Ronbus Quanta Series Review

Ronbus Quanta Series Review Cover

Ronbus just reset the value bar. The Quanta Series arrives as a true power Gen 4 full-foam line that plays in the same arena as premium power paddles yet rings in around $99 after discount. No honeycomb anywhere, no core-crush drama, and performance that, once tuned, lands in legit power paddle territory and is the first budget paddle that is a real alternative to the power category leaders.

Tech, Shapes, & Specs Overview

Quanta X-Ray

Technology

This is the third paddle to feature a foam construction that I think will become very common: a solid EPP core surrounded by a ring of EVA foam, also seen in the Selkirk Boomstik and Bread & Butter Locos. While each has its own nuances, the x-rays highlight just how alike the designs are. On court, they share common traits as well. Very powerful, loud, and marked by a stiffer, more hollow feel. I will break down the differences in the comparison section below but they are all very good and are the top of the power category in performance in my opinion.

Paddle Shape Options

Ronbus is offering five shapes in the Quanta line. The variety is nice, but it can feel overwhelming if you are not familiar with their naming system. Here’s a quick breakdown of each shape with its key specs. Up front, I think the R1, R2, and R4 stand out as the best of the group thanks to their stronger twistweight-to-swingweight ratios.
  • R1 elongated, aero curve top
  • R2 widebody, squared top
  • R3 elongated, squared top
  • R4 hybrid, aero curve top
  • R5 widebody, aero curve top

Paddle Specs Table

The numbers are low across the board on these. Which makes these paddles light, quick, and easy to swing but also less stable and lacking plow-through until weight is added. For players who like to customize by applying tungsten tape, that low starting point is a huge advantage because you can dial in the stability and balance to your liking. But if you don’t like to customize and tinker with paddle setups then these may not be for you.

Playability Insights

Offense (drives, counters, putaways)

Out of the box, the Quanta sits in the middle of the power class. Drive speed is good, pop is present but not overwhelming. Add perimeter weight and it jumps a tier: the sweet spot firms up, contact gets “thuddier,” and ball speed off the face starts to flirt with upper-tier power paddles. Blind sound/feel tests on a weighted Quanta were surprisingly close to a Selkirk Boomstik.

Control (feel, drops, dinks, resets)

Energy in equals energy out. The response is linear, which makes targeting drops and dinks straightforward. Resets, especially out of the air, benefit from the even face feel. Weighting improves stability at contact and tightens dispersion. The pop level is on the higher end so the paddle doesn’t do much work for you here but if you can keep your strokes tight and have some sense of your own soft game then you can control these as well as any other power paddles in the high power class.

Feel wise it has a stiffer, hollower feel very similar to a gen 3 style paddle that isn’t full foam. So if you come from that style of paddle then this will feel familiar. However, if you prefer softer or a more dense impact feel then this isn’t that.

Forgiveness (sweet spot, stability)

Stock forgiveness is below average. You will feel some twist on blocks and off-center volleys due to the low stock swingweights and moderate twistweights. Perimeter tape at all four corners materially improves stability and sweet-spot size. Plus you can add as much as you need to get the forgiveness where you need it and are comfortable with. Some players will only need a small bump here while others will need to add a lot of weighted tape.

Spin

Spin is solid and my spin tests are above 2000 RPMs which is a good result. You notice a little less spin production without tuning but once stabilized with tape, the face hangs onto the ball a fraction longer and spin becomes more repeatable and helps manage the power of the paddle.

Maneuverability

This is the Quanta’s stock superpower. Very low swingweights make hand battles and rapid counters feel easy. Even after adding 12+ grams total, it stays quicker than most peers.

Customization: how to unlock it

These paddles are designed to be tuned. I liked the R1, R2, and the R4 the most and think they offer the best play so here are my recommended setups for those paddles if you need a place to start. I’ve only weighted these up to 8.2–8.3 ounces including tape and overgrips, so they’re still not heavy. But the twistweight and swingweight numbers are stronger than what you normally see on stock paddles around 8 ounces that get customized up to the same range.

