  • I made a pair of panel speakers (a.k.a. distributed mode loudspeakers) recently—they sound fantastic, take up almost no space being only slightly away from the wall, look like sleek fabric acoustic panels rather than bookshelf speakers on the wall, and were pretty darn cheap (~$65 for the pair with dual exciters on each). I’m still in the process of hanging them properly as my rear LR, as they’re only 2 ft squares. I want to create a pair of 2 ft × 4.5 ft panels for my front LR which should sound even bigger and fuller, especially after a little EQ magic. Even just a single panel in a room though would be pretty good.

    I also got a baby bass shaker to put under the couch for movie oomph; you could go for a normal sub too if you feel the low end needs more, but try just the panels first.

    I really want to do a writeup of the discoveries I’ve made once I’m done; my background and degree are in audio engineering so I’ve done a lot of research and testing. To start, I recommend using Dayton’s “high roll” exciters, I like their sound better. My panels each have one of these and one of these.

  • I’ll also add, besides the obvious public endangerment, street racers are just soooo fricking loud. Noise ordinances exist for a reason, but even where they don’t, nobody likes being woken up by a bunch of metal death boxes screeeaaaming past their window at 3am. (Near me, it’s a posse of motorbikes. I typed that as motorbiles at first. Heh.)







  • If I understand you correctly, I think “people don’t easily comprehend the significance of increasing orders of magnitude” is a better way to frame it. To use iii’s examples, people perceive a coffee that costs 5 as being 1 unit more than a coffee costing 4. But when comparing two cars costing 40000 and 50000, the human brain tends to just latch on to the most significant digit, and starts to see it the same way: just one unit more.

    Tangentially, given our brains’ difficulty processing large numbers, I wonder if this effect leads to money management skills being worse on average in economies with smaller base currency units, such as the Japanese Yen, Indian Rupee, South Korean Won, or for an extreme case study, the Iranian Rial, which currently exchanges at 49,313 IRR ≈ 1 EUR. When your haircut costs 1200000, a new phone costs 18700000, and a new car costs 1331400000, it’s hard to judge the weight of your decisions. When the slightly nicer car costs 1645200000, it’s near impossible to notice that you just spent your coffee money for an entire year (~5 days a week for 50 weeks) on a moonroof and Apple CarPlay. Not sure if that example is applicable to the average Iranian, but eh.
