Swissonic A305

Well pretty useless to stuff the ports because you use a subwoofer and then dont use the subwoofer.

You need to Look at the complete system then.

You made me worry then laugh with that first sentence. I will also measure the sub separately I think before measuring full. I am using rew and measurement mic for the first time so it is kinda fun.

That 80-120Hz suckout/dip is your room or the speakers or placement (i wonder) ?

Seems persistent with bass port stuffed or not, though in previous measurements it wasnt there.

It’s not the speakers - the first measurements were are all C between two pointing straight forward speakers, this time I took them left to right but the speakers are extremely toed in to the point that facing the R speaker means you are on axis with the L.

I think it’s ceiling/corner relating, as the dips moved more front to back.

I think my panels might be better suited positioned as if my speakers were torches. Rather than using the mirror method.

It sure is and you learn a lot from it. Just trying to help a bit

If I wasn’t so lazy I’d set my Yamahas back up to try and figure out why they sounded better with no toe in. I’d probably realise it is my head needing toed in

You are more than helping btw, as is normal in this place.

Maybe this explains my new preference for extreme toe in (or not). These would be at about 45 degree to on axis, but with on axis at furthest distance. I had recalibrate for my 3rd MLP (l) measurement but they are very close.

So do you like how they sound or not?

Yes I do, whatever little that is worth. I am still slowly setting them up but I'd bet my next measurements will have much better ETC within the first few ms after source as I have moved around panels to take care of the new toe-in and used them a bit more efficiently. Stereo is now fabulous and feel like I can hear the speakers directly.

Perhaps I am so fond of REW I think it can hear everything, but I am hoping this is far lower and more symetrical with next measurements.

I was focusing too much on frequency response before and boring everyone with pointless graphs. Rest assured my next graphs will be just as boring, but more focused on clean early response.

 

[Basic Channel]

So as promised, I am going to be boring. I am maybe reading too much into ETC, but it seems to show exactly what I am hearing, and the improved measurements are as I predicted and expected. A lot of frequency stuff is interesting, but barely audible to me by comparison.

Long live the REW and the fibreglass panel.

Before and after, L speaker reading at C position. The left speaker was the bigger offender

And the R speaker at C position before and after

To be fair, the new average looks better too but really I think it doesn't mean too much. If future averages look worse I will keep this so I can say I am within 4db above 200hz. Yellow line is a windowed response for no real good reason really.

I just got the A305 and got TERRIBLE ground loop sounds when connected to onboard sound via 3,5mm to RCA.

Its the most terrible ground loop Ive ever heard, like 50db squeaking and hum - i can even hear mouse movements through the speakers. Any possible solution without buying (which i wont) a balanced DAC ?

EDIT: man this is terrible, this is pretty much totally unusable - never had such a fucked up product.

You could try a sheath current filter/ground isolator.
At one point in the past I used a Monacor FGA40HQ (about 20€) to get rid of a ground loop and it worked, but did cost some volume. Got a DAC afterwards and it felt like a significant upgrade (had a cheap 400€ tower pc).

Do you have any issues with an other device like a phone?

The onboard sound is sometimes very bad and it is worth to replace it.

There is the option of a transformer device but i wouldn't go that path since they are either expensive or didn't measure and sound well. A inexpensive sound card most of the time works as well and is cheaper.

I resolved with an ac plug without the earth pin connection

 

[ninetylol]

Well for me this product is DOA, I really dont wanna play with Power cables. Even tried a floating preamp between, same problem.

The Super cheap Edifier Mr4 had no problems whatsoever, so its not a source problem.

I can understand your frustration most likely any monitor with a ground connection will provide the ground loop and the noise. You have to have a look for active monitors without a ground connector than.

You can do that but honestly I wouldn't do it. If the electronic has a severe malfunction and you don't have the grounding it is seriously dangerous.

Trying using a different wall socket for your monitors with an extension cable away from your PC's.

Trying using a different wall socket for your monitors with an extension cable away from your PC's.

I bought a big (10 socket) extension and intended to put everything on it (not got round to it yet). Are you suggesting to put all the speakers separate to everything else? I'd say my sub/TV are the issue. Should they be separate on separate plugs from each other?

I have 2 mains plugs (on different side of the room) so have no option but to use extension cables (if that is an issue).

Whenever i tried using any monitors connected my pc/soundcard(s), when they sharded/used the same socket there was always loud noise coming from the monitors/speakers, when i used an power cable extension from a different wall socket the noise went away in my case.

Thanks but I already sent mine back. I Was so pissed off about them, I couldnt have taken any joy out of them.

Yeah, that's pretty normal. Buy a balanced DAC. That's the solution.

Hardly fault of the monitors, basicly expected behaviour on such a setup. Keep that in mind when getting next monitors.

No problems with Edifier MR4, so engineering Problem of the swissonics.
