Floor acoustics is a system that has significant dimensions (especially vertically) and is installed directly on the floor, without involving any additional devices. The main distinguishing feature of such devices is a higher sensitivity compared to shelf counterparts. However, a floor standing home audio system will only work properly if you provide it with a powerful amplifier, otherwise you will just get big speakers.
Such devices can be equipped with two, three or more frequency bands, but not in all cases the number of speakers corresponds to the “cavity” indicator. Very often, manufacturers equip their systems with two "woofers", then it is called 2.5-way.
Let's try to identify the most distinguished models by presenting to your attention a small review of speaker systems from famous brands.
Sonus Faber Amati Anniversario
About this system, you can safely say: "Made by hand in Italy." Even a cursory glance at this model will be enough to say that we have extremely high-quality and good acoustics from a famous brand.
Spindle-like from the top and lute-like in profile, this serious structure is assembled from twelve carefully matched maple blocks and fastened with a patented adhesive with vibration-absorbing composition. Active acoustics with a section of this kind eliminate the occurrence of standing waves, plus everything, will provide the user with excellent damping of the "cabinet".
The manufacturer offers its fans only two finishes - black (graphite) and wood (violin). Like the great creators of the perfect instruments Stradivari and Guarneri, the brand hides from prying eyes the formulation of its varnishes, adhesives and subtleties of technology, emphasizing that the home audio system, in fact, is the same means of playing music as the violin. That is why this model was named after the violin maker Andrea Amati from ancient Cremona.
Model specifications
Sonus Faber is equipped with a double ring tweeter with an overall diameter of 25 mm, without ferrofluid, but with a beam-optimizing element. The sound efficiency corresponds to the "open acoustic chamber" scheme, that is, the design of the 150 mm midrange driver is done using the principles of Kellogg and Faraday.
Active acoustics is equipped with two 220 mm woofers with aluminum-magnesium cones plus a coil with a significantly increased stroke length. Each head is unloaded on its own phase inverter port and is located in the rear of the structure. All phase-amplitude characteristics are balanced, and the value of the inputresistance optimized for crossover frequencies of 350 and 4000 Hz (optimum acoustics). Reviews about Sonus Faber are extremely positive, and they are left by both ordinary users and music lovers, so this modern creation can be recommended to everyone.
T+A KS 300
The 300th model was made the flagship of the entire series. The system turned out to be quite compact and somewhere even elegant with dimensions of 95 cm (height) and 19 cm (width) - stylish, simple and of high quality.
This floorstanding speaker embodies the concept of a common approach to sonic signature and know-how in technological solutions. All components that were involved in the design of the model are a continuation of the original T + A series and, at the same time, the unique developments of the brand's engineers.
The body is made of extruded aluminum, which provides the entire structure with rigidity and steadfastness, and thanks to the exquisite solutions of local designers, the acoustics, speakers, and the whole appearance are saturated with elegance and high cost.
The side walls of the cabinet are dampened with a proprietary material that is able to absorb any sound, while dampening vibration for the entire structure, and at the same time reducing resonant vibrations.
The woofers are matched to the millimeter according to their parameters to the total volume of the case. Due to the carbon fiber reinforcement of the cones, the output is ultra-deep and extremely accurate low-frequency sound, even despite the volume level.
Series specifications
Mid-frequency performance easily covers the entire vocal range from 200 to 2000 Hz, turning the sound into a dynamic, natural and incredibly lively instrument of perception. The diffuser, made using the latest GreyCone technology, has special notches that free it from any resonances, and due to the flexible suspension, the operation of the moving system is completely controlled and has an excellent sound overview. Acoustic systems of this kind have not yet been invented, and the legendary T + A ring tweeter can cover frequency ranges up to 40,000 Hz and even higher without any effort. The overall sound picture looks dynamic, airy and fast, without any trace of harshness or harshness.
A carefully calculated crossover filter involves dividing the frequencies into three bands. It uses only the finest quality components and meticulously optimized performance. The filter does not allow loss of linearity of speaker movements and keeps the sound within the established range limits. As a result, even large and heavy-duty signals do not present any difficulties for a three-way system. KS-300 is an excellent model and excellent acoustics. Reviews about the system are mostly positive, the only thing that users complain about is the modest color scheme, but this, as they say, is not for everybody.
