The King Kong of speakers
I was shocked when this arrived because it was a lot larger than I had imagined it would be. I had to use my dolly to get the box into my house. I had to remove the shipping box away from the product box and then I slid that box across my hallway floor into my bedroom where I unpackaged it.I’m not sure how much it weighs but it is very heavy and way more than I should pick up because of my back injuries. Shouldn’t be a problem for able bodied individuals though.The design of the Bluetooth speaker is modern with an ergonomic handle as well as a shoulder strap that can be used to help carry the speaker over long distances.This is waterproof so it is safe to have it around pools, the ocean, in a sudden rainstorm etc it’s got you covered, indoors or out doors, for parties or or personal entertainment.It has lights that are on each end at the speakers as well as on the lower front panel.It has the following ports – USB, TF, C, auxiliary, Wi-Fi, Bluetooth. It can sync to other speakers with a push of a button.It paired with my fire TV very easily I wish I could say the same about my echo. I’m not sure if it is compatible for Alexa electronics but it could not find the speaker and wants me to download the app for the speaker. When I looked for the app for this speaker I found there other products apps so I’m not quite sure where or if this one has an app.What I am doing now is whether I turn my TV on first or the speaker on first it doesn’t matter after they’re both on I just tell Alexa to play the music and she complies taking me to my favorite tunes. (Funny thing right now as I was speaking the aforementioned scenario Alexa heard me and then told me that it was offline, LOL just thought that was funny)It’s got the tweeters and the woofers and The equalizer I have to admit I’ve never really been into all that stuff worried about it if it sounded good it was fine for me. But it sounds good and has a lot of neat functions. And works great with my TVs.

This is a big boombox, really big.
First off, I was a bit surprised at the size of this thing. I’ve linclided a picture with a can of pop. It has a massive battery and also weighs more than you would expect. Jas lights on the bottom front and around the passive radiators on the side. 3 EQ modes to pick from, bit Zealot still doesn’t offer an app for their speakers, which should be a given considering it’s 2925 and they have a bunch of speakers on the market.The default EQ seems to be the most balanced and the one I prefer. The bass EQ is way too muddy, bloated and dark sounding. The bass output is very solid, although perhaps a bit less than expected considering how large this speaker is. This would be on a short list of large Boombox speakers to check out. Just know what you are getting, because this is a big one.

Big, speaker, kinda Odd carrying it
This is a beefy speaker big in size and carries some weight along with it.It’s a little odd carrying it because of its awkward size and weight.. It’s beefy, bulky And sound quality is very good however I felt for being this sheer size It could have been a bit deeper on the bass… Even when you activate the bass feature, The bass sounds good because the mids & the highs been brought down So it helps you hear the bass a little bit more.. It’s loud I had a few things that I wish could be better. Deeper bass being one of those areas. The other thing I kind of found odd was that if this speaker is just standing up right on a table or flat surface, I’m not sure the dispersion rate of the speakers but they seem to be a bit downfiring as far as the dispersion because if you stand in front of the speaker the dispersion rate doesn’t seem to be as high firing, meaning the sound dispersing up, It seems to disperse more downwards. So I’m wondering if maybe they could change the tweeters down the road to disperse a little bit more higher meaning upwards versus downwards. Or possibly change the location where the tweeters are at so they’re a little bit higher so they cover more height rather than dispersing more lower.. I felt that it could have gone a little bit higher and sheer volume. So I downloaded an EQ app and adjusted the frequencies and the volume and that’s where I noticed the huge gains that the speaker has a lot more it can output And it sounded louder and better vs without any app. Right out of the box I feel it’s lacking just a little bit and downloading an equilization app would help one find tweak this year volume frequencies tone and bass levels… Inside the house It’s as if the sound was bouncing off the walls and didn’t sound that good. So I took it outside in my backyard and I noticed that’s where the speaker seem to shine the best for me and it also sounded good when placed on a chair and slightly tilted back to throw the sound up a little bit higher… Doing those few things for me really made this speaker shine so much and made it that much more louder. It’s not a bad speaker at all Just using it as it is but I would recommend downloading an equalization app and find tweaking it and tuning it to your specification and liking and it would also add to the sheer volume of the speaker.. So it has its pros and cons and those can vary depending on person and on usage and place, like indoor outdoor… I’m glad I was able to play around with the speaker and for me make it sound that much more better. This is not the kind of speaker that you’re going to be walking around the park with on your shoulder. This is the kind of speaker you going to want to place in a location and leave it there and not walk around with it It’s kind of heavy and bulky. But it does pack a punch.It just dawned on me, you could put this speaker on a speaker stand & it really shines there…

Just what I was looking for.
I gotta say… This thing KICKS!I’ve had mine for a couple of weeks, ran it at (probably) 75% volume and it was still at 100% battery life.Bass is as good as you’re gonna get out of a device like this. It isn’t small, or light tho (you need hefty magnets in order to produce the throw of the diaphragms on the Woofers).The tri-amped system delivers clean and clear sound from top to bottom (and the tweets are well tuned- no shrill, painful high-end).I may purchase another in the near future.I’m not affiliated with the make/seller of this thing but, I’m giddy over it’s performance.
