SoundStage!'s original review captured the shift it represented well: where subwoofers had long been seen by two-channel purists as a home-theater compromise, the B15 was built specifically to change that perception, with a level of engineering and control aimed squarely at music listeners. ## Build & Design The Revel Performa B15 is a sealed-box design housed in a substantial 1-inch-thick MDF cabinet, weighing around 105 lbs — evidence of just how over-built the enclosure is relative to typical consumer subs. At its heart is a 15-inch driver combining a Kevlar-pulp-and-alloy composite cone, a massive 130oz magnet assembly, and a 4-layer voice coil with a full 3 inches of peak-to-peak excursion, mounted on a rigid cast aluminum frame. That's a driver built for both output and control, not just outright size. It's powered by a 1000W RMS class AB amplifier — a deliberate choice by Revel's engineers, favoring the sound quality of a traditional analog amp topology over the higher on-paper wattage numbers class D digital amps were starting to advertise at the time. ## Performance Measured frequency response runs from 20-80Hz (±0.5dB), with output extending down to an impressively low -3dB point at 18Hz for a sealed design. Independent lab measurements found the B15 could reach just under 100dB before running into distortion on demanding, deep-bass test material, with only minor idiosyncrasies showing up in dynamic-range behavior at very high output levels around 30Hz — a strong result overall. In listening, reviewers consistently single out the B15's combination of authority and finesse. One home-theater-focused review described its musicality as something the "small" subwoofer category simply doesn't offer, while SoundStage!'s original assessment held the B15 up as a benchmark for how a subwoofer could support fine two-channel music systems without smearing detail or overwhelming the rest of the system. It's a sub built to disappear into the presentation rather than call attention to itself with one-note boom. ## Features Where the The Revel Performa B15 really distinguishes itself is setup flexibility. It includes a 3-band parametric equalizer along with switchable/defeatable high-pass and low-pass filters (30-80Hz, with multiple slope options), continuously variable phase from 0-180°, and both balanced XLR and unbalanced RCA inputs and outputs — including pass-through outputs for looping a second B15 into the system. Revel's PC-based room correction software (bundled with certain configurations) lets owners measure and fine-tune in-room response with an SPL meter, a level of setup sophistication well beyond typical plug-and-play subs of its era. ## Value Originally priced around $2,995 (with a $300 upcharge for premium natural cherry or maple finishes over the standard black ash), the B15 sold as a genuine high-end component rather than a budget add-on. On the used market today, well-kept examples can be found for a fraction of that original price, and long-time owners and reviewers alike consider it to have held its value remarkably well for a two-decade-old design — user reviews on audioreview.com average a rare 4.8 out of 5. ## Verdict **Pros:** Exceptionally rigid, over-built cabinet and driver; deep, well-controlled bass with genuine musicality; extensive tuning flexibility via parametric EQ, phase, and crossover controls; strong measured performance even at high output; excellent reputation and resale value. **Cons:** Large and very heavy at 105 lbs; sealed-box design trades some ultimate output/efficiency for control, so it doesn't chase the loudest headline SPL numbers; original price was steep, and setup rewards a bit of patience to dial in the EQ and phase controls properly. **Bottom line:** The Performa B15 remains one of the more respected "audiophile subwoofer" designs of its generation — built to integrate with serious two-channel systems rather than just add home-theater slam, and still capable of holding its own against much newer competition. The Revel Performa B15 (and updated B15a) is a highly regarded, audiophile-grade powered subwoofer known for its deep musicality and extensive customizability. Featuring a massive 15-inch Kevlar-pulp-and-alloy driver and 1000W RMS Class-AB amplifier, it delivers a frequency response down to –3dB at 18Hz.
