Frequently Asked Questions
What amplifier power range works best with these speakers?
These speakers handle 50W nominal and 100W maximum at 8 ohms. For clean reproduction with adequate headroom, a receiver or amplifier delivering 20–80W per channel into 8 ohms is ideal — pushing them harder risks thermal compression in the woofer without meaningful SPL gain.
How wide is the dispersion pattern, and does the tweeter angle?
The 3/4" titanium silk dome tweeter pivots, allowing you to aim high-frequency energy toward the primary listening position even when the speaker is installed off-axis. This is especially useful in rooms where the cut-out location doesn't align with the sweet spot.
What is the low-frequency extension, and will these handle bass without a subwoofer?
Frequency response begins at 68 Hz, which means meaningful bass content below 80 Hz will be absent. In any serious home theater or music system these should be crossed over to a subwoofer — running them full-range will stress the 5.25" woofer and produce audible strain on low-frequency transients.
Can the grilles be painted to match the wall?
Yes. The metal grilles are paintable, allowing them to blend with any wall color. Use a light application of latex paint to avoid clogging the grille perforations, which can affect high-frequency transmission.
What is the cutout size required for installation?
The cutout requires a 6.9" (175mm) diameter opening. The overall baffle measures 8.3" (213mm), so plan for that footprint when templating — the included cutout template simplifies marking.
