Around 8 years ago a friend of mine bought a pair of speakers that supposedly came from the experimental laboratory of Joachim Gerhard. The speakers he bought were based on the cabinet of the big 2 way speaker Sonics Arkadia. The Sonics Arkadia originally used Seas CA22RNX eight inch woofers and Seas 27TDFC tweeters.
There was a long thread on a german forum in which a user pimped the cabinet and developed new crossovers for his Arkadia that contains many photos for the ones interested: http://www.hifi-forum.de/viewthread-205-485.html
The experimental version my friend bought contained a Seas Excel Nextel woofer and a Seas DXT tweeter. Very interesting! Unfortunately „out of the box“ they wouldn´t play right (basically the crossover parts were glued to the back of the cabinet and it was clear that it was an experimental setup). The friend did me a favor and I wanted to thank him by helping him to get the speakers to play right. After some research I found out that the well known german DIY speaker designer Udo Wohlgemuth offered a kit that used the same drivers in a similar cabinet format called Excel 22 DXT. I bought the plans and crossover parts for my friend and he built and installed the crossovers but somehow lost interest. Fast forward to today I did the friend a favor and he gifted me the speakers.
I started this thread to motivate myself to get them done. I have no background or experience in DIY, so this will likely be a slow process. I have an Umik-1 mic and plan on doing some rudimentary measurements „as they are“. I will try to get the plans from the friend in the next week or so. The total price paid for the pair of speakers, the building plans for the Excel 22 DXT kit and the crossover parts were around 500€. Today one of the woofers costs around 330€.
Any kind or motivational words are appreciated! Please be patient, since this project will most likely be moving at a slow pace.
This is the pair I got compared to the Elac DBR62. Pretty big speakers!
