I decided to open up the insides of my Soundcore Rave Neo. Everything looked well built. However, I noticed there was no crossover to filter the high frequencies from the woofer. There was only a capacitor to protect the tweeter from low frequencies. This may have been done to keep the price lower, in sacrifice of sound quality a little bit. So, I took a crossover I had laying around and installed it. After I slapped the speaker back together I gave it a sound test. Unsurprisingly, this modification did an excellent job of separating the treble and the bass, resulting in a much more natural and higher quality sound.
I would recommend trying this if you own a Rave Neo or similar (I assume this could also be done on the Rave Mini, Trance, Trance Go, Rave, Mega) , your warranty period is over (disassembling would make you void of any warranty), and you know what you’re doing. It really helps the sound!
As requested by @Unnamed and @ktkundy , here are some photos of the inside of the Rave Neo. All separated from the outside world by 16 screws, a 2 layer seal, and a thick rubber gasket, ensuring complete waterproofing. Well done Soundcore.
In this first photo, is the back half of the Rave Neo. you can see the amplifier board, behind the plastic grid you can see the monstrous passive radiator on the rear of the speaker which is what allows the speaker to produce powerful and deep bass. Below the amp board, you can see the big battery pack.
This second photo shows the front half of the rave neo, where you can see the big, beefy 4 inch woofer and 2 inch tweeter, wired up to the crossover I added myself, which is the circuit board with that bright yellow capacitor. You can also see the back side of the party lights panel.
This is a more side view of the front half of the speaker.
and finally, a closer look at the circuit board, and behind it the battery pack protected by a plastic shell.
