When it comes to bookshelf speakers, the choice between premium and value options often comes down to understanding what really matters for your specific needs. Today we're comparing two popular but differently positioned options: the $550 Bowers & Wilkins 606 S3 and the $279 Polk Audio Signature Elite ES20.
Bookshelf speakers remain one of the most versatile and popular choices for both music and home theater. Despite their name, they're often placed on dedicated stands to achieve optimal sound. These compact performers can deliver impressive audio quality when properly positioned and powered.
The main considerations when choosing bookshelf speakers include:
The B&W 606 S3 represents the latest evolution of B&W's acclaimed 600 series, featuring their premium Continuum cone technology that was previously only found in their more expensive lines. This material, which replaced their long-used Kevlar, provides exceptionally clear midrange reproduction - think vocals and acoustic instruments - with minimal distortion. The new Titanium dome tweeter represents a significant upgrade, delivering crisp high frequencies without becoming harsh.
In contrast, the Polk ES20 takes a more traditional approach with its Dynamic Balance driver technology. While perhaps not as exotic as B&W's solutions, Polk's implementation delivers impressive performance for the price point. The Terylene dome tweeter handles high frequencies competently, though with slightly less refinement than the B&W's titanium unit.
Both speakers utilize 6.5-inch woofers, but their approaches to bass reproduction differ notably. The B&W employs a rear-firing port design that can deliver tight, controlled bass but requires more careful placement away from walls. The Polk uses their proprietary PowerPort technology, which helps reduce port noise and can actually provide slightly deeper bass extension despite the lower price point.
Power handling is robust on both models:
Let's break down some key specs and what they mean for real-world use:
Sensitivity
This 2dB difference means the B&W will play slightly louder with the same power input, though the difference is minimal in practice.
Frequency Response
While both speakers boast impressive frequency ranges, the Polk actually extends lower in bass, which might surprise some given the price difference. However, the B&W typically offers better control and detail in its bass reproduction.
The 606 S3 excels with acoustic music, jazz, and classical recordings where its superior imaging and detail retrieval become most apparent. The speaker creates a precise soundstage where you can clearly place each instrument in space. Its midrange clarity is particularly impressive with vocals and acoustic instruments.
The Polk ES20 offers a slightly warmer presentation that some listeners might actually prefer, especially with modern pop and rock music. While it may not match the B&W's ultimate resolution, it provides an engaging listening experience that's notably good for its price point.
Both speakers work well in home theater applications, though they shine in different ways:

Both speakers represent excellent choices within their respective price points. The B&W 606 S3 offers superior refinement and detail, particularly in the midrange and treble, while the Polk ES20 provides remarkable value and surprisingly capable performance across the board.
For pure two-channel music listening where every detail matters, the B&W makes a compelling case for its higher price tag. However, the Polk ES20 might actually be the more practical choice for many users, especially those building a home theater system or wanting very good performance without breaking the bank.
Remember that proper positioning and amplification will be crucial to getting the best performance from either speaker. Take time to set them up correctly, and they'll reward you with years of enjoyable listening.
