As for the sound, you are limited only by the quality of the FM tuner in your head unit. If it works good, it will sound good. (You're gonna have to move this to CAR_AUDIO, I guess they finally got a car audio echo established.) :) Jeremy --- * Origin: tH dG o RLt - Deltona, Florida - (407)574-0284 (1:3618/8) --------------- FIDO MESSAGE AREA==> TOPIC: 183 AUDIO Ref: DCB00011 Date: 08/07/96 From: KURT J.

Even -> Hi Kurt, -> How would I go about testing the speaker? I've got an ohm meter. Does it -> include takeing out the speaker? Well, not necessarily. All you really need to do is put the positive pin of the ohm-meter on the positive lead or connector of the speaker and same for the negative and see what the reading is. Actually, if you have the pins reversed I dont' think it will matter much, the resistance is still the same. If you are talking about some kind of 3-way enclosure, then definitely measure the resistance of the whole circuit, not just the woofer, because the passive crossover will add some resistance, too. --- Platinum Xpress/Win/Wildcat5! v2.0GF * Origin: BBS-OHIO * Mentor, Ohio * (216) 951-8938 * Fido Hub (1:157/586) --------------- FIDO MESSAGE AREA==> TOPIC: 183 AUDIO Ref: DCC00000 Date: 08/07/96 From: BONNIE GOODWIN Time: 02:36pm \/To: SEAN DUNBAR (Read 2 times) Subj: Re: AUDIO POLICY CHANGE Hi Sean! -> BG> As of 8/4/96 the BACKSTAT and BACKBONE.NA Fidonet backbone BG> -> adminstrative files have indicated that the CAR_AUDIO echo is now BG> -> officially a backbone echo.

Dolby B 2. Dolby C 3. Dolby HX Pro 4. Dolby Pro-Logic How exactly does Dolby NR reduce noise on the tape? By ear, it seems that I can achieve the same result through a graphic equalizer. Is the sound compromised in any way when NR is on? On another note, will a more precise rotation of music CD result in a richer deeper sound? Some companies are selling these rings that you put around your CDs (which will increase the moment of inertia). One claims that a more precise rotation will result in a deeper bass and less need for error correction (which implies that the everyday CD player doesn't rotate the disc accurately). Another claims that normally, without the rings, the laser reader from the player actually reflects off the sides of the CD and interferes with the reader. With the rings, these reflections are reduced and hence, you'll hear better music. Both of these reasons sound fake to me. Does anybody have any knowledge on how CDs actually work to justify these two arguments? For the same product, they are offering two very distinct reasons as to why I should buy it. Does the CD rotate at different speeds as the laser reader moves toward the outer disc? Is there more data in the outer rim than the inner rim? thanks! --- Maximus/2 3.01 * Origin: * BlueDog BBS * (212) 594-4425 * NYC FileBone Hub (1:278/304) --------------- FIDO MESSAGE AREA==> TOPIC: 183 AUDIO Ref: DCD00001 Date: 08/07/96 From: SEAN DUNBAR Time: 12:26am \/To: JOHN HOLINSWORTH (Read 2 times) Subj: ohms John Holinsworth had the guts to utter the following to All!

A 4 ohm speaker will let the power through twice as easy as an 8 ohm.. 6-8 ohm speakers are typically used in home applications, and 4 ohm speakers usually in car audio.

You will probably get many responses to this message. The total resistance includes the voice coil wire plus impedance relating to capacitive and inductive reactance. These result from the way voice coils, crossover components, and enclosure type change reactive values based on frequency. For example, the inductive impedance of the voice coil rises with frequency. Taking all of these sources of resistance into account produces the ohm value cited by a speaker manufacture. Because of changes with frequency, a nominal(a form of an average value) resistance is chosen. As a rule of thumb, the voice coil resistance plus 25% is a ballpark figure of the nominal value. But this means, of course, that at some frequencies the value is below or above this average. --- Via Silver Xpress V4.3 SW11977 * Origin: BlinkLink - Perceiving is believing! 412-766-0732 (1:129/89)
