Monolith by Monoprice Encore B6 Review: Big, Warm Sound With Honest Trade-offs

Introduction

A bookshelf speaker that leans warm instead of bright is a genuinely useful thing to own in a small room, and the Monolith by Monoprice Encore B6 fits that description closely. It pairs a 6.5 inch woofer with a 25 mm silk dome tweeter mounted in a large waveguide, and it sells for around $179 per speaker. What stands out after living with it is not surgical detail. It is scale: a wide, deep presentation and a generous amount of low-end weight from a cabinet that gives little indication of either.

This review covers what the Encore B6 does well, where it holds back, and which listeners are most likely to be happy with it.

Who the Monolith by Monoprice Encore B6 Is For

The Encore B6 is aimed at listeners who value presence over analysis. If your priority is a full, room-filling sound with a bass foundation you can feel, this speaker delivers that at a price where many alternatives sound smaller and thinner. It is also a sensible pick for anyone who finds bright tweeters tiring over long sessions, because its top end is deliberately relaxed rather than forward.

Home theater use is a natural fit as well. Because the midrange carries plenty of weight, dialogue stays intelligible even when a center channel is absent and the front pair is handling the full mix. Listeners who want every layer of a recording separated out, however, will find the Encore B6 trades some of that transparency for body.

Design and Build Quality

The driver complement is straightforward: a 6.5 inch woofer handling the lower registers and a 25 mm (0.98 inch) silk dome tweeter set deep inside a substantial waveguide. That waveguide is the most distinctive element of the front baffle and does much of the work in shaping how wide the speaker sounds. The cabinet is rear ported, so leaving a little space behind it helps.

Frequency response is rated from 49 Hz to 20 kHz, with the drivers crossing over at 1200 Hz. The tweeter’s high-pass filter uses an 18 dB per octave third-order slope, while the woofer’s low-pass is a 12 dB per octave second-order design, a combination that keeps the tweeter well protected from lower frequencies.

Finishing is more generous than the price suggests. The top and bottom panels carry a piano gloss finish, and the back is wrapped in a wood-grain vinyl. The five-way binding posts accept bare wire, spades, pins, or banana plugs, so cabling is not a limitation.

Soundstage and Imaging

This is the Encore B6’s strongest quality. It throws a stage that is both wide and deep, and instruments occupy clearly defined positions rather than blurring together. Complex mixes hold their separation, and the speaker moves material between the left and right channels smoothly without any fiddling with placement or toe-in. It stops drawing attention to itself as a box and leaves the performance sitting in front of you.

That behavior is unusual at this price. Many affordable bookshelf speakers need careful setup before they image convincingly, and some never quite manage it. The Encore B6 does it out of the box, which makes it easy to recommend for listeners who care about a believable sense of space.

Bass Quantity and Overall Tone

Low-end output is the other headline. The Encore B6 produces a large amount of bass for its size, enough that on bass-heavy material you may catch yourself checking whether a subwoofer is running somewhere in the room. It is not the fastest or most articulate low end available, and dense passages can turn slightly muddy, but the quantity and physical impact go well beyond what the cabinet dimensions suggest.

The overall tone is warm. There is real weight through the midrange and a chest-level thump on rhythmic material that makes music easy to connect with. Anyone familiar with the ELAC Debut B6 will recognize the character, because the Encore B6 sits in that same relaxed family of sound.

Mid-range and Treble Character

Midrange clarity is where the speaker gives ground. Voices and instruments carry plenty of body and presence, but fine detail and low-level texture are slightly veiled, and there are occasional resonances on piano and similar material. It never reaches the point where dialogue or lyrics become hard to follow, yet it is a step behind the most detailed speakers in this bracket.

The treble follows the same pattern. Cymbals sit further back in the mix than many listeners expect, and their decay does not hang in the air the way it does on a brighter speaker. The published frequency response chart shows a rise above 10 kHz, but that lift is not obvious in listening, and the top end stays polite rather than airy.

Amplification and Setup Notes

Efficiency is rated at 85 dB with a 4 ohm impedance, which means the Encore B6 is not an easy load. It rewards an amplifier with genuine current delivery rather than a low-powered budget unit, and it can sound flat and constrained when it is underfed. Give it adequate amplification and a little breathing room behind the rear port, and it performs noticeably better.

Buying Advice

At roughly $179 per speaker, the Encore B6 makes sense for buyers who know what they are getting. You are paying for scale, bass weight, and imaging rather than for detail retrieval. Listeners moving up from small satellite speakers or a soundbar will hear a dramatic change in the size and physicality of the sound, and anyone sensitive to bright treble will likely find it comfortable for hours at a time.

If your reference points are clarity, air, and a forward top end, this is not the speaker for you, because those qualities are simply not its priority. Buy it for a warm, large presentation, pair it with amplification that can drive a 4 ohm load, and it is an easy recommendation.

Conclusion

The Monolith by Monoprice Encore B6 is a warm, bass-rich bookshelf speaker whose imaging stands out clearly in its price range. Its midrange and treble are relaxed rather than revealing, which is a trade-off rather than a defect, and it suits listeners who want to feel their music as much as hear it.
