| Content | The true all-rounder, the Wharfedale DIAMOND 12.1 is a traditional standmount (or bookshelf) speaker that embodies the history and performance values of the Wharfedale DIAMOND series.
The perfect ‘affordable’ hi-fi speaker, the DIAMOND 12.1 offers the best of both worlds – compact size with power and detail.
Perfect for 2-channel hi-fi systems, thanks to its intricate performance but also compact and capable for immersive home theatre, the DIAMOND 12.1 is designed and certified to perform, regardless of room size and application.
The DIAMOND 12.1 features a high-performance 130mm (5”) KlarityTM driver for exceptional timing and refined bass. The superb 25mm (1”) woven polyester dome tweeter delivers open and smoothly extended high frequencies.
A voice coil beyond this class
The voice coil is wound on a high-power epoxy/glass fibre bobbin highly unusual in speakers at this price level. This has the advantage of not adding eddy currents and delivering greater power handling than an aluminium bobbin, whilst also being much stiffer than the Kapton type associated with this price-class.
DIAMOND highs
The 25mm dome is made from a woven polyester film with a high-loss coating to deliver open and smoothly extended high frequencies. The magnet system and the front plate have been optimised for wide dispersion and uncompressed behaviour. The front plate is flat and exposes the dome as much as possible; only a very short duct on the front plate balances the acoustic load and improves the SPL (sound pressure level) measurement.
A crossover of style
The crossover network uses an acoustic LKR 24dB topology. This includes air-core inductors of the type more commonly found in high-end speakers, selected because they produce the lowest distortion of all inductor types. As the resistance of the coil is higher than a standard laminated steel or ferrite core inductor, the magnetic structure of the mid/bass driver has been modified to compensate, resulting in fast, clean bass with no distortion from the inductor.
Firm and fair
The DIAMOND 12.1 ’s rear-ported enclosure is precisely sized so that the internal volume works in harmony with the drive unit system to deliver the desired sonic result. A multi-layered sandwich design subdues the identifiable characteristics of the cabinet’s ‘sound’. Even the resonant properties of the glue between the layers was measured to determine the optimum combination.
Brace yourself
Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific form of the wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace ‘figure of eight’ brace, which may simply transfer resonance from one wall to another.

High Performance, Compact Size, Surprising Price
Don't settle for flat sound from your flat panel TV, and don't miss out on the excitement of digital surround-sound in your shows, movies and games. Great surround-sound doesn't have to take up a lot of space or cost all that much. The payback is family fun and entertainment excitement. Don't miss out.
TL1 Features:
- The silk dome tweeter delivers a classic, clear, detailed Polk performance, with pinpoint imaging and smooth highs that are never tiring.
- Time Lens® technology aligns the acoustic centers of the tweeter and mid-bass driver on the same spatial plane for superior imaging, while an acoustic lens incorporated in the grille smoothes the tweeter's frequency response.
- The unique curved enclosure design employs non-parallel surfaces to strengthen the acoustically inert enclosure and deliver less audible coloration from internal surface resonances.
- Because of its Extended Linear Motion motor structure, the moving parts of the drivers used in the Blackstone TL Series can move farther, more smoothly, in a smaller space than any other speaker driver in an enclosure this size, achieving the kind of dynamic response (clarity, volume) you'd expect from much larger speakers.
- An aperiodic-tuned rear-firing bass port combines the extension of a ported enclosure with the smoother low-end of an acoustic suspension enclosure, controlling port air flow for the kind of big bass response, and perfect speaker-subwoofer blending, you'd never expect from a loudspeaker you can hold in the palm of your hand.
- The Blackstone aerated polypropylene cone is lightweight, but stiff and strong, with longer linear excursion capabilities in a limited compact enclosure space, so it plays louder with less distortion.
- A super-small long-throw mid-bass driver, tuned with our patented Dynamic Balance® technology, delivers astonishingly smooth, flat frequency response, superior transparency and detail, and the surprising ability to play really, really loud for such a small speaker.
- Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
- Hi-Gloss "Blackstone" finish, a durable, deep automotive-strength finish that matches today's most stylish flat-panel TVs and furniture.
- Compact means go-anywhere for Blackstone TL: on shelves, on the wall, on stands. Built-in keyhole slots and threaded inserts (that fit virtually any brackets) give you multiple mounting options.
- Gold-plated, professional-style 5-way binding posts, for the most secure connection options.
- All models in the Blackstone TL Series are available in convenient, professionally matched 5-packs for instant home theater solutions in any room. There are two complete systems available that include a subwoofer; everything you need for an explosive, compact, easy-to-connect home theater system. Plus, you can use individually-available satellites to expand your systems to accommodate 6.1, 7.1 and beyond.
