Next are some ground plane measurements outside with R-W12D2 to examine the effect of lowering the receivers low pass subwoofer crossover from 200hz down to 40 hz. This shows that my monster room mode between 30 and 40hz makes the spikey horn resonances above 70hz pale somewhat. Main listening position no EQ (brown line). In room measurements loaded with the brand new R-W12D2: Measured ground plane SWS-1223D vs R-W12D2. Easy!Īnyway I wanted to post my experience here as well in case anyone else Down Under wanted to try one of these monsters out. You can easily model any other 12" driver in Hornresp by copying the data in the fields in the top half (this is the enclosure design) and then double clicking on Sd in the bottom section to open the driver T&S specifications.
Here is the slightly adjusted Hornresp input screen for this design. My buddy got two R-W12D2 delivered by the Lifestyle Store for $250 each. These are in plentiful supply locally and are very reasonable. The problem for us Aussies is the cost of the Lab12 locally of course so I modelled a range of Alpine car subs and all look great.

Part 1: This post captures the design and build overview for Cabinet 1.
So after the fun I had with the TPAM10HTL I've been wanting to build a BIG HT tapped horn and landed on the Snider Lab12 design over on.
