Jaybo,the long answer is YESSSSSSSSSSSSSSSSSSSSSSSSSSSS.Single driver and horns and various vintage Altecs,JBL'S,and others are very popular again.The Japanese have been using this stuff for years.They are usually 10-15 years ahead of the US as far as single driver and different horn technology's.It all depends where you ask the question.Check out JE labs site + "Site Jeen" there are many more vintage sites.If you wanted to try a pair on the cheap try the horn shoppe's speakers.If you want any plans for some of the 50's models send me an email.Take care,keith
Are horns and hi-eff designs becoming more popular
I feel they are but wonder what others think? Since today one can build hi-eff designs in most any type of loudspeaker. With many new hi-eff transducers availible. Hi-effs not just front or back horn designs anymore.
