    Braun LV 720 Speaker Thread

    Bratwurst7s Congratulations, these are unique LV 720 speakers. Are you going to restore them for yourself? I also bought a second pair of LV1020 in the USA, everything is original and I don’t change anything on purpose so that I can always compare the sound of the original and what I conjured...

    Braun LV 720 Speaker Thread

    Logically, the LP720 PS is better, but in the LV 1020 there is a midrange with a huge magnet , but the sound is much better in the mid frequencies than in the LV720. The instruments sound much more realistically like live music at home, excellent attack, expressiveness. ... For my ears, the...

    Yes, I watched this auction, 'that's certainly a gift. For the summer I moved from the USA to Russia and then bought an LV720 for $ 550, knowing how the lv1020 triamp sounds, I took a chance.

    Rule of thump to identify Caps in signal path

    Many capacitors take a long time to break to enter a constant mode of operation, because of this there are many hasty conclusions about the effect on sound. I recommend that you look at this link where and which WIMA film capacitors should be used ...

    Stiffening fatigued speaker spiders

    I have the same problem on vintage 12 "woofers. It can be seen that the spider does not hold the cone at the required height and sags. At volume the coil began to knock. I bought other woofers, they are the same ancient ones, but their course is a little harder. Bass appeared, but it's still not...
