sicklife17 Posted February 13, 2015 Report Posted February 13, 2015 I just picked two alpine type r's for $20 the guy said he had them hooked up and they sounded terrible one was buzzing and the other wouldent work. I dident hear them when I got them but they don't make any noises when u press in the surround and nothing smells burnt. I just put a volt meter on them and one cool is 4 ohm but the other is about 6 give or take. Is this normal for a dual 4ohm sub. If not what could this mean?
Nick580 Posted February 13, 2015 Report Posted February 13, 2015 do you hear any scratching/ abrasion when you push down on the cone? if so then the coil is no good which means the sub is no good unless you can find a recone somewhere. For $20 i would have expected them to be blown.
SIDE SHOW Posted February 13, 2015 Report Posted February 13, 2015 still $20 is a decent deal, look into a recone kit
sicklife17 Posted February 13, 2015 Author Report Posted February 13, 2015 Nope there are no sounds comming out of them when u press down and they are still stiff. Only thing that's throwing a flag for me is that they each have one coul reading 6ohms
Nick580 Posted February 13, 2015 Report Posted February 13, 2015 There might be some usefull information for you here = http://www.stevemeadedesigns.com/board/topic/115718-alpine-type-r-12-recone/ If you have a way to power them you could just do a quick free air test. Now they wont sound great since they are just raw speakers without an enclosure but at least you can see them move and asses any problems that may occur.
sicklife17 Posted February 13, 2015 Author Report Posted February 13, 2015 I'm going to hook them up to my amp tomarrow possibly I really Don't want to pull it all apart but it is what it is. Could the 6ohms mean anything?
Broke_Audio_Addict Posted February 13, 2015 Report Posted February 13, 2015 Any movement or noise at all will affect your measurement. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
sicklife17 Posted February 13, 2015 Author Report Posted February 13, 2015 I think there blown. Now I'm getting 2 and 3 ohms on them
Broke_Audio_Addict Posted February 13, 2015 Report Posted February 13, 2015 See my above post. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
sicklife17 Posted February 13, 2015 Author Report Posted February 13, 2015 There was no movement or noise I was sitting on the floor with them in the house
