In fact, your power amplifier is better than the speaker. The power of A407 is not high.And your amplifier still supports 7.1, and you can configure a better speaker in the future.
3.9-4.2M This machine is very bad. It is the cheapest LCD home projector in the Chinese market at present. I hope it can help you. I suggest not to buy it,
My family used Philips 5590, and later upgraded it to wireless home theater. Because the budget was limited at that time, I wanted to buy a more reliable brand[Detailed]
The brightness is high enough for home use.The photo display effect is good.The overall effect was OK.
Disadvantages:
The display effect of the movie is not as good as expected. When I bought it, there was a Samsung A600B in the seller's shop. My TW3300C was the first one he sold. I tried the machine. The TW3300C and A600B were put together to play Avatar movies together. As a result, the display effect of A600B was better. The TW3300C felt that there was a layer of mist in front of the image, and the color was not as pleasing as A600B.The machine is nearly half as big as A600B and weighs much more.
Summary:
It's time to buy and leave. I don't compare with Samsung A600B, so I feel uncomfortable.It costs several thousand yuan and has no practical effect.The bulb is more expensive than A600B, and it needs regular dust removal...When I went home to use it, I felt that the effect was very good without the comparison of other machines. The brightness was very high. When the dynamic contrast was turned on, the living room didn't need to turn on the lights.