Vienna Acoustic Beethoven Baby Grand
This model from the famous Grand brand can also be called the flagship of the company. "Beethoven" is a reflection of superioritythe entire line of acoustic systems "Vienna", which allows you to enjoy excellent sound both at large concert venues and at home.
The model turned out to be dynamic, open and extremely musical, because the device combines two 6-inch speakers with a low frequency, one with a medium frequency, and the tweeter with a silk cone completes it all.
Features of the model
The sound from the speakers is transparent and natural, and the mids and highs are perfectly balanced. The whole picture is complemented by two bass loudspeakers, where an amazing balance and uniformity of sound opens up to the user. "Beethoven" is a really high-quality, modern and simply beautiful acoustics. Reviews about the model are entirely positive, so it is extremely difficult to find any critical points or nuances. Some owners complain that the system's feet are too sharp and scratch the parquet, but this is easily solved with a small rug or the principle of "put it down and don't touch it".
Opera Seconda
Acoustics "Marshal" pleased us with the model "Opera". Just like in previous lines, a "closed box" was used as the sound design for this series. The new model has received some visual updates, but the principle of design has not changed, and why change something that works great.
Good speaker adopts 2.5-way design, and the mid-woofers were co-designed withScanspeak. The cones are covered with high-quality aluminum with the addition of mastic to further reduce resonances. The drivers are molded into the cabinet and have a reinforced construction.
System specifications
The treble section is equipped with a silk diaphragm and an innovative cooling system that uses ferrofluid, and the operating range of the radiator has an increased figure of 30 kHz. It is also worth noting that the amplitude of movement of the working diaphragm is almost 1 mm (twice as much as competing analogues), allowing high-frequency emitters to reach a higher level.
The tweeter is practically insensitive to any vibrations that come from other speakers in the system. All this is due to the resonant frequency (860 Hz) and because of the thick front panel (30 mm). Separating acoustic filters of the second level have excellent circuitry, which is made on two separate boards and is located at a considerable distance from each other. This is done in order to reduce the unpleasant effect of the mutual induction of the coils, and in addition, it allows you to get rid of the microphone effect.
All structural elements are carefully selected and tested at all stages of production, so we can say with confidence that Opera accurately transmits the musical signal and correctly builds sound stages (surround acoustics). Reviews about the model are entirely positive, so there is simply nothing to complain about, maybe only the price, but all high-quality speaker systems are subject to this “ailment”.
Epos M 16i
"Epos" is a floor-standing 2.5-way acoustics with a phase-inverted type. The model looks equally good both as a stereo system and as a home theater. The series features an improved 25 mm aluminum dome tweeter, ferrofluid coil cooling and a fine ferrite magnet, greatly improving the transparency of the sound compared to its predecessors.
Speakers
The mid-range driver (140 mm), together with a polypropylene cone, is built into the structure next to the tweeter and separated from the low frequencies by a special section. The speakers work in the optimal frequency range thanks to the first order filter (one tweeter - one capacitor).
The woofer is distinguished by the presence of a dust-proof matrix instead of a phase distributor, and the port of the phase inverter brought to the rear of the structure has symmetrical tubes to reduce the turbulence of the sound flow. The design also includes bywiring, and all key terminals are located on an anodized aluminum frame.
Yamaha NS 777
Yamaha's NS series speaker set is a three-way bass reflex floorstanding speaker in a stylish and distinctive cabinet. The model has a Waveguide horn design, which means the presence of woofers with reinforced PMD membranes and high-end proprietary wiring from Monster Cable. This allows the system to reproduce the most complex digital audio signals and accompany movies with any music source.
In addition to excellent technical performance, the Yamaha speaker set has a specific and at the same time elegant design, which has been recognized by millions of fans of the brand. The case is made in black polishing with a light speaker insert, which is typical for the brand's products.
The size of the mid-range speaker remained the same from the previous lines (130 mm), the sensitivity (89 dB) and the frequency range frames have changed - 30-35,000 Hz. The rated power of the system does not exceed 100/250 W with a resistance of 6 ohms. There is also a Bi-Wiring function and detailed filter settings. The model is perfect for both professional and amateur needs.
