Bookshelf Speakers - Castle Audio
Bookshelf speakers, or standmount speakers, are an excellent alternative to floorstanding speakers for smaller rooms or those wanting something smaller. In many cases, they are an excellent choice for accurate sound and many studios use bookshelf sized speakers for monitoring.
We prefer to call them "stand mount" rather than "bookshelf" as they generally sound better on dedicated speaker stands which prevent a "boomy" sound in smaller spaces. You can control bass response by choice of stands. All speakers here are passive and require a suitable hi-fi amplifier. While we usually recommend this type of system (hi-fi separates and passive speakers) for the very best sound quality, we also sell excellent wireless and active speakers. Prices include free mainland UK delivery and full 30 day money back guarantee if you change your mind, so buy with confidence.
Castle Audio speakers are made in Yorkshire and the company is named after the famous Skipton castle. They are based in the town of Skipton and are rare in that they also make their own drive units and all manufacturing is still done locally. The brand has been relaunced with the beautiful Winsdor loudspeakers.
Castle also makes the air core inductors used in the crossovers. Not to mention the beautiful wood-veneered cabinets. In fact, they are renowned as a complete loudspeaker manufacturer. Despite globalisation, they still manufacture in the UK.
Drive units
The drive units used by Castle Audio are designed and developed in-house and their build quality is the key to the Castle sound. They often feature the most recent technologies while maintaining a traditional feel. Most of the bass units feature cones made from woven carbon fibre. This is light yet exceptionally stiff.
They also use woven polypropylene in the Windsor range. The voice coil formers have a high power handling capability as well as innovative magnet assemblies. As a result, a more linear motion is maintained. This is designed to improve dynamics and reduce distortion.
Additionally, lightweight materials reduce the mass of the cones resulting in a faster response with modern musical sources.
Flat response Tweeters
The Castle Audio tweeters are designed to be a good match to the bass units. They have a very flat response due to the fact that they use no ferrofluid for cooling. The crossovers also use the best possible quality components.
Quality cabinets
An important part of any speaker is the cabinet, and the in-house experience of Castle Audio is used to design the cabinets and drivers in tandem. This allows all of the interactions to be modelled and tweaked to give the best results. Finally, experienced staff choose the best quality veneers for the cabinets.
Traditionally, floorstanding loudspeakers are considered the ultimate to Hi-Fi with bookshelf speakers being largely perceived as too lightweight or compact to compete with their larger counterparts. However, the past 20 years has seen a drastic improvement in manufacturing and miniaturisation techniques so these standmount speakers can compete with floorstanders adding their own advantages as well.
Bookshelf speakers typically have more attack and rhythm than floorstanding models so they are more suited to complex tracks and rhythmic music. This is often viewed as a compromise between the weight and dynamics of a floorstanding speaker and the musicality possible with a bookshelf speaker.
Driver design and material is crucial when selecting a bookshelf speaker. There are various driver materials from Kevlar to paper – the top distinction being metallic or non-metallic drivers. A metal driver, typically aluminium, benefits from accuracy and precision. However, some listeners may describe this as "bright" or "analytical". Non-metallic drivers generally feature more engaging musicality and warmth at the expense of the absolute precision of a metal driver.
Tweeter design also hugely impacts the sound signature. Typically, entry-level and mid-range models incorporate a dome-shaped tweeter while higher-end speakers use a ribbon tweeter incorporating a diaphragm of stretched metallic ribbon. This delivers more lucid and broadly-dispersed highs, for better imaging and soundstage.
Most configurations employ a main bass/mid frequency driver paired with a separate tweeter handling high frequencies. However, some manufacturers choose to house the tweeter in the centre of the main driver to improve dispersion and imaging and make positioning easier and more versatile.
Dedicated speaker stand are ideal to position bookshelf speakers at the optimal listening height with the tweeters at ear level from the usual seating position. This achieves best imaging and ensures coherency and integration between the woofer and tweeter. They also add weight and authority to enhance bass extension. Many stands are fillable, letting you add weight and mass to further tweak the bass performance of your speakers. Base spikes ensure isolation from the floor and stop unwanted resonance from degrading the sound of your speakers.
