As a rule, floor-standing speakers are used in home theater systems, often front, sometimes rear, rarely center. During operation, vibrations from the speaker cabinet are transmitted to the surface where they are installed, causing unnecessary resonances and overtones. One way to combat these resonances and improve the sound of your speakers is to mount them on spikes. Expensive imported speakers, as a rule, are initially equipped with spikes, but, unfortunately, not always. Domestic acoustics usually does not have spikes. In audiophile stores you will always be offered sets of spikes in beautiful packaging at a price of $50 per set. If you are ready to pay this money for them - you should not read further, buy and experiment. Putting your hands on, the same result will be achieved at a price of $ 2 per 1 column. So, let's start with the spikes.

Thorns

The spikes are conical in shape, with an angle at the top of about 30 degrees. Having a familiar turner, you can easily solve all problems by simply ordering him to turn them. Material - steel, brass. The tip can be slightly hardened. Fastening - bolt, embedding in a hole, or gluing to the surface. In the latter case, it is convenient to use "double-sided tape", but you should have the largest possible diameter of the landing area. Since this design does not have a fine adjustment of the installation height, for a stable position, the installation is made on 3 spikes around the perimeter of the bottom of the column. Since the center of gravity of the column is usually shifted forward, it is advisable to install two spikes in the front corners and one in the center of the rear side of the bottom.

If the lathe is a problem for you, you can take a little walk around the hardware and hardware stores and purchase a plumb line. So, get acquainted - a construction plumb line. During a short survey of stores in Moscow, three types of it were identified (perhaps there are more of them).

Construction plumb line, Russia, 15 rubles.

In the end part it has a hole with M10 thread with fine pitch. Fastened by partial penetration into the hole in the column body and a bolt or glue.

It has a rough, poorly finished surface and a 50 degree angle. The surface can be ennobled, at home, with an electric drill and sandpaper. Recommended as a last resort.

Construction plumb line, Russia, 30 rubles

Features a well finished anodized finish, 35 degree taper angle, and multiple mounting options. In a blind hole with a diameter of 18 mm, in a through hole, and gluing to the surface. Due to the rather large length, you will probably just have to cut off part of it with a hacksaw or increase the thickness of the bottom of the column by gluing and screwing a piece of chipboard.

In the figure, options 1 and 3 - the ball is cut off at the end, 2 and 4 - part of the plumb line is cut off (a more time-consuming option). Recommended for speakers of medium size, and with a thickness of the material of the bottom and walls of the speaker more than 24 mm.

Painting plumb line, China, 30 rubles.

For large, heavy speakers - this is what you need! Medium quality chrome plated surface, 35 degree angle. Due to the large area of the sole, it is easy to install by gluing. The sole has an M10 threaded hole with a standard pitch, which makes bolting possible.

Its height is about 7 cm, weight is about 200 gr. With small speakers, it will look a little awkward, but by the way, everyone has their own tastes...

Roses

And now you just have to calculate how many roses you can give your wife with the money saved! They should be purchased immediately. Perhaps this will soften her horror at the holes in the floor that these spikes will leave. By the way, sometimes it's a good idea to put a small but heavy marble slab or coins made of hard alloy on the floor, under the spikes.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

clay bullets 11.12.2006

During the excavations of the large ancient Syrian city of Hamukar, from which only a mound fifteen meters high has survived to our time, an expedition of Syrian and American archaeologists discovered more than 1200 clay shells with which the attackers fired at the defenders of the city with slings.

The battle was so hot that the slingers did not have enough prepared ammunition, and they dug clay right on the battlefield, making shells out of it. They were not fired, so many clay "bullets" flattened upon impact were found. The battle raged 5500 years ago.

Judging by the change in the style of ceramic vessels found in shallower layers of the soil, the city was captured and inhabited by newcomers from the southern Mesopotamian city of Uruk.
