Finally I bought F&D A520 through flipkart.
Frankly, I bought this 2.1 for movies and so I am happy. As far as its performance in music is concerned, it appears cannot even defeat Creative SBS A300's bass and treble reproduction. I am telling again, I am very happy as it delivers excellent midrange as well as clear sharp deep bass.
Let me say the reasons and see the comparisons below after my testing. I have been using SBS A300 for 4 years.
SBS A300 Vs F&D A520 ---->
- Mix of Tight and Boomy bass Vs slightly Boomy bass with fully lacking tight bass.
- Average midrange Vs Excellent midrange reproduction. This makes movies much real and enjoyable.
- Average deep bass clarity Vs Sharp deep bass clarity (theater feeling.)
- Fair treble reproduction Vs just average treble reproduction.
- Overwhelming bass Vs Well balanced bass and impressive midranges (Makes overall listening experience stunning)
No tight bass. Such a bass range appears not reproducible by the subwoofer. I remember many songs that has tight bass sounds as well as vibrations clearly pronounced by SBS A300, but completly disappearing in A520. Maybe the sub specializes in deep bass only (20Hz to 120Hz), then the upper bass end probably suffers. Those deep bass and vibrations SBS A300 struggled to reproduce are well heard and clear in A520. Overall in my view, this makes A520 not up to the mark for music. However the deep bass makes movies real and we feel we are in a theater. It also males us think the frequency reproduction gap between sub and satellites is somewhat large to get noticed while listening.
For the money we pay, this is excellent for movies and may not be good for music. Also a refreshing experience for all who used Creative in the past days.
It is also clear that from its specs... A520 will behave like this. Build quality is excellent and amazed to see the stuff.
Also since the bass is not tight, we may have to give more bass via SRS trubass, DFX etc for a heart thumping bass from the sub. I think, tweaking equalizer bands can affect a frequency that is reproducible and cannot affect that is not reproducible at all.
Anyway, I really really enjoy it for movies.
