Why the Dymension BL-650 Stands Out
From the moment you place the BL-650 in your landscape, its rugged mineral-filled enclosure and sleek bollard profile hint at the sonic sophistication within. Timbre-matched to the entire Dymension series, these bollard speakers ensure a seamless tonal character whether you mix and match with in-garden units or indoor satellites.
• IP56-rated for protection against dust, rain and salt spray
• 1” Dymension aluminium oxide dome tweeter for crystal-clear highs and detailed imaging
• 6.5” mineral-filled woofer plus a 5.5" × 10" passive bass radiator for effortless, distortion-free lows
• 8 Ω / 70 V / 100 V multi-tap settings for flexible distributed-audio installations

At the heart of the BL-650 lies Definitive Technology’s commitment to advanced acoustics. The 1” aluminium oxide dome tweeter sits atop a rigid, mineral-filled chamber, delivering crisply detailed treble up to 24 kHz (–3 dB) with pinpoint imaging. Below, a 6.5” mineral-filled woofer tackles midrange frequencies with authority, reproducing vocal nuances and guitar harmonics with astonishing clarity.
But the secret sauce is the integrated passive bass radiator. At 5.5” × 10”, it works in tandem with the woofer to enhance low-end extension down to 44 Hz (–10 dB), all without adding bulk. The result? A natural, full-bodied bass response that remains tight and punchy—even at higher volumes.
With a sensitivity of 87 dB (2.83 Vrms/1 m) and a recommended amplifier range of 20–150 W, these bollards can be driven by a modest hi-fi amp, AV receiver or 70 V/100 V distributed system. Whether you’re entertaining guests or enjoying a quiet evening under the stars, the BL-650 delivers balanced, dynamic sound.
Durability & Installation
Outdoor speakers must endure the elements—and the BL-650 excels here. Its rigid, mineral-filled enclosure is acoustically inert yet impervious to moisture, UV and corrosion. The IP56 rating means it’ll shrug off rainstorms, garden sprinklers and salty coastal air.
Installation is straightforward, thanks to a flanged base with pre-drilled holes for deck screws or concrete anchors. For lawn-based setups, simply swap to the included ground spikes and position your speaker anywhere you like. Multi-tap transformer settings allow clean wiring for both low-impedance (8 Ω) and high-voltage (70 V/100 V) systems—ideal for large estates, restaurants or poolside entertainment zones.
