Question: how many watts is this unit?
Document: Basically, what transpired after was comical. I told her the situation, and I advised her that many others were having the problem, and she replied with a pre-written warranty statement that she pasted in. I told her I was past the warranty and had no problem paying for a repair, and she pasted in a pre-written statement about the repair not being possible because of the way the unit is sealed from the inside.
Having done our research regarding the IMT800 we figured lets buy it. Until now the unit was used about once every week for about 2 hours each time. The sound and features of the unit are quite acceptable. Unfortunately we were never able to get the batteries to work. As it turns out many others with this unit had the same issue. No big deal because we use it where there is power.The biggest issue is the recent one regarding the power adapter.
Let me begin by saying don't write too many reviews on Amazon; but I was simply amazed by my experience and figured I could do someone else a favor by passing it on.I purchased the iMT800 stereo, which is the previous model, about one year and four months ago now. The unit is nice and there are no issues in the aesthetics or sound quality, aside from the the midtones which are a bit lacking. But I would generally echo what others have said about the stereo sounding nice.
I was looking for something portable that still had powerful sound for use outdoors and compared many units. It came down to the 810 and the Bose portable and I went with Altec Lansing. While the Bose portable is smaller and delivers good sound, this unit is plenty powerful, has very good sound, and costs half as much. It may be bigger and somewhat bulkier than the Bose, but it's lightweight enough to tote around and the $200 I saved makes it all the more likable.
It's advertised as 200 watts of power, while the iMT810 (which was hard to find this info about, but 1 source states it) has 40 watts. It's power is the only thing I initially liked about the Beatbox, everything else I didn't particularly care for:  $400 price tag, no battery power (at 200 watts I could understand why) and only 2 sets of speakers.
I spent a lot of time researching ideas for outdoor speakers, wireless music solutions, etc. The shortcomings of most other products are that:1. They are not in stereo (one speaker or perhaps one small woofer and tweeter)2. The remote is limited to either the speaker volume, or to the signal's source (not both)3. They are only portable within range of their transmitter4. C'mon, where's the power? The majority of other solutions range from 5-20 watts rms.
They probably did it to cut down on weight and cost and really I don't plan on taking it many places that won't have an AC outlet close by, but still it would have been nice to have. I guess I can get rechargeables at some point.
As an audio engineer, sound quality is most important when purchasing any audio device. I purchased an iMT810 about a year ago and have been very pleased with it. The sound quality is excellent with massive low end response, and the 7-band EQ allows for more fine audio tweaking than many other similar products.
Unfortunately there are so many online resellers of our products, that do not necessarily purchase them from one of our approved dealers or retailers. A lot of resellers on Amazon sell used products, and we do not honor our warranty for units purchased through them. Firemall is not one of our authorized retailers. You may want to check with them directly to see what warranty they offer.
While I wish for the sake of those wanting to purchase one of these that the price were lower for you I think that the many glowing online reviews of this device and lack of anything besting it even after all this time has allowed for asking the increased price. I don't know what to say about that other than I hope it goes on sale. It is still a very relevant device and sounds awesome, that is for sure.
Answer: Not sure. DO not buy it,I had a lot of problems with mine and customer service stinks.First the screen went dark and now it has no sound at all.customer service said the unit is sealed and can't be serviced.
