If you cannot figure out why your brand-new speakers do not sound as good as they did in the store, it may be the room acoustics. The Fulode equalizer is a marvelous little gem for correcting that issue. I purchased the non-computer-controlled version for $138 in June 2025. I placed a calibrated microphone at my seating position while using the free software, REW, to adjust my speaker and room acoustics such that the frequency response at that location was flat. Why flat? You want it flat to reproduce sound to match what the artist intended while in the studio. If you want to change or “color” the sound as done using typical bass and treble controls, you can, but with much finer control. In fact, you are the sculptor of your own sound. You have complete control with 31 bands of adjustment. I have included a picture of my room’s frequency response with and without equalization. Without equalization, the sound was “thin” in that it lacked low end including vocals along with a brassy high end. This is seen by a 25 db difference between 300 Hz and 1.6 kHz. With the correction in place, the whole frequency range is within +/- 3dB. This is what one would expect from a $3000 to $5000/pair of speakers. This correction took my homemade speakers to the stratosphere with regards to audio fidelity. The sound is beefy down low, provides vocals up front where they are supposed to be, and exhibits clear articulation between instruments. Your mileage may vary since not all speakers and/or rooms are fixable with equalization. Since I was testing this unit with a Fosi class D amp with no sub out, I found the sub out on the equalizer to be a welcome addition. My only complaint is that the sub output is limited to a type XLR. The mains have both ¼” TS and RCA outputs. I needed an XLR gender changer and an XLR to RCA cable to connect to my subwoofer. The unit plays MP3s off a thumb drive with no issues, and it had no problem finding my android phone using Bluetooth. All in all, this unit is a great buy. I plan on getting another and bi-amping my speakers eliminating the need for expensive crossover parts.

This is a good eq. Did not try the software, but the on unit controls are easy enough. Realistically in most scenarios once you have your settings saved, you'll probably be switching between your saved presets. Again, works well, looks good.

Nothing worked..directions for settings are terrible, nothing works/responds as stated, operating instructions very limited and don't actually work..item returned

The 31-band equalizer gives crystal-clear sound, with customizable frequency adjustments for deep bass and clear highs. The own seeting of 10 preset modes make it easy to switch and the Bluetooth 5.2 connectivity lets me control it seamlessly from my phone app. The LED spectrum display is a fun touch, visually syncing with the music, and the setup is quick and straightforward. Overall, it’s a fantastic addition to any home audio system!

I am an Engineer ,and I found the instructions confusing and incomplete. I am using this unit in my Home Theater as a low pass filter to tune 2 Subwoofers , I loaded the Software in my Laptop , makes adjusting very easy. over all I am giving high marks in performance.

Seems to work well and adds some Razz A ma Tazz to your system. Easy to use and program. Very bright LED's.

1) The software included on the USB drive is PC only; a .exe file. Hello, Mac OS? That's a pretty big miss. 2) The one knob used to manually control the settings seems to have a mind of its own. Very difficult to set the settings for each frequency because it keeps jumping around on you, so takes a while for each frequency to properly check and adjust the settings. The actual processing seems good so far. It'll take more time to really evaluate it properly.

I think it's great. Sometimes I just like watching it. It's nice you can bypass the equalizer by just pushing the bypass button . It took me awhile to figure out how to program it . The instructions are sort of confusing. I haven't tried the usb port yet , I'm working up the nerve to try it . It sounds great ,it's a real-time vu meter. I'm very happy with it
