results in radical changes in timbre as you move from one end of the couch to the other (and closer to either the woofer or the tweeter).

The one decision you have to make with these speakers is the setting of the treble level switch, which has positions for – (cut), 0 (flat), and + (boost). But unless you’re putting them in a room with no absorptive material at all — not even a carpet — I strongly recommend the + setting. The S-IW871L also has a bass cut switch that can help in fine-tuning the low frequencies.

Ifirst tried both the S-IW571L and the S-IW871LR as stereo speakers without a subwoofer. I then used them to create a home theater system with three S-IW571Ls up front and the two S-IW871LRs as surrounds; I alternated between Sunfire TS-SJ8 and Proficient Audio PS12 subwoofers.

MUSIC & MOVIE PERFORMANCE Sometimes a particular CD track or DVD chapter practically defines a speaker for me. That’s definitely the case with the S-IW571L, through which I played Iggy & the Stooges: Live in Detroit over and over and over again, courtesy of the Netflix streaming built into my LG Blu-ray Disc player.

region seems barely present, even with the treble switches set on +. This characteristic de-emphasized percus- sion instruments that are especially high in frequency, such as splash cym- bals and cabasa. Despite the upper treble rolloff, the stereo soundstaging was some of the best I’ve heard from in-walls. Sounds stretched to the far left and right of my room.

The S-IW571L and S-IW871LR sound similar, as you might ex- pect. I preferred the S-IW571L because its reproduction of voices is a little smoother; the S-IW871LR’s big 8-inch woofer doesn’t blend with the tweeter as evenly as the S-IW571L’s 61/2-inch midrange/woof- er does. The S-IW871LR does deliver deeper bass, though.

You kinda have to figure any speak- er that can handle the Stooges should play movie soundtracks with ease, and the S-IW571L certainly does. What proved especially compelling to me was its treatment of dialogue. I threw on DVD after DVD trying to find an ac- tor whose voice would bring out the bad side of this speaker, but I couldn’t find a single one. Even Danny DeVito’s dialogue tracks on the children’s mov- ie Matilda sounded smooth and clear; through many speakers, his voice in

Technically, the material is mediocre: video that’s barely better than VHS and a two-channel Dolby Digital sound- track. But this 2003 performance, like these speakers, is relentless and engaging; the S-IW571Ls sounded fantastic pumping out the Stooges’ visceral rock & roll. Although I expect- ed that the voice of a frantic, scream- ing, ecstatic 56-year-old man might

this movie takes on a harsh, nasal to- nality.

When I tried pushing the S-IW571L to its limits with action movies, I heard some distortion, but it wasn’t the ear- straining distortion one usually hears from speakers — it was more a sense of sonic confusion. With a subwoofer added to take over deep-bass duties, both the S-IW571L and the S-IW871LR

Mounted in a wall, both the Pioneer Elite S-IW571L and the Pioneer Elite S-IW871LR deliver smooth bass and mid- range response but exhibit some anomalies in the tweeter range; both show a broad dip in the range from about 7 to 12 kHz.

Off-axis response is fairly consis- tent out to 30° off-axis with both speakers. Both deliver fairly strong bass response between 40 and 80 Hz — average output at 10% distortion or lower is 88 dB for the S-IW571L and 93 dB for the S-IW871LR.B.B.

push any speaker into harshness and distortion, the Elites treated Iggy Pop with far more care than he ever lav- ished on himself.

As I explored gentler music (a cat- egory that includes almost every other recording ever made), I noticed that the Elites were just as kind to ev- ery other singer, from smooth-voiced Holly Cole to the raspy tones of Ron Sexsmith. I have heard few speakers sound so good with such a wide range of vocal styles.

One unusual aspect of the Elites’ performance is that the upper treble

»BOTTOM LINE

I can’t say for sure that the skunk-works approach works miracles — after all, I’ve heard plenty of great speakers designed by big corporate engineering crews. But these Pioneer Elite in-walls conjure a certain magic that runs counter to the usual mass-market priorities of a worldwide manufac- turing conglomerate. They may be somewhat shy in the upper treble, but both the S-IW571L and the S-IW871LR generally deliver smooth, satisfying, kick-ass sound that’s a joy to experience hour after hour, day after day.

S-IW571L, S-IW871LR specifications

The Pioneer S-IW871LR and S-IW571L are high-performance in-wall speakers designed to deliver exceptional audio quality in a discreet manner. These models are ideal for home theater systems, multi-room music setups, or any audio application where space is a concern without compromising sound quality.

The S-IW871LR is a part of Pioneer’s premium line of in-wall speakers. It features a 8-inch high-efficiency woofer that provides deep, rich bass and a 1-inch soft dome tweeter that offers pristine high-frequency response. This combination ensures a broad frequency range that accurately reproduces music and sound effects in movies. The speaker integrates advanced technologies to minimize distortion and enhance clarity, resulting in a balanced soundstage. With a recommended power handling of 50 to 150 watts, the S-IW871LR can handle a variety of audio content, making it versatile for any entertainment setup.

On the other hand, the Pioneer S-IW571L is an exceptional choice for those seeking a smaller form factor without sacrificing sound quality. It employs a 5.25-inch woofer and a 1-inch soft dome tweeter as well. This configuration allows it to deliver clear mids and highs, while still providing adequate bass for smaller spaces or secondary listening areas. The S-IW571L is rated for a similar wattage handling capability, making it suitable for a range of amplifiers.

Both models boast a seamless installation process thanks to their mortar box design, allowing them to blend seamlessly into any room. The speakers come with a paintable grille, providing an additional layer of customization for homeowners who wish to match the speaker to their interior decor.

One notable feature across both models is the use of a high-quality crossover network, which optimally divides the audio signal between the woofer and tweeter. This results in improved efficiency and minimizes unwanted frequencies, ensuring that every note and detail of the audio signal is delivered with precision.

In summary, the Pioneer S-IW871LR and S-IW571L offer state-of-the-art audio performance, robust design, and aesthetic flexibility, making them excellent choices for anyone looking to enhance their audio experience while maintaining a clean and uncluttered living space.
