Im tasting for some time this small thing and one thing I've notice, small humming sound then its not reciving audio from audio source... I dont know how to fix this ?? Any ideas ?
Has anyone fooled around with Audio exciters.. ? Ive had outstanding success with isolated (free hanging) medium sized coroplast and heavyweight corrugated cardboards in smaller to med sized panels with 3 to 20 watt exciters (approx 21x35 ) But by far foam xps has given thr best results ... I have tried all thicknesses.. been using 1/2" xps insulation foam board (expanded polystyrene ) foamular 150 brand pink. 48 x 30 panels (almost3x5 ratio) , large radius corners radius starting 6" from the corners and smooth the edges all around.. heavy bead of pure silicone caulk applied to the edges and spread out with an old paintbrush made a durable edge and eliminates alot of detail sanding the imperfections from the cutting... Exciters applied at the 2/5ths over from one of the sides and 3/5 down from top (critical for proper range) .. then drill or burn 1 inch diameter holes through about 4 inches from each corner and roll eggcrate foam around hollow rubber tube and stuff through the holes .. seems to isolate the panels from the wire or string used to hang them from the ceiling, you may have a better idea that was within reach in the garage..hanging with a foot clearance each side... hanging in opposing corners at a 45 seems to allow sound to bounce off the corners behind the panels and gives the best stereo for my room setup... Exciters used have been hit and miss.. absolutely best for panels has been Dayton 40 watt 32mm mega bass with the 4 legs .. 30 and 40 watt metal support spring types are also very good.. The pair of panels with exciters using these type bluetooth boards will blow you away and change your mind about how good resonance panel speakers can be.. proper panel construction.. carefully isolating wires and panels..rounding edges etc is super critical for good sound.. as critical is placement of the exciter at 2/5th x 3/5th location... and the 3x5 ratio regarding the panels dimensions.. so keep your dimensions close to 18x30 inch (3x6 x 5x6) or 21x35 inch (3x7 x 5x7)...or 27x45 inch (3x9 x 5x9) or close as possible and round the corners radius edges and you'll be good to go.
it wouldn't make much difference. all that does is increase the DC filtering on the PCB, which if you have a good enough power supply, won't matter much.
its a full range amplifier you can use it on any speaker. loudness depends on how loud you speakers can get. the small bookshelf speaker i used here got fairly loud from this board. for subwoofer use you probably want to find a mono TPA3116d2 board. this one is stereo and wouldn't be ideal for such use.
Try to get your hands on a better scope. Appears your trying to be another JohnAudioTech type channel. It's all fine, just try to do it right. Watching a speaker being trashed with massive distortion is only entertaining to those not really interested in audio.
lol i actually watch JohnAudioTech, i was going to get a new scope for the longest time but in the last couple years i dont do as much electronic work as i used to so i dont see the investment worth it. Even tho i can get brand new digital scope from a good brand like Rigol for $259 and Siglent for $279
@@bassblasteraudiotech4918 I have multiple scopes and the prices I paid are way way more then what they cost these days. It's funny how everything else appears to have gone up in price but the scopes and some other test gear has plummeted. Perhaps it's because people were not in buildings using/buying them as much. Good luck with the channel.
Really ? 185° 120° ? what kind of childish measurement system is it? When will farenheit lovers grow up? Obviously, they only want to themselves. That's a real pity, be honnest.
I'm listening to this on a X-502 amplifier board and two 40W speakers.
Sounds great!
You can solder here the bluetooth module BK3254

the first good emplifire test on youtube
Ehhhh, theres lots of better ones out there. i just do the things other people wont do.

How to connect bluetooth module pls.
What will be the effect when I change the 35v1000mf capacitors with 35v2200mf capacitors. Kindly answer me.
Thank you.
it wouldn't make much difference. all that does is increase the DC filtering on the PCB, which if you have a good enough power supply, won't matter much.
Does it take a 16 awg wire, or something smaller?
I'm using 20 awg solid wire, and it works fine.
Thanks for your video project about our product. :D
Can you try 12v and 2A power supply ... i plan to buy one
it wont be any different just have less power output. 12V X 2A = 24W. so 24W going in, no more then 24W out.
Dear friend, what will be the effect when I change the 35v 1000mf capacitors with 35v 2200mf.? Kindly answer me.
Thank you.
nice work to my country this system cost 20euro i think
what power block?12volts?
my supply can go up to 21V. but the TPA3116 will work down to around 4V
