Hi folks
For anyone with the passive 110's, have you ever measured what SPL you are getting before they distort? I am measuring with a phone app, so certainly not accurate, but I get a popping sound at around 80-83 db approx 12 feet away. Difficult to be certain but I believe it is from the mids. I am using the ADA 1500 - 4 channel, so power should not be an issue. Always noticed on the right speaker but when I isolated the left it also began to pop at higher volume. I have an old set of cerwin vegas that I swapped in and they are noticeably louder. Not what I would expect. Don't get me wrong the LFR's sound far superior to the vegas but I like it loud. Anyone have a similar experience?
Hi Mojo I didn't think there was a ver. 3 of the LFR's but I will check on my invoice to see if it gives the ver. It isn't written on the back of the speaker. They do have the white dust caps if that is any indication.
Looked at the invoice and it doesn't allude to the version either. They were purchased late 2017 if you happen to know the history of when the various versions were introduced.
The original LFRs were v3. They also had white dust caps. But if you purchased them new in 2017, they must be v4. I ask because the v4 mid-range is an improvement over the v3.
I have the active LFR1100 and don't have a similar problem. I've had them playing 116 dBC peaks at 10 feet away full range. No popping. Popping is a sign the driver is damaged or is moving beyond its limits.
I suggest you take this up with Axiom directly.
P.S. 80-83 dB at 12 feet away is not much. Likely that phone app is not good for the intended use.
The app may be in dbA not dbC.
Typically reads 10db lower depending on range. Even still, that is not very loud. Peaks of 83dbA are loud but not uncommon at moderate/high listening levels. Definitely not in the “11” zone.
Thanks Guys. Ya, I am sure the app isn't very accurate. It is loud but not Saturday night loud. Mojo...I agree, it does sound similar to the popping I have had when a sub is over extended, only at a higher frequency. I think maybe I will contact Axiom and perhaps drop it off. I would also like to get a couple of dented dust caps replaced if it isn't a major deal to do so.
Rodents in the drivers will also make a popping sound. I think you know something about that...LOL!
The over extension theory got me curious and I compared the travel of the drivers in each speaker. Oddly enough it appears the one that is popping is moving less (not just one but all drivers in that speaker). I guess this is just another reason to take it in to see the Axiom Doc
Ya I think the rodent prob has been dealt with. I murdered the buggers.
Oddly enough it appears the one that is popping is moving less (not just one but all drivers in that speaker).
What do you mean by not just one but all drivers in that speaker?
All of the drivers on the front of the speaker in question appear to travel less than that of the other speaker. If it were a problem with over excursion I would expect to see the opposite.
Not sure if you’ve tried this or not but....Might be good to swap the speakers from left to right and rule out the amplifier or pre. It would confirm it’s the speaker / woofer if the issue travels. Then at least you know that much before making the trip to axiom.
Edit: I just re read the post. Seems the cerwin Vegas worked properly with amplifier. Might still be good to swap channels though and just see what you get.
It would be worth doing what Kodiak suggested.
If it's not the amp channel, it's quite possible the cross-over responsible for the front drivers has failed.
You can fix this problem by trading them in for the actives.
I would love to go active. Someday I will but not today
. I think I will try the switcheroo as Kodiak suggested and report.
It's not like you are hurting with passive LFR1100s.
There should not be any popping at any volume level. Even severe amp clipping should only get harsh sounding and force you to want to turn it down. If you isolate it to one of the drivers we can replace that for you no problem. If you want to bring them to the factory we could check everything for you. If it is going to take a while we can always loan you a pair of Actives in the meantime
I think my M2s are having some kind of problem that I can't describe. I might need actives on loan while you try to finger out my M2 woes. :p
Agreed Mojo. Good call. My refurbed m60ti need another refurbish. I’d be fine with M100s and a couple of ADA-1500-2. And yes it’s no problem if it it takes a while to refurb my m60s. I can wait 21 business days to get my m60s back. Axiom is the best.
You'd love the M100s in that room. They are so warm and full sounding.
Any update norap? Still popping noise? Any chance evidence ftom switcheroo?
