Post Subject: The Red-headed Step-DriverPosted by Paul S on: 1/14/2024

Am I the only one who’s (just) noticed that I have not yet specifically mentioned The Loudspeaker’s midrange driver? This seems odd, in view of the fact that this driver is pretty much the beating heart of The Loudspeaker, playing the range from 200 to 1,300 Hz, handling most of the Musical Energy I’m hearing from The Loudspeakers. Did this driver somehow escape my notice? If yes, is this a bad thing? The driver in question is an 18 Sound 10NMBA520 (10”), with a fancy magnet and a shallow, 28g paper cone, and some sort of a built-in feedback loop that is said to keep the impedance nice. As I mentioned, I have been moving the speakers around since I plugged them in, trying to find a permanent spot for them, including moving them up and down on stands of varying heights. I rather dread the vertical exercise, as my version of the Loudspeakers weigh close to 230 lbs. apiece. So far, stands have ranged from3 ½” to 5 1/2”. A while back I found that I liked the sound and the sound effects (“soundstage”) when I stand between the speakers, putting my ears well above all the drivers. Yesterday I discovered that I get similar-but-more-direct sound if I sit on the carpet, putting my ears at about the center of the midrange driver. The electricity was OK, and the electronics were warmed up when I did this, and I was struck by how much Musical Information I was getting from this driver, and how easily and downright comfortably the driver delivered this information! And I immediately determined that I should at least try a taller (10”) stand, to put that driver at ear level when I sit in my beloved bentwood, Poang chair. I’m casting around in my head, trying to come up with a simple stand that will bear the weight and allow sliding around on the carpet. I’ll get back about this if/when I cross that Rubicon.>>