Comparisons

  • Ronbus Ripple
    Quanta is lighter, easier to swing, sounds better, feels more consistent off the face, and matches or beats its power once weighted. Ripple becomes hard to recommend.
  • Ronbus Refoam
    This is Ronbus’ other full foam paddle that uses an MPP foam. It’s more of an aggressive control style paddle and is better suited for players looking for more control than the Quanta.
  • Honolulu J2NF
    J2NF has a bigger stock sweet spot. Quanta gets the edge on pop, power potential, maneuverability, and price. With weight, Quanta closes the forgiveness gap.
  • Bread & Butter Loco (similar foam core as Quanta)
    The Loco plays very similar to a weighted Quanta, but with a less hollow feel. Its stock weight performs well while still leaving some room for customization, whereas the Quanta really needs added weight to shine. If you like the idea of the Quanta but prefer a paddle that plays solidly out of the box, the Loco is the better choice.
  • Selkirk Boomstik (similar foam core as Quanta)
    Boomstik still beats out the Quanta in power and pop though it’s not by much, and it arrives pre-weighted and polished. A properly weighted Quanta gets surprisingly close in on-court results for a fraction of the price.
  • Body Helix Flik F1
    The Flik F1 outperforms the Quanta in peak pop, but the Quanta wins on control, maneuverability, and price. If your priority is maximum power with a softer feel, the Flik is the better choice. If you value speed in the hand and affordability, the Quanta is the choice.

Within the Quanta line:

  • Favorite: R2 (widebody square). Light, lively, controllable pop, and the most pleasant feel to me. Plus you can customize to be very forgiving while keeping the lightweight nature it has.
  • R1 vs R3 (elongated): R1’s flared head puts the sweet spot higher and gives more two-hand space. R3’s square face feels springier, with slightly more plow and a lower, larger sweet spot. The R1 has a better swingweight to twistweight ratio and can be customized better.
  • R2 vs R5 (widebody): R5’s flare raises the sweet spot and ahs more room for two-hands. R2’s square face feels more traditionally “widebody,” with a touch more plow. The R2 has a better swingweight to twistweight ratio and can be customized better.

Who’s The Quanta For?

The Ronbus Quanta is the new value benchmark in Gen 4 foam and in the power category. Stock, it is fast and playable. Weighted, it becomes a genuine power threat with a satisfying thud and a much bigger strike zone. Given the performance ceiling and the price, this is an easy recommendation.

Who This Paddle Is For:

  • Players who want real Gen 4 performance without paying premium prices.
  • Anyone who values maneuverability and is open to adding tape to optimize.
  • Intermediate to advanced players seeking middle-tier power with a clean, lively feel instead of muted foam feedback.

Who This Paddle Is Not For:

  • Players chasing the absolute top of pop/power (think Boomstik, Flik F1, GX2 Power).
  • Players who want a huge, plush sweet spot out of the box and do not plan to add weight (J2NF series or Loco remain strong there).

Paddle Terms Glossary

Paddle Type

We’ve categorized paddles into three categories. Control, All-Court, and Power. Paddle categories are determined by Braydon after he hits or reviews the paddle.

  • Control paddles offer a softer feel and better absorbs pace off the ball but doesn’t give you as much power.
  • All-Court paddles give you a blend of power and control and does well at everything though it doesn’t excel at anything.
  • Power paddles often have a firmer feel and will return more power but are harder to control.

A paddle’s weight represents the inherent mass of the paddle as measured on a scale. However, relying solely on this static weight measurement can be misleading when assessing the true perceived heaviness of the paddle. Even if two paddles both clock in at 8 oz, their actual heft in your hand can markedly differ due to variations in weight distribution within the paddle. This is why the static weight should be considered with the swingweight of the paddle. See the definition of swingweight below.

The weight value listed in the database corresponds to the paddle’s weight that I used to gather the swingweight and twistweight measurement. It’s possible that if your paddle has a different static weight than then the swingweight and twistweight may be slightly different.

