Frequently Asked Questions — ULTIMATE OD6T
How can it be mounted?
Into the ground using the SPKA-STAKE-OD-18 ground stake, or on an exterior wall, fence post or tree using the SPKA-SMK/TREEMK-ULTIMATE-OD6 bracket. Neither is included.
Can it be used on a 70V or 100V system?
Yes. A built-in transformer provides 75 W at 70V and 150 W at 100V, alongside 8 Ohm operation.
What is the difference between the two finishes?
OD6T-BRZ-T-EACH has a bronze textured finish; OD6T-PRIMED-EACH has a primed finish that can be painted to blend with the surroundings.
Why a ribbon tweeter?
The co-located 3 in. planar magnetic ribbon tweeter and woofer give phase coherence and wide dispersion (110° x 75°), resulting in a larger listening area.
Is it sold as a pair?
No. Each part number is a single speaker (EACH).
