Let’s talk about cables, not just any cable, but the one specifically designed to bring out everything your REL is capable of. Bassline Blue may look like a cable, but don’t be fooled. This is a purpose-built performance component, engineered with the same obsessive precision we pour into our subwoofers. It's not an afterthought, it's the final piece of the puzzle.
What Is Bassline Blue and Why Should You Care?
When you’re after reference-quality bass, every detail counts. And few details hold more significance than the path between your amplifier and your subwoofer.
Bassline Blue was developed specifically for REL’s high-level connection, which pulls its signal directly from your amplifier’s speaker terminals, the same signal your main speakers hear. This approach allows your REL to speak the same language as the rest of your system matching tone, timing, and texture with effortless precision.
Available in 3M, 6M, and 10M lengths, it offers flexibility without sonic sacrifice. It’s tuned to perform whether you’re in a compact listening room or a sprawling home theater.
What Makes It Special? A Filter Board, Hidden in Plain Sight
Inside each Bassline Blue lies the secret sauce: a proprietary filter board, hand-designed by REL engineers and tailored specifically to our subwoofers. This isn’t just fancy wiring; it’s genuine engineering.
Here’s what that circuit does:
- Protects signal purity
- Matches impedance properly
- Delivers tighter, more defined bass
No off-the-shelf cable can do this because they’re not made for REL. This is. Think of it as a tuned exhaust system for your subwoofer, built not just to connect, but to elevate.
It’s Not Just About Bass, It’s About the Whole Picture
Sure, Bassline Blue tightens up the low end. But the magic is what it does across the entire soundstage. We call it the “illumination effect”—that moment when suddenly, everything becomes clearer. Vocals lift. Instruments separate. The space around the music opens.
You’ll hear:
- More nuance
- Deeper integration
-
A sense that your sub isn’t just “adding bass,” but expanding the entire experience
Your REL doesn’t call attention to itself, it simply vanishes into the system and lets the music take over.
For Owners of Audio Research, D’Agostino & CH Precision: A Special Edition, Engineered for You
Audio Research, D’Agostino, and CH Precision amps are legendary, no question, but their output impedance is anything but conventional. That distinctive design, while part of what makes them great, can challenge traditional cables. So, we did what we always do: got to work. By collaborating directly with these manufacturers, we developed a dedicated Bassline Blue Special Edition, purpose-built to handle their unique demands. It’s the only cable we officially recommend for these top-tier amps tuned to extract every ounce of performance, without compromise.
What you get:
- A custom impedance-matched filter circuit
- Stackable banana plugs for clean, easy connections
- Available in 3M, 6M, and 10M lengths
The result? Proper integration, proper safety, and the kind of musicality that makes you stop what you’re doing and listen.
Design That Lasts, Built Like a REL
Every element of Bassline Blue reflects the same design philosophy we bring to our subs:
- High-grade materials chosen for durability and fidelity
- Low resistance for pure signal flow
- Elegant proportions that quietly complement any system
It’s handsome, yes—but more importantly, it’s honest. It’s built to serve the music, day in and day out.
Why Upgrade? Because It’s the Missing Link
If you’re using our high-level connection and we hope you are then cable quality is imperative. Timing, transients, coherence, and musical flow are all shaped by what runs between your amp and your REL.
Bassline Blue isn’t just a nice-to-have. It’s the finishing touch.
Whether you’re building your first reference system or tuning an already-great rig, the difference is real. And once you hear it, you won’t go back.
Final Word from John
Bassline Blue was never intended to be just another cable. It’s a REL system component, purpose-built to unlock the full potential of your subwoofer and, frankly, your whole system.
From high-end NAIM setups to modern integrated amps, if your REL deserves the best, this is it. Don’t just connect your REL. Complete it. Bassline Blue. Experience the difference.
