SUPRA Classic 2×2.5 mm² – Tin-Plated OFC Speaker Cable, Made in Sweden
SUPRA Classic 2×2.5 mm² is a high-quality speaker cable developed and manufactured in Sweden for HiFi, home cinema and professional audio installations. The cable uses tin-plated 5N OFC conductors (>99.999% pure copper), providing low resistance, high flexibility and a long service life even in demanding environments.
The tin plating contributes to corrosion resistance and reduced skin effect, while the PVC insulation is selected for its chemical stability. The result is a cable that retains its electrical properties over time and is equally suitable for a home stereo system or a larger audio installation.
Benefits
- Tin-plated 5N OFC conductors (>99.999% pure copper) for low resistance
- Chemically stable PVC insulation
- Multi-stranded, flexible construction that is easy to route through cable trunking and furniture
- Printed polarity marking and metre marking for easier installation
- Developed and manufactured in Sweden
Tin-plated 5N OFC copper
The SUPRA Classic range uses multi-stranded conductors made from 5N oxygen-free copper with a purity above 99.999%. The conductors are tin-plated to resist oxidation and help maintain stable electrical contact over many years of use. The tin plating also acts as a barrier between the strands, reducing skin effect and contributing to even signal transmission at higher frequencies.
High flexibility for easy installation
The fine-stranded conductor construction makes the cable highly flexible and easy to route through cable trunking, furniture, equipment cabinets and installation conduit. The cable is therefore equally suitable for new installations and upgrades to existing audio systems.
Good to know
The PVC insulation is selected for chemical stability and long-term durability. For outdoor installation, SUPRA recommends routing the cable inside protective conduit for the best service life.
Ideal for
- Stereo systems and home cinema
- Ceiling and in-wall speakers, installation speakers
- Multiroom systems such as Sonos Amp and Bluesound Powernode
- PA and audio installations with low-impedance loudspeakers
- 70 V installations where the cable's rated voltage meets the installation requirements

PC & HiFi Örebro recommends
SUPRA Classic 2×2.5 mm² is a dependable choice for most home and home-cinema installations with normal cable lengths. For very long cable runs or low-impedance speaker loads, a larger conductor cross-section from the same range can provide lower voltage drop and should be considered instead.
