Opera Callas loudspeaker
Colleen Cardas strongly urged me to try the Callas loudspeaker from Opera Loudspeakers (whose products she also distributes in the US), which she claimed was an ideal match for the Unison S6 amplifier I reviewed last August. In my experience, the stand-mounted Callas ($5000/pair) is unique among loudspeakers in being the logical contrapositive (inverted and flipped, so to speak) of the usual D'Appolito driver array of midrange-tweeter-midrange (MTM).
Paradigm Atom Monitor v.5 loudspeaker
When folks visit from out of town, they frequently remark that my Brooklyn neighborhood reminds them of "a real neighborhood" from their neck of the woods. "Except that we know all our neighbors and talk to them when we're cutting the grass, watering the lawn, and walking the dog. You probably don't even know the names of any of yours."
Paradigm Atom v.3 loudspeaker
I had mixed feelings about reviewing the $189/pair Paradigm Atom loudspeaker. Although in the past I've been favorably impressed with Paradigm's speakers—the $600/pair Reference">http://www.stereophile.com//loudspeakerreviews/628/">Reference Studio/20 remains one of my favorite affordables—Budget Bob tends to get a bit nervous when a speaker's price drops below $250/pair. In my experience, even when the most talented speaker designers attempt to make a speaker to sell at such a low price, the result is often a very small cabinet with limited bass extension and inferior high-level dynamics.
Paradigm Control Monitor loudspeaker
If speakers were cars, the Infinity IRS Beta and B&W 801 Matrix would represent the luxury end of the mass market, with perhaps the Celestion SL700, Quad ESL-63, and MartinLogan Sequel II analogous to rather hairy, temperamental sports carsthe Porsche 911, for example. But most people don't buy Porsches, or even Lincoln Town Cars; they buy Hyundai Excels and Ford Escorts. In the same way, when the car is garaged for the night, they don't sit down in front of IRS Betas; in all likelihood they listen to their records with a compact two-way design. If competently designed, a small two-way can give a great deal of musical satisfaction, and, to take a current hobbyhorse of mine out for a trot, if a designer can't produce an at least competent two-way loudspeaker, he or she has no business trying to design larger, more ambitious modelsthere's nowhere to hide your lack of talent if all you have to play with is a tweeter, a woofer, a rectangular enclosure, and a handful of crossover components.
Paradigm Reference Active/20 loudspeaker
There are many benefits accruing to a loudspeaker when its designer goes the active or powered route. The usual losses and distortions associated with passive crossovers can be circumvented, while the fact that the amplifiers and drive-units can be designed as a package enables the designer to squeeze more performance from each than would otherwise be the case. And the savings gained from the absence of a separate amplifier chassis can be passed on to the consumer.
Paradigm Reference Signature S2 loudspeaker
Canadian company Paradigm has made a name for itself over the past 20 years with affordably priced, high-performance loudspeakers. Its Reference Series designs have garnered much praise from this magazine—I was well impressed by the floorstanding Series 3 Reference Studio/100 ($2300/pair) last">http://www.stereophile.com/loudspeakerreviews/105paradigm">last January, my review following hard on the heels of Kalman Rubinson's enthusiastic recommendation of the smaller Studio/60 v.3 ($1600/pair) in December">http://www.stereophile.com/loudspeakerreviews/1204paradigm">December 2004, while the bookshelf Reference Studio/20 ($800/pair) has been a resident of Stereophile's "Recommended Components" listing ever since Bob Reina's original review in February">http://www.stereophile.com/loudspeakerreviews/628">February 1998.
Paradigm Reference Studio 20 v5 loudspeaker
I have fond memories of the Paradigm Reference Studio 20. When I reviewed the original version for the February 1998 issue of Stereophile, it was the model that started me on my quest to seek out the best affordable loudspeakers. I believe that of all the speakers I've reviewed, the original Studio 20 remained in the magazine's "Recommended Components" longest. When I checked out the speaker's fourth generation, in May 2008, I felt it had significantly progressed in terms of sound quality and value for money. This didn't surprise me, however, as pushing the envelopes of sound quality and value has long been Paradigm's trademark. They've done with this with every one of their speakers I've heard, including the third and fifth iterations of the Atom (which I reviewed in September 2002 and February 2008, respectively), and the more expensive models I've heard at audio shows. So when I was given the opportunity to review the Studio 20's fifth generation, I jumped.
Paradigm Reference Studio/20 loudspeaker
The least expensive model in Paradigm's Reference series, the Studio/20 loudspeaker is a rear-ported two-way dynamic bookshelf/satellite design, superficially identical to the powered Active/20 that JA">http://www.stereophile.com//loudspeakerreviews/597/">JA reviewed last November. It features Paradigm's 25mm PAL pure-aluminum dome tweeter in a die-cast heatsink chassis, and a 170mm MLP mica-polymer cone in an AVS die-cast heatsink chassis with a 38mm voice coil. The crossover is third-order, quasi-Butterworth, said to be "phase-coherent." It features high-power ceramic resistors, film capacitors in all signal paths, and both air-core and steel-core inductors.
Paradigm Reference Studio/20 loudspeaker
One of the first affordable loudspeakers I reviewed for Stereophile was the original Paradigm">http://www.stereophile.com/standspeakers/628">Paradigm Reference Studio/20 bookshelf model, in the February 1998 issue (Vol.21 No.2). At the time, I felt that the $650/pair speaker was a breakthrough—although not completely devoid of colorations, its ratio of price to performance set a benchmark a decade ago. I kept the Studio/20s around for several years to compare with other bookshelf speakers I reviewed, and they remained listed in Stereophile's "Recommended Components" for several years after that. The Studio/20 is now in its fourth (v.4) iteration, so I thought I'd grab a pair to hear how they compared with current affordable bookshelf designs.
Pawel/Ensemble PA-1 & Reference loudspeakers
Ten seconds to ignition. Relax, buckle in, and welcome to Stereophile's Good Times time machine. Flux capacitors fully energized. Ignition. Not to worry, that slight tingling sensation is perfectly normal. Roll back your calendar to...June 28, 1933. We're at the Eighth Annual convention of the Institute of Radio Engineers in Chicago. Harry Olsen is on the podium, describing a new wide-range cone loudspeaker for high-fidelity sound reproduction.
Quiet, please, Mr. Olsen is about to describe the disadvantages of multipledrive-unit systems. "The radiating surfaces must be separated by a finite distance, with the result that this system will exhibit peculiar directional characteristics in the overlap region where the sound radiation issues from both sources. To reduce this effect to a minimum, the overlap region must be confined to a very small range which requires an elaborate electric filter system for allocating the frequency bands of the units. The greater space required for the two loudspeakers is another important factor. The cost of two separate field structures and vibrating systems will be considerably greater than that of a single unit."
