TC dual 2 ohm is reading 2.8 on each coil. ??

I'm planning to get rid of this sub but before I do so, why is each voice coil reading 2.8? Is something wrong with the sub? Sub is a Lms-R.

Look up T/S specs. They post the actual dc resistance.

Coils aren't always exactly what they are labeled.

I have a pair of the LMS ultras. Been playing them about 10 months. I just built a new enclosure for them. I checked my coils before installing them again. All four read exactly 2.0 Ohms.

When I measured mine I put my VM leads under push terminals. took about a minute for the Ohms to settle down to 2.0.

Hope this helps.

Also you might be getting the .8 from the leads. Touch your leads together and see what they read mine was .5. Whatever it is you deduct that from your readings.

That's normal.

So 2.8 being normal, is my 2 flat reading abnormal?

2.8 IS NOT normal nor is a flat 2 usually you'll see a lot of BS here just have to learn to wade thru it and pick truths out. Almost all DMM's will read somewhere over or under the desired Ohm's. The leads almost always add a few points. The trick is to touch the two leads together and see what you're getting. My DMM consistently reads .5 when I touch them together thus making my dual 4 ohms coils read 4.5 each.
