To celebrate the twentieth anniversary of the Q4 hifi rack we developed the Bronze upgrade that can be easily retro fitted to any Q4 or SVT HiFi rack or wall shelf. Bronze has a broader tonal spectrum and greater sustain that opens the soundstage of your system making it more musical and enjoyable without losing detail.
The main design features of the Bronze upgrade spike assembly are the SVT curve design of the top bolt and the rounded spikes that together encourage any residual mechanical resonance to flow and dissipate more easily.
- Improved performance for source components
- Beautiful bronze engineering
- Adjustable spiked assembly for finer levelling
Central to all our research was extensive listening tests using the tried and tested technique of tuning by ear in the same way as the finest musical instruments are developed. In fact Bronze is one of several high copper content alloys used as a substitute for the more common types of brass to construct the bodies and bells of metal wind instruments. Even some instrument strings for acoustic guitars, mandolins and violins are wrapped with bronze. In addition to the distinctive appearance provided by the reddish-orange hue of bronze, it provides a broader harmonic response spectrum.
Select Q4 for the Bronze Upgrade Kit (4-spikes) suitable to Q4 Large/Q4 EVO models.
Quadraspire at a glance
Welcome to Quadraspire, the contemporary furniture manufacturer based in Bath, England. Since 1995, we have been designing & manufacturing Hi-Fi furniture blending functionality & style with acoustic performance.
Quadraspire produces an extensive range of modular performance Hifi Stands and TV Stands, in both wood and glass, to enhance your sound system both sonically and visually.
Quadraspire launched its first product, the modular Q4 Hi-Fi table in 1995. Our ever evolving range has been critically acclaimed not only for its style and function but for its acoustic performance, in particular the new Q4 reference table.
Quadraspire audio furniture really will make your audio systems sound better, and not just a little - but a lot better! Here is a typical reviewer’s comment:
"The Q4 provided a very neutral sound. Unlike many supports, the Q4 seemed to emphasize no part of the frequency spectrum unduly. Bass was full-blooded and articulate, the midrange clear and balanced, while treble information was projected cleanly in an orderly fashion."
Best Buy, Hi-Fi Choice.
Quadraspire uses toughened glass and real wood veneers that are unique in beauty and therefore individual in grain and colour. The Quadraspire design approach is an innovative fusion of function and performance in a distinctive style. With its stylish, contemporary design and choice of rich real wood veneers, Quadraspire equipment racks are truly beautiful furniture which actually enhance the look of any nice room. Chamfered shelves make the stands look smaller and lighter than they really are. Moreover, Quadraspire equipment looks much better in the flesh than in the photos. But don’t to take our word for it. Contact your dealer. 
One of the beauties of Quadraspire designs is that you can add shelves to an existing rack as your system expands, as is the the case with the best selling Quadraspire Q4 Evo. Assembly is extremely fast and easy, a rack can be assembled in ten minutes! Because of the modular design you can order an additional shelf, with any height column, at any time.
In addition Quadraspire also produces a line of modular cabinets Hifi, CD & LP storage.
