Köp in diskanter, laga upp till det skicket och sälj dyrt.
Det måste finnas flera hundra som skulle köpa renoverade diskanter som dessutom mäter som dom ska.
Att den första du lagade inte mäter ok kan ju bero på att du limmade omkretsen också vilket gjorde den för stel i rörelsen.

NEW TWEETERS REPLACING MT20HFC
If you really want your Carlssonspeakers, which are designed with the MT20HFC to give their best, you should think about up-grading them with new tweeters. The Peerless CT 62 is an excellent replacement with only a fraction of the distortion of the old tweeter. The CT62 is almost a direct replacement, no modification to the crossover is necessary but the physical dimensions are not exactly the same. PROS:
1. They fit under the grill of all Carlssonspeakers using the MT20HFC 2. The have a very clear and distinct sound that transforms old Carlssonspeakers to the most realistic reproducers of music (If you also have seen to the woofers) 3. They are available in the specified impedances 8 and 16 Ohms. 4. They are cheap! CONS:
They are a bit cumbersome to install, as they are slightly bigger than the old tweeter. They are 61mm instead of 50; they have another type of magnet and do not have a square front. Therefore they are not easy to mount ”standing” on the baffle. It is also impossible to use the old bracket from the MT20HFC.
ASSEMBLY:
Prior to installation of the CT62 remove the blue and white sticker on backside of the tweeter. The glue tends to dissolve the adhesive on the sticker and the tweeter might come loose. Depending on the model there are three possible ways to install the tweeter.
1. WOODEN BAFFLE (OA-4/5/6)
Get brackets, bend them to the correct angle and screw the to the baffle in the original places (alternately in the ”Y-configuration). Drill holes in the brackets and the baffle for fixating the tweeters. This will later prevent the tweeters from twisting due to strong magnets. Hold the tweeter in place and mark on the baffle where the front will meet the baffle. Remove the tweeter and cut a groove in the baffle to support the frontplate of the tweeter. See to that you will get the right angle of the tweeter. Apply strong glue to the groove, the brackets and the magnet. Screw the tweeter in place and allow the glue to set. Solder the leads in place. The wider tag is plus, the smaller minus.
