Synergistic Research Foundation XL IFT Jumpers (Set of 4)

Synergistic Research Foundation XL IFT Jumpers

Foundation XL IFT Jumpers use Synergistic Research's Integrated Frequency Termination (IFT) technology to bi-wire speakers without the phase distortion that comes from splitting a signal across two separate cable runs. Built using Foundation XL speaker cable geometry, they carry the full spectrum of frequency and phase information through a single cable rather than segregating high and low frequencies into separate paths, so your amplifier sees a consistent load from top to bottom. This delivers more accurate soundstaging, pace, and high-frequency extension than traditional shotgun bi-wire or generic jumper/binding-strap connections. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you determine whether IFT Jumpers or a fully bi-wired cable pair is the right fit for your speakers.

Key Features

• Integrated Frequency Termination (IFT) design, avoids the phase distortion inherent to split-frequency bi-wiring
• Built on Foundation XL speaker cable geometry for tonal consistency with a matching Foundation XL speaker cable run
• Keeps full-spectrum phase information intact, rather than dividing it across separate high/low-frequency paths
• Higher-quality alternative to generic jumper cables or bi-wire binding straps

Why IFT Instead of Standard Bi-Wiring?

Traditional bi-wiring feeds a speaker's high-pass and low-pass filters with different input signals, since high and low frequencies travel through separate cable runs that see different loads. This creates phase error between the drivers, which typically shows up as a loss of soundstage precision and recordings that start to sound alike. "Shotgun" bi-wiring, using two parallel speaker cables terminated to a common set of connectors, doubles cost without solving this problem, since the amplifier still sees mismatched loads across frequencies. Generic jumper cables and binding straps compound the issue further, since they're rarely tuned to the frequency range they carry and add extra connector hardware that degrades the signal. IFT Jumpers avoid all of this by keeping the full frequency and phase spectrum in one continuous cable geometry.

Frequently Asked Questions

Do I need a bi-wire speaker or a single-wire speaker for IFT Jumpers?
IFT Jumpers are designed to bridge a bi-wire speaker's high and low frequency binding posts when you're running a single (non-bi-wire) speaker cable pair, giving you IFT's phase-correct performance without the cost of a fully bi-wired cable set.

Is IFT Jumper performance the same as a fully bi-wired IFT speaker cable?
Very close. The only difference is the addition of one extra set of connector hardware (spade or banana) at the jumper connection point.
