Is JBL TR225 any good?

JBL devices are known for their amazing delivery and the JBL TR225 is no exception. It has a transducer which makes it one of the best options for use in the studio.

This is particularly because of the two compression drivers (including a pure titanium diaphragm mounted to a large horn), and the powerful two 15″ Low-frequency transducers.

An important piece of information that you may also need to know is the fact that this is a 2-way speaker. It also has an impressively smooth crossover that is facilitated by the low pass filter in the woofer.


One important point to note about the JBL TR225 is that it is a vintage speaker, and as such might not be the best-sounding speaker for you. However, the speaker still delivers a considerably good sound at a budget-friendly price. Therefore, this might be a last-minute backup speaker studio, concert, or other public address use case.
