Replacement for Klipsch KG 4.5


Question

About 2.5 years ago i bought a pair of klipsch KG 4.5's and they've sounded great up until recently. They are able to pump out a lot of sound from my a low wattage (low budget) receiver....

Unfortunately The Tweeter horn on the left speaker has started to make some wierd sounds (Most noticable when listening to music on the very high notes..)

Could the reciever maybe be causing the "Wierd sound" im hearing ... ? I've been considering replacing my Onkyo receiver for a new one but can't afford it if i have to replace my front speakers.. D:

personally im thinking it's the speakers because of their age mainly, therefore i've started to look for a replacement... 

A pair of Infinity Alpha 50's has recently caught my attention, but i'm not really experienced in the "Home theater scene", I just happen to enjoy alot of sound... :)

So i was wondering if my Onkyo HT-RC630 will fall short paired with the Alpha's...? 

Here's a full list of my home theatre setup.. 

Front : Klipsch KG 4.5

Center : Klipsch RP-440C

Back : Jamo Classic 8

Sub : Klipsch R-112SW

Reciever : Onkyo HT-RC630

 

Also, here is a bit of specs on the  Infinity Alpha's:

  • video-shielded.
  • bass-reflex.
  • frequency response 35-22,000 Hz (±3dB)
  • 8-ohm impedance.
  • sensitivity 91 dB.
  • handles up to 200 watts.
  • dual 5-way binding posts.

 

Any input is appreciated! :)

First you need to troubleshoot the source of the problem. Check your connections at both ends to make sure they are tight. If the connections are not the problem, reverse the speaker cables; feed the right channel with the left cable and vice versa.  If the receiver is at fault, the problem will move to the other speaker.

 

Speakers should play for 20 years with no issues assuming they have not been abused. How loud are you playing the system? Overdriving (clipping) the amp causes distortion, which is the most common cause of tweeter damage. 

 

If the tweeter has been damaged, repair is fairly simple, just unscrew the tweeter from the baffle and remove the clips connecting it to the crossover, install the new one. The manufacturer should  be able to supply a replacement for not much money. If not, you can ask for help at diyAudio.com.

If the problem stays with the speaker when you swap amplifier channels, there is one other step you should take. If the tweeter is easily removed, you should swap it between speakers. If the problem follows the tweeter, the tweeter is bad. If it stays with the speaker,

there is probably a bad capacitor in the crossover and the crossover will need repair/replacement.
