Why bury a subwoofer in the garden? Here’s why!

by Olaf Adam
Music consists of high and low frequencies, and the more compact a speaker is, the harder it is for it to reproduce deep frequencies. That’s why speaker systems with additional subwoofers have long been established; in home theaters, of course, but increasingly in stereo setups as well. Only when it comes to providing sound for the garden and terrace is the bass usually neglected – but why, actually?
5.1 in the living room, 2.0 on the terrace?
If you equip your house with a multi-room system these days, you usually plan at least one outdoor listening zone for the terrace or garden. After all, you want to enjoy your music there too during the summer months – just as comfortably as in the other areas of your cozy home. There are plenty of solutions available for this, from weatherproof built-in speakers to wall-mounted speakers, and even discreet sound transducers in (artificial) stone designs. However, most of these speakers are rather compact and lack true bass capabilities. Special subwoofers for outdoor use can help here, but for some reason, these are rarely actually used. It would be a perfect fit, though, because nowhere else can you implement effective low-frequency support as discreetly and well as outdoors.

Perfect conditions
First of all, outdoors you don’t have to worry about one of the major acoustic issues you usually face within your ‘own four walls.’ Those very ‘four walls’ reflect sound, and at frequencies determined by the distance between them, standing waves or room modes are created. Especially in the bass range, you mostly hear the room, not necessarily the music itself. This problem logically doesn’t exist outdoors, which means – and strictly speaking, only here – you can achieve an unadulterated, authentic sound.
Definitely no space problems
Another challenge that needs to be solved when placing a subwoofer indoors becomes extremely simple outside. A decent subwoofer is inevitably quite large and not always easy to integrate unobtrusively into the room’s furnishings. This problem is incredibly easy to solve in the garden or on the terrace. For one thing, the sub can be hidden in planters or other objects. Even simpler, though, is just burying it.


Pure music
Apart from the fact that, with the right music and volume, such a solution might actually be effective at driving away pesky burrowing critters, it’s worth dispelling a common prejudice here. A subwoofer in the garden is definitely not just for ‘party people’ who want to annoy their neighbors every weekend with thumping bass. Quite the opposite. Every kind of music contains low-frequency elements that compact speakers simply can’t reproduce. If you really want to hear the entire recording, you can hardly get around using a subwoofer. This is especially true, for example, for classical music or jazz, which normally use the full audible spectrum without constantly featuring intrusive ‘boom-boom bass.’ Here, an outdoor subwoofer significantly enhances the listening experience – especially at low volumes, where the lack of bass from conventional speakers is particularly noticeable.
