More and more customers are asking for a subwoofer where the cone's oscillation is controlled perfectly, reproducing a low bass and mountable in a small cabinet.
These requirements led to the following concept: Bass driver with a very strong magnet and a very stiff and rigid cone, ensuring a controlled oscillation. A unique low bass control is added. The subwoofer is then combined with an amplification module with a very high power output.
The Alcone AC 8 SW4 bass drivers is deployed in the Sub 8. The driver is manufactured to the highest standards, ensuring first class control over the cone through their strong magnets.
The AC 8 SW4 bass driver consists of:
Particularly the strong drive combined with the low bass tuning, turn out a sound quality which is generally only possible with larger sized cabinets. The principle of low tuned subwoofers with extremely strong drive are at the moment being adapted by manufacturers of finished loudspeakers.
The RCM Detonation DT 80, amplifier module is located at the rear of the cabinet. The module features state-of-the-art Class B amplification ensuring enormous power output with top quality sound, fitted in a small cabinet.
Since a 4 Ohm bass driver is used, the entire power of the DT 80 becomes usable the DT 80 delivers - like most amplifier modules - roughly 50% more power on 4 Ohm compared to 8 Ohm). Picture on the left hand side: Frequency response with 100 Hz cutoff (red line: 60 Hz cutoff).
The kit contains: - 1 x Alcone AC 8 SW4 bass driver - 1 x Detonation DT 80 amplifier module - 2 x bass reflex tubes HP70, pointing downwards - 6 allan wood screws 4x25mm - 12 wood screws Pan 4x20 - sealing tape MDM-5 - building instructions
