"Creative" throat arrangement for FLH bass horns

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Here are two pictures I received from a friend while he was moving on some old cabinets to new happy owners. It was a pair of rather ratty copies of vintage (1980ies) 2 x 12" bass/lowmid cabinets of a well-known and reputable French PA manufacturer. 

Since it is an obsolete design that has been out of production for a long time, and the arrangement is unlike most of the stuff I have seen, I thought it would be worthwhile to share this with the community.

Before anyone asks, no, there is no plan, no measurements were taken, these had to be and were sold fast.  

The original, genuine cabinets were specced 45-500 Hz (-6dB), 50-400Hz (-3dB). The midrange on top was specced 230 Hz upwards, not sure of the actual x-over frequency. It was a 3-way system. Also consider the two ports in the rear chamber for improved thermal management  

Pretty clever & creative
