Note one can use Audiolense with any passive speaker or virtually any loudspeaker for that matter, including surround sound systems.
The 4722’s are fugly looking, but sound huge.

I selected the biamp version and performed a compression driver upgrade, as suggested by user notnyt on the AVSforum. These 2-way JBL 4722 cinema loudspeakers are about as sensitive as one can get, rated at 104 dB SPL at 2.83 volts at one meter. I love high efficiency loudspeakers for their perceived dynamics. AL5 demo can be downloaded and provides the ability to listen to 90 seconds of correction over your system. The XO version (~$500 US) is what I used for this article. The core algorithms have been rewritten along with several enhancements, ( see what’s new in AL5), in which I take full advantage of in this article.Īudiolense is offered in three different versions: 2.0, which offers frequency correction Surround, which offers frequency correction and time alignment of all speakers and includes a basic crossover for bass management XO which includes True Time Domain (TTD) correction that fully synchronizes the first arrival for all frequencies and all speakers involved, plus a fully configurable digital crossover. This is a significant improvement over AL4, which I have written a few blog posts here on CA. Listening sessions and measurements provide feedback to optimize “room correction” and “partial correction.” Filter design verification measurements are provided.Īs a preview, Bernt Rønningsbakk, the author of Audiolense, has really hit it out of the park with his latest version. Followed by frequency and time domain correction, so the frequency response is tonally neutral and the direct sound is arriving at my ears all at the same time. In this article, I walk through the steps of using Audiolense 5.0 (AL5) to biamp my loudspeakers using a linear phase digital crossover.
