Now that PS Audio engineer Chris Brunhaver has rebuilt the Infinity IRS woofer sections in Music Room II, tracks of music that once overloaded the room or underwhelmed the listener are back on the table.
Tracks like Deeper by Pete Belasco, When the Party’s Over by Billy Eilish, or Handel’s Organ Concerto Number 3 suddenly make more sense.
Before the woofer change, there was plenty of deep bass but it was more an effect sound than a real live note. Now, the system sends chills up your spine when those notes move both you and the room.
In fact, one of the joys of an upgrade to your audio or video system is the opening of new musical opportunities. If it’s better bass, you start looking through your library for tracks that demonstrate the new prowess. If a new tweeter or speakers with airy extended highs, you search for more thrills in that music.
If you want a few thrills and chills to challenge your system, and have Qobuz, you can access what we listen to by going here.
Have fun and give my apologies to the neighbors.
A very good explanation of bass!
Isn’t it interesting that bass slam and quality comes not from woofers but instead from above?
Here’s what I mean by that. If you take a 3-way system like the IRSV, where the middle frequency drivers reproduce frequencies down to 100Hz, what you find is that bass impact and speed is determined not by the woofer towers, but rather the midrange drivers. Which is why we can accurately evaluate the bass performance of a power amplifier without that amplifier powering the woofers.
This applies not just to big systems like the IRSV. Just about any 3 or 4-way system will work the same way. Listen only to the woofers while music is playing and what you hear on a plucked bass note is little more than a dull thud. There’s no slam or impact to that sloppy thud because the frequencies that give the feeling of speed are much higher than the lower notes.
You can also listen just to the output of a subwoofer and get the same result: whoomp, whoomp, thud, thud.
It’s the upper ranges of bass that give us the impression of a fast woofer.
