"the dragon 12s are closer to REL 8/12 subs. ... No soundbar has anything close to this sub available. ... The 12s alone make this system untouchable by any other home theater in a box. No comparison!! ... Couple the 12”subs into the experience, you’re not getting that experience short of Svs sub territory. ... It’s a house shaking, chest thumping experience that is not able to be reproduced by any other soundbar or home theater in a box. ... Adding the two 12s to the 8s really has taken the system to the next level. ... The house literally shakes now with honest chest thumping levels. ... BTW, the 12s are RELs! ... The 90 lbs behemoths in the room! ... The chuffing from the 8s many reviewers have noted is gone when used with the 12s."


"nothing trust me nothing will literally hit u that hard not even Canelo Alvarez"


"IER not having absolutely incredible bass is objectively BS. ... The bass reading on the IER is so off what you'll actually hear if you have them inserted properly, it's absolutely ridiculous. ... I have Fatfreq Maestro SE CIEM'D which are their heaviest hitting premium model - CIEM-ing it only make the bass hit much harder, and it's still not quite as heavy as the IER."

"it has amazing clarity in the voices and instruments"


"ever since adding the Bar 9, the SA-RS5’s have become more present when watching movies. ... With both soundbars I always set to rears to MAX volume, but now I can actually hear them while using the Bar 9. ... They’re powerful at MAX volume and their sound is clean. ... The other night I watched A Quiet Place Part II. Rears were set to MAX but system volume was set to 30. I could still hear the rears loud and clear. This is with the Bar 9 in the system. When using the A7000, there’s no way at 30% system volume that I’d be able to hear the rears. ... the RS5’s are amazing now."

"The Ult Field 1 is definetly the loudest here by a ~1db difference wich is about 17% more volume than the Flip 6 so it will probably be the better option considering all of them are S size (very small) speakers and you want to fill a mid size room."


"the bass at loud volumes isn't as punchy as the ult field one ... the ult field one does loudness alot better"

"the rock songs specially the guitar ones doesn't sound pleasent... ... Sorry I mean Sony....Ult1 sounds unpleasant for some rock or metal songs.....I'm still trying to find a perfect balance for Sony...especially the guitar doesn't sound good in Sony ...

"The Sony has a veil in the mids that is impossible to EQ out. ... The only comment I can make about the EQ is that you can't get rid of the veiled mids. ... Yes it's loud and bassy, but the clarity is lacking. ... I returned mine because of it."


"You're not wrong, the equalizer sucks on the ULT Field 1 ... it is hard to get a clearer sound without killing the bass punch ... the best setting for that matter that i found is Bass +5, Mids +7, Highs +10, but it still not that great ... you can't have the ULT Mode enabled with your own equalizer, it's one or another."

"Unbearably peaky"


"The PR2 issue was interesting. First run had an additional filter between the driver housing and nozzle, which tamed the treble a bit and gave the tuning a more well-balanced and natural timbre. It was a $30 planar with an excellent tuning that was easy to recommend to new hobbyists. Blew up because HBB got behind it. Started selling like hotcakes. KZ decided to pull out the filter, wither to save costs, labor, or both. Totally changed the tuning. It was shrill, sibilant, and a tinny, metallic mess. They pulled the rug out to save a few bucks, and then reframed the change as a “retune.” It was a whole thing."

"equalizer but it is very bad tuned so it doesn't really work much ... bass slider also affects the warmth of the voices wich is something that shouldn't happen ... if you put the bass on +10, the voices sound muddy and it doesn't even reach the bass level of the Ult Mode ... if you put the bass on +5, mids on +7, and treble on +10 for example, to fix the problem of the Ult Mode, then you lose all of the bass and power that the speaker is intended to have."

r/Bluetooth_SpeakersLoud enough speaker to use inside shower
12 months ago

Well, considering decibel, 60 db at 1m distance is really quiet for what I consider a usable speaker. If measured the same way. I think most portables I know are in the range of a maximum of 83-90. This is cause 10db jump equals roundabout a doubling of the felt loudness. So 10 more is much (so, ~20db more at ~80 is waay louder) Are you planning to have your speaker outside of the shower? And a bit far away? Cause I would even consider my phone to be loud enough to use while lying next to my shower, so I would say get a good small one like soundcore select 4 go, that’s noticeably louder and thumpier than my phone, can be tweaked over the in app eq to your liking and is waterresitant so it could be placed next to you in the shower. If that’s not enough, i would choose a speaker with a 2-way setting (mid-woofer + tweeter) for more highs like the Sony ult field 1 oder Jbl flip 6. if it’s just for podcasts, I wouldnt go bigger than that cause i guess that mostly means just more bass, which might even be contraproductive since it might make it harder to understand vocals / speech.

r/Bluetooth_SpeakersLooking For a Speaker with Excellent Sound Quality and Good Bass and Battery Life

