My History with Babb by David Chaffey:
I had seen some advertisementss for Babb speakers for several years. As a "full-range" marine speaker, I did not pay much attention, after all, I was an "audiophile" and marine speakers were beneath me. Boy was I stupid! Then Alan developed the Lorelei as a 5” speaker that covered the range of 30Hz to 20kHz. I saw the ad in Speaker Builder or AudioXpress. It was crazy expensive, buy my curiosity got the best of me and I had to try it. At the time (about 2002) they were $835 for a pair. “For a limited time” Alan was offering a free cabinet with it.
I got a pair…They did some things better than any speaker I had ever heard. They were not without their challenges, but worth the tweaks to figure out how to get the most out of the beast. I friend in Texas also had a pair and we communicated on cabinet ideas to get the most bass, mid-range clarity, etc. from the speaker. It was a bear to load in a cabinet. I know the design idea for the speaker was to make it cabinet neutral, but it seemed to be the pickiest speaker I had played with in over 25 years of design work. I tried a semi-transmission-line the friend in Texas recommended and it seemed to be the best yet, a bear to make, but worth the effort.
In between cabinet experiments there were issues with some noise in the voice coil. The original bearing was Teflon and there was a rubbing noise at low levels. The speaker went back to Alan a few times for a re-build and in between we discussed the Lorelei, its parts and construction. I suggested ferro-fluid as it had become readily available. The last version had the ferro-fluid instead of the Teflon – noise gone! I built a 1/8 wavelength T-line cabinet for it and lived with it for a few years.
