Plimpkin Posted May 11, 2010 Share Posted May 11, 2010 I just picked up a pair of kg 4s. I have never heard a pair before, but I have heard that they should sound pretty good. They do seem to have a great clear sound but the bass seems to be missing. Even when I turn bass up and he treble down it seems weak and worse in one speaker than the other. To the untrained eye all of the speakers appear to be in decent shape. Is this a crossover issue? I think the speakers are from 1984.

It very well could be, or bad woofer(s) The Kg4's bass is into the 30's and quite potent. With the grills off: are both woofers on front moving like they should? The KG4 is a 2-way and the woofers work togeather to drive the passive radiator on back. Quote Link to comment Share on other sites More sharing options...
Dale A B Posted May 12, 2010 Share Posted May 12, 2010 I have KG 4's and had an issue with one of the k-8-k's, which was inoperative. I would check each of the 4 of them first. I've seen plenty of complaints about this driver on the board, and would suspect them before the crossover. I see them pop up on ebay, and when I replaced mine, got a pair for $50. So, in my mind, the k-8-k is the weakest link on this model. Good luck on your journey - hope it doesn't cost you much to get them up to 100%!

Plimpkin Posted May 13, 2010 Author Share Posted May 13, 2010 I checked each one of the 8" speakers and they all seem to be working. I gently touched the center part of them while they were on and I felt vibration. Is there something else I should do to check them? Quote Link to comment Share on other sites More sharing options...
4tay Posted May 13, 2010 Share Posted May 13, 2010 I remove the drivers and ohm them to make sure before moving on to the crossover. Could be one has a partially burnt voice coil. Quote Link to comment Share on other sites More sharing options...
Plimpkin Posted May 13, 2010 Author Share Posted May 13, 2010 Thanks for the advice! So I remove the speaker from the front of the cabinet, disconect the wires and look for a reading of ? Ohms. Quote Link to comment Share on other sites More sharing options...
4tay Posted May 13, 2010 Share Posted May 13, 2010 IIRC, reading across the driver leads you should get 6 ohms. Quote Link to comment Share on other sites More sharing options...
