Overview
The LEAK Sandwich 250 is a three-way vented-box standmount loudspeaker that revives one of British hi-fi's most celebrated ideas. LEAK, founded by Harold Leak in 1934 and now part of IAG, built its reputation on the Sandwich cone principle, bonding light, stiff aluminum skins to a foam core to create a diaphragm that stays rigid and free of coloration. The Sandwich 250 carries that engineering forward with an 11 inch aluminum-foamcore Sandwich woofer, a dedicated 4.25 inch aluminum-foamcore Sandwich midrange, and a 1.2 inch coated textile dome tweeter, all wrapped in a mid-century cabinet finished in real walnut veneer with aluminum trim.
As a true three-way, the Sandwich 250 splits the work at 470Hz and 3.1kHz, giving the midrange driver a clear vocal band while the large woofer handles the low end down to a bass extension of 32Hz. Sensitivity is a healthy 88.5dB and nominal impedance is 6 ohm, dipping to a 4 ohm minimum, so the design is friendly to a wide range of quality integrated amplifiers. Recommended amplifier power spans 25 to 250W, and peak SPL reaches 112dB for effortless dynamics in a real room.
This speaker suits the listener who wants a full-range voice from a stand mount, retro styling with genuine engineering behind it, and a natural, uncolored presentation that works equally well with acoustic music, vocals, and larger scale material. Optional matching stands are available to complete the look and set the drivers at proper listening height.

How the Sandwich 250 Compares
LEAK Sandwich 250 vs LEAK Sandwich 150
The Sandwich 150 is the two-way model in the range, pairing a single Sandwich woofer with the dome tweeter for a compact, room-friendly footprint. The Sandwich 250 steps up to a three-way layout with a larger 11 inch woofer and a dedicated midrange, adding low-end extension, scale, and greater dynamic headroom. Choose the 150 for smaller rooms and nearfield listening, and the 250 when you want fuller reach and a bigger presentation. See the LEAK Sandwich 150.
LEAK Sandwich 250 vs Spendor Classic 4/5
The Spendor Classic 4/5 is a compact two-way in the British monitor tradition, voiced for intimate, vocal-forward listening and easy placement in smaller spaces. The LEAK Sandwich 250 takes a different path with a three-way array and a large Sandwich woofer, favoring full-range scale and dynamic weight. Pick the Spendor for a refined nearfield character, or the LEAK when you want more low-end reach from a stand mount. See the Spendor Classic 4/5.
LEAK Sandwich 250 vs MoFi Electronics SourcePoint 10 Master Edition
The MoFi SourcePoint 10 Master Edition uses a concentric driver for coherent point-source imaging and a modern, high-output character. The LEAK Sandwich 250 pursues a classic multi-driver three-way layout with its signature Sandwich cones and mid-century styling. Both are substantial stand mounts, so the choice comes down to the coincident-driver soundstage of the MoFi versus the traditional voicing and heritage look of the LEAK. See the MoFi Electronics SourcePoint 10 Master Edition.
Recommended Amplification and Source
A loudspeaker needs an amplifier to make sound. These same-brand and catalog pairings suit the Sandwich 250's 6 ohm load and 25 to 250W power range.
- LEAK Stereo 230 Integrated Amplifier The natural full-range partner, delivering 2 x 75W into 8 ohms and 115W into 4 ohms with the higher ES9038Q2M DAC, giving the three-way Sandwich 250 plenty of grip and matching styling.
- LEAK Stereo 130 Integrated Amplifier A same-brand match with 2 x 45W, ESS Sabre DAC, MM phono, Bluetooth aptX, and HDMI ARC, ideal for a tidy single-box system in a small to medium room.
- Audiolab 7000A Integrated Amplifier A sister IAG integrated with ample power and a capable built-in DAC, providing clean control over the Sandwich 250's larger woofer for a versatile all-in-one system.
- LEAK TruStream Network Streamer A matching source with built-in ES9038Q2M DAC, Roon Ready, Tidal, Qobuz, Spotify Connect, and AirPlay 2, feeding the amplifier a high-resolution signal via balanced or RCA outputs.
- LEAK CDT CD Transport A dedicated CD transport that pairs with the DAC in the Stereo 130 or 230 to add disc playback in matching style; note it has no built-in DAC of its own.
