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.

JBL HDI3800 Triple 8-inch 2-1/2 way Floorstanding Loudspeaker with 1" compression tweeter

Designed and engineered in our world-famous Acoustic Engineering Center of Excellence in Northridge, California, Stage 280F is the flagship of the new JBL Stage Series. This floorstanding loudspeaker features a 2.5-way design with Next Generation patented High-Definition Imaging (HDI) waveguide geometry, 1-inch (25mm) Anodized Aluminum dome tweeter, and dual 8-inch (200mm) Polycellulose cone woofers that provide deep, signature JBL bass.

702 S3 is our 700 Series flagship: a state-of-the-art floorstanding speaker that defines standards for performance in its class. Its Carbon Dome tweeter is housed in a Solid Body Tweeter assembly, derived from 800 Series Diamond. That ensures even more realistic treble, while its decoupled midrange assembly, enhanced here with our revolutionary Biomimetic Suspension, provides outstanding midrange transparency and openness. And thanks to its downward-firing port configuration and its trio of Aerofoil Profile bass cones, 702 S3 can deliver bass that’s both profoundly deep and endlessly articulate. If you want the best in the series, this is it.

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.
