Stand Loudspeaker Reviews

The first I heard about Elac's new Debut line of speakers was from two 12-year-olds at T.H.E. Show Newport Beach 2015. "Elac's room is making the best sound at the show," they said.

Elac? I thought. I have an Elac Miracord 40A turntable. Hmmmm...

So I walked to Elac's room and listened to the Debut B5 bookshelf speakers ($229.99/pair). I was impressed—but maybe not as impressed as everyone else in the room seemed to be. In the halls, people were raving: "Did you hear Andrew Jones's new speaker?" Show bloggers went crazy. People kept asking me, "Herb—what'd you think of the Elacs?" My polite response was always, "I'm glad I'm not in the business of making $1000/pair speakers."

There is much to admire and to enjoy in this idiosyncratically charming hybrid loudspeaker. Eminent Technology has been around for about 25 years. Founder Bruce Thigpen was a pioneer in air-bearing technology, and ET's first product was a well-regarded air-bearing tonearm. The company later developed and was awarded patents for its Linear Field Transducers (LFTs): push-pull">http://www.stereophile.com/floorloudspeakers/308et">push-pull loudspeaker panels that operate on the magnetic rather than the electrostatic principle. Arraying magnets both front and rear of the plastic-membrane diaphragm eliminates a problem inherent in many planar-magnetic designs: as excursion increases, the magnetic restorative force diminishes. As can be expected, this technology is not efficient at reproducing bass, so most such speakers have been hybrids.

"I'm intrigued how Emotiva can offer an active speaker for so little."

This was John Atkinson's response to my request to review Emotiva's Pro Airmotiv 4s ($299/pair). My colleague Steve Guttenberg had been discussing this speaker with me at a recent industry event, and I'd realized that it had been some time since I'd reviewed an entry-level loudspeaker. I'd reviewed Emotiva's X-Ref XRT-5.2 floorstanding speaker in the August 2012 issue and had been impressed with its combination of sound quality and price. I requested samples for review.

The two-way Energy CB-10 ($269.99/pair) is a bass-reflex design. A large rear-firing port has an internal diameter of 2" and flares out to 2.75". The speaker uses a 1" aluminum-dome tweeter and a 5.5" woofer with a ribbed elliptical surround, the latter said to increase excursion, decrease distortion, and create a larger piston area for greater efficiency, making the CB-10 an easy match for amplifiers. The CB-10's frequency range is listed as 66Hz–20kHz, its in-room sensitivity as 90dB, and its nominal impedance as 8 ohms. In Energy's Convergent Source Module design, the tweeter and woofer are meant to act as a coincident source working together to provide wide bandwidth, constant dispersion, and a flat frequency response. In theory, this would all add up to easy setup and satisfying listening from anywhere in the room.

I've long kept an eye on Michael Creek's loudspeakers (Epos) and electronics (Creek). He's always moving forward, with either updates of current designs or a revamp of an entire product line. And though I've found that many of his new-product ideas tend to feature evolutionary rather than revolutionary sonic improvements, I've found that they always represent excellent sound quality for the dollar in an increasingly competitive marketplace.

Roy Hall has his famous Music Hall MMF (Make Money Fast) turntables made for him in the Czech Republic.

Roy has also long been associated with Epos Limited, since a chap named Robin Marshall started the company in 1983. Their first product was the ES-14 loudspeaker, followed by the smaller ES-11. Both were largish, stand-mounted models, and both offered a lively, expressive, unstuffy sound. The speakers have always been fun to listen to, even if they lacked—and still lack—the refinement of some far more expensive speakers.

Americans might be forgiven if they haven't heard of Epos. A small, British specialist loudspeaker manufacturer, it was founded in 1983 by its designer, Robin Marshall—an ex-BBC engineer and a onetime consultant to Monitor Audio, according to Roy Hall of Epos's US importer, Music Hall. Their first model, the ES 20, didn't make it to the US, and was apparently a bit too pricey in the UK to make much of a splash there (about £700, $1300 at the current rate of exchange—a mint in a country with the patent on sub-$500/pair (UK prices!) two-ways). In 1986 or thereabouts, the new, smaller ES 14 was introduced, using updated versions of the same drivers in a smaller, ported cabinet. Music Hall only recently began importing the Epos into the US.