What do you mean with portability? Able to transport it with a car? Able to place it with other stuff in a bagpack? Able to carry it on a cart like a fridge? Also depends on where you’d use it and how you’d use it. Obviously, those portable ones (to just fit with your stuff in the backpack), you won’t get dance floor thundering bass and rather a good background sound for a gathering with a few friends. If it’s for the backpack style (cause that’s what I’d consider portable) I wouldn’t go bigger than Jbl charge 6 size. Different brands have different signature sounds. I really like jbls, and the newer Sonys. Pretty much any soundcore speaker and Tribit and so on that I had in my hand, I wanted to tune them over their equalizer cause I didn’t like there profiles (I remember them as muffled) Sony field 1 is a great portable and sounds good. Same for flip 7 and charge 6. also worth looking at features other than sound and robustness. Soundcore motion 300 also one I remember with a really nice sound. From what I heard, if you go for a Jbl charge size speaker, looking at the difference to the next bigger one like Jbl xtreme or soundcore boom size, I would say the sound difference can be named almost irrelevant. There is more bass, yes, but not enough worth mentioning to me. So I’d say go either flip / charge size for spontaneously taking to shower and back, outdoors in your backpack, or Jbl boombox size if it has to be taken sometimes by car and needs a big bass for a lil dance round.

The JBL Flip 7 and Sony ULT Field 1 both sell for less than $130, are water-resistant, and feature chunky rubber bumpers around their passive radiators to help with accidental drops. Bose says the SoundLink Flex is also rated as "drop proof", but it doesn't quite have the same amount of physical protection as the other two.

The JBL Clip 4 has a long battery life, for personal use (backpack, room, office) is surprising. The sonu ult field 1, withstands impact, good material and listening very well, a little larger than the clip 4 but it can be transported, I can recommend those to you since I have both and I assure you that they have good quality materials. I've had the clip for 5 years and it sounds the same as the first day of purchase.

As someone that's owned and returned almost all of these, my current favorites are the Sony ULT Field 1 and the bose soundlink max

Sony’s last wave of portable speakers were not great so I think a lot of people didn’t bother trying the new ones. For context, I prefer not having to mess with EQ to find the best sound, but I will do it to see if there’s any improvement over the default or the included extra bass mode (xbass, ult, etc). Speakers used to need to be EQ’d but the newest ones sound great without needing to mess around (for my ears). For portable, the sony ult field 1 is my sweet spot for sound quality and size. I used to carry around the bose soundlink flex, but it lays flat or on the side while this one can stand straight up, taking much less space. The passive radiators give it a ton of bass and I honestly prefer the sound over the flex. The tribit micro is “smaller” but takes up more space when using. The tribit stormbox 2 is a good budget option. Boom 4 was not worth the price. For home, the partyboxs are great but so big, also too big are the boombox, blast, motion boom plus, etc. The bose soundlink max is big but still pretty small in comparison and it sounds massive. Really easy to take room to room. The speakers that I am looking at that might replace it are the brane x, or the sony ht-ax7 for portable surround. Will be checking out the tribit lava soon.

r/Bluetooth_SpeakersBest portable Bluetooth speaker to Buy?
4 months ago

I think you would best like the Sony Ult Field 1 and with 2 units so around $280 if you get no deal...! So many choices many are great options though consider $65 the most to pay for a pair $25 TO 35 Each and some may need a .1 channel speaker as well I suppose JBL party mode is supposed to be most flexible but I hear my Ult Field can work with more than 2 speakers if they are all Sony please consider the big ULT field offerings also perhaps one ULT 7 center 3 ULT 1 surround

It is very good try just using the onboard Sony sound in place of poweramp EQ though preamp can go high and never do you see the distortion usually noticed by us and we overlap units +7+7 +6 is too high! Lastly my demux profiles have a notch 188 Hz sharp Q down 12 dB : Tweety needs to be T 225-15000 Hz Woofie is at 12-145 and Thumpers 0-100 hz You can see a missed coverage 165-300 but listen to various "demuxing" notches of your own designs see the difference.... The the Ult Field is the easiest to use speaker so far by a long way I also have owned Beats products very similar to my Radio-Shack clock-radio format speakers I originally used with my REI accelerator Panel...remember in Series OR In PARALLEL your decision but + is - and - is + that's not your choice!

I got a pair of them too! I got mine on sale too but I still paid almost double of what you paid. I wish they had an aux port though. Might end up buying the ULT 7 just so I can use it for movies.

r/Bluetooth_SpeakersHad a chance to check out the new Soundcore Boom 3i
7 months ago

I tend to purchase smaller sized speakers like the flip, ult field 1, and I purchased the boom 3i to replace my ult field one and the 2 things I dont like about the boom 3i is the bass at loud volumes isn't as punchy as the ult field one, and id go as far to say the ult field one does loudness alot better, which sucks becuase this speaker is advertised at 50w and the ult 1 is 30w. secondly, the battery life is mediocre, but its understandable becuase it maintains a nice deep bass at low to medium volume. So if you regularly play louder music probably go with the ult field one since its about the same size, and if you're going to listen to low to medium volume music, then the boom 3i is perfect.

I bought three ULT Field 1’s and one ULT Field 5 at Target while they were 70% off (in-store). The ULT Field 1’s are very portable. They are very nice. They sound relatively close to as quality (I’d say about 75% as good) as the ULT Field 5. I am going to Keep the 5 for myself and give the 1’s to my family for Christmas. I think you will like the 1 if you choose it. I am mostly just using it for inside my house and that is why I opted for the 5 for myself. If I needed something super portable for on the go, I would have kept the 1.
