This is the first veneer attempt I've done so it was really a wing and a prayer. I'm really not sure what your question is about the seams. I'd like to answer you, but not sure what to say.

Getting very close to the final crossover settings. Using a pair of Sennheiser HD580 headphones as a reference and that makes it a lot easier to dial in.

I've had some time to work the crossover and really get an idea of how these things work in the room. This has been a pretty steep learning curve but well worth it.

What I've found is speaker design is two fold. How do you design a we'll integrated speaker system where all the drivers work together, and then and just as important, how does that integrate with the room.

I've heard that second part from respected designers in the past and I just didn't have an appreciation for how important the room is until now.

The biggest obstacle for this system has been room interactions. There is a wicked bump at 90hz and null at 70hz that no matter what I do with crossover tweaks or EQ effects the over all feel of the system. The other part is I am not able to move the system, nor where I sit enough to make any appreciable difference. Also, I am interested in possibilities of speaker design modifications to minimize room effects rather than jump into adding room treatments.

Not that I am against room treatments. I am not. What I do want is a design that minimizes the need for them and then see if they are needed at all.

I'm going to start a thread about designing for room interactions that I hope will help me finish this design and have it integrate with the room better.

Here are the latest frequency graphs. All are done at 1 meter.

The first is with 1/6th octave smoothing and the latter are all 1/48th octave smoothing.
