Ronbus Quanta First Impressions
Ronbus dropped the Quanta out of nowhere. A full-foam-core lineup priced at $120 ($100 with a discount code PBSTUDIO).
After two sessions, it honestly makes Ronbus’s recent lineup confusing, because this feels like what the Ripple wanted to be… at a fraction of the price.
So far, this paddle clears all of the Ronbus’s other lineups and doesn’t feel there is a reason to recommend any of their other paddles.

Price and Release
Retail: $120

Pre-orders open on Friday, September 5, with the official release on September 12.
At this price, the Quanta undercuts most foam-core power paddles while offering a full family of shapes.
The Five Shapes
Ronbus is launching five shapes.
The quick read: R1 and R3 are elongated (aero vs square), R2 and R5 are widebodies (R5 adds handle length), and R4 is the hybrid.
My take on shapes: For most people, I’d recommend the R2 widebody. It’s easy to swing and plenty versatile. If you rely on a two-handed backhand and need extra handle length, the R5 is the better fit. Otherwise, just go with the shape you’re already comfortable using.

How It Plays - How to Unlock the Paddle
Out of the box: very light swing weights across the board (101–111). That’s the polar opposite of the heavier Ripple family. Quick in the hand, easy to maneuver, but the tradeoff is low stability and a bit of stiff/short dwell feel at stock weight.
With weight added: everything unlocks for the Quanta. Adding ~15 g total (about 7.5 g per side) deepens the sound, widens the sweet spot, and bumps both pop and power into the “very good power paddle” territory.
In my first session with added weight on the Quanta, I never once had to think about the sweet spot. The paddle felt stable, no dead spots, and I had zero complaints.
Funny enough, in blind sound tests with added weight, the Quanta sounded surprisingly close to a Boomstik. It was basically flipping a coin to guess which was which.
Weight set up to mimic the Boomstik
Versus the Ripple: Quanta feels better off the face, sounds better, swings easier, and produces pop more effortlessly. Ripple may drive a touch harder at its stock swing weight, but if you add lead to the Quanta to match swing weights, it likely drives the ball just as hard while still feeling easier to handle.
Compared to Boomstik: The Boomstik still has a bit more immediate pop and crispness out of the box, but a weighted Quanta gets impressively close. It’s still too early to make a complete comparison to the Boomstik, but for $100 versus $333, the real question is whether that last 10–15% of performance is worth paying three times more.
Quanta Technology & Core Design
The Quanta uses a new full foam construction that feels noticeably different from the Ripple. Instead of the soft, squishy foam that caused issues before, Ronbus has gone with harder pallets and a layered design aimed at boosting stability and pop.
Handle
As I mentioned earlier, Ronbus moved to harder pallets, so grips now feel thicker (~4.25") compared to some earlier models that felt closer to 4 1/8.
Core and Frame Highlights:
EPP Foam Core – Lightweight all-foam core built for power and pop.
EVA Ring – Surrounds the core to enhance both pop and energy return.
Carbon Grid Wrapped Edge Foam – A 3D edge grid designed to add spring effect around the paddle face.
Carbon Wrapped Edge Foam (Tube) – Reinforces the throat and handle for added durability.
Carbon-Wrapped EPP Handle – A stronger handle structure for long-term stability.
TPE Elastomer Inserts – Placed in the lower corners to dampen vibration and improve stability on off-center hits.
On court, this tech shows up as a paddle that’s lighter, quicker, and easier to swing than the Ripple, while still unlocking solid pop and stability once you add weight.
Final Thoughts - Who Might Like It
We’ll need a little more time to do comparisons to the othere full foam paddles like the J2NF, Bread & Butter Loco, and the Boomstik.
But for about $100, the Quanta is a very good paddle if you’re willing to add weight to it.
Stock, it’s light and a bit stiff. Add ~15 g and it jumps into the conversation with much pricier power paddles. If you were eyeing a Ripple, this is the one I’d recommend instead.
Choose your shape based on what you already play:
R1 (elongated, aero) – If you like Hyperion-style heads and want tip speed with reach.
R3 (elongated, square) – If you prefer a Perseus-style square face for a straighter contact zone.
R4 (hybrid) – Balanced reach and width if hybrid is your comfort zone.
R2 (widebody) – Stock swing-weight is the lightest; great if you want maximum maneuverability, then add lead.
R5 (widebody, longer handle) – Same idea as R2 but friendlier for two-handed backhands.
Pick Quanta if you:
Want a budget power paddle that becomes excellent with a simple lead setup
Prefer fast hands and easy acceleration
Like to tinker with weight to dial feel and stability
Want five familiar shapes at one price point
