The walls are probably not braced.

When you get down to it, the biggest change about a new pair of Ks from a vintage pair is the crossover. The MDF is nothing but a bunch of BS. It's simple. That was not instituted for an imprvoment. It was a cost reduction. Plain and simple and spun to be a better box for all of us. I think at most a very slight incremental improvement. Drivers and horns mostly stayed the same. So the bottom line to the OP is that YES it is very easy to mod an older pair of Ks and have them sound far better than

The software I use is TRU RTA. There are others as well that are good or better. This one has been easy to use and useful to me. You also need a mic and a power supply for it, (also referred to as a phanton power supply). For that I have a cheap but accurate Behringer mic, and Behringer mixer which contains a phantom power supply (roughly $120 for both). You also need to have a soundcard in your PC. Basically the software will drive tones, sweeps, pink noise, etc through your system and capture the

Another comment that will surely piss some off, but it's just my opinion. Audyssey (or however it is spelled) SUCKS for music. It is nothing more than a DSP trick and does not belong in 2 CH systems. It is a HT tool, again IMHO. That is why it is found in AVRs and not 2 CH receivers. I have it in my AVR that I recently purchased. It works pretty well for Home Theater and gives that "engulfing" and reverberating effect, and can balance that within the room so it sounds kinda like that

Audyssey is for multi-channel systems but it will create filters for 2-way as well. I never tried to use it for just bass. I'm not sure you can do that.

[quote user="AletheiaAudio"]" Mark has clearly gone to the dark side, and visual representations of the sound are what you need when you can no longer hear anything. For crying out loud, look at what he subjects his hearing to. [/quote] Dean, pretty funny! But I'll be serious now. I have a ton of respect for what you have brought to this forum over the years. The few speakers I have left in my house with passives have YOUR passives because over the years my rather particular ears

I wasn't sure so I was being careful. Keyboards suck. You never really know how someone would be saying the words.. I never heard a CW-III but the build pics looked nice how they mated the parts. It sounds like the OP does not like his speakers which is fine. We've all changed 'em in and out.

I seriously doubt that you would be able to actually hear the difference between 3/4" and 1" plywood boxes.

Does everyone here think that bracing the cabinet or stiffining it will change the sound of the speaker..........because I definitely don't. It MAY produce a TINY bit more energy that was getting lost. I bet you couldn't hear the difference. I just don't think it would do anything in my opinion to solve a "bloating" issue, and I would not waste a moment changing the engineering of the cabinet. It will just devalue a beautiful pair of speakers. Since the original poster is well

What I suggested is really easy stuff to do, and a lot of folks on this forum use an RTA (real time analyzer). It presents a visual image of what you hear. You would use "pink noise" not music. You could disconnect the MF and HF drivers to get a curve........but not really required. I highly doubt what you are hearing is a cabinet vibration. That would be a remote possibility on such a new design with all the modeling capability Klipsch has, really. A gross vibration would not get caught
