Is anyone familiar with the JSE INFINITE SLOPE speaker lineup? I have the 1.8 which is about midway in size compared to the other JSE models. They are about 20 years old now with all original drivers. The woofers needed the foam replaced, which I got on e-bay and did them myself. The 4- 10" drivers work perfectly and offer tighter bass after I replaced the foam surrounds. I did blow a tweeter around 1992 and since they were still in business then, I was able to get a matching replacement.

I have used infinite slope speakers for a long time. I love them!!! If you need info on them contact John Sollecito at Source speakers. I have Model 1 speakers right now and had the .8 a while ago. Really good speakers!!!

Joseph Audio is now making speakers using the Infinite crossover technology. I do not remember if they bought out JSE Infinite Slope but they may be able to help.

When I contacted Joseph Audio they said they didn't deal with the Infinite Slope speakers and that John from Sourcespeaker.com did. I just picked up a pair of 1.8A speakers and can't wait to hook them up!!!
