 600. Before my 350's would jump way up in spl.
