Prince Diablo Prism is a round co-polyester tennis string built for low-powered control, good snapback and distinctive multicolor presentation. Each package divides the string into two equal half sets with different color combinations, allowing the mains and crosses to create a prism-like appearance.
The two halves use the same co-polyester material and gauge. This is therefore a cosmetic two-color installation rather than a hybrid of different string constructions.
Diablo Prism targets intermediate and advanced players with long, fast swings who want predictable trajectory and strong physical resistance. It offers impressive spin for a round string but very little free depth. The Tennis String Finder can help compare it with shaped and softer alternatives.
Prince Diablo Prism Rating
| Category | Rating |
|---|---|
| Power | 4/10 |
| Spin | 8.5/10 |
| Comfort | 5.5/10 |
| Control | 9/10 |
These ratings align with independent playtesting. Diablo Prism is an exceptionally controlled and physically durable co-polyester with strong round-string spin, but it is firm and very low powered.

Material and Construction
Diablo Prism is a single co-polyester monofilament with a round profile. Its construction is materially consistent across both colored half sets.
The Green-Blue and Yellow-Red sections create the visual effect when one is installed in the mains and the other in the crosses. Color does not establish a performance difference between the halves.
The smooth round exterior allows ordinary string movement and snapback. Independent testing found strong spin even without geometric edges, helped by pocketing and the low-powered response that permits fast swings.
Current product information does not consistently document a named low-friction coating. The string’s spin and resistance should therefore not be attributed to an unverified surface technology.
Prince Diablo Prism Performance
Power
Diablo Prism is extremely low powered. Independent playtesting gave it one of the lowest power scores among performance co-polyesters.
That restraint benefits players who supply pace through long, fast swings. It allows aggressive acceleration without the stringbed adding excessive depth.
The 17 / 1.25mm version is slightly more responsive and pocketed than 16 / 1.30mm. Neither gauge should be considered a source of easy power.
Beginners and compact swingers are likely to leave balls short or overwork to create depth. A multifilament, synthetic gut or livelier co-polyester is more appropriate for those needs.
Power rating: 4/10
Spin
Diablo Prism produces excellent spin for a round string. Independent testing found the combination of pocketing, snapback and swing freedom sufficient for heavy rotation.
The smooth profile lets the mains move without the directional restrictions that can occur when two sharply shaped strings intersect. The 17 gauge offers easier movement and ball interaction.
It does not provide the direct edge bite of Vortex Triad or Tecnifibre 4S. Players may experience a cleaner, more neutral contact while still generating substantial topspin.
Spin performance can decline as the intersections notch and the string loses elasticity. Physical integrity alone does not guarantee continued snapback.
Spin rating: 8.5/10
Control
Control is Diablo Prism’s strongest performance quality. Its low power and stable round response create a disciplined launch for aggressive hitters.
Independent testers reported confidence in both control-oriented and powerful rackets. The string lets players attack targets and create their own pace.
The feel is slightly muted rather than extremely crisp. Some players will appreciate the pocketing, while others may prefer the more immediate feedback of a premium firm co-polyester.
Control should be evaluated over time. Tension loss can raise launch or make the bed feel dead before the strong monofilament breaks.
Control rating: 9/10
Comfort and Feel
Diablo Prism is firm. Independent testers found some pocketing but gave comfort only moderate to low scores, with individual reactions depending on racket and reference tension.
The response is slightly muted and can feel stiff immediately after stringing. It may settle into a more pocketed character, but it remains a control polyester.
Comfort should not be overstated because one tester tolerated it well. Players with persistent arm discomfort should generally consider a softer material or professional setup guidance.
The 17 gauge can feel more responsive, while 16 gauge supplies a more substantial and demanding stringbed.
Comfort rating: 5.5/10
Durability and Tension Maintenance
Diablo Prism provides excellent physical durability. Independent testers reported minimal notching during their evaluation and rated resistance highly.
The 16 / 1.30mm gauge contains more material and is the better choice for frequent breakers. The 17 gauge trades some resistance for feel and spin access.
Physical durability is separate from useful playability duration. Independent results placed playability duration below physical resistance, indicating that tension and response can decline before breakage.
Replace the stringbed when the mains stop returning, trajectory changes or impact becomes unusually dead. The multicolor appearance can make wear visually distinctive, but color change alone is not a precise performance measure.
Choosing the Right Gauge
The two gauges provide the usual response-versus-resistance tradeoff.
| Gauge | General characteristics |
|---|---|
| 16 / 1.30mm | Greater stability, physical resistance and lower launch |
| 17 / 1.25mm | Greater pocketing, response and spin access |
Open patterns and breakers should favor 16 gauge. Dense patterns and players who restring regularly may prefer 17 gauge.
Full Bed or Hybrid Setup
Full Bed
Use one colored half in the mains and the other in the crosses to create the intended full Diablo Prism stringbed. Both halves perform the same material role despite their colors.
This setup maximizes the string’s low-powered control and distinctive appearance.
Prince Diablo Prism in the Mains With Softer Crosses
Diablo Prism mains with natural gut or multifilament crosses add depth and comfort while retaining round-poly control. This requires using a separate soft half set rather than the packaged second color.
The polyester can still notch the soft cross, though its round profile is less aggressive than a sharply shaped main.
Softer Mains With Prince Diablo Prism in the Crosses
Natural gut or multifilament mains emphasize power and feel. Diablo Prism crosses provide a firm, smooth support string and can help control the launch.
This is a sensible custom hybrid, especially with 17 gauge. It gives up the standard two-color full-bed design and remains firmer than an all-soft setup.
General Tension Guidance
Diablo Prism should generally start below the player’s nylon or multifilament reference. Its very low power does not require high tension to create control.
Players seeking pocketing can make a modest reduction. Those who prefer a firmer bed should adjust cautiously because the string already has a demanding response.
The 16 gauge, dense patterns and stiff frames can create a particularly firm combination. Gauge selection may be a better first adjustment than a large tension change.
Use the Tennis String Tension Calculator to establish a broad starting point within the racket manufacturer’s approved range.

Prince Diablo Prism Compared With Other Strings
Diablo Prism vs Prince Tour XP
Prince Tour XP is livelier and softer. Diablo Prism provides lower power, firmer control and a distinctive two-color presentation.
Diablo Prism vs Prince Tour XC
Prince Tour XC is another round control polyester, but it uses a documented high-molecular-weight low-friction coating and offers very thick gauges. Diablo Prism emphasizes pocketing and cosmetic identity.
Diablo Prism vs Solinco Hyper-G
Solinco Hyper-G uses a square profile for direct bite. Both are low-powered control strings, while Diablo Prism produces spin through smooth snapback rather than edges.
Diablo Prism vs Luxilon ALU Power
Luxilon ALU Power is a round premium co-polyester with a crisper and more responsive feel. Diablo Prism is firmer, more muted and considerably more visually distinctive.
Final Verdict
Prince Diablo Prism combines serious control performance with unusual cosmetics. Its two colored half sets are the same round co-polyester, creating one full stringbed rather than a material hybrid.
Independent evaluation supports its low power, excellent control, strong round-string spin and high physical durability. Comfort is limited and should not be softened by marketing language.
For advanced hitters who create their own pace, Diablo Prism offers strong value and predictable trajectory. The 17 / 1.25mm version adds response, while 16 / 1.30mm provides maximum stability and resistance.
