Digital Designs DD2515 15'' subwoofer, Dual 2,0 ohm

DD2500-serien subwoofere ble designet for å trekke den høyeste ytelse fra dagens effekt-gale bilstereosystemer. Høyeffekt lydsystemer krever høyeffekts subwoofere som er bygget for å håndtere belastningen. 2500-serien matcher godt til 500-800 Watt forsterkere pr. element.

   We don't subscribe to the Good, Better, Best product model where a person has to buy the top of the line product to access better quality. Every speaker is built to high-end, state of the art standards, designed for specific long term power handling needs. Our lower power handling subs are built with far better materials than the so-called high end subs of the marketing powers.

   The 2500 'a' Series subwoofers were designed to extract the highest performance from today's power crazy car audio systems. High powered sound systems require high power subs that are built to handle the load. The 2500s match up well with the 500-800 Watt RMS amps driving a single woofer, or the 1000-1600 Watt RMS amps driving a pair.

   Optimum performance requires a unique blend of design parameters/materials for these subs to hit hard, sound great and last a long time. The motor uses dual 25mm thick magnets sandwiched between 12mm thick, machined steel plates. Internal cooling vents from our Free Flow Cooling System keep fresh air circulating around the voice coil.

   DD developed a radical new coil design, The RadCoil, for our Z Series subs; a coil with a built-in heat sink and a series of cooling radiators to move heat away from the coil wire and be dissipated through the Free Flow Cooling System. The voice coil uses the same high temperature wire and adhesives as our 9500 Series. The 2.5" voice coil diameter has sufficient surface area to handle the long term heat buildup while low enough in mass to keep high efficiency.

   The surround uses our EROM profile, copied en masse to become an industry wide standard. The EROM design gives long, controlled excursion while keeping the cone diameter as large as possible. This profile also saves mass over the sculpted rubber surrounds and inner tube style surrounds, less mass is louder and faster.

   The cone is our multi-fiber synthetic blend, the same type of fiber used in the highest power handling concert drivers, not punched out from bleach bottle plastic. These special cones are designed for the highest strength with the lowest weight, again, lighter is louder and faster.

   The suspension in a subwoofer takes real abuse, so the 1500 Series uses proven materials from the 35/9500 Series. DD introduced the world to laminated lead wires over 15 years ago. We found that long excursion drivers performed better with the tinsel lead wires sandwiched between spider layers to eliminate lead slap and broken lead wires. The DD spiders are formed with USA made cloth and tinsel-lead in our proprietary tooling. We then trim and laminate the spiders into model specific assemblies in-house. Making longer lasting speakers doesn't happen by accident, it's a methodical and purposeful endeavor.

   We developed the most electrically efficient connections, the Direct Connect, one of the latest DD innovations to be copied the world over. Our 10 gauge power cable provides perfect copper to copper twisted connections. Direct Connect allows virtually any gauge and number of speaker wires to be connected without signal loss.

   The 2500 Series subs are the perfect choice for systems stepping up in long term power requirements while outperforming other brands top-of-the-line subs at a fraction of the cost.

We recommend to allow at least several weeks of playing time to break in DD Woofers, full break in may take many months. DO NOT play subwoofers at max amplifier power in the first couple of days, give the suspensions a chance to loosen up. As the suspension breaks in, the subs will play lower and louder.
   
After you give the woofers a chance to break in (you'll know when this happens because the woofers will be playing lower and louder) you can start to look at port changes to alter the sound to your personal taste and your vehicles acoustic loading conditions.
