The Edifier 1280db also has digital inputs that allow for higher fidelity sound and easy connection to modern audio sources with lossless connectivity.I realize that wood finish isn’t for everyone, but the neutral grey grills do tone down the finish and give it a more balanced appearance, where they don’t feel out of place in most home environments. Instead, the Edifier R1280T is a great choice for someone who wants to move away from built-in TV speakers to something with more clarity and diverse frequency response. They are also ideal for a desk setup. They pair very well with most vinyl players, especially given the aesthetic of a lot of vinyl players, which look to retain the 70s style wood grain finish. Removing the grilles reveal a 4” bass driver and ½” tweeter, as well as flared bass reflex port. The right (active) speaker, also houses a series of controls to dial the speaker tone across both bass and treble, independently. It also offers a single volume control dial.

The R1700BT is composed of MDF and wood, and the R1280DB is composed of MDF. However, both speakers are really sleek and modern looking, and they certainly look like more ‘high-end’ speakers. Features They are incomparably better than the R1700DB and R1280BT to a point that I wouldn't even consider buying the previously mentioned ones. The dome tweeter helps with the high frequencies, and the bass driver helps with the lower midrange. The tweeter is set at a higher frequency so as to not be drowned out by all of the other noise that may exist in your environment.

The R1700BD's were my least favorite speakers, I'd probably choose the R1280's over them if I had to, the treble sounded decent, but not too shabby. No bass, vocals sounded muddy, sounded quite narrow, definitively wouldn't recommend. Both have a 4-inch woofer with a treble driver though a bit smaller on the 1280DB, which has a silk dome measuring 13mm, unlike in R1700BT, which has a silk dome measuring 19mm. Because of this, the R17900BT outputs slightly better high frequencies, but its nothing too noticeable. These dials are able to control the bass between a range of -6 and +6, and the same ability is provided to the treble. Sure, it’s not going to allow you to fully EQ your speakers, at least not with the help of additional software or hardware, but it does provide versatility and an easy way to get your speakers to the place you want them to be for your intended use. n terms of the design and shape, both of them are almost similar to one another. As you take a look at both left and right sides, you would agree that they are almost equal to each other.
