SVEN SPS-707 speaker system: review and testing

Cheap multimedia systems often attract buyers only by price, but for SVEN SPS-707 it is hardly applicable term. Classical speaker system in format 2.0 is hardly interested for the modern audiophile, but being a source of high-quality sound for the office or student discos such a solution is very suitable.

However, for audiophiles often have strange things such as Audioquest ethernet-cable for $ 2,200, a device for demagnetization of CDs or electron irradiation of the same CD for a "dramatic improvement of the quality of pictures and sound."

Let's finish on this lyrical pause and consider the devices for real life and its radical sound improvement - SVEN SPS-707.

Testing sample has a price range of $ 100, which means good sound at an affordable price. That is the best opinion, 2.0 or 2.1? In this review, we will try to find it out.

Package and content 

SVEN SPS-707

Package of SVEN SPS-707 is very substantial, so even in case of unpacking it becomes clear that we bought a serious thing. The right side of the box has a picture of the device and the mention of its main features: the use of three independent audio inputs and availability of separate control of timbre of low and high frequencies. A good tool is a presence of the remote controller, coupled with the control unit on the top panel. Company SVEN did not forget to mention the material of the case (MDF), and the fact that the front panel speaker is glossy.

One of the side faces contains sufficiently detailed technical specifications, which are also listed in the table above specification.

Another side of the package has listed equipment and a photo of the control unit on the top panel.

Package includes everything you need to run the system. Speaker cables, remote controller with batteries, two cords 2 x RCA 3,5 mm are included.

Design  

SVEN SPS-707

 

System SVEN SPS-707 is large enough and its two speakers will take about the same amount as a CRT monitor of fifteen years ago a small aquarium. In general, the device is large and requires a lot of space.

If the desktop does not have enough space, the speaker can be placed under the table due to arranged block with the controls on the top panel. The glossy front panel looks stylish, but some it quickly is covered with dust and fingerprints.

Two-way speakers use body is made of fiberboard made according to MDF technology. As already mentioned, the front panel is made from glossy black plastic, and the speakers are not covered by the protective nets.

The base of the speakers is a rubberized stands that lift them a few millimeters above the surface of the table.

The control panel has four buttons and LEDs quartet that functionally replaces the remote controller. It is logical that they are multifunctional. Thus, the power button not only turns on and off the sound, but also switches the current signal source. Button «Mode» switches between volume and control of low and high frequencies. And the buttons "+" and "-" change the above parameters. The control panel lights up with multiple LEDs for indicating adjustment. For example: “Channel DVD” – “low frequencies.”

Remote controller is much easier to use to configure the audio than the control panel on the speaker: each of the adjustable parameters have the right buttons that do not overlap and do not create unnecessary confusion. Everything is simple and seamlessly.

Nevertheless, it should be noted that the termination of the power supply completely drops all user settings by the factory ones. In other words, if you turn off SVEN SPS-707 not from the control panel or remote control, but disconnect power from the network, all your settings (volume, bass and treble) will be dropped, so all you have to configure them again.

The back of the speaker contains jack of removable power cord and power switch, two pairs of RCA and mini-jack socket (AUX) for different sound sources. Spring terminals are used to connect the left satellite to the amplifier block, located on the right.

LF speaker basket is stamped and magnetic system is ventilated. Its size seems quite adequate for the speaker of this price range. The speaker has the nominal impedance (4 ohms) and power (20 W).

Lion's share of the control functions is given to audio processor PT2313L. According to the documentation it has the following features:

  • LF and HF tuning;
  • volume function;
  • 3 stereo inputs with selectable input gain;
  • Input / output for external system of noise reduction / equalizer;
  • control of four independent speakers to the rear and balance;
  • volume control in steps of 1.25 dB;
  • low distortion;
  • low noise and low DC;
  • control via bus I2C.

In general, all of the features in SVEN SPS-707 are implemented by this device, which is selected even with the stock functionality.

Amplifying part is equipped with radiator to dissipate the heat inside the case. Taking into account phase inverter design and low total power, this decision seems justified.

Actually, the audio amplifier is implemented as a chip TDA7265, which in addition to sound-amplifying capabilities contains mute function and mode «Stand by», i.e. standby mode to save power.
