Dayton Ultimax 12" Sub-Woofer - Build

[bijinmb]

Amigo,

I was behind a Sub-Woofer build using Dayton Ultimax 12" driver for the past few weeks.

Got time to complete that last week and its ready to take off now.

The driver construction of Ultimax is quiet sturdy and build quality is very good.

The Dayton 1KW Plate AMP (SPA1000) is too powerful to take any domestic challenge IMO.

The plate amp has good features to tweak the driver in all means.

Cabinet volume is approximately: 5.6 Cubic feet vented type.

Front Battle: 1.5" MDF

The cabinet is braced internally to reduce the resonance and the inside wall is damped with bitumen sheet ->12mm Foam ->3mm Woolen Felt (Kinda new experiment this time, which worked out very well).

The driver takes considerable time to break-in i guess. The Bass is soft and really a room shaker! To my surprise all the windows are jerking after raising the level up to its 60+. Even can see tube lights dimming slightly on drum kicks!


Just thought of sharing few images of the build process below.

@ Krell,

The plate amp can take 120 and 240 V AC.

This is my first Sub-Woofer Build so no option to compare at this point.

Super finish. Is it wood veneer or vinyl veneer? Congrats on a terrific build. The milling machine seems to be doing a great service to you guys....
