This is a review I left under my wifes name under "Altes-Lansing iM-237" review. I am also leaving it here for those of you who might need another speaker option.
After a long and lengthy research process here on Amazon, Youtube, and many other "review" sites, I narrowed it down to these two speakers. Unable to make up my mind, and didn't want to get buyers remorse, I decided to buy both.
The short version of this review is the Altec iM-237 is the winner here in my opinion. The reasons for this are in the "long version" to follow.
I recently recieved a Zune HD player (love it!). I am an active outdoorsman who spends alot of time hunting and fishing in remote areas, but love my music when I get back to camp. Hense, the need for a small, portable speaker.
If I,(you) were to buy the X-mini only, we would both be very happy and impressed with it. For such a small unit it really puts out nice sound. The built in rechargable battery is a nice option, but for me, in some of the areas I camp, I do not always have access to a 12volt charging source. It seems well built and the option of connecting these speakers with more speakers is another nice option I think. Like I said earlier, if I just bought this speaker, I would be happy, but when compared side by side with the Altec, big difference.
The Altec is larger than the X-mini, (little larger than a can of tuna), and comes with a nice, somewhat hardside case, the mini, a little cloth bag. The Altec is another well built speaker. This one runs on 3 aaa batteries which for me is more flexible than a rechargable unit. Run time has yet to be determined since I have not had these units long enough to find out.
I plugged the Altec into the X-Mini to make it easier to do my side by side comparison. I cranked up the volume and turned on the speakers, first the Mini. Wow, impressive, handles volume well, heck the dang thing vibrates all over table! a little tinny, mids were ok, bass was ok too. I turned down the Mini, which has its own volume control,(nice), and turned on the Altec, Wow times two!. It seem to fill the room with a much richer, deeper sound that was instantly noticable vs the Mini. I continued this back and forth, one on, one off experiment with a wide variety of music and it just kept confirming Altecs better sound. Actually, the best sound achieved was when I had both speakers on at the same time, incredible!
In conclusion, I think you would have to buy 2 Minis to out due the Altec, but if I was going to buy 2 units, I would buy another Altec and a splicer.
Hope this helps!
