RAM STL4 UP

The Awesome RAM STL4

This speaker was designed a little later and should be considered one of the original series

The STL4 (this is a 3D recreation as no pictures exist?) was a huge transmission line, using a pair of Daleford 13 ohm bass units in parallel to drive the line, a Dalesford 8 inch midrange (because we liked the sound of it!), and an Audax fabric dome hf unit.

When we measured it at the GEC Reseach Centre anechoic chamber it had the deepest bass of any speaker they had ever measured, remaining flat to 30HZ before rolling off.

On initial listening, it seemed bass light, until real bass appeared, and showed just how much bass colouration most other speakers have. It's image placement was particularly good and open.

Only a few of these were built and sold (to real enthusiasts!). Another version which we didn't pursue used a single Seas 13 inch bass unit.
