Paradigm Founder 100F Floorstanding Speaker, Black Walnut (Pair)

The Paradigm Founder 100F is a passive 3-way floorstanding speaker that combines three 18 cm Carbon-X woofers with an AL-MAG midrange driver and an AL-MAC tweeter into one big, balanced soundstage.

Why the Founder 100F?

Because the 100F closes the gap between affordable hi-fi and genuine high-end. It uses the same driver technologies and elaborate Cascade Fusion cabinet construction as the larger Founder models – just in a shape that fits a normal living room. Three woofers provide foundation and authority, while the midrange driver in its own chamber keeps voices free and open. This is technology from the Persona flagship class, brought down to a fair price.

What you hear

A wide, deeply layered stage on which the speakers themselves acoustically disappear. Voices stand tangibly between the cabinets, the treble is open and airy without ever turning harsh – even after hours. The bass is powerful but disciplined: it carries rather than dominates. With 93 dB sensitivity, the 100F reacts finely to good electronics and makes differences in the chain audible.

Who is the Founder 100F for? (and who isn't it for – straight talk)

For music listeners who want a fully grown floorstanding speaker with depth and fine dynamics, without investing in Persona territory. Straight talk: the 100F resolves mercilessly – on a weedy mini system it stays well below its potential. Hand on heart: if you save money here and hook the 100F up to a big-box-store amplifier, you're giving away exactly what you paid for. A solid integrated amplifier belongs with it.

Our verdict

The Founder 100F is one of the most coherent floorstanding speakers in its class: neutrally tuned, spatially impressive, and cleanly built. It goes toe to toe with considerably pricier models – anyone looking for a speaker that performs "well above its price" tends, in our experience, to end up sticking with the 100F. At HD Zürisee in Wädenswil we put together the right electronics to go with it and set everything up so the 100F shows its full potential.

What the trade press says: "Linear and superbly resolved in the midrange, a spacious, very open and involving sense of soundstage" – fairaudio, 2023. SoundStage! Hi-Fi lists the 100F as a "Recommended Reference Component".

Frequently asked questions

How big does the room need to be for the Founder 100F?
The 100F feels at home in medium-sized living rooms from around 20 square metres upward. Its three woofers need some distance from the rear wall to play cleanly. In very small rooms the bass can become overpowering – there, the Founder 80F or 40B is often the more fitting choice.

What amplifier does the Founder 100F need?
A fully grown stereo integrated amplifier with stable power delivery. The 100F handles 15 to 300 watts and, at 93 dB, is fairly efficient, but rewards good electronics with more resolution. Clean quality matters more than raw watts – we help you match the right amplifier.

Do I still need a subwoofer with the Founder 100F?
Usually not for music – three woofers and a frequency response down to 42 Hz provide a solid foundation. For home cinema with deep effects below 40 Hz, a subwoofer can make sense. We'll show you whether it's worth it in your room.

How does the 100F differ from the Founder 80F?
The 100F is the larger 3-way speaker with its own midrange driver and three 18 cm woofers, while the 80F is a more compact 2.5-way model. The 100F plays deeper, more authoritatively, and bigger, but needs more room for it. In smaller rooms the 80F is often the smarter choice.

Why buy the Paradigm Founder 100F at HD Zürisee?
Because a high-resolution speaker only shows its potential with the right electronics and placement. We advise you on amplifier, cable, and positioning, and deliver and set up on site on request. With years of experience by Lake Zürich, we make sure the 100F sounds at your place the way it's capable of sounding.
