Hi - firstly, I am not an audiophile, nor do I have a big, dedicated home cinema system. I have just purchased a Panasonic 28PS5 and use the digital out of my Sony 725 DVD player to get 5.1 surround. The issue is that the TV ignores (or seems to) the .1 channel, so there is no bass response. I spoke to some chaps in my local specialist hifi store about whether I could still attach an active sub to the dvd player - they thought so, then showed me some subs costing £200 which were the size of a small armchair. I figured this may be overkill! As an experiement, I noticed in the Argos catalog that they had a small sub (50-70 watts) made by Acoustic Solutions. This appeared to be the exact same sub sold by Richer Sounds as the Eltex Thunder 8 for £49 - same price as Argos. So, being an experimentalist and knowing of the Argos 14 day money back policy, I purchased one to see if the theory works. It does! Now, I haven't really spent a great deal of time setting it up but the low range constant "rumble" adds some LF depth to the TVs surround output and you can pretty much feel spaceships flying round in Attack of the Clones. The advice I need is this: should I stick with the experimentation model or would I now be better uprgading to the Eltex Atomic 8.2 for £80? For one, it has a higher power output and an auto off feature but for another, it comes in silver (same as the tv) and is only 5cm all round bigger than the current one which is 25cm all round. What exactly does the higher power output translate into? Louder effects? More room shake? Or does it just allow for better quality without distortion? As I mentioned, I don't really want a "super-duper" system - I really wanted something to just add that extra "umph" and give dvds the .1 channel they were missing. Any help would be appreciated. Cheers.
