In today's rush to crank out new models, it's refreshing to see some steady benchmark pieces of gear. The speaker world has its share of stalwarts -- in no small part due to its high-end audio roots -- and Acoustic Energy's AE1 qualifies as one of those long-time references. We remember reading about the AE1 back in the late 80's, and the model is still in existence today (albeit in a Mk III iteration). To celebrate this continued success, Acoustic Energy has made up a special edition batch of 100 pairs of the speaker, appropriately dubbed the AE1 Mk III SE. It features a laundry list of audiophile features, like a steel-lined 18-mm thick cabinet, 110-mm aluminum mid-woofer, 38-mm ring-radiator tweeter and a crossover constructed with top-shelf parts. Available in a variety of finishes for a no-kidding, audiophiles-only price of $5,000 per pair.
