Sundown TEAM-18 D1/D2 18” Subwoofer

The TEAM is the absolutely biggest & meanest subwoofer in our lineup. The 18” model features our custom tooled and patented frame. We only offer the Nightshade v.3 with our custom tooled 18” frame as it is too heavy for the traditional 6-spoke frame to reliably support. Our custom tooled frame series is one of the few ever made that is capable of supporting this monstrous subwoofer. This model is not available in a 10” size as the motor is too large. 

We mate this new platform to a triple stacked 280mm (11.02”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). The TEAM features an enormous 50mm (1.97”) thick top plate to ensure the coil is always well within the magnetic gap. This motor drives a 4" diameter 4-Layer Flat Wire Aluminum Coil with an extremely long winding (nearly 4” long on the 18s) wound on a thick aluminum former to incredible levels of excursion. We use 100% American made voice coils & build each unit in-house here in North Carolina as ordered. 

The TEAM features the longest coil of ANY speaker we have made to date. We leveraged the advantage of the huge motor of the TEAM so we could take advantage of an extremely long 4-layer coil – the 4-layer coil keeps the mass and inductance down while allowing us to use such a long coil for incredible linear x-max while the huge motor allows us to achieve the level of BL we desired. Each TEAM Sundown subwoofer is well over 100 lbs. of pure audio muscle. 

So what is the purpose of the TEAM subwoofer? It was made to absolutely crush music-based classes in SPL competition by taking both linear excursion & thermal power handling well beyond anything else in our line. The enormous 4” voice coil will handle absurd amounts of thermal abuse. They can also be used in day-to-day high powered musical applications as they do have very good sound quality as well – but be warned (!!!) you will need to invite some friends over to help mount them in your enclosure!
