Choosing between high-end floor-standing speakers can be a daunting task, especially when faced with two compelling contenders like the KEF Q11 Meta and the Polk Reserve R700. Both retail around $2,100 and offer impressive three-way designs, but their distinct driver configurations and construction lead to noticeably different sonic characteristics. This in-depth comparison delves into the nuances of each speaker, examining their frequency response, soundstage, and room integration capabilities to help you determine which model best suits your listening environment and preferences.This review analyzes key performance aspects, including bass extension, tonal balance, dispersion patterns, and crossover implementation. We'll explore how each speaker behaves in various room setups, highlighting the impact of proximity to walls and side reflections on the overall listening experience. Ultimately, we aim to provide a clear understanding of the strengths and weaknesses of both the KEF Q11 Meta and the Polk Reserve R700, empowering you to make an informed decision based on your individual needs and priorities.
Pros And Cons
- Maintains consistent sound profile regardless of listening position (within ±50° horizontally).
- Works better in typical rooms with nearby sidewalls.
- Benefits from being placed closer to the wall, enhancing low-frequency envelopment.
- More linear response in seated position due to sidewall reflections.
- Bass rolls off quickly when moved away from the wall.
- Digs lower in frequency (5-10 Hz lower than KEF).
- Wider radiation through the mid-range, creating a larger soundstage.
- More linear on-axis response.
- Sounds brighter than KEF.
- High-frequency radiation narrows quickly above 7kHz.
- High treble rolls off quickly if not sitting directly in front of the tweeter.
- Bass can be boomy if placed too close to the wall.
- Sounds bright in rooms with nearby sidewalls due to off-axis behavior and reflections.

Speaker Specifications and Initial Impressions
Both the KEF Q11 Meta and the Polk Reserve R700 are high-end floor-standing speakers retailing around $2,100. While both utilize a three-way design, their driver configurations differ significantly. The Polk boasts dual 8-inch woofers, a 6.5-inch midrange, and a 1-inch tweeter, whereas the KEF features a coaxial driver incorporating a 3/4-inch tweeter and 4-inch midrange, supplemented by three 6.5-inch mid-bass drivers. The Polk is considerably heavier, suggesting a more robust build.
Despite their comparable dimensions, the difference in weight points to distinct construction and likely sound characteristics. The initial sound comparison hints at the Polk producing a slightly brighter, more expansive soundscape, while the KEF offers a potentially more refined and detailed listening experience. This initial observation underscores the need for a deeper dive into the nuances of each speaker.
Sound Quality and Listening Experience
Assuming optimal room setup for both speakers, the Polk Reserve R700 extends slightly lower in the bass frequencies (approximately 5-10Hz), delivering a more impactful low-end experience. However, its slightly brighter tonal balance might be perceived as less natural by some listeners. The wider horizontal dispersion of the Polk creates a larger, more enveloping soundstage.
Conversely, the KEF Q11 Meta maintains a consistent sound profile over a wider listening area due to its narrower horizontal dispersion, making it ideal for multiple listeners or home theater setups. While the Polk's wider dispersion offers a more expansive soundscape, its high-frequency response narrows significantly above 7kHz, potentially affecting treble clarity for off-axis listeners.
Room Placement and its Impact
Room acoustics significantly influence the performance of both speakers. The KEF Q11 Meta thrives in typical rooms with nearby sidewalls, effectively utilizing reflections for a linear sound. Its design prioritizes performance in smaller spaces, with the ability to be placed closer to walls without sacrificing bass response.
The Polk Reserve R700, on the other hand, benefits from being positioned further away from walls to mitigate excessive bass boominess. Its wide dispersion can cause brightness and sibilance issues in rooms with close sidewalls. Therefore, room characteristics dictate which speaker will ultimately perform better.
Detailed Analysis: Spinorama Data and Frequency Response
Analyzing the spinorama data reveals the KEF Q11 Meta's linear on-axis and listening window response, though with a slight dip around 2-3kHz. The Polk Reserve R700 exhibits a more linear on-axis response but features a significant discontinuity in the 3-7kHz range, impacting the crossover quality. This suggests that the KEF's crossover implementation is superior, mitigating potential tonal imbalances.
Furthermore, the KEF Q11 Meta shows a declining sensitivity across frequency ranges, particularly noticeable in the treble. Conversely, the Polk Reserve R700 demonstrates a more neutral on-axis and listening window response. These findings highlight the need to consider individual room characteristics when comparing these speakers.
Conclusion and Recommendation
The KEF Q11 Meta and Polk Reserve R700 offer distinct sonic profiles and room integration characteristics. The KEF excels in smaller, more typical rooms with nearby sidewalls, offering a balanced, detailed soundstage. Its design optimizes for closeness to walls, maximizing bass response.
The Polk Reserve R700, better suited for larger rooms and those without close sidewalls, provides a broader, more immersive soundscape but needs careful placement to avoid excessive bass boominess and brightness. The ultimate choice hinges heavily on the listener's room setup and preferences for tonal balance. Both are excellent speakers, but neither is definitively superior without considering the context of their intended usage.
