Life as I see it podcast #13 I got new speakers!


Yes, I got a new system. This time the system is mostly just the speakers. I have ditched my vacuum tubes (gasp) and ton to an active speaker system. A regular system gets a small signal from a source (CD player, computer, etc.), goes to an amplifier, gets sent to the speaker where it is split between the woofer and tweeter and then you hear sound. That is how 99% of all systems work. An active system does it slightly differently. You still get a small signal from a source but you send that to the seekers directly. It is then split into the different frequency ranges. Each driver in the speaker has its own amplifier, amplifying only the frequencies that are given to it. This has a lot of technical advantages, most of them revolving around the ability to have a sharper distinction of the frequencies going to each driver (steeper slope in the crossover) and much better control over the drivers (the amplifiers are directly coupled to the voice coil). The result is a much more dynamic, clearer, and more accurate speaker. Plus, this particular speaker uses Digital Signal Processing (DSP) to correct for some of the inevitable issues and compromises that are involved with every speaker design. I’ve gone from WWII vintage technology to 21st century!


I got a pair of Equator Audio D8 speakers.


It’s a coaxial speaker, much like my long time favorites KEF. It shares the open, wide soundstage and wonderful tonality. It adds fantastic clarity and dynamics. I think this has been a great upgrade. Anyone looking for some kick ass single ended tube amps?
