A point source inside a box

A full array in a small box is noise, not coverage.

The problem as it arrives from site

A request for A point source inside a box from Riyadh usually arrives as one short line: fit out the room. That line cannot buy a seat, a screen or an isolator. BoxTech turns it into clauses: count, pitch, material, exit path, and the relation to sound, structure or interior. A full array in a small box is noise, not coverage.

The reference count in this file is 18. It is not a claim that we installed that number in a named landmark. It is a specification target locked after the drawing. The photograph explains the room. The number explains the decision. If the drawing changes, the number changes.

Worked example: 1 rows × 2 seats = 2. Approximate row width is 2 mm when the index is not a millimetre pitch. The difference between this width and the real sector is absorbed at aisles and row ends, not by crushing the last seat.

What is checked before a price

A price on a missing clause is paid twice: once in the offer and once on site. We write what the drawing must show before we write a supply unit. In Riyadh, approval stalls when the seat, screen and steel contractors send conflicting schedules. This article puts the clause in one office.

First check sight or hearing, depending on the subject. Then the exit and the aisle. Then the material: outdoor polymer, tested cloth, galvanized steel, or an isolator with a cavity behind it rather than a thickness with no meaning. Then maintenance: the part replaced in year five without stripping the row.

A full array in a small box is noise, not coverage. That sentence belongs in the meeting note, not in the margin of an email. If the consultant rejects it, the clause is rewritten. It is not deleted to let the offer pass.

Sequence on the drawing

Start with the room boundary: walls, risers, doors and the control position. Place the first and last rows before repeating the module. Easy repetition is how mistakes happen: forty copies, then an aisle that is too narrow or a screen that covers the eye.

After the rows, place services: power, data, a hearing loop, ducts and hanging points. A service added after upholstery punctures the isolation. A service drawn with the seat stays maintainable.

Write the bill from sectors, not from one photograph. Bowl, box and accessible positions are different lines. One blended line produces a price that does not match what is installed.

How it sits in the rest of BoxTech

A seat does not live alone. A screen changes eye height. A line array changes roof load and what the front row hears. Isolation changes the door, the glass and the duct. A steel stand changes how the seat is fixed. Interior colour is chosen after the cloth sample, not before.

On a Riyadh file we ask for one meeting of these clauses before any family is supplied. The meeting is not an upsell. It stops a correct seat being installed in the wrong room.

An exhibition stand or a home cinema is smaller and the mistake is cheaper, but the order is the same: seat, path, sound, light, then strike or isolation as the type requires.

The engineering reading for this family

The sound in “A point source inside a box” at Riyadh is a class, not a badge. A line array is for a long distance if the roof can carry the hang and the cabinet does not mask the screen. A point source is for a box, a short hall and a booth. A full array in a small box is noise, not coverage.

The front row may need fill. A seat under a balcony may need delayed fill. The subwoofer is drawn with the seats, and on steel the vibration is reviewed so the chair does not buzz. A hearing loop is tested in the intended seat after the final floor, not at the door on opening night.

Tune with seats present, because cloth and bodies absorb. We do not claim a loudspeaker agency. The name is written as in its datasheet after the measurement.

Closing the clause

A good clause is measurable: a distance, a test, a spare and a signature. A weak clause is a brand name and a photograph. BoxTech does not let the name replace the number.

When you send the brief, reduce this article to the note: city, count, index and the key sentence. A full array in a small box is noise, not coverage. Then send the drawings. Without them the note is a description, not a quotation.

This is article 48 in the journal. The next one sits in the same family or completes the room. Read the table, the list and the mistakes before you move the clause into the study request.
