i want talkback in a 78 and my old external speaker has seen better days . i was thinking about getting a better external speaker and running dual lines back to the radios external speaker and pa jack and putting the resistor and a variable in a speaker . i THOUGHT i was being pretty smart and as i was patting myself on the back for my inginuity (and wondering why NO ONE had ever thought of this) i found this http://www.sparkyscbshack.com/catalo...71/2433932.htm :shock: . this seems to do exactly what i want , just wondering if anyone knows if it sounds decient . i guess if worse came to worse and i got it and didnt like the speaker i could put the guts in another speaker or a kit box and plug what ever speaker i want into it . im not confident enough to go inside my radio and start soldering .

BOOTY MONSTER it be better if you ran it with a 50-100OHM resistor or a Variable 50-100OHM pot...like you said PA and EXT speaker running to the box (build the setup in the box)

just watch it when you have the speaker to close to the mic..

Booty,I use an external talkback box on my 78. I already had a couple of external speakers and hooked this thing up and it works fine.I did not get mine at walcott but did a google search to find a picture of one.
I would not know how to do what lords said. [img][/img]http://www.walcottcb.com/images/pixel_trans I tried to post the picture but don't know how.

weather on or off topic here ? some of the best cb radio speakers I've ever used had nothing to do with cb in the first place , I use a small cube speaker that were sold at Radio shack years ago , I do understand size can be an issue here , but I have heard some cb related speakers that sounded OK , but I have a ear for the plastic walls of those damned things !! IM not a perfectionist when it comes to this , but I do and can appreciate a good ex.speaker on my radio. The one I use is made out of compressed sawdust and it has plenty of watt handling for my cb , it sounds great and it don't rattle or vibrate and the talkback through it it great. No ear piercing, filling rattling trible ! The best of those plastic beasts that I ever heard over the years had the name MIDLAND on it , I see them used on Ebay every now and then , those are good plastic cased speakers.

thanks for responding guys . im looking at a uniden CORSAIR . switch kit ive actually thought about using a high end computer 5.1 center channel speaker by klipsch http://www.klipsch.com/shop/lists/parts.aspx . ive wondered if the tweeters would make the static over bearing but it could be dampaned with tape or a cotton ball . i intendend to put my order in tuesday so i wont be bugging yall too much more lol .
thanks again guys .

is this the correct resistor ?
http://www.radioshack.com/product/in...entPage=family
if it is........
since i want to do it externally i just use 2 1/8 plug jacks....
install ONE resistor across the 2 hot/center conductors comming out the spkr and pa jack......
then connect the speaker to the spkr side normally (ignoring the resistor going to the pa side) ? is this correct ?
if so i could also just unplug the pa plug to turn off the talk back.....correct ???

sorry if i seem anal but i sure dont want to buy this and then kill it . i really appreciate the hand holding guys . it kind of reminds me of learning to do up grades on the computer . i was so afraid of killing it when i added that first stick of ram by myself and then later added that new graphics card (and drivers) . now i build and fix them for friends and family .

Uniden makes a real nice speaker and i also reccommend the Texas Ranger External speaker. I also told someone else that I know Extra class hardcore anti-Cb'er HAM guys that love the audio out of those speakers. AND THEY ARE CHROME AND SHINY TOO!!!
