Front- and down-firing subwoofers

Downfire or frontfire? This question comes up sooner or later when you’re planning to buy a high-quality home cinema system and need to decide on the design of your future subwoofer. Not only your personal taste should influence this decision, but also the placement options and the layout of the room. We’ll help you choose the right subwoofer.

Design of a downfire subwoofer

The design of a downfire subwoofer is intended to use the floor as a reflective surface. This allows such a subwoofer to be placed even in locations that might not seem suitable for a subwoofer at first glance.

From the outside, downfire subwoofers look like closed blocks. Only on the underside does the speaker cone or dust cap become visible. The cone is therefore directed downward – and that’s exactly the secret of downfiring. The low-frequency vibrations of the cone are directed toward the floor and reflected directly there. This distributes the signal more evenly throughout the room and significantly reduces areas with weak bass – known as room modes.

Frontfiring and bass reflex as enclosure designs

With frontfire subwoofers, the cone radiates sound forward or sideways, just like conventional speakers. Frontfire subwoofers therefore need space for sound output. The sound reaches your ears directly on the shortest path, without reflection. The result is extremely precise and punchy bass.

Reading tip: Here we give you tips on how to place your subwoofer.

Both downfiring and frontfiring subwoofers can also be designed as so-called bass reflex enclosures. In this case, the cabinet includes an additional tunnel-like port. When the speaker cone radiates sound waves backward through its movement, these are amplified by reflections inside the enclosure and in the tube-like port. Both the position and size of the bass reflex port, through which the sound exits into the listening room, are precisely calculated. The subwoofer enclosure acts as a Helmholtz resonator. With downfire subwoofers, the bass reflex port can be located on the underside of the cabinet or on the side panels.

Which is better: frontfire or downfire subwoofer?

Whether one enclosure design is better than the other can’t be answered in general terms. It depends on the performance parameters and the intended place of use as to which design is more suitable. You’ll find more tips on placement and positioning of your subwoofer in our video tutorial:

Teufel also offers subwoofers individually. Standalone subwoofers are ideal for combining with existing systems or for building a custom home cinema setup. Below is a short overview of some Teufel subwoofer models:

▶ T 6 subwooferOpens in new tab: This compact subwoofer delivers concentrated power with plenty of deep bass. Its small size doesn’t compromise the sound. With a cutoff frequency of 31 Hz (-3 dB) and a maximum volume of 96 dB, it delivers impressive performance.

▶ The flat subwoofer T 4000Opens in new tab also uses the downfire method. Thanks to the clever arrangement of no fewer than three drivers, the T 4000 is extremely slim and even fits under sofas. The subwoofer can be combined with almost all systems.

Conclusion: downfire subwoofers for room-filling bass

• When it comes to how subwoofers radiate sound, a distinction is made between downfiring and frontfiring.
• A downfire subwoofer directs the sound waves straight toward the floor. The sound waves are reflected immediately, creating an even signal throughout the entire room.
• The subwoofer can also be placed close to walls and directly next to or underneath furniture.
• With a frontfire subwoofer, the speaker cone radiates bass forward, just like a conventional speaker. The bass reaches your ears on the shortest path and therefore sounds especially precise and punchy. However, this type of subwoofer requires free space in front of the cone.
