I've used this for the last 25 years or so. I use it on a regular 2ch set up for both my TV/movie viewing and my main music. It has both the power to kick @ss and the smoothness to make you forget there is even a sub in play depending on the source.

This is my configuration, I found this position is more natural as it mimics having main speakers with large bass drivers anyhow. Like I said having dual subs flattened out my freq response in my room vs just one sub. My mains have side firing woofers so that helps the soundstage really well.

I'm not leaving my humble 2-way stereo for a fancy multi-channel setup (at least in the foreseeable future) BUT consider the addition of a subwoofer to my actual rig if that proves worthy.

Would any of you gentlemen share with me your practical experience on this matter

Two years ago I was in your situation: I'm very happy with my stereo set-up, although it is not necessarily that humble (a hybrid tube amp and a 3-way DIY speaker set at the heart of it). Sometimes I felt the lower end a bit lacking, so I got me a modest subwoofer.

The frequency range of my speaker set started at about 30-35 Hz. Not bad at all, but sometimes - and especially when watching films with the sound over my Hifi system - I felt something could be better. Now I added a subwoofer with a frequency range of 20 to 200 Hz and an adjustable Cross-over frequency of 50 to 150 Hz. I hesitated to get its bigger brother (with a range starting at 16 Hz), but I'm very happy with what I have now (a Magnat Monitor Sub 201A). Both for music and for films this - for the moment - convinced me that I don't need a fancy 5.1 or 7.1 multi-channel system. So, I would say: go for it - no need for a big investment, but it does make an interesting and enjoyable difference.

Depends. If you listen to music in stereo there is not much difference. If you listen to DVD audio with 5.1 mixes, maybe.

Subs may help if you're watching action movies and stuff is getting blown up. But to hear that in all its glory you need a surround sound setup.

Sorry, can't agree with these statements. I can hear a stark difference be tween no sub and sub while listening in stereo. You don't NEED a surround setup. And to be honest, most viewing spaces aren't exactly set up for a true surround system so you're really just making yourself feel good by saying "I have a 5.1 or 7.1 system". Of course, if you have the $100,000 and excessive room space to build a real theatre system, then god bless you.

Properly placed acoustic treatment will give you better sound than just randomly adding a sub.

I have two 600 watt subs that I can phase differently to enhance my listening room acoustics. But this is not for everyone. But I cannot fathom listening to any two channel system without at least one sub. Aside from the loss of lower bass extention, the dynamics of the music would suffer without one. Oh, and I have bass traps.

Agree with not for everyone and bass traps.

Curious, do you have 6", 8", or greater thickness on your traps and are they floor to ceiling in all corners? As a recording engineer I'm sure you did it right.

6 inch. And I just threw them down where they sounded good. No science involved at all.

Well, No one says that you have have big wattage to get some effect, or a designated listening room with acoustic treatments. A small sub between 70-150 Watts makes a big difference to the sound of a two channel system. For a small investment, the sound of a system can be vastly improved upon. Just don't crank it to 11 as the sub will not keep up. And there's no hard set up involved.

Describe 'treatment' please.

Absorption and diffusion.

Google "acoustic treatment" if you're interested.
