Summary: I got this to use my XM Radio with in the house. The volume was right for me. I never mounted the receiver though because I brought the base with me to my two jobs as well as home. It got good reception for the most part. I ended up selling this on eBay for the same price I bought the new one for so you can't beat the price on Amazon at all. Overall it's a good product with a good pricetag.
Summary: I am very happy with the Altec Lansing XM3120. Sounds great for such a small item. I use it at work in my office so it's perfect since I don't need to play it real loud. Took it on vacation in our hotel room and it worked great. Does not get real loud but for a first time buy it works for me. Wish it did have a little more bass but still pleased.
Summary: Great product. I bought three of these units. I have one at the office, one at the shop and one at the pool. I do not have any problems with reception. This is a great unit. It was not meant for loud listening, simply as background sound. Adjust your expectations. I use it with the XpressRC receiver. I have XM radio preinstalled in my FX45 and with the receiver, the sound in my truck is just as good.
Summary: For the price--this is a great value and works great. I wish I'd spent more and got better sound quality though. Also, all the cords and antennae involved is messy and cumbersome to move around. If price is your goal, get it. If looks and sound quality are more important--spend more money.
Summary: Speakers produce excellent sound. Docking and undocking is fast and simple. I was impressed enough with this little guy that I ordered a second one for my work shop. The first one is in the living room. Due to our living room facing east I had to run the (long) antenna cable out the window and place it on the deck railing in a discreet area. This took all of two minutes and was a piece of cake. Shut and locked the window...done deal.
