The towers and center are 4-ohm speakers, which means they’ll draw more current – a quality amp rated for 4 Ω will ensure they deliver full dynamics. Aim for ~100 W per channel (or more) for the HDI-3600\/3800\/4500.

The HDI-3800 is larger, with three 8″ woofers, so it can play a bit deeper bass and get louder – ideal for big rooms or if you crave maximum impact. The HDI-3600 uses smaller 6.5″ woofers in a slimmer cabinet, which is great for medium-sized rooms or where space is a concern. Both sound very similar in tone (same tweeter), so you won’t lose any quality choosing the smaller one; it’s more about how much bass and room-filling volume you need.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I mix HDI speakers with other JBL speakers I already have?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYou can, but for the best home theater experience we recommend keeping your front stage all HDI. That ensures identical timbre across your front left, center, right (since all HDI models use the same horn and compression driver).

JBL HDI‑3600 6.5-Inch Floorstanding Speakers with HDI Waveguide
JBL’s HDI‑3600 delivers audiophile performance in a slim 2.5‑way tower. Its High‑Definition Imaging waveguide works with a 1‑inch Teonex compression driver to produce accurate, room‑filling treble, while three 6.5‑inch Advanced Aluminum Matrix woofers supply clean mid‑bass and articulate lower registers. The bass‑reflex cabinet uses a rear port for extended low‑frequency output, and the elegant finish options fit seamlessly into living spaces.
With a sensitivity of 90 dB and 4‑ohm impedance, the HDI‑3600 is easy to drive yet capable of handling up to 250 watts for dynamic listening sessions. Its precisely tuned crossover at 900 Hz and 2 000 Hz ensures a seamless transition between drivers, offering a balanced frequency response from the high 30s to beyond 30 kHz. Rugged construction and high‑quality binding posts round out this refined floorstander.
JBL HDI‑3600 Key Features:
High‑Definition Imaging waveguide provides wide dispersion and consistent sound staging.
What is the benefit of the HDI waveguide on the HDI‑3600?
The waveguide shapes the dispersion of the compression driver so high frequencies remain smooth and consistent off‑axis, delivering a broad listening area with minimal reflections.
How does the 2.5‑way design differ from a 3‑way speaker?
In a 2.5‑way design, one woofer handles midrange frequencies while the other two focus on bass, improving efficiency and reducing midrange coloration compared to a standard 3‑way crossover.
What amplifier power should I use?
The HDI‑3600 performs well with amplifiers providing 20 to 250 watts per channel, making it compatible with mid‑powered integrated amps and larger separates.
Do the three 6.5″ woofers provide sufficient bass?
Yes, the triple woofers and rear‑port design allow the speaker to reach down into the high 30 Hz range, offering ample bass output for music and movies.
Can I bi‑wire the HDI‑3600?
The speaker features a single set of binding posts; high‑quality speaker cable and a stable amplifier are recommended rather than bi‑wiring.

High‑Definition Imaging waveguide provides wide dispersion and consistent sound staging.
What is the benefit of the HDI waveguide on the HDI‑3600?
The waveguide shapes the dispersion of the compression driver so high frequencies remain smooth and consistent off‑axis, delivering a broad listening area with minimal reflections.
How does the 2.5‑way design differ from a 3‑way speaker?
In a 2.5‑way design, one woofer handles midrange frequencies while the other two focus on bass, improving efficiency and reducing midrange coloration compared to a standard 3‑way crossover.
What amplifier power should I use?
The HDI‑3600 performs well with amplifiers providing 20 to 250 watts per channel, making it compatible with mid‑powered integrated amps and larger separates.
Do the three 6.5″ woofers provide sufficient bass?
Yes, the triple woofers and rear‑port design allow the speaker to reach down into the high 30 Hz range, offering ample bass output for music and movies.
Can I bi‑wire the HDI‑3600?
The speaker features a single set of binding posts; high‑quality speaker cable and a stable amplifier are recommended rather than bi‑wiring.
