Can anyone suggest an upgrade tweeter for replacement? One of them went bad (no sound.) I will test with meter but likely need to upgrade anyway.
Thanks.
Thanks.
In general if they have the parts they are very reasonable... but that has been a big if.Have checked replacement parts from Harman? Few years back I fixed a pair and the price was very fair.
No, I did not even think about that. Thank you. This speaker is elevated on top of an entertainment center. I did not bump it. It's just old. What if I just replaced both tweeters? Are there not general tweeters that I could swap in? The crossover is already there right? I should not have to do much. Tweeters should be designed...to tweet (aka accept the crossover frequency.) Matching ohms probably matters.Are you sure it is the tweeter and not a crossover component 'upstream' of the tweeter?
By all means, you should check the tweeter for an open voicecoil (either with a DMM or VTVM, or by using a pair of clip leads and a small 1.5 V battery (e.g., an "AA" size "penlight cell) and listen for static as you complete the circuit). If the VC is OK and/or the tweeter itself can be demonstrated to "work" with the battery test, the problem lies elsewhere.
IF the tweeter is actually bad. You should replace like for like (i.e., a new or used "Infinity Primus 360" tweeter). eBAY may well turn up one (or more) used ones. New (NOS, "new old stock", or a replacement from Infinity) might be difficult to find. EDIT a search on eBAY only turned up a pair of generic replacement domes with voicecoils from China, which might be quite difficult for a beginner to install and align properly.
Otherwise, you will have to match the sensitivity, impedance characteristics, and Fs (resonance) of any putative replacement tweeter very closely to the original and/or you'll have to revise the crossover to accommodate the replacement. If you change one tweeter to a different type, you'll pretty much "have to" change the other one to match it, especially if crossover modifications are involved.
Did you abuse the loudspeaker(s)? Is there no protection for the tweeter (fuse, or something like a "Polyswitch" self-resetting fuse)? In other words, do you know why/how it happened, and how to prevent it from happening again?
Simply swapping one tweeter for a different one can be a mare's nest. The crossover was designed for the impedance curve and FR of the original tweeter. Unfortunately (or fortunately?) they are not like peas in a pod, all having the same characteristics.No, I did not even think about that. Thank you.

Good point on verification. Tweeters like this fail easily and crossovers rarely do, but it is best to verify.As mentioned above, you need to make sure it is the tweeter at fault and not the crossover.
If the crossover is at fault you can change the tweeters to what ever you like, one still will not work.
You can purchase parts online.
