![]() ![]() If you are predisposed to having that bias against a waveguide design you can throw that out the window here. There is no “shoutiness” that plague the designs of old (or current, lesser designs). The JBL HDI-3800 possesses a great waveguide. Good waveguided-horn designs to not exhibit this characteristic. Horn designs tend to be looked at with this nostalgic tendency to think they are “shouty” or “boxy”.This coincides with a slight ripple in the impedance graphic around this frequency as well. This could be what I was hearing as problematic in this region. When looking at the horizontal radiation pattern you can see the data shows approximately a ☑00° radiation pattern at around 300Hz but then sharply drops to about 50-60° by 350-400Hz. At this point, I’m not entirely sure what the culprit is. There was something in the lower midrange (I ballparked it at about 200-300Hz) that I just didn’t like where lower female vocals tended to sound more boxy than I felt was right.Overall tonality of these speakers was good but I wouldn’t put them on par with their Revel counterparts.At 45-inches tall and 83 pounds of pure awesomeness with triple 8-inch woofers these speakers command your attention. ![]() I encourage you to watch my YouTube review for more details but a quick few notes: Overall, what we see here is that the anechoic data can be conveniently used to predict the actual response one would expect to see in their own room. The dip from 150-400Hz is caused by the rear wall and/or couch as when the microphone is moved into the center of the room the dip fills in. Aside from the room dimensions, my couch, the back wall behind where I sit, the end table and the lamp near the listening position all influence the measured response. The room takes over as you enter mid-to-low frequencies. Below this we see more deviation from the prediction. The prediction is quite accurate down to approximately 600Hz. ![]()
