About This Item
Description
The Siren is designed to create the kind of first-listen realization that a spec sheet alone cannot convey — a speaker cable that lets your amp and cabinet speak without the strand-interaction haze of ordinary wire. This listing is the 5 ft (1.5 m) version with straight 1/4" phone plugs on both ends.
Choose the right version
This is the 5 ft (1.5 m) straight-to-straight version with 1/4" phone plugs (model SI2SS5). Choose the length that matches the distance between your amplifier head and cabinet. The Siren is also built in 3 ft and 10 ft lengths and with Speakon connectors.
Why players choose the Siren
Players choose the Siren to handle the demands of a speaker-level signal cleanly. Six individually insulated 20 AWG IGL conductors — three positive and three negative — run in a helical, open-core twisted-pair array so the cable can carry current without the strand interaction that colors ordinary speaker cable.
The Siren is a speaker cable for amp-to-cabinet use only — it is not a line-level or instrument cable.
Key features
- Six individually insulated 20 AWG solid-core IGL copper conductors (three positive, three negative)
- Helical, open-core twisted-pair geometry with spacing between poles to reduce magnetic interaction
- Polypropylene insulation holds the conductors rigid; durable PVC outer jacket
- Neutrik phone plugs with high-copper-content brass contacts, nickel plating and a chuck system that keeps the cable mechanically attached
- Soldered with TRT Wonder Solder Signature; directional (red boot toward the cabinet)
- Hand-built in the USA from USA-manufactured material

FAQ
Why does the Siren use six conductors? A single 20 AWG conductor doesn't provide enough cross-section for an amplified speaker signal, so three positive and three negative conductors run helically for lower resistance and better damping between amp and speakers.
Which end goes where? The cable is directional and each run is tested: connect the end with the red boot to the speaker cabinet and the other end to the amplifier's speaker output.
Can I use it as a guitar or patch cable? No. The Siren is built for the speaker-level connection between an amplifier and a cabinet; use an instrument cable between guitar, pedals and amp.
Is a Speakon version available? Yes, the Siren is also made with Speakon connectors; this listing is the 1/4" phone-plug version with straight plugs on both ends.
What lengths are available? The standard Siren comes in 3 ft, 5 ft and 10 ft lengths; this listing is the 5 ft cable.
