Speakers with acoustic spikes

 

— specially shaped poles used primarily in floorstanding speakers. In accordance with the name, such supports are made pointed, and it is precisely the sharp ends that rest on the floor; to protect the floor from damage, special small plates are usually used. Anyway, the meaning of such a design is to minimize the contact area of the speaker with the surface below it. This, in turn, increases the pressure at the points of contact and minimizes the so-called parasitic oscillations — vibrations transmitted from the speaker to the floor. Acoustic spikes are considered an almost indispensable element of equipment for outdoor Hi-Fi class acoustics — without such equipment, the mentioned parasitic vibrations can irreparably spoil the sound of high-end speakers and negate all their advantages. Note that spikes for speakers are sold separately; however, buying acoustics, originally equipped with such stands, is often easier than looking for third-party accessories.
