Adam A7X: Buzzing and rattling around 100-150Hz

[blueman]

i don't think your taking this to 'the next level' when you should be.

I've thought of that. For my own peace of mind, I need to go through certain steps before it elevates to that point. I'm not at all afraid to go the distance if/when I need to. This has already eaten up more time and stress than I care to receive. Idk, maybe I should contact the Berlin office directly. Or, I can just sell them and move on

You can argue that I'm being too patient (tolerant) with them, but the truth is, I'm not looking for a fight. I just want monitors that work, and these don't

yes. contact the berlin office. its obvious your not looking for a fight, but ya know, thats what companies count on in this case, don't me the nice guy.

Well, I contacted the office in Berlin with some strong language about my dissatisfaction, and the response was: I'm sorry to hear you are having trouble. The guy in New York will take care of you

I got the manager from Guitar Center to give me some hope (he said he'll look into it), but Adam is a very weird company. For whatever reason, they are not interested in replacing the monitors. It's like they don't want to admit what is going on?

So, they are claiming they installed a new speaker and amplifier, and are sending it back. Thanks for the feedback guys.

And they've heard the clip of it buzzing and know of the buzzing issue from earlier models?

I sent them clips, yes. I'm not sure they know of the buzzing issue from earlier models though

I remember the thread from GS, i just did a quick search and came across this: http://www.gearslutz.com/board/so-much- ... -buzz.html

So it looks like you might have to persist with Adam. I would anyway, hopefully you'll get the resolution you want.

I had buzzing on one of my ADAM A7's (the orignals, not the A7X). In fact, mine are very early A7's with the old dome shaped volume knobs. Anyway, I eventually contacted ADAM, they had me send it in for service in NYC (which is fine since I'm less than 9 miles away from Manhattan). I took the speaker in question to the service center, which was nothing fancy (just rented space in an old warehouse), and a few days later they called to say they found the issue: ADAM had accidentally glued two covers in the center of the woofer. The repair involved peeling it off, and everything was fine. My point: the place in NYC is legit, they'll take care of you. Based on what I saw when I was there, they do a lot of gear outside of ADAM.

I lost my RME Fireface 800 during hurricane Sandy (the power went out abruptly and the Fireface never came back on). I got it back when those were relatively new, so it was well beyond warranty, but it was still a lot cheaper to repair it than to replace it. It sucks, but one of the "joys" of owning hardware is having to get it serviced.

What about the "lemon law" that protects American consumers from being subjected to poor quality and repetitive repairs for the same defect? My situation has been well documented and is a persistent problem (as noted by others on the other forum, as well).

If I experience the same thing again, and they refuse to replace it, I may very well have a legal case for a defective product under the lemon law. Am I off base here...?

If they come back from repair and still don't work, then by all means, contact ADAM and ask for a replacement. But, send them out first, and see how they come back to you.

They finally got me sorted out with a new pair of monitors; not without extensive back and forth to prove my case though. I wasn't exactly delighted with their customer service, overall. All that ends well, is well, I suppose.

Fwiw, I'm still not particularly happy with the low end at mid-higher volumes; there is a good deal of port noise on certain frequencies that makes me cringe. Let's just say I'm not entirely comfortable cranking these up, even for short periods. Idk, maybe a sub is in my future at some point, but my room is likely too small to handle it.

I don't have Adams - but I experimented a bit with ports.

You can even do part of the room tuning with blocking the port at different locations in the tube. The resonating frequency change as you do this.

So combine switches and blocking ports to tune properly.

But it does differ depending on which frequeny ports are to enforce. Some speakers are clearly not for bass only.

So which is the best alternative to the Adam A7x but without that pod noise.

Idea?

Inside one of my A7x the psu cooler starts to ring if it is driven by a short impulse such as a Kick... I just send it back, hopefully they can fix this issue, othercase I need an alternative.

Idk, maybe a sub is in my future at some point, but my room is likely too small to handle it.

Sealed subs are real good for small rooms, because they can drive the room down into the "pressure frequency region", lower than the room's lowest modal frequencies.

In other words, below the room's lowest modal frequency, bass can be real good because the sealed sub just slightly pressurizes the room's air when the cone moves outward, then slightly de-pressurizes the room's air when the cone moves inward. Also sealed subs tend to have better phase response and smaller group delay. Ported subs don't do as good as sealed subs in small rooms.

Works best if the room is acoustically treated as good as possible of course. In small rooms, there's not as much free space to fill with fiberglass.

My office is 15 feet X 11.5 feet, not very big. Treated pretty good but it could be better. I'm using a homemade sealed sub with an 18" woofer and 500 watt sub amp. It does pretty clean flat bass down to about 25 Hz, not a lot of rolloff down to 20 Hz. The system can run lots louder than I ordinarily listen at. I usually try to listen around 80 dB spl and no more than 90 dB spl, C weighted. But it can work clean and low lots louder than that.

[blueman]

Interesting! I eventually got the A7Xs replaced (under warranty) but my bass response is not great, mixing in what is effectively a cube: length and width are nearly identical. How important is it to go with an Adam sub vs. KRK or another brand?

Thanks for the feedback

Hi Blueman. I don't know enough about current commercial studio subs to recommend a brand. Maybe somebody else knows better.

If it were me I'd shop for sealed rather than ported subs, just because they tend to be better behaved especially in small rooms. As far as I know anyway, which isn't much. The ported subs can get louder down to a certain frequency, then they unload below the cutoff frequency and don't do anything. The sealed ones need more power, but can go way down there assuming it is a heavy duty item. And the sealed ones can drive a small room well below the lowest modal frequencies.

Have you tried to acoustically treat your room? If the room isn't pretty heavy treated (heavy treatment generally needed for good bass control) then maybe the A7X is doing the job, but your room has deep nulls at unfortunate low frequencies so you don't get to hear what the speaker is doing.

Apologies if you already know more about it than I do. If the room isn't treated, then money might be better spent on treatment before any money is spent on a subwoofer.
