Where are good places online to buy components with which I can build amplifiers and stuff like that from scratch?

Thanks

I have a work laptop but it’s restricted.

Hai I have recently brought a audio amplifier with common ground for stereo input ,and I have a Bluetooth audio reciever have a seprate ground for both channel how should I connect this ground with audio amplifier

Hey everyone,

I just picked up my first kit (Overnight Sensations!) and I'm wondering what the options are for finishing the enclosures. My woodworking skills are quite lackluster and unfortunately I don't have access to my random-orbit sander so I'll just be working with regular sandpaper. My previous project was building a pair of perf-stator ESLs which I basically primed and then spray painted the frame and sub-box. And while it turned out okay (coating was uneven), I'd like to take it up a notch and do a gloss finish (I recognize that the picture isn't a gloss finish but that is the colorway I'd like to do) if that's possible for someone who's relatively unexperienced with painting/finishing. Is there anything I should be aware of and how do you recommend going about it? If that isn't suitable, are veneers/wood stains another good avenue? Thanks in advance!

Hi all, I'm working on a cabinet build and I will be recessing the drivers to mount flush to the front baffle. I am curious how much tolerance you all allow in terms of a gap between the edge of the recess and the driver. Here's a couple of pictures from my test run this morning and I am not really happy with the accuracy (gaps) and I am wondering if I'm being too picky https://imgur.com/a/iiqPyjN

I do plan on painting the baffles black so the gaps will mostly not be seen and I think I can tighten up the tolerances slightly on my actual build. Just curious how tight you all try to get these.

For reference I am using the Milescraft circle cutting jig and a router. I'm not overly impressed with it's accuracy but mostly I'm still developing my woodworking skills as well.

Thanks,

Hi guys, another question here, would be great if you could help. We recently moved to a house with outdoor speakers.. Do you have any recommendations on very basic amp that does its job and bluetooth function? The wires for these speakers connect into a cupboard into our kitchen, which is not a great location, so we might need two different amp in the same area. As I also want some speakers for the kitchen/dining area too.

Kind regards, Cecilia

Hi guys, years ago, I came to this Reddit for help to set up my little audio system, thanks for everyone's input, I've been really enjoying the audio setup that was recommended by many Redditors. The Wharfedale Diamond 9.1 Speakers and a very basic amp have been working really well, I matched them with a turntable, and sometimes I switched the amp to connect with the TV.

Now, after 4 years, I would need help again please!

Firstly, in the living room, we want to change the amp as we want to be able to connect to TV and the turntable without changing the wires/cables. (I have been doing this manually, which is not too bad but not very convenient)

Additionally, we also want to use the turntable in the dining/kitchen area sometime too, as this is where we hang out most. But at the moment, in this area we have no audio system at all. So I need to get a pair of speakers and an amp too. I plan to get the same pair of speakers, but the question is how to position them, should I put them on the corner ceiling, or should I buy speaker stands like this one below? But how do I do about all the wires etc?? Would be nice if we could also connect to the speaker via bluetooth, so maybe am amp that has bluetooth function?

Sorry for some dummy questions here, as I am still a dummy in audio! Would really appreciate any of your inputs and recommendation!

In short, any recommendations on very reasonably priced amp that can connect to both TV/turntable and have bluetooth function, and how to position the speakers?

Many thanks!!

Cecilia

I build an active Speaker 2.1 system with various parts pieced together. The Input Signal gets processed with one DSP (adau1701) per Channel and gets amplified by 2 separate amplifier boards. One for the two way sattelites ( 4ch amplifier for stereo and Low/ high signal) and the stereo Subwoofer Signal gets wired Back together Into a mono Signal. This Signal is amplified by the AMP in the picture.

The Problem: The Subwoofer Sometimes begins to output an irregular noise Like in a ground Loop. But not all the time. It even went away for a Long Time after I got rid of an (in retrospektive rather superfluous) dc-dc isolating Konverter wich let me to believe that i fixed the issue. But now it came back an I have No clue anymore on how to fix it. The noise goes away when i dissconnect the Input Signal (Just hot wire does it) and stays gone for a short while when I reconnect. I believe to have noticed the Problem comes Back when i dis/reconnect the Subwoofer speaker wires, but that would`nt make any Sense. I think i remember it even appeared when i had no Signal wire Connect at all.

Has anyone an Idea where this noise May come from? I would appreciate any Help deeply.

Hello fellow audio enthusiasts! I'm building a small-ish 2-channel sound system and looking for one final missing link.

Basically the only two things I need is a crossover, but with parametric eq's on both the paths of the crossover. I have no problem with soldering and making an enclosure, so ideally in the form of a board, no box required.

However, I just couldn't find anything cheap with those features, the ones I found were some expensive looking audiophile level boxes. There must be a circuit board option, right? Or should I instead look for a separate active crossover board and two param. eq boards? What would be my best choice here?

Thanks for all and any help or insight on this!

I have a transformer that I purchased a while back for a project. Lost the instructions that came with it and can't for the life remember how to hook it up. Particular in a 220-240V mains environment. On the transformer are two input points with 135V. Can anyone shed light on whether if it's compatible with 220V or do I need to use a down converter? Unit is supposed to be used witha Jadis JP200 preamp build that i completed halfway and planning to return to finish it. Thanks.

After my original post https://www.reddit.com/r/diyaudio/s/ZL9746T1i1 I took the advice to build the speakers first and take measurements, so I did. But the response is quite different from the factory response.

I modeled the XO but I'm not sure if it's all correct.

I took the measurements user REW with an IMM-6C mic placed level (the mic was pointed at the ceiling so to say) at listening position. Did I do something wrong here? Or is this the difference between factory and real life?

This is the schematic for the Swope 3 way towers. I’ve got all grounds soldered together in one. I’ve got a tweeter crackling now and I’m just curious if my creating a common ground between all of the drivers is a problem. Before I soldered it, I checked with other people on forums and they said that was fine. But how do you know if there’s a common ground or not? I did another project where I made the ground common between both drivers in a two way, and it was definitely causing a short. The amp kept shutting off. But as soon as I made separate grounds for each driver, that solved the issue.

Had a bit of slippage of the template on layer 2 of the internals but when the final glue up comes I’ll put some wood filler in the mask it.

Can someone link me to the products that I need to hook my new Behringer NX3000D to my AVR and my DIY subwoofers with binding posts? I purchased some products, but I am second guessing myself and want to compare to what this community suggests.

The NX3000D lists its inputs as 2 x XLR-1/4" combo and I will be connecting this to the RCA subwoofer out port on my AVR.

The NX3000D outputs are listed as 2 x SpeakON and they will be connecting to my standard binding post.

Cheers

The picture actually shows terminals for a pcb…I actually am looking for some for a regular DIY crossover. I must be searching using the wrong terminology because I can’t find didly squat. It doesn’t have to be quick connection but I would like to be able to unhook wires from my crossovers without having to cut them. TIA
