So, the sound on this is a tiny bit weird (especially if you fiddle too much with the treble), but overall, a very very very powerful sound, well rounded, and also very powerful.
I would genuinely recommend it but ... if you have to get up and turn it on every single time AAAANNNNDDDDD also adjust the volume to max EVERY SINGLE TIME ... yeah ... so, I'm only recommending this to people who want to have a play with the board inside ...

The Vappeby Gen 3 speaker addresses all these issues with battery for portable use and synchronised volume controls between paired speakers. A pair of these speakers sounds good enough for pretty much any domestic use.

@markpreston3406 4 года назад

Hey, thanks for this! I've been using one of these in my kitchen (wired to a cheap DAB radio) for a couple of years and been tempted on a few occasions to have the back off to see what makes it tick... Now i'm very firmly from an old school 'flat earth' analogue hifi background so the Eneby instantly appealed to me as it's a 'proper' wide baffle box'n'cones speaker with no frills (i've no use for network/app/smart stuff and only occasionally connect my phone via bluetooth) So, cons: - I don't mind the auto switch off but it'd great if it also woke up when a signal was detected. The Vol control isn't an issue to me as i use the vol on the radio, pre-amp style. - Auto switching between the jack input / bluetooth is a big miss, having to pull the jack out to connect a phone is definitely an oversight, though hardly a deal breaker! That's it... Pros: - For the money, It sounds *tremendous*, easily bettering many boxes i've heard at double or triple the price. Goes loud but clips out pretty benignly, nicely balanced, more than adequate timing, surprising bass heft AND control plus the rear port means you can 'tune' it via boundary proximity. If you're demoing it should be noted that the tweeter is a little ragged straight out the box but smooths out noticeably after a few days use... - The inclusion of tone controls, and i type this as a someone who usually considers them superfluous, is a real boon and something that many of these over bassy wireless speakers could use (I'm lookin' at you Bose) as well as being useful for clawing a little more life out of sub-par MP3 uploads... - To my eyes, it looks great, grille on or off. That's it, i'm hard pushed to think of a way of getting more sound for £80, this thing is one of the biggest bargains in home audio. I can only conclude that none of the hifi mags have reviewed it cos they don't want to piss off their advertisers... ;-)

@joaojoseluz 5 лет назад

The sound is amazing!!! I´ve heard Harman Kardon onyx 5, JBLs, Naim..., and truly, this one sounds really really nice and powerfull. Misses the battery...

@Darieee 5 лет назад

mmmm, will have to disagree on it sounding nice onyx (lost track which gen) was super bass heavy, to a ridiculous extent, so, yes, not good jbls are also imo too bass heavy compared with some krk monitors or something like an iPod hi fi set to bass boost (if you can find one somehow), it's no match the eneby, at least the first gen (who knows maybe they retuned it, it would literally take changing a few values in rom), was insanely lackluster in the mids mine sounded mega mega weird, I gave it off immediately for about 40€ or so

By the way the csra64110 appears to be cross-compatible with the beloved csra64215, so if you are up to desoldering this one and changing it to the 64215 you gain the features, and i think that (maybe) it is possible to copy its firmware, and so you can get aptx in the eneby.

@Darieee 5 лет назад

yeah, I strongly suspect they are pin-compatible ... and as far as I'm aware the eneby runs a rather stock firmware/psr on there ... might work to just swap em over ... buuut, yeah ...

@tuttocrafting 4 года назад

I've reverse engineering the whole PCB. IKEA just spent a lot of money for nothing. They are using the BT DAC than the external ADC to go back to digital... They could just have used the CSR module to do all. Aux input is a standard mix and buffer, the BT is a simple differential to single ended signal buffer configuration. Theya re using a Precision Rectifier like circuit to detect the analog signal for the standby function. (This could have been used for both BT and Analog Input but they did not do that) One of the four Opamp is not used. They could have used it to design a virtualg gound circuit instead of crating three different biasing circuit, and use tons of capacitors for nothing. Due to the higth complexity of thoose aplifier they could siply have used two tpa3316. Use a full analog circuit instead of going back and forth with analog and digital. How about the BT/AUX switch? they are usign a quite cool 4 channel chip. Useless in this application. They are only using half of it. They could just have used a simple 2:1 mux. They they have decided to use a ton of BJTs/Mosffet to drive power gates, they could simply have used the pins directly from the MCU... Also LEDs are drived by external transistors. ANd yes there are two leds with different functions. Next step for me is to dump the i2c communication and the power gate sequence... BTW why did they have not done things differently? I'm not an EE, but this is what I've would have done with the same components: Use the I2S output of the CSR module, Slave mode MCLK generated by external source. And use the ring buffer oscillator they already use. Directly connect the Aux to the ADC, at least power gate it for the ENEBY20. Drive the AMPs with the I2S signals. In this way its all Digital for BT,a nd the only things that should be converted is the AUX input. The cheaper options for them, would have been: Use the CSR input function forthe AUX, I2S directly to the AMPs Now, my last hack/ideal solution: Remove all the analog stuff, use a smart codec with stereo ADC like the CS4265, and two or more I2S interfaces to process the signal path. In this way we could also have SPDIF input! Anyway, hack into the i2s should be easy allt he signals have a 100Ohm resistor that divides the amp section and the ADC.

