Motion Boom custom EQ for better clarity and open sound question

I played it at 100% volume few hours in garden. Seems alright. Everything is working.

But that just me.
You are not overclocking anything just using app provided my Soundcore.

try +5 +4 +2 +4 +6 +4 +3 +4 +2

EQ is a tricky thing. Everyone hears differently, listens to different types of music. Even within the same genre, it can be mastered differently. Add to that depending on placement, the sound will change. That’s a long-winded way of saying that I don’t believe a perfect EQ for everyone and all situations exists.

This is where I am currently. Since “more clarity” is the topic of this thread, I thought I’d share. Remember, this is with my Motion Boom in the corner of a bedroom, sitting on top of my bed:

Response still drops after peaking above 13 KHz, just as it did previously. The Samsung A54 that I’m now using comes with a “Dolby Atmos” app, and I leave it on “Auto”, as any of the other presets screw up the frequency response too much and make anything I’m listening to sound worse. With the Auto setting enabled, there’s a slight increase of ambience and stereo effect sometimes that actually helps the Motion Boom’s lack of stereo presence without drastically affecting the frequency response too much. There’s also a slight increase of volume with it enabled, so I usually leave it on. When EQing, I ran manual sweeps and compared with the Auto setting and Off. Frequency response deviations between the two weren’t enough to warrant any EQ alterations.

I still suspect some slight peakiness in the top octave with my current EQ setting, but I’m leaving it for now. There are several dips and peaks that can’t be improved with the provided software, like an obvious dip between 6 to 7.5 KHz that I really wish I could alleviate. Not surprisingly, harmonic distortion performance seems quite low as well, especially in the lower frequencies, but that’s to be expected. Still, my Motion Boom probably sounds better right now than it ever has.

That said, these units are still lacking, and I still want to improve the sound with some minor and simple modifications. The resonances I mentioned in my previous post still bug me to no end, as I often hear them quite easily during music listening, even at modest levels. On top of eliminating these severe vibrations, I still want to experiment with stuffing the enclosure with various amounts of Polyfill to improve the “bass” and lower midrange response.

That’s it for now. I’ll update if I ever crack mine open and try the aforementioned modifications. Happy listening!

Edit: I also want to mention the possibility of a significant boost centered around 50 Hz (digitally or electronically) that is particularly noticeable at full volume. While this doesn’t lead to an actual peak in the resulting frequency response, it does significantly increase the likelihood of blown speakers! I’m sure they’re doing this to increase low frequency response, as most 2 to 3 inch drivers typically begin to fall off well above 100 Hz. So, the low frequencies are already boosted very heavily from the factory (too much, in my opinion), even with the 80 Hz slider at 0 dB. Be careful with frequent 50 Hz bass notes at or near maximum volume levels! I’m saying this as a result of my own experience (I nearly blew my Motion Boom’s speakers one day with the frequency generator!). If you play a 50 Hz sinewave recorded at 0 dB at maximum volume, your speakers will likely be toast after a few seconds, even with the 80 Hz band lowered. Just passing along what I’ve learned. Take care…

Try these settings for motion boom +…you will be thankful to me 80Hz+5db, 150hz+2db, 300hz+0db, 600hz+2db, 1.2khz+0db, 2.5khz+2db, 5khz+4db, 9khz+6db, 13khz+4db.

Thanks to the previous user who pointed out the frequency responce graph, very useful.
Here is my initial interpretation that sounds great in my kitchen.
+0,+3,-2,-2,+1,+2,+6,+5,+0
