Bookshelf Speakers: High-End Passive vs. Budget Powered - A Detailed Comparison

The world of bookshelf speakers is fascinating, with options ranging from affordable powered units to premium audiophile-grade components. Today, we're comparing two very different approaches: the high-end Bowers & Wilkins 707 S2 ($959) passive speakers and the budget-friendly Edifier R1280DBs ($160).

Understanding the Landscape

Bookshelf speakers, despite their name, are versatile audio components that work well on stands, desks, or yes, actual bookshelves. The key distinction in our comparison is between passive speakers (requiring an external amplifier) and powered speakers (with built-in amplification).

The B&W 707 S2 represents the audiophile approach, part of B&W's renowned 700 Series that brings technology from their flagship 800 Series to a more attainable price point. Released in 2018, these speakers showcase several innovative technologies that we'll explore.

The Edifier R1280DBs, introduced in 2020, takes a more practical approach, integrating modern connectivity with proven speaker design. It's an evolution of Edifier's popular R1280 series, adding Bluetooth 5.0 and improved digital processing.

Sound Quality Deep Dive

High Frequency Performance

The B&W 707 S2's Carbon Dome tweeter, which pushes its frequency response up to 28kHz, represents a significant engineering achievement. The carbon coating creates a stiffer, more responsive dome that reduces distortion in the critical high frequencies. This translates to more precise cymbal strikes, airier vocal harmonics, and better reproduction of acoustic space.

The Edifier's 13mm silk dome tweeter, while competent, can't match this level of sophistication. Its frequency response extends to 20kHz - the theoretical limit of human hearing - but lacks the refinement and "air" of the B&W design.

Midrange Reproduction

Here's where the B&W's Continuum cone technology really shines. This proprietary material, developed over eight years, provides exceptionally clean and detailed midrange reproduction. Voices sound more natural, with better separation from accompanying instruments. The controlled break-up behavior of the cone (how it handles frequencies at its physical limits) means less distortion and more accurate sound.

The Edifier uses a more traditional cone material that, while perfectly adequate for casual listening, doesn't achieve the same level of clarity and precision. However, its built-in DSP (Digital Signal Processing) helps maintain balanced sound at different volume levels.

Bass Response

Despite their compact size, the B&W 707 S2's manage impressive bass extension thanks to their Flowport technology - essentially a carefully engineered bass port that reduces turbulence and unwanted resonance. The result is cleaner, more defined bass that reaches down to 50Hz without the "chuffing" noise common in lesser designs.

The Edifier's bass response is more limited, though still respectable for the price. Its 4-inch woofer and simpler port design mean bass drops off more quickly below 55Hz. However, the inclusion of a subwoofer output allows for easy system expansion if deeper bass is desired.

Practical Considerations

System Requirements

The B&W 707 S2 requires careful amplifier matching - they're relatively inefficient at 84dB sensitivity and need 30-100 watts of clean power. This means budgeting at least $500 for a quality amplifier, plus speaker cables and source components. However, this separation of components allows for future upgrades and system optimization.

The Edifier R1280DBs eliminates these considerations with its built-in 42-watt amplification. While this limits ultimate performance potential, it greatly simplifies setup and ensures all components are properly matched.

Connectivity and Flexibility

Here's where the Edifier shows its modern sensibilities. Bluetooth 5.0 support, optical input, and multiple analog inputs make it supremely versatile. You can easily switch between a TV, computer, phone, and other sources without any additional equipment.

The B&W speakers, being passive, require external electronics to handle input switching and volume control. However, their superior technical capabilities make them more suitable for critical listening and high-end home theater applications when properly amplified.

Value and Long-Term Considerations

The price difference between these speakers is substantial, but it's important to consider the total system cost and intended use. The B&Ws represent an investment in long-term musical enjoyment, with performance potential that grows with system upgrades. Their construction quality and manufacturer support suggest a decades-long service life.

The Edifiers offer remarkable value for their price, especially considering their built-in amplification and connectivity options. While they won't match the absolute performance of the B&Ws, they provide a complete, immediate solution that works well for many users.

Home Theater Applications

In a home theater context, the B&W 707 S2s excel when matched with appropriate electronics. Their precise imaging and dynamic capabilities make them excellent front channel speakers, though you'll want to match them with other speakers from the 700 Series for best results.

The Edifiers can serve in a simple home theater setup, particularly with their optical input, but lack the refinement and output capabilities for serious home theater use. They're better suited to near-field listening or small room applications.

How to Decide

Choose the B&W 707 S2 if:

• Sound quality is your primary concern
• You're willing to invest in quality amplification
• You appreciate the ability to upgrade system components
• Critical listening or serious home theater use is planned

Choose the Edifier R1280DBs if:

• Budget is a major consideration
• You want simple setup and operation
• Multiple input options are important
• Near-field listening (desktop/computer use) is primary

Both speakers represent excellent values in their respective categories, but they serve very different needs. The B&W 707 S2 is for the discerning listener seeking premium sound quality, while the Edifier R1280DBs offers a practical, budget-friendly solution for everyday listening.
