Solidsteel S4-4 Wide Four-Shelf Audio Rack - Black

The Solidsteel S4 Wide — Two Components on Every Shelf

This rack is 43.85 inches across, and that number is the whole idea. Each shelf takes two full-size components standing side by side, so a system spreads out sideways instead of stacking into a tower.

It shares its shelf spacing and its engineering with Solidsteel’s S3 racks, so the two lines sit together in a room without arguing. If you already own an S3, this is the one that matches it.

How Much Will a Forty-Four Inch Shelf Hold?

Two Hundred and Forty-Two Pounds a Level

Each shelf carries up to 242.5 pounds, which is the highest figure anywhere in the S range and a long way past what a pair of components weighs. The shelf is not being asked to work hard, which is how it stays flat.

Two Full-Width Boxes, Side by Side

A shelf 43.85 inches across and 19.9 deep takes two full-size chassis next to each other rather than one with wasted space around it. A monoblock pair can share a level, and so can a streamer and the amplifier it feeds.

Height Depends on Which One You Buy

The two-shelf rack gives a generous 12.8 inches between its levels, which suits tall gear. The four-shelf version fits more in and gives 9.6 inches between shelves, matching the S3 series. Measure your tallest component and pick accordingly.

Low and Long, or Tall and Long

The two-shelf stands 18.7 inches high and the four-shelf 35.6, both on the same 43.85 by 19.9-inch footprint. One sits under a wall-mounted screen; the other holds a full system without needing a second rack.

Filled Aluminum Under Laminated Shelves

A floor carries vibration upward and speakers add more of it through the air. A wide rack has more shelf to keep still than a narrow one, which makes what the supports are made of matter rather more.

Supports That Do Not Ring

The aluminum supports are filled rather than hollow, the construction Solidsteel developed across its flagship Hyperspike line and brought down into the S range. A hollow tube rings; a filled one has very little to return.

Rigid Shelves, and Spikes at the Floor

The shelves are rigid MDF under a polymer laminate, and the rack stands on adjustable spike feet that reach through carpet and level it on an uneven surface. Protective discs are supplied for hard floors.

Room to Breathe, and Room to Reach

Nothing encloses this rack: no back, no sides, no doors. Two components sharing a level still have open air above and around them, and heat leaves upward and sideways without meeting a panel on the way.

The width pays off behind the rack as well as on it. Cables from two boxes on one shelf have somewhere to go, and reaching an input on the back of either one does not mean moving the other.

Build It in the Room

It bolts together from shelves and supports, and Solidsteel publishes a step-by-step guide for the series, embedded below. The shelves are long, so clear the floor around you before you open anything.

Level the rack on its spikes while the shelves are still empty. A wide rack loaded with two rows of components is not something you want to lift afterwards to reach a foot underneath it.

Designed to Sit Beside an S3

Black shelves in polymer laminate on aluminum supports, with the same clean Italian lines Solidsteel uses across the range. The S4 shares its dimensional character with the S3 series, so the two lines read as one system in a room.

The style traces back to the company’s discontinued 7 Series, and the build draws on what was learned making the Hyperspike racks above it. It is the wide member of a family rather than a separate idea.

Solidsteel’s official installation guide for the S4 series, worth watching before the carton is opened:

Who Is the Solidsteel S4 Wide Best For?

• You have wall space rather than height — 43.85 inches across puts two components on every shelf instead of stacking them.
• You own monoblocks — a pair can share one level side by side, with 242.5 pounds of capacity underneath them.
• You already own an S3 — the S4 shares its shelf spacing and finish, so the two racks sit together as one system.
• You want the rack low — the two-shelf version stands 18.7 inches high and fits under a wall-mounted screen.
• You want to go further under a source — the shelves are a clean base for isolation feet beneath a turntable or DAC.

Pairs Well With

• A turntable — the top platform is long enough to take a deck and leave room for something beside it.
• Isolation feet and platforms — between a component and its shelf, for the one box you want treated separately.
• Power amplifiers — a monoblock pair fits on one level here, which a standard-width rack cannot offer.
• Interconnects — runs get longer on a rack this wide, so work them out from where each component will sit.

Frequently Asked Questions

How much weight will each shelf hold?

Up to 242.5 pounds per shelf, the same on every level. That is the highest capacity in Solidsteel’s S range and comfortably more than two full-size components weigh.

Will two components really fit side by side?

That is what the rack is built for. Each shelf is 43.85 inches wide and 19.9 deep, which takes two full-width chassis next to one another rather than one with empty space around it.

How much clear height is there between shelves?

It depends on the size. The two-shelf rack gives 12.8 inches, and the four-shelf gives 9.6 inches, which matches the S3 series. Measure your tallest component before choosing.

Will it match my S3 rack?

Yes. The S4 was designed with the same dimensional characteristics as the S3 series and the same MDF shelves in polymer laminate, so the two lines are meant to stand together.

How hard is it to assemble?

It bolts together from shelves and supports with the hardware supplied, and there is an official step-by-step video above. Allow floor space, because the shelves are long.

Will it damage my floor?

Protective discs are included to go under the adjustable spikes on hardwood or tile. On carpet the spikes can reach through to the subfloor, which is what gives the rack its footing.
