Danley TH118T :

Building on the success of the TH115, the TH118 has a bit more low frequency extension and is slightly more efficient.
If you need a bit more than the TH115 but don’t have room for a larger enclosure, the TH118 is a perfect solution. The TH118 uses the same enclosure as the TH115. TH118 can be installed permanently using a variety of fly-points available on the install version.
The standard sub-solution for many applications.
