cracking noise in reference

[Tony.ca]

Hi there,

I own a pair of paradigm v.2 reference floorstander loudspeaker and i have a problem with it.

When i crank up the volume to a certain level the mid range starts to jarr,like it's bottiming out.I thought the bass was too high so i connected another pair of paradigm studio v.2 and its sounds perfect with the same volume.

Can someone please help me figure out this problem since the floorstander should be able to take up more volume than the studio.

Thanx,

Tony

We can help you, but Paradigm isnt the first to have a say? Did you contact them?

I did ,they want me to take it to a dealer and so on ,was wondering if I would be able to fix it with of course any help i can get from this forum.

Thanx,

Tony

Sounds like clipping to me - maybe try a more powerful amp.

Rob,
He said he switched speakers and it was fine.

Tony,
is the driver moving enough to be bottoming out? Are you able to do any testing?

Hi Cal,

He said he switched speakers to a different model - maybe the other speaker is a different impedance / easier to drive.

Never mind. My bad.

I thought he said he simply connected more speakers. This would indeed have allowed him to get more bass volume, but not necessarily better sound quality. (J6P+$=Severely Disrepected Gear)

A possibility.

It seems like that, something broken in the Xover of mid. the bass F power was into mid-driver and made it bottoming.

Smells like a mechanical defect. Maybe some bad/loose glueing in neck/spider region.

I was wondering if it might be a failed cap also.

Let's hope he can determine that before going on to the XO.

Im surprised nobody asked; is it the left, right or both speakers making this noise?
You said it was the mid, have you unplugged the tweet and woofs to confirm this?

 

[Cal Weldon]

Let's give him the benefit of the doubt for now.

I did all the things thats mentioned in this forum.The problem's the same.


It's both the right and left speaker which is doing this.


Another set of speakers that I connected it to check were the same company paradigm studio 40 which is more like a bookshelf,it sounds fine

It's not bottoming out it just makes the cracking noise after increasing the volume and it's coming from the mid.


Another thing i did was,I connected just the tweeter and the mid using the top bi wire and it was fine. But when I connected all together with the two woofers it starts to crack again.and when I bi-wire it still cracks.


Thanx,

Tony
