When it comes to choosing a speaker ensemble, quality sound options are certainly not in short supply. Unfortunately, this makes shopping around for the perfect match to your ears more difficult than ever. Once you have narrowed down the type of speaker ensemble you are in search of--a conventional floor standing "monitor" or a sub/satellite ensemble the field becomes more narrow, but not necessarily shorter.

I'm all for giving a new company an audition, but I'm also one to choose a line from a manufacturer that I've had good past experiences with. Chances are if you've owned a hi-fi or home theater system in the past 20 years then you've heard of (or owned) Infinity loudspeakers.

Over the past several years, Infinity has grown in size tremendously. Today they offer a virtually unlimited selection of speakers for the home and car. What this means to the end user is that through Infinity's sales volume, advanced developments inevitably trickle their way down into entry level offerings, creating even greater value to the end user--you.

Unique Features
What strikes me the most about the Infinity Entra ensemble is that the speakers appear both simple and elegant--two qualities not often found together. The front baffle of each speaker, including the subwoofer, has a beveled edge that creates a distinct appearance. Where this beveled edge actually plays a role in the application of the speaker is with the optional sidewall-mounted OWS-1. The OWS-1 is best described as an on-wall, in-wall. It is a 2-way speaker featuring a 5 1/2-inch mid/woof and 3/4-inch C.M.M.D. (Ceramic Metal Matrix Diaphragm) tweeter in a relatively narrow profile--just under 5 inches. This design is one of the best I've seen in terms of effectiveness for side-channel surrounds without having to be cut into the wall or intruding on the listening area.

There are several options in the Entra lineup. I chose the conventional floor standing Entra Three as my main L/R and the Entra Center Two as the center for this review, also opting for the inclusion of the Entra Two 12-inch 250-watt subwoofer. All of the speakers in the Entra line-up (except the sub) are magnetically shielded. The Entra Three towers consist of 38-inch tall, 8.5-inch wide, 12.75-inch deep enclosures with a pair of 6.5-inch C.M.M.D. mid/woofs and a single 3/4-inch tweeter. The Entra Two center channel features dual 5.25-inch C.M.M.D. midrange flanking a single 3/4-inch tweeter in a 7.5-inch by 7.5 inch by 20-inch wide enclosure.

The 12-inch, rear ported subwoofer boasts an impressive 250-watt amplifier complete with high and low level inputs, variable crossover, 0 to 180 degree phase shift and gain controls. Weighing in at 47 pounds, this hefty brute uses the larger 12-inch C.M.M.D. subwoofer, the power of the amp and its efficient design to bellow tunes in the 30Hz range and yet will remain responsive up to 100Hz without missing a beat.

Installation/Setup/Ease of Use
Unpacking will take you more time than actual placement with the Entra lineup. The OWS-1 side-channel surrounds require four simple drywall screws (no need to anchor them) and include a template for accurate installation.

The height of the Entra Three towers create excellent on-axis response for the listener. They sound best placed out in front about 8 feet apart and canted slightly inward.

The Entra Center Two is large and a bit awkward to place because it
has no base to allow for positioning. Being heavy adds to the awkward
installation. Of course, this can easily be overcome by simple
ingenuity but, at $319 retail, I expect more.

The Entra Subwoofer is more than capable of making up for poor
placement through its power, phase shift and other user-friendly
characteristics. No need to fuss about moving furniture with this one.

Final Take
I was lucky enough to get to spend several weeks with the Infinity
Entra ensemble. This gave me plenty of time to try it out with various
receivers and pre/pro-amp combos I had in for review. A clear
conclusion: the Entra ensemble sounds best with lots of power behind

Starting first with a Marantz 7200 A/V receiver, I was impressed
with the huge and full soundstage they created. The Marantz yields an
impressive 105-watts per channel and is worthy of driving such a large
ensemble. The various size C.M.M.D. drivers in the Infinity Entra
ensemble are well matched through quality internal crossovers and there
is not one speaker that does not sound natural.

Through subtle dialogue passages I was able to get an ear for the
Entra Center Two. It has a relatively flat response and will take some
getting used to if you tend to like brighter sounding speakers. This is
not a flaw by any means, but more an accurate rendition of dialogue.
Another impressive characteristic of the Center Two was its ability to
handle large explosions on screen--aided of course by the two flanking
Entra towers with plenty of mid-bass.

That mid-bass also compliments the subwoofer, as it does not have to
reach up so high in the frequency range to close the gap between the
highs and lows. The impressive mid-bass of the entire Entra ensemble
makes it an excellent candidate for those of you who enjoy listening to

The large 12-inch subwoofer really packed a punch on low passages
and did not show any signs of fatigue. Though I did prefer to turn the
subwoofer off when listening to music in 2-channel and cut it around
80Hz during DVD-Audio playback with minimal gain (volume).

If you're looking for an ensemble that is well matched, relatively
inexpensive and delivers an outstanding performance for movies and
music, then I recommend giving the Infinity Entra ensemble a listen.
Though there are several options regarding cabinet size in the Entra
lineup, you must also consider the power requirements when auditioning
the Entra ensemble tested here. While it may be an efficient speaker,
you will not fully utilize its potential without investing in a
formidable amplifier.
