When Harold Leak first introduced the original Sandwich design, it solved a problem that had troubled speaker designers for decades: how to make a cone that was simultaneously lightweight and rigid. The answer was to bond aluminium skins to a foam core — the same structural principle used in aircraft construction — creating a diaphragm that could move with exceptional speed and accuracy while resisting the flex and breakup that caused distortion in conventional paper cones.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 2025 Sandwich 100 carries that engineering forward. The 15cm mid\/bass driver is built around a Rohacell aircraft-grade structural foam core bonded with aerospace-grade adhesives between aluminium skins — a modern refinement of the original concept. A long-throw motor system with a high-gauss magnet and low-loss suspension ensures linear excursion at higher volumes. The 30mm coated textile dome tweeter is deliberately larger than is typical at this price point, enabling a lower crossover frequency and better power handling. The crossover is set at 2.2kHz using polypropylene capacitors and air-core inductors, developed through extended listening trials with accurate time alignment between drivers as the stated priority.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAcoustic design was led by Peter Comeau, IAG's Director of Acoustic Design. Comeau co-founded Heybrook Hi-Fi in 1979 and has overseen acoustic development across Wharfedale, Mission and LEAK since joining the IAG Group.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKey Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDriver complement: 15cm Rohacell foam-core Sandwich mid\/bass + 30mm coated textile dome tweeter\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSensitivity: 86dB\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eNominal impedance: 6 ohms\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRecommended amplification: 25–100W\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eBass extension: 44Hz (–6dB)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eEnclosure: Two-way rear bass-reflex vented box\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDimensions: 340 × 210 × (250+20)mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFinishes: Walnut, Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePairs well with:\u003c\/strong\u003e LEAK Stereo 130 (45W\/ch), LEAK Stereo 230 (75W\/ch), Audiolab 6000A (50W\/ch), Quad Vena III (45W\/ch) — all available from Audio Visual Revolution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesigned by Peter Comeau\u003c\/strong\u003e — IAG's Director of Acoustic Design, with over 25 years of award-winning designs across Wharfedale, Mission and LEAK.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"LEAK","offers":[{"title":"Default Title","offer_id":43331023732795,"sku":"LK-S100-WAL","price":1199.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0320\/1699\/0267\/files\/LEAK100Artistic6_I_2.png?v=1775622516","url":"https:\/\/www.avrevolution.com.au\/products\/leak-sandwich-100-loudspeakers","provider":"Audio Visual Revolution","version":"1.0","type":"link"}
