Setup and Technical Overview
The VS3251 system is an analog 5.1 channel system consisting of five small speakers, each with a 2.5" full range cone enclosed within a sturdy molded plastic shell. To complement these we have a 5" medium sized subwoofer unit, which is of the front firing long throw breed enclosed within an MDF box, with the use of MDF being to increase tonal accuracy and natural resonance within the unit.
As is the case with most systems like this, the amp is housed within the sub unit and is good for 70 watts RMS all up, with 9 watts being sent to each speaker and 25 watts to the subwoofer unit. There are no detailed specs on amp choice and design listed with the product.
Frequency response figures are given as 40Hz-17KHz (-10db) with the minus ten meaning that anywhere within that range of 40Hz through until 17000 the signal may be attenuated by up to 10db, which is quite a lot. As a reference; figures are usually given with 'plus or minus' of 3db, so AL have generously given themselves an extra 7db of breathing room with those figures.