There are three primary shapes a paddle can have which consists of the length and width of the paddle. These three shapes are:
  • Elongated: The dimensions for an elongated paddle are 16.5″ x 7.5″.
  • Standard: A standard shaped paddle has dimensions of 16″ x 8″.
  • Hybrid: A hybrid shaped paddle falls somewhere in between the standard and elongated shapes, with approximate dimensions of 16.25″ x 7.5″-7.7″.
Then there are two less common shapes you’ll see. These are:
  • Extra-Elongated: This shape is 17″ x 7″
  • Widebody: This any paddle shorter than 16″ long.
When considering the advantages and trade-offs of paddle shapes, it’s important to understand the characteristics of each shape.
  • Elongated Paddle: An elongated paddle offers increased reach, spin, and power. However, this additional reach comes at the expense of forgiveness, particularly from side-to-side.
  • Standard Paddle: In contrast, a standard-shaped paddle provides less reach and a little less power & spin but offers greater overall forgiveness. This means that while you may not have the same extended reach as an elongated paddle, you gain better control and stability.
  • Hybrid Paddle: The hybrid shape serves as a middle ground between the elongated and standard shapes. It provides a balance between reach and forgiveness, offering players a versatile option that combines aspects of both shapes.
It’s interesting to note that advanced players often prefer elongated shapes. On the other hand, players at lower skill levels typically opt for the extra forgiveness offered by standard shaped paddles. Ultimately, the choice of paddle shape depends on an individual’s playing style, preferences, and skill level. Whether your focus is on reach or forgiveness, understanding the unique benefits and trade-offs of each shape can assist you in selecting the paddle that best suits your game.

Swingweight is a measure of the paddle’s resistance to swinging about the end of the handle. The higher the swingweight number the heavier it will feel in your hands. A higher swingweight has more power but is harder to swing, lower swingweight is easier to swing but has less power. Sometimes a faster swing with a lower swingweight can make up for power lost in swingweight. The price paid for that is greater impact shock. Stock swingweights will vary between 100 – 140.

Twistweight is the resistance to rotating around the long axis through the middle of the paddle from butt to tip. The higher the twistweight the more resistance the paddle has to rotating on off center hits. This measurement is closely related to the amount of forgiveness or the size of the sweet spot of the paddle. A higher twistweight indicates a bigger sweet spot. Twistweight numbers range from 5 – 8.

Measuring the revolutions per minute (RPMs) off of a serve you get a number that shows the spin potential of a paddle. Using these RPM measurements I’ve created five buckets that a paddle will fall into indicating its overall spin potential. The five buckets are:

1900 or Higher = Very High
1700 – 1900 = High
1500 – 1700 = Medium
1300 – 1500 = Low
1300 or less = Very Low

You can tell a big difference in the amount of spin a paddle generates when you compare a Very High paddle to a low paddle. But the gains from Medium to High to Very High are marginal. We’ve found that having at least a medium rating is often enough if you’re looking for a good spin paddle. However, if you’re a big hitter then you will benefit more from a high spin paddle to help you keep the ball in play more often.

The power level of a paddle is shown in miles per hour (MPH) after taking ten measurements with a speed gun of hitting a serve as hard as I can. This measurement gives you an idea of how hard you can hit the ball when given the chance to take a full swing. So shots like serves, drives and overheads. The higher the MPH reading the more power you can generate with the paddle.

I also show the percentile ranking of the measurement to give you an idea of how it stacks up against the rest of the paddles in my database.

The pop level of a paddle is shown in miles per hour (MPH) after taking the average of ten speed gun measurements of hitting a punch volley as hard as I can. This measurement gives you an idea of how hard you can hit the ball on shorter swings and gives you an idea of how quickly a ball comes off the face when you apply less force on the ball. So shots volleys, dinks, counters, and resets are all affected by the pop measurement. The higher the pop measurement the stronger your counters will be but it takes more skill to keep the ball from floating or popping up on you when resetting a hard hit ball or when dinking.

I also show the percentile ranking of the measurement to give you an idea of how it stacks up against the rest of the paddles in my database.
