75 litres and no port. The box does the damping.

Two walls of MDF around 75 litres of sealed air. Two 8-inch cellulose woofers, an 8-inch polypropylene midrange and a 27 mm textile dome, crossed at 700 Hz and 2.8 kHz through air-core coils and polypropylene capacitors. 91 dB and a smooth 6-ohm curve, so a modest amplifier is enough.

Walls: Double-wall MDF
Loading: Sealed, 75 litres
Drivers: 27 mm textile dome, 8-inch polypropylene midrange, two 8-inch cellulose woofers
Crossover: 700 Hz and 2.8 kHz, third-order HF, air-core coils, polypropylene capacitors
Finish: Black ash, bright ash or American walnut veneer

Matched for the load

Unitra KG-40 Speaker Cables

With a smooth but comparatively low 6 ohm impedance and 190 W RMS handling, the ZGZ-801 rewards a cable that adds nothing of its own to the equation. The KG-40 is Unitra's premium speaker cable, sized to keep the connection between amplifier and driver as neutral as the crossover itself.

Is the ZGZ-801 a bass-reflex or sealed-box design?

Sealed. The ZGZ-801 uses a closed, double-wall 75-litre enclosure with no port, which trades outright bass extension for tighter, more controlled low frequencies.

What amplifier power does the ZGZ-801 need?

It's rated for 190 W RMS and, at 91 dB sensitivity with a smooth 6 ohm load, it drives easily from modest solid-state amplifiers as well as tube amplification.

How many drivers are in each speaker?

Four per cabinet: two 8" cellulose-cone woofers, one 8" polypropylene midrange, and a 27mm textile dome tweeter, crossing over at 700 Hz and 2.8 kHz.

How much does a pair weigh, and do they need stands?

A pair weighs 74 kg. These are self-supporting floorstanders at 1188 mm tall, so no stands are required.

What finishes are available?

Natural wood veneer in black ash, bright ash, or American walnut.

Are these a reissue of a historic Unitra model, or a new design?

The ZGZ-801 is a new design built by the present-day Unitra company, which traces its roots to the original 1961 Polish Unitra works. It continues that tradition of Polish loudspeaker engineering; it reproduces no specific vintage model.

About the Unitra ZGZ-801 Floorstanding Speakers

Reference Floorstanders, Uncompromised

The Unitra ZGZ-801 Tower Speakers are reference floorstanding loudspeakers engineered for uncompromising performance. A meticulously crafted 75-litre closed-box cabinet delivers precise, controlled bass and exceptional acoustic stability, while a sophisticated three-way architecture with custom drivers ensures clarity, tonal accuracy and seamless frequency integration. High efficiency and a smooth impedance curve mean they pair effortlessly with virtually any amplifier.

A Sealed Cabinet for Controlled, Honest Bass

Unitra chose a fully enclosed, solid cabinet with an internal volume of 75 litres rather than a ported design — a deliberate decision in pursuit of tight, well-damped, time-accurate bass. Sealed enclosures roll off more gently and store less energy, so low notes start and stop exactly with the music. Built from two layers of MDF for rigidity, the ZGZ-801 stays acoustically inert so you hear the drivers, not the box.

Custom Three-Way Driver Array

Inside, custom low- and midrange drivers with rigid aluminium baskets and lightweight cellulose diaphragms work within an advanced three-way crossover to deliver outstanding clarity and coherence across the entire range. The combination of stiff baskets and low-mass diaphragms gives the ZGZ-801 its dynamic, effortless presentation — and its high efficiency makes it an easy, rewarding load for both tube and solid-state amplifiers.

Frequently Asked Questions

Are the ZGZ-801 sealed or ported?

Sealed. Unitra uses a fully enclosed 75-litre cabinet for tighter, more controlled and time-accurate bass rather than a bass-reflex port.

Will they work with my amplifier?

Very likely, yes. Their high efficiency and smooth impedance characteristics make them an easy load that pairs well with both tube and solid-state amplifiers.

What finishes are offered?

Real wood veneer in Black Ash or American Walnut, with a grille in black acoustic fabric or natural linen.
