Videologic ZXR-750 7.1 Speakers review


With the growing number of DVDs supporting Dolby Surround EX and DTS-ES decoding and with newer soundcards featuring 7.1 Output, itís just a matter of time before the market gets inundated by 7.1 Speaker system packages.

Videologicís ZXR-750s are touted as the ďWorldís First Integrated 7.1 Speaker SystemĒ, which as far as I know they were until recently that Creative released a newer Inspire system to couple with their 7.1 soundcards, however, whatís even more attractive about the ZXR-750 is that itís not meant to break the bank but is offered at a very affordable price. Featuring ConnX.1 and SurFE, the ZXRís can also up-mix 5.1/6.1 input to 7.1 channels.


Out of the Box

Setting up the system itself wasnít much of a hassle, after taking everything out of the box, I was ready to position the speakers and connect them to the Subwoofer. Like with other budget systems, the ZXRís subwoofer houses the amplifier and inputs.

Connectivity wise, the ZXR-750 offers both auxiliary stereo inputs and multi-channel inputs via phono plugs. The choice of having phono inputs opposed to more common mini-jacks may seem a bit odd to those looking for use with a PC only, but indeed these can prove very convenient given that DVD players commonly feature phono outputs for stereo or even 5.1 output. So in either case Videologic has you covered.

Of some ironic note, true 6.1 output was unavailable with the Audigy 2 because this soundcard uses a single line-out to carry the 3 rear channels (which the Inspire 6700 happens to support) while no other soundcard outputs the rear channels in this way, e.g. the Revolution 7.1 uses a 4th line-out to carry the 2 Rear centre channels. The Hercules Digifire 7.1 & M-Audio Revolution 7.1 however connected just fine to the ZXR-750ís 7.1 channel inputs.



The Subwoofer comes in a rectangular, grey finished, wooden enclosure. Wood offers better quality bass and yields less distortion than other materials (at least compared to other similarly cheap ones). Design wise, its appearance hasnít changed from the ZXR-550, bar a proportionate increase in size and weight, that is.

As mentioned earlier, the Subwoofer enclosure houses the amplifier and all inputs on its rear. Thereís an Input select button located in the top left which allows you to switch between Auxiliary (AUX) and Multi-channel (X.1) modes. The ConnX.1 knob located just beneath allows you to select 5.1, 6.1 or 7.1, which will optimize the output for the specified mode.

The Front of the subwoofer as you can see isnít as crowded as the Rear, with only 4 volume knobs on it Ė Master, Centre, Rear and Sub. As with most multimedia systems it also uses a (dual) ported design (which provides improved bass efficiency at lower frequencies) as opposed to a down firing one, with the 2nd port located on the side. As far as performance goes, the subwoofer offers 28 Watts RMS of power and has a response range of down to 18Hz. The Subwoofer responded well enough during testing. At about 50% sound could get a little Ďboomierí although this could be compensated with ease using the separate Sub control.
