SA10 reading 3ohms

[tc300 10+ year member]

i picked up a pair of sa10s D2 from the sundown yard sale few months ago, showed up new in the box... went to wire them up and decided to check the coils... well each coil on both subs is reading exactly 3ohms. is this normal...???!?!?

Probably the variance in your dmm. But I'm sure its more like 2.4, 2.5. As long as its not a stupid ohm like 30 and or jumping all around it should be fine. Check the coils if they are shiny new you may have just got a QC fail that had d4 coils instead of d2 like they shipped as. It is yard sale sub's.

Its normal for subs to read a little lower...they seldom read higher...like shaun said ...it seems you got dual 4s ...

Check your DMM see if it's reading right 1st of all. They can be finicky at times.

The actual number for coil impedances will be either slightly lower or higher than the actual ohm on said sub.

What gets me is your just now checking out the subs esp from the YS?? I woulda checked those things 100% inspected before asking a few months later...

i did that already.. have two other subs laying around and they ohm'd out right could they have d4 ohm coils instead of 2 ohm???

I had this with my soundqubed subs. Touch the two leads together and see what it reads. Mine was .5 & other .8 off.

they were brand new out the box. kinda hard to believe they were in the yardsale. not a scratch on them!! i did test them out to make sure they played and they passed.

it reads .5 also...

Then your right around 2 ohms. Your all good

I can almost guarantee they aren't "brand new".

Your overlooking something.....could be as simple as too much excess glue or a small blemish.

I have boughten from the ys before so I know.

only thing i did notice there wasnt much glue for the surround and frame joint.. im leaving the gasket off in case it becomes an issue..

these were the ones from the "box up area"