@Darieee 4 года назад

thanks for the detailed breakdown! indeed - this speaker seems to all intents and purposes to be a school project

@tuttocrafting 4 года назад

@@Darieee I'm preparing the full schematics :D This weekend I'll publish something on Hackaday. The importatnt thing is that it sound good. I want to mod it to add TWS, and if possible add SPDIF or a RPI for music streaming. (I know that there is the SONOS speaker, but that one don't have BT! And Sonos is having some issues on comply wiht UPNP standards...) Have you avere played with the CSR SPIDF/I2S interface? I'm waiting for the SPI adapter to hack it. I would like to know if is possible to route an analog signal via the built in ADC to the slave BT speaker! I2C Protocol DUMP done! Looks like that they are mainly using the default register configuration. But decondig the 20byte EQ registers is quite a mess.

@klausagnoletti1027 4 года назад

@@tuttocrafting Did you ever publish your ideas to Hackaday? I wasn't able to find it and after researching I so much agree with your view. IKEA could have done so much better. I found out that at least the csra64115 natively supports seamless switch BT and AUX. So instead of doing whatever crap they did where it's either or, they could have used this. And I would have loved that. So I am definately up to some heavy Eneby modding. Unfortunately I need help from someone who actually knows what they're doing. So I would really love to get your input here :)

@tuttocrafting 4 года назад

@@klausagnoletti1027 at the end I didn't push anything due to the fact that other than the mcu the other stuff is a straight configuration from the datasheet. If I remember correctly the adc clock come from an not gate oscillator. And the downmix is done on the analog section near the analog mux ic. I'll try to see if I have the paperwork of the reverse engineering work I did. About your question, the car chip have aux in, but the adc in that one is worse than the on supplied by ikea. If you want to mod it what I would do is: Bypass the analog mux, find a way to downmix stereo to mono in the csr chip. Then use the mux switch select pin to switch the i2s digital signals. The csr must be set as an i2s slave with master clock from the original adc clock source.

@mariushmedias 5 лет назад

The voltage they chose to go with makes me think they have considered releasing a model with built in battery in the future.. 18.3v is in the ballpark of laptop chargers and lithium batteries that have 4 li-ion cells in series ( 4 x 3.7v..4.2v = ~ 16v) so just the right voltage to charge such batteries. Otherwise... is there enough room for a lead acid 7Ah battery like the unes used in cheap UPSes ? The whole thing is heavy anyway so if you're thinking semi-portable, like taking it in your car to a picnic or something (so you don't have to carry it in your hands for long distances) then a lead acid battery may make sense.

@Darieee 5 лет назад

hmm, nah .. I don't think is has anything to do with it ... it's a nice voltage to be at ... but everything will run on 9v as well ... I'm actually working on a 3S pack now wich will reach 12.6v at most I don't think a lead acid would make much sense ... and you'd have to stick it somewhere in the upper part ... which would mean somehow extremely safely securing it ... it would also make the entire speaker top heavy ... and at the first topple the lead acid would become loose ... yeh nah ... sounds rather nightmarish

@Darieee 3 года назад

you should attempt to change the power supply - get something with a similar voltage and feed it into the amplifier board you MIGHT get away with using a laptop power supply - those are 19v do check - I think the original was 17v if that's the case - 19 should be fine

@AlexCailliau 5 лет назад

Thanks for the teardown! From what you say it should run without any problem I’m 12v. I’m not thinking battery, but I’m considering the little brother (eneby20) as a Bluetooth speaker for a camper. The 20 is just easier to fit in a tiny space, should have enough power and is syncing the volume ;)

@dorjedriftwood2731 6 лет назад

I can’t understand why you would want a receiver to adjust itself relative to phone volume. As I understand things you usually want to adjust volume on the speaker primarily to reduce distortion which will increase the lower your output volume. If I have the option I would never want my output volume to be lowered at all, I would always prefer to adjust volume on the speaker. I may leave myself some room on the phone. Volume on a device I would set relative to the device. Generally in my experience speakers run too loud at full volume and usually hum at full. It doesn’t seem preferable at all to sync input and output. Even if Bluetooth doesn’t ruin the signal by changing the waveform it’s still preferable to be able to set the relative volume for the setting the speakers in. Like you said you’re walls are thin so you wouldn’t want to accidentally blast the speakers because your phone was at full volume. I think I must misunderstand or simply have a different philosophy when it comes to audio.

@Darieee 6 лет назад

There's no distortion based on volume on the modern digital amps (they're almost always at their specified gain, though these might not). You would want there to be a SINGLE volume ... the phone is at 50%, that is 50% on the speaker, you increase the volume on the speaker, it shows on the phone - the Bluetooth is sending instructions, not an analog sound - so ... distortion can't play any role in this I'm sure you wouldn't prefer having to adjust the volume on your speaker after EVERY time it turns itself off, when the alternative is never having to do that with no penalty in quality Again, with the hum at full volume - not the case here - and I want a unified volume, so, there would be this hum only when playing a silent track on the phone AT FULL VOLUME Yeah so, regarding the rest of the comment - the above mentioned should have been enough to cover the last point you've made

@Wibinable 5 лет назад

On digital amps it doesn't matter if it's the built in wheel or bluetooth volume (=phone volume) that adjusts the volume. If it comes via bluetooth, you have the full volume range available. If the control wheel is separate, both the wheel and the bluetooth output needs to be set to full to get full output. Cheers!
