Greetings All,
Quick history: new to the forum (been lurking for a while), but have been repairing/building speakers as a hobby for a while. I have a real interest in audio equipment, as it feeds directly into my love of music. I mistakenly decided to try and upgrade a pair of my grandfather's Audio by Fisher speakers with new components. I was looking for more accurate reproduction and clarity than the "vintage" speakers could. Due to incompatible crossovers, the result was lackluster. It was painfully obvious in retrospect that I should have considered the drastic differences in response compared to the stock 1970's speakers (not to mention crossover points, enclosure dynamics, and just about everything else). I decided to harvest the new speakers I had purchased for a complete build. The TriTrix design seems to fit most of the size, performance, and aesthetics I was looking for.
Here are the differences:
1) DSA135-8's vs. DC130BS-4's (similar response, with a resistance difference)
2) DC28FT-8 vs. DC28FS-8
3) Custom or Dayton 2-way crossover to account for the woofer resistance differences
From what little I know about crossovers, it looks like the stock TriTrix uses a 2nd order with some resistance compensation or attenuation? Maybe?
I'm familiar enough with fabrication techniques to fit the drivers and build the cabinets. I need assistance with the crossover. I'm considering using the Dayton premade 2-ways at anywhere from 2.5K Hz to 4.5K Hz. It's either that, or I try to build a custom crossover. I've used a few of the on-line calculators to see what I'm in for. However, my lack of experience and knowledge with regards to design will likely lead down a similar path, where I'm not pleased with the results after considerable effort.
If anyone could help me decide on an existing crossover, or to suggest changes to the specified crossover, I'd really appreciate it. I'll be forced indoors over the winter, and I'd love to have this project on the road to completion before the snow flies.
Thanks in advance for the help.
Jason
