| vibration control Rok2id... Retired now, but I worked for 40 years on missile guidance systems.The hardware is designed to work under extreme vibration. The shaker used to perform vibration testing shakes the whole factory building when in use. The effect of vibrat... | |
| vibration control Lacee... The purpose of a loudspeaker is to produce vibration (of air). Management of enclosure vibration is perhaps the most important part of speaker enclosure design.But, as Rok2id points out, we are takling about the effect of vibration on the... | |
| vibration control The human ear is a very sensitive instrument. No argument. However, what our ear hears comes out of a loudspeaker. A loudspeaker only responds to voltage. Voltage is measurable. If the voltage (waveform) applied to the speaker is identical, with o... | |
| vibration control Rodman99999... There was no audible or measurable preamp output as a result of the severe vibration environment.What part of "no" do you not understand? | |
| vibration control Rodman99999... I took the trouble to investigate the effect of vibration on solid state electronics.A high gain circuit (phono preamp) was placed in a box along with a speaker, and bombarded with high dB music. There was no audible or measurable e... | |
| vibration control Rok2id... A solid slab of concrete will, because of its mass, minimize transmission of vibration to the floor. A hollow concrete structure "rings". | |
| vibration control Rok2id... The idea of making speaker enclosures out of concrete proved ineffective. Concrete rings like a bell. | |
| Top 10 Jazz recordings ever I doubt you can find one, but the Audio Fidelity label issued the first stereo LP (using 45 degree grooves) and it was the first of several Dukes of Dixieland recordings. The sonics are superb. | |
| Purpose of using same speakers for surround? Not all multichannel music limits the surround channels to ambience. I have TACET CDs of chamber music which assign different instruments to different channels. I realized that I needed to upgrade the surround speakers when the viola had more robu... | |

| A question for Maggie owners Magfan... You are right about the fuse. I just checked my schematic. I was going on memory from several years ago when I rebuilt my crossovers.At work about fifteen years ago I had occasion to look into superfast fuses. These fuses would be locate... | |
| A question for Maggie owners Magfan... The fuse in the MG 1.6 is for the whole speaker; not just the tweeter.A "4 amp" fuse will carry a lot more than 4 amps for brief intervals like music peaks. All fuses are, to a degree, "time delay" fuses. Blow time is a function of curre... | |
| A question for Maggie owners When I was setting up a biamp rig for MG1.6 I discovered that the high end needed a more powerful amp than I had expected. The trick is that I was looking at the amp's ability to swing instantaneous voltage peaks. not at power. Since voltage capab... | |
| A question for Maggie owners Maggies are, first and foremost, planar speakers. The dispersion of sound is quite unlike the typical "point source" speaker. A "line Array" speaker is somewhat similar.You must first decide if you like the planar characteristics. Some do and some... | |
| Transmission Line Bass "everything seems goes to hell just below that point," (100 Hz).That doesn't happen with Maggies, which is why their bass is a lot "better" than you would expect from the specs. My MG1.6 go silent at 40 Hz, but above that the rolloff is perfectly ... |
