Dellichord FR6 – Big bass & difficult acoustic spaces

Huge bass & difficult spaces – Welcome to innovative acoustic engineering. The Dellichord FR6 Stand Mount Speakers are crafted for a great performance and huge bass even in acoustically challenging spaces. Engineered specifically so that no seperate subwoofer is needed. You will wonder “how does so much bass come from such a small box?“

Dual mid-bass drivers in isobaric formation – The secret is the dual, mid-bass drivers in isobaric formation and an oval passive radiator working together in a compact real wood enclosure.

Dellichord FR6 – Great living spaces can be difficult listening spaces

The main goal was to achieve a full-range, accurate, and detailed sound that could perform well even in difficult acoustic environments. This is especially true for our modern, open plan, tiled and glass living spaces, overly bright or damped rooms. The speakers needed to sound smooth and easy to listen to in our own homes. In this way, the FR6 speakers fit seamlessly into any space, blending classic sophistication with a fatigue free, live music experience.

Although aesthetics and tactile quality are important in loudspeakers, sound quality must always be the number one priority. In that regard, the FR6 uses high-quality drive units, crossover components, and ETI binding posts. The real engineering innovation is in the cabinet design, which allows the FR6 to achieve an exceptionally wide frequency response from a modest, bookshelf-sized enclosure.

The FR6 is a deceptively complex little speaker. It employs TWO mid bass drive units – one hidden inside the enclosure in an “isobaric” compound arrangement, and the other visible on the front baffle. On the back is an oval passive radiator that looks like another drive unit but actually provides turbulence-free, extra-deep bass instead of using a reflex port.

The isobaric arrangement allows for a smaller cabinet while still providing substantial low bass extension.The passive radiator avoids the “chuffing” or port noise of a port, again without requiring a larger enclosure.

These two main factors allowing the FR6 to reach deep into the bass range like a large subwoofer, yet it can easily fit on a TV cabinet or bookshelf.

Tweeter – has a wide surround 29mm soft dome offering a very sweet sound with every delicate detail of the music reproduced clearly. The dispersion pattern at higher frequencies is also less likely to excite reflections in modern rooms. It has its own small rear chamber which imbues it with a very low resonant frequency. The FR6 employs a relatively low cross over frequency of 1700Hz. Accurate third order filter slopes on both the bass units and tweeter allow the tweeter to perform flawlessly in a distortion free manner.

Stereo Imaging – The cross over is constructed (designed and assembled in-house) on a fibreglass circuit board. The goal is consistency to ensure stereo imaging is always as good as it can possibly be through perfect matching of one loudspeaker to the next. The components employed are of premium quality including metal film resistors, polypropylene capacitors and both air cored and P cored inductors.

Speaker stands – The size of the Dellichord FR6 speakers allows use on TV cabinets or shelves, however they will produce the most stable stereo image when properly positioned on quality speaker stands. Using stands also enhances the already impressively fast and agile base of the FR6. This is thanks to its 2-driver, 1-passive design.
