JBL HDI3800 Triple 8-inch 2-1/2 way Floorstanding Loudspeaker with 1" compression tweeter
Q: WHAT ARE THE CROSSOVER POINTS (FREQUENCIES)
A: Our JBL HDI-3800 crossover points are as follows: 800Hz, 1800Hz
Q: Can I use these speakers with a vintage marantz 2325 stereo receiver which has 125 watts
A: undefined
A: I’ve used them with a Denon 3600 with Audiocontrol G4 amp and Arcam PA720. I preferred the G4 amp because it had more power. I just tried them with a JBL SDR 35 and it’s the best they have sounded so far. Late but hopefully helpful.

These are phenomenal home theater speakers. I stepped up from KEF LS50s which were great. But these take it to a whole other level. They play deep and authoritative. The compression driver makes it feel like bullets are flying through the room. I run them full range. After testing with multiple amps I hooked them up to a JBL SDR receiver and they sound even better. I listen to a lot of the Black Keys. These speakers to an amazing job in two channel as well. They are forgiving enough that bad recordings still sound smooth.
