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
A small bookshelf speaker that still feels like real hi-fi
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.
That matters because speakers in this size bracket can easily drift into background-duty territory. The Speaker Box 5 was clearly aimed at a more serious stereo role, especially when paired with compact integrated amplifiers, turntable systems, or 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. Australian retailer listings described the finish as High Gloss Black or Piano Black, which is commercially close enough to present cleanly as Piano Black for the page.
Because the model has since been succeeded by newer Speaker Box versions, this page should read as a discontinued / archived product listing or a limited old-stock style product page, not as a current active-range speaker.

The Audio Experts Take
The original Speaker Box 5 makes sense for someone chasing a compact stereo speaker that still looks clean and sounds like a proper hi-fi product. The Piano Black finish helps here, because it gives the speaker a more polished, dressy look than a lot of budget bookshelf designs, and the size makes it easy to work into smaller living spaces without the setup feeling oversized.
As a discontinued model, this is really about sensible value and tidy system building rather than chasing the newest release. Pair it with a good integrated amp or a compact turntable setup and it still makes a lot of sense for a neat two-channel system that looks sharp and does the basics properly.
