DLS RC6.28 component speakers received an EMMA product highlight on October 6, 2026. That is the feature’s publication date, rather than a confirmed product-launch date. Its four separate crossover modules support two passive wiring arrangements.
What comes with the DLS RC6.28 component kit?
DLS pairs 6.5-inch coated wood-fibre woofers with 28 mm silk-dome tweeters. The manufacturer lists a 4-ohm impedance, 125-watt RMS rating and 250-watt maximum rating. Woofer fitment figures are a 70 mm mounting depth and 142 mm cutout.
The kit has two woofer low-pass filters and two tweeter high-pass filters in four separate housings.
Two-channel passive or four-channel bi-amp
The manual keeps all four modules in both arrangements:
- Two-channel passive: one channel per side feeds both drivers through their respective filters.
- Four-channel bi-amp: separate channels feed the woofer and tweeter branches through their filters.
Both arrangements use passive filtering. For active operation, DLS requires appropriate active crossover settings before the tweeter’s supplied filter can be omitted.
Put the chosen arrangement on the work order
Before buying an amplifier or approving the installation, ask the shop to identify the intended arrangement and label each channel’s job. Include where the four modules will be secured and accessed, plus the woofer adapters and tweeter mounts the vehicle needs.
That gives you something concrete to compare between quotes. A proposal for two amplifier channels and one for four channels may involve different wiring, setup time and equipment, even when both use the same speaker kit.
For the underlying differences, our passive and active component-speaker crossover guide explains the signal paths and protection responsibilities.
