Monday, May 6th, 2024 - Oklahoma City, OK - DD AUDIO®, a manufacturer of high-quality mobile audio products is proud to introduce the 1506 “A” revision. The 6.5” subwoofer has become increasingly popular as a way to give big bass sound in tight spaces by recreating the force of larger subs with an array of smaller ones. There are many choices when shopping for a 6.5”, but if you want to skip the rest and get the best, the 1506A is the apex. Following in the footsteps of the larger 9900C, 9500L, and 2508G, the 1506A revision completes the arc, not with a whimper, but with a bang, ushering in a new era for these made by hand, in the heartland, subwoofers. Reviewing the full feature list on the 1506 page should make it clear why this little 6.5” sub is the finest performing in its 750w RMS class, but it’s the two main improvements to the USA Made line which can now be found on the 1506A that deserve special attention.
The much discussed heatsink caught the attention of enthusiasts everywhere with its sharp looks and integrated logo carved right into the high grade aluminum, but this addition has been about much more than just looks. The heatsink is a dual stage with the back plate being stage two. Stage one is the cylindrical aluminum tube insert conducting heat away from the soft components and high-temp glues, through the Free Flow Cooling System to the back plate (stage two) where it is expelled. This advanced thermal transfer engineering significantly improves the performance for longer and louder play.
The other big feature that got people talking is the Iron Cloth Spider System. No, they are not made of iron! That said, it’s not just a clever name. The 100% USA Made spiders use a new resin reinforced material that is so tough the laser cutter DD has long used for cutting them to size had to be upgraded to one that could cut 2mm thick steel. The name started in the shop, but as the new spider’s reputation for strength and longevity in early models began to spread, Iron Cloth was officially adopted. To control the moving mass of the 1506A, the spider diameter was made for long excursion capability with as much landing as was possible: 5.75” across. Again, this is the same role profile you can find on the legendary 9500, with 4 progressive rolls, all made from the same dual layer Iron Cloth.
