The JVCs that I have are 71mm tall from mount to magnet, they were pretty close to the window I would say 80mm max.
funny you say that because I recommended the $20 option and not the $200 one. It’s all about value, paying more for quality is good, more for shit is pointless.
you voted for either 20$ or 200$ and nothing in between. thats the problem. your opinion is that anything but high priced stuff sounds like garbage and thats just not true. its all in the ear of the beholder. if they like it then its fine.
next youll make some statement like “well those people that like to listen to their music on 100$ speakers have crappy ears and dont know anything about anything” when in 5 years some new speaker will come out and youll be calling your “good” current setup garbage. buying high priced audio, being super fussy about sound and telling others that they are dumb when they dont is really whats “pointless”
