" Room gain is said to be +6 dB. " Room gain is basically a second order (12dB/octave) increase in bass from the point it begins at. Where it starts kicking in totally depends upon the dimensions of the room. Basically it starts at the half wavelength of your rooms largest dimension. So in a 17' room you will start seeing room gain at about 32hz. That is assuming a well sealed room, the more lossy/leaky your room the less boost you will see in the bass. Shawn

" My room is sort of hatchet shaped. A hall enters one corner that is about 18 feet long. " Is that hallway sealed off? If not you won't see very much room gain there since that hallway is extending the longest dimension of your room. What room gain is where the reflections from your walls are becoming more and more in phase with the sound still coming out of your subwoofer(s). The sound couples and you get an increase in SPL throughout the room. Basically the area where you entire

Dave, "Where v=vinyl and d=digital, if v=d, then it only follows that d=v. In other words, an LP mastered from the digital copy of the LP that no one could distinguish from the vinyl would also have to be indistinguishable from either the vinyl or the digital copy. I hope I structured that right." Nope, that is a logical fallacy A = CAR B = Honda Civic B = A (Honda Civic is a CAR) but is the inverse true... does A = B? Nope, not all cars are Honda Civics. To try and boil this down simply

Dave, "I don't know what you mean by "mono rear." The rears were quite separate and the feeds discrete" The basic Hafler extracts a single rear channel of information. Hafler was simply L,R, L+R (center) and L-R (rear). See: http://sound.westhost.com/project18.htm For several different ways of implementing a Hafler setup. The original way is shown by connecting a third speaker to the positive of the L and R speaker. Only out of phase material would be reproduced by it. DynaQuad

Jim, "I used Trifield in a 2 ch system for some time and was always amazed at the results, I'd swear there was a center channel where there was none." I've never tried Trifield with a Meridian configured for just 2 speakers. I'll have to try that some time. Trifield really shines up front when you add a center to the mix. "In the end, I was too ADD to use the Meridian processor as I was always trying different surround effects and then comparing those to stereo," That

"..because the earlier Dolby PL didn't do as good a job." No, it did lousy on music... everything collapsed into the center and it tended to be unstable with pumping/breathing. When you did Hafler were you doing that at speaker level? If so that would be tough to integrate with other processing. "I'd love to hear those sometime. I guess I am just skeptical that they could do a better job than Hafler on 2 channel native material." If you liked Hafler that much there are

" I'll second Meridians Trifield, the best I've heard and the only which would consistently steal me away from 2 ch." Trifield has converted a lot of 2 channel guys into surround converts. It does a nice job, esp. up front. The actual process of expansion was designed for any number of front channel speakers. It would be very interesting to hear it used for >3 speakers but I don't think anything has ever implemented that into a product. I have L7, PLII/PLIIx and Trifield
