Pro-Ject Speaker Box 5 Bookshelf Speakers - Piano Black

Pro-Ject Speaker Box 5 Bookshelf Speakers - Piano Black

Compact 2-way bookshelf speakers in a high-gloss Piano Black finish, built for tidy stereo systems with proper hi-fi intent

The Pro-Ject Speaker Box 5 is a compact bookshelf speaker designed for customers who want a genuine stereo setup without needing a large cabinet or a visually heavy speaker in the room. This version is the single Piano Black finish variant of the original Speaker Box 5, and as a discontinued model it now makes more sense as an archived or limited-availability listing rather than a current multi-finish product. Pro-Ject described the Speaker Box 5 as an audiophile 2-way monitor using a bass reflex design, aimed at clear, dynamic sound from a compact cabinet.

It uses a 25mm silk-dome tweeter and a 130mm fibreglass woofer, with published specs listing a 55Hz to 20kHz frequency response, recommended amplifier power from 10 to 150 watts, and a compact cabinet size that suits smaller lounges, apartments, studies, or neat turntable-based systems. The Piano Black finish is one of the stronger parts of the appeal here, because it gives the speaker a cleaner, dressier look than a standard vinyl wrap bookshelf design.

Compact Size, Proper Stereo Sound

Compact format for a conventional stereo system

The Speaker Box 5 was built for customers who wanted something compact, but not cheap-feeling or throwaway. Pro-Ject’s original positioning focused on it as a proper 2-way monitor speaker with bass reflex loading, rather than a decorative lifestyle speaker with very little substance behind it.

The Speaker Box 5 was designed for a conventional stereo role and pairs naturally with compact integrated amplifiers, turntable systems and other small-format hi-fi components.

A Straightforward, Easy-to-Live-With Design

Clean cabinet proportions, simple amplifier matching, and sensible room use

Published specs list an 86dB sensitivity, 4 to 8 ohm impedance, and recommended amplifier power from 10 to 150 watts. In real terms, that makes the Speaker Box 5 easy enough to match with a wide range of sensible stereo amplifiers, especially in smaller to medium-sized rooms where a compact standmount is the better fit anyway.

The cabinet also keeps things practical. The rear reflex port, single-wire gold-plated terminals, magnetic front cover, and included flat wall-mount bracket all point to a speaker designed to be easy to integrate into real homes.

Piano Black Finish, Discontinued Status

A cleaner single-finish listing without the old variant clutter

For this listing, the important point is that this is the Piano Black version only. Older listings referred to multiple finish options across the wider Speaker Box 5 range, but this page should stay focused on the single gloss black model you actually have. This listing is presented in Piano Black.

Because the model has since been succeeded by newer Speaker Box versions, This earlier Speaker Box 5 generation remains a conventional passive standmount design and should be matched to a suitable amplifier.
