THE PARK TENNIS TAKE

The useful truth, in plain English.

Original editorial judgment · evidence below

The net is not taller on Tuesday night. It only feels that way after the third forehand clips the tape. The SX 300 is Dunlop's 100-inch, 300-gram answer: swing up, clear the net, and let the ball come down with bad intentions. Its open 16x19 bed rewards shape from the baseline and on second serves. Hit flat and casual, and the launch can develop weekend plans. This racquet wants commitment. Give it one more foot over the net and make the bounce somebody else's problem.

BEST FOR

Intermediate and experienced baseline players who create topspin and want easy net clearance, useful power, quick handling, and a heavier bounce.

SKIP IF

You hit mostly flat, prefer a low launch, dislike a firm response, or want the directional quiet of a thinner control frame.

BEFORE YOU BUY

SX is the lineup. The 300 is the standard racquet: 100 square inches, 300 grams unstrung, 16x19, and 27 inches. Tour has a 98-inch head. LS and Lite remove weight.

Teal and yellow is a lineup, not a receipt.

SX models share paint and most of a name. The year, SKU, head size, weight, pattern, string state, and grip confirm the exact racquet.

ON-COURT PERSONALITY

The net is where the ball begins its climb.

OFFICIAL + PLAYTEST + TWU

From the baseline

Topspin, depth, and net clearance define the response. The open bed helps the ball climb and fall, but exact-model testers found launch could vary when the swing stopped supplying enough shape.

On serve

Kick and slice get the obvious invitation. The frame also supplies useful pace, especially when the player commits to a target instead of asking spin to make every decision.

On return

The measured 318 swingweight keeps the racquet quick enough for reaction work. Big targets and added shape matter because a flat aggressive return can use the available power to leave early.

When contact wanders

The widened hoop and grommet system are designed for stability and spin beyond perfect center contact. The response remains firm, and the open launch still asks the player to manage the face.

THE RACQUET GENOME

Its personality, without the fake precision.

These bands combine specifications, professional reviews and documented player experience. They will get sharper as the evidence does.

THE NUMBERS, TRANSLATED

Specs are only useful once somebody tells you what they mean.

HEAD SIZE

100 sq in

The 100-inch performance middle. More usable room than Tour, without stepping into an oversized forgiveness frame.

UNSTRUNG WEIGHT

300 g / 10.6 oz unstrung

The standard 300-gram SX. Enough mass for a settled response, with a measured swingweight that still keeps upward acceleration practical.

STRING PATTERN

16x19

An open 16x19 bed engineered for string movement and snapback. It rewards shape and can raise launch when contact gets flatter.

FAMILY POSITION

The SX everybody means

The lineup center that carries the spin, net-clearance, and power brief without changing head size, length, or standard performance weight.

BALANCE

320 mm / 7 pts head-light unstrung; 4 pts head-light Tennis Warehouse strung sample

Dunlop lists 320 millimeters unstrung. Tennis Warehouse measured a strung sample at four points head-light and 318 swingweight, a quick but not flimsy middle.

LENGTH

27 in / 68.6 cm

Standard adult length. The difference from Tour, LS, and Lite is not hidden extra length.

STRINGS + SETUP

Let the racquet make spin. Let the strings keep the meeting orderly.

The retailer-published range is 45 to 65 pounds. A comfortable multifilament around 52 pounds is a straightforward first setup. If you already use polyester successfully, start lower and record the exact string, gauge, and tension before changing anything else.

THE WIDER TENNIS CONVERSATION

Everyone finds the spin. The disagreement begins after the ball clears the net.

REVIEWS · VIDEO · OFFICIAL SOURCES

AGREE

THE CONSENSUS

Dunlop, the four-player Tennis Warehouse test, TWU measurements, and the selected exact-model video agree on high spin, useful power, quick handling, and a baseline-first personality.

THE LIMIT

Launch and feel are personal here.

The same open response that produces margin and shape gave some testers inconsistent depth, and the firmer feel did not suit every hand.

THE OPEN QUESTION

Do you create shape already, or are you hoping the paint will handle it?

Choose the SX 300 when an upward swing is already part of your normal ball. Flat hitters should pay particular attention to launch, while players wanting more precision should compare the 98-inch Tour.
