The Rega, ELA uses a quarter wave transmission line. To improve airflow through the fold in the transmission line, a full radius section is fitted into the base of the Ela cabinet, resulting in smooth, uninterrupted airflow.
Have heard a lot of speakers but never these Regas... they are the closest thing to a set of LS3/5a that I've heard and for a FRACTION of the cost and... with a built in stand!! They are nothing short of astounding. In terrific overall condition and the 2nd set of ELA from the Richard K collection. These are the most desirable "series one" version using Ruark bass drivers. Owning two sets of these ELA proves emphatically that man knows his hifi. These little rascals are winners on every level.
Rega, ELA Series One floor standing speakers: $399 plus applicable sales tax
Due to its particularly even bass response the Ela is unusually insensitive to room positioning. The speakers can be placed up to 50mm from a rear wall, in corners or away from the walls. The angle of the speaker is not important. Both loudspeakers can be placed at different angles or in different positions. - Ela 2000 product description from Rega
Natural, musical, agile, presentation – tidy, deep bass, though insufficiently punchy for liveliest rock. Unfussy about room placement. - What Hi-Fi Buying Guide, Oct 1992
