Update: All 5 shapes of Quanta are in stock, no delayed shipping.
Tomorrow’s the day, the Ronbus Quanta series goes live for pre-order at 8 am EST (the paddle is going to ship on 9/12). MSRP is $119 ($99 with code RCCREQLW). All are 16mm, ~7.8 oz, raw carbon face, and full foam core (EPP + EVA ring). You can grab it for just $99, the first budget EPP foam-core paddle available tomorrow. Vatic Pro V-SOL (Pro & Power) will release at the end of the month, and Project KiwiCore will drop in the second week of October. Early orders also get a free Ripple-style cover. More details on the Quanta series and how it compares with the other foam paddles. Link
My take (Quanta R4.16 test notes):
My setup
- I’ve been gravitating to hybrid shapes lately, so I went with the R4.16.
- Stock weight 7.75 oz. I added 5 g at 4 & 8 o’clock and 2 g at 2 & 10, ending at SW ≈115 / TW ≈6.95.
Feel & power delivery
- Overall muted, slightly dense impact, clean energy transfer without harshness.
- Power builds with swing speed rather than trampoline pop, so drives and put-aways stay controlled.
Launch angle
- Out of the box, the ball comes off on a mid-low launch, making it easy to keep drives down and attack through the court.
- With the added head weight, launch drops a touch further, and contact feels more composed on flat counters; opening the face adds arc when you want it.
Stability & forgiveness
- Blocks and counters are very solid; near-edge contact holds up well, credit to the perimeter build.
- Put-away power is there when you pressure the ball; the face stays composed on fast exchanges.
J2NF vs. Quanta (and where J2FC+ fits)
- The 5.5" handle with a generous taper (plays like ~6") is notably more comfortable than my J2NF’s 5.3" shorter/smaller taper.
- J2NF: Noticeably stiffer and hotter. It carries more plow-through and free power on swings, a larger “central” sweet spot, and a louder, crisper impact. Launch tends to run a touch higher, so drives jump off the face with less effort. Blocks feel rock-solid, but touch requires a lighter hand.
- Quanta: Feels more maneuverable with a lower stock swingweight, quicker hands, easier wrist action, and it whips the ball more on rolls and counters. Impact is plusher/muted (no fiberglass interlayer), so dinks and drops come off more predictable with finer depth control. The R4’s balance plus foam damping gives better through-contact stability and less top-hand fatigue. All court paddle, power is there, but it’s more linear as it scales with swing speed rather than trampoline pop. Perimeter forgiveness is steady, though the “hot core” effect is less pronounced than J2NF.
- In overall feel, Quanta sits closer to J2FC+ than to J2NF, with more dwell and plushness, a softer on/off throttle, and a calmer sound/feedback profile.
Boomstik comparison
- Quanta is not even closer to Boomstik. Boomstik is denser and louder, and sits in a different tier for overall feel and price.
- If you’re chasing the closest Quanta analog, it’s the R1.16 shape: elongated with a curved top and lively leverage.
- Quanta is much more plush, more maneuverable, but lacks the power and spin of the boomstik. I believe it's still outstanding for the price point.
Spin & touch
- The raw carbon face grips well; the foam core makes dinks and drops predictable.
- Early verdict after two sessions, the value-to-performance is excellent. I’ll post a longer review after more court time.
- The low stock swingweight makes small additions meaningful without sacrificing hand speed.
Shapes:
- Quanta R1.16 (16.5x7.5): Elongated curved top (reach + maneuver)
- Extra reach with quick acceleration; aero curve keeps swingweight modest (SW of 108) while preserving stability. Good for overheads, drives, and singles leverage.
- Quanta R2.16 (16X8): Widebody (biggest sweet spot, block machine)
- Largest effective sweet spot; most forgiving on blocks/resets; quick at the kitchen. The Flat curve brings more twist weight to the series for torsional stability.
- Quanta R3 (16.5x7.5): Elongated, Flat Curve, heavier swing (big power)
- Heaviest ball off full swings; favors power players who like plow-through. Slightly higher TW than the R1.16, but the most swing mass for put-aways.
- Quanta R4 (16.25x7.25): Hybrid (balanced all-court)
- “Goldilocks” all-court profile; blend of reach and stability with easy customization headroom. Great if you want one paddle that does everything well.
- Quanta R5 (16x8): Widebody aero curved (lighter and forgiving)
- Very forgiving and stable with a slightly quicker tip feel vs R2.16 (flat-top widebody); excellent for counter-punching and hand battles.
