Review on Edifier R1280T Active Bookshelf Speakers - 2.0 Stereo Near Field Monitors - Wooden Enclosure - 42 Watts RMS - Ideal for Studio Monitoring by Duong Mac Anh Quan ᠌

1. From a personal perspective, there is a congestion in the upper midrange. When the muffled mids transition into the brilliant highs, the result is a sound that is somewhat compressed. Because the columns are brand new, it is possible that it will take some time for the speakers to "warm up." However, judging by the comparisons of the sound of this model with other manufacturers (there is a channel on YouTube with comparisons of the sound of different speakers in different musical genres), a blockage of the upper mids will still occur. This conclusion was reached after listening to the sound of various speakers produced by a variety of manufacturers. 2. An unusual tone control for the bass. When a signal with a frequency of 50 Hz is applied, adjusting the location of the bass control from its minimum to its maximum setting does not significantly affect the level of the output signal. Yet, when a signal with a frequency of 100 Hz is applied, the change in sound pressure level that results from adjusting the location of the bass control can be heard very clearly. It seems to be some kind of selective low-pass filter, which does not affect the low-end frequencies that are very low, but rather solely controls the midbass. P.S. The problem described in claim 1 was partially fixed by increasing the value of the capacitor that was located on the tweeter from 3.3 uF to 6.8 uF. This capacitor functions as a high-frequency filter of the first order. As a result, the tweeter started to pick up some of the upper midrange. Once you have used the speakers for a while and allowed them to warm up, you could find that the capacitance requires a minute adjustment in the opposite direction. How things turn out is up to time.
