| Speaker Spike Philosophy @linnvolk - I agree - accelerometer data would be quite informative.However, when a front-firing 100 lbs subwoofer is resting on springs with limited horizontal stability (because they are not guided by a shaft or control arms), you are not lookin... | |
| Speaker Spike Philosophy @linnvolk - I can see that Accelerometer testing would be helpful. However, your operating assumption, “100 lbs in rigid body mode”, is exactly at issue here. Once you set the sub on springs you reduce horizontal stability significantly and can no... | |
| Speaker Spike Philosophy @ausaudio - At 92 g x 8 ounces mass you are looking at a force equal to a weight of 736 ounces or 46 pounds.It is very possible that a horizontal force directed towards a 100 pound sub, sitting on springs with minimal horizontal stability, moves t... | |
| Speaker Spike Philosophy Pasted from wikipedia:>>>A 12-inch-diameter (300 mm) paper woofer with a peak-to-peak excursion of 0.5 inches at 60 Hz undergoes a maximum acceleration of 92 "g"s.<<<This is an enormous acceleration, and a membrane with a mass of... | |
| Pimping your router My set up:Spectrum broadband cable (200 Mbps) -> Arris Surfboard Modem (up to 1 Gbps) -> Linksys WiFi mesh system (no bandwidth loss when compared to speed of service at modem; note that CAT5 is spec'd at 100 Mbps).This allows for modem, rou... | |
| Any way to listen to wav or high bit files with anything approaching audiophile sound? @ OPMany ways. Get- good Internet service (> 50 Mbps)- good modem (eg Arris Surfboard)- good WiFi (Google or Linksys or similar mesh system)- any components with switching power supplies plugged in a conditioner with HF/digital filters- minimiz... | |
| Point of higher priced streamer? @paulcreed not sure what you mean with 'noisy', but, ime, some systems pick up noise originating from the MacBook wall wart power supply. Good conditioners (Furman, Shunyata in my case) reject this noise entirely. You can also run the MacBook for ... | |
| Point of higher priced streamer? @sangbro For the purpose of playing music via airplay from an iPad to a DAC you don’t need a streamer. Just get a used airport express with digital optical output into your DAC and then you select this airport express as your speaker.Sound will be... | |
| "Musical" subwoofers? Advice please on comparing JL subs @northman Nothing to add to DBA concept, particularly for larger rooms, when you want more than a "sweet spot".I would not discount DSP, though, particularly in a smaller, regular room, and also in particular with speakers minimizing room interact... | |
| why a 75 dollar blue ray smokes all 2k CD players and any turntable??? @bgoeller In a way you make my point. From tens of billions of sensoric bits/signals only a tiny (very, very tiny) portion is actually consciously processed, and an even a smaller portion makes it into memory.Variation and certain patterns of var... | |
| why a 75 dollar blue ray smokes all 2k CD players and any turntable??? Let me offer a thought: Human information processing is highly limited at about 60 bit/sec.Hence, we experience our environment vectorially, i.e., we focus on variation.Variation is not defined as every absolute change, but every change of pattern... | |
| Total bass suck out at 40hz At a speed of sound of ca 330m/sec, a 40 Hz wave length estimates at ca. 8.3 m, half wave = 4.15 m, pretty close to 14 feet.I.e., you experience a text book suck out (cancellation of half wave by reflected half wave of opposite amplitude).As other... | |
| the sound of massed violins in classical orchestral recordings This is really an excellent thread that seems to get the best from the forum. Thanks!My journey to get strings sound like you experience them live: (1) Add power conditioner (Shunyata Hydra alpha). Moderate effect. (2) Eliminate all 'polluting' cl... | |
| Update on Audiogon Member Almarg @ david_ten - This is very sad news. My best wishes to Al and Margaret. It is a delicate matter to identify breakthrough treatment options for late stage patients, but there are potentially significant improvements for mantle cell lymphoma in clin... | |
| Can Room Correction Be Added to an Existing DAC? @ OPTake a look at https://www.stereophile.com/content/music-round-57The Dualcore can be used prior to or post DAC.I‘d strongly recommend a linear power supply. The switching unit that comes with it is a source of noise.I have used this unit for y... |
