TPAM10HTL - like the TPAM10HT, only more.

Designed shortly after the TPAM10HT and is to be regarded as a preferred design of the two if you are scouting for a 26-90Hz sub to use in HT or hi-fi applications.

It does not reach as far down in the deep as the TPAM10HT which can offer a solid 20Hz reproduction, but compensates greatly for this by it's higher sensitivity, greater definition and SPL capacity, all in the same size.

When compared in room the difference in lower frequency cut off is hardly noticeable between the two, the character in favor of the THPAM10HTL is however most definitely noticeable.

The design below is intended for the 10NW64 from B&C, and allows for the driver to be mounted with the cone visible, this is why there is a double baffle, to create the depth required (>100mm) for the drive assembly (magnet).

Simulation input data for Hornresp is included in the picture above, so please feel free to experiment with other drivers, just pay due attention to the mounting depth as stated above, simulations will be provided shortly.

The second top most brace is not dimensioned with regards to its position along the path, but this oversight is not critical, just put it roughly where you see fit.

Material used is 15mm Plywood.
