Hola chicos. I think (with all respect) that it depends a lot of your liking and also your room. In my experience, some rooms eat a lot the high frequency energy and the add of a tweeter firing to the speaker's back and pointing to the ciling, opens the sound and image. Helps to open the scenario. But I think definitively, depends a lot of your room. If you don't like them, it is o.k. too. Trust your ears and liking. In some rooms, also, I have notice that if it is too bright, you need to disconnect them, the transparency is more evident without the tweeters, but what do you want? What do you like? Again, depends on your liking. The ones that have tweeter, play with them, playing solo music, will be much easer to tell and try to image the scenario with and without them, then choose the ones that you like most!
Happy listening, trust your ears!
Thanks Everyone !!!!
I was to hear if you were missing anything by not using it, I believe David mentioned he used it only when people were around. Which is exactly what I thought you might say... if you can sit in the sweet spot "who needs it" but when moving around or when others are over it gets a "maybe". If anyone has more to say if would love to hear it.
