Tweeter TW28

hello and welcome to my vintage audiophile channel this is now my 34th video hoping that all my subscribers and everybody else here looking at this video is staying safe and following the rules and stay in virus free today I'm gonna be reviewing a pair well actually not a pair there's two different types here there's it's the realistic 40 - one three one zero super tweeter and they started making them around seventy five seventy six and they made three different iterations of this particular one the first one that they made was the 1310 they also had a 1310 a and at 1310 be the 1310 and the 1310 a are basically the same they just put a different number on them I have a feeling they probably changed something maybe like a different resistor no crossover something because I they are internally crossed over they are made to be added to any speaker that is out there you hook them up directl
