[QUOTE="Slo_Ride, post: 8314027, member: 563830"] The Ethos, DSS’s first product, was designed with two goals in mind. Tight articulate bass and the ability to work in small vented enclosures. A stiff high pressure kraft fiber reinforced cone with a multi-layer foam surround is used to accommodate the 32,5mm of one way xmax. To handle the 1,800 watts of recommended power necessary to push the cone to xmax a rugged 3 inch 4 layer flat aluminum wire coil wrapped on a black anodized aluminum former is used. To ensure music is tight and articulate four eight inch true progressive spiders are utilized along with a FEA optimized 50 pound motor structure. FEATURES 1,800 WATT RMS RATED TRIPPLE STACK 8.6 INCH OD MOTOR STRUCTURE WITH BLACK CHROME FINISH FOUR PROGRESSIVE SPIDERS WITH WOVEN TENSIL LEADS NICKEL PLATED PUSH TERMINALS HIGH PRESSURE KRAFT FIBER REINFORCED CONE MULTILAYER FOAM SURROUND WRAP AROUND RUBBER GASKET 3 INCH 4 LAYER FLAT ALUMINUM COIL ON BLACK ANADIZED ALUMINUM FORMER DUAL 1 OR 2 NOMINAL IMPEDANCE VOICE COILS SATIN BLACK CAST ALUMINUM BASKET T/S PARAMETERS Re 3 ohms Le 2.94 Qms 6.19 Qes .845 Qts .74 Fs 23.75 hz Mms 448.6 grams Cms .1 mm/N BL 21.43 t/m Vas 181.85 liters SPL 88.26 1m/1w Xmax 32.5 mm Power 1,800 Watts NOTE: All parameters were extrapolated via a Klippel analyzer using LPM and LSI measurements. The recommended power rating is not a max input power rating. It is the necessary power needed to drive the subwoofer to 32.5mm xmax in a ported enclosure TBA cubic feet tuned to 32 hertz. This rating will vary depending on enclosure size and tuning. Klippel results extrapolated from production samples and may vary without notice. Klippel testing was performed by Redrock Acoustics. ENCLOSURE RECOMMENDATIONS Sealed Volume: TBA System: Q .71 Ported Volume: 5 cft Tuning: 30 hz Port Area: TBA Ripple: 6db F3:25.75 hz NOTE: All volumes are net and do not include port or subwoofer displacement. Enclosures are recommendations only and can be adjusted per the customer’s desired system response. Recommended enclosures do not consider transfer function [/QUOTE]
