Its very simple, when you visit the LS3/5a website click on the link which says Yahoo Group Mailing List which will take you to the page on YahooGroups server, on the page you will find the button "Join Goup" click that and fill the form on the next page and submit it. You will be notified by the Group Moderator about your being inducted into the group. Once you are the member of the group you can post messages. Response from the moderator may take a day or two but have patience you will eventually get a response. You must have a Yahoo ID to become a memeber, if you have one no problem but if not just follow the instructions when you try to join the group. It is a very easy and simple process with may take only a few minutes.
Coming back to your message, I do not think it is as simple as someone saying the subwoofer is impossible to integrate with speakers. Many fellow audiogoners are enjoying it. First of all one must accept the fact that none of the equipment we use is perfect, on top of that none of the rooms that we have equipment in is perfect, next comes our own hearing which as you may know is also not perfect, infact as we age it deteriorates. What everyone is actually doing is compromising on many many variables and tries his or her level best to make things acceptable.
One must experiment on his or her own and find the most acceptable set of components. I may like certain brand of speaker but my fellow audiogoner thinks otherwise and vice versa, that does not mean the equipment is good or bad, it is different sounding to each of us and our personal preferences come in the way. That's what makes this hobby so enjoyable and that is why we all come here to share each others experience.
As for amps, I have an older NAD which is just 25 watts per channel and is in service with my computer rig presently connected with a pair of Mission speakers. I have used this amp with the LS3/5a's and I thought the sound was very good. The Missions did not even come close to what the LS3/5a could do. On the other hand I have a large 300 watts Perreaux amp which I also used with this speakers and again I really enjoyed listening to it, there was a difference no doubt but the 25 watter did the job admirably. So if you have a 30 watt amp it should work. By the way which amp you currently own, if you do not mind my asking?
I realised you did not get an answer to your question: about 15 Ohms and 8 Ohms. All amp specifications generally are quoted for 8 Ohms into certain watts say 50 watts RMS into 8 Ohms. If you plug in the speakers with a 4 Ohm rating the output ideally should double meaning 100 watts. If a 15 Ohm speaker is connected the output becomes half, 25 watts. This is a very crude way of explaining but I hope you get the idea. You can always do a search on google and read about how amplifiers work and and what the impedence means. In real world there are always surprises
I look forward to your messages on the LS3/5a forums.
