I have a set of alpine type r 6.5" Coxial speakers they should have a set of wires for the two terminals with a cross over in and db restrictor to stop me blowing tweaters set at 12db. Guess what i have not got leads anyone help me or got any surggestions as i loved these speakers but cant wire them up in my new car without the lead!
if they are coaxials they will have the crossover built into the speaker. It will already send the right frequencies to the tweeter and the mids. Not sure of what you mean bya lead coming out. All you have to do is connect your cars speaker wire to them, positive to positive and neg to neg and thats all. You might be thinking of a compenent set or sometimes called seperates, they will have an external crossover and will have a speaker wire coming from the tweeters, but if they are coaxials just plug them in and away you go.
Sorry Well they may not be coxails then they have two sets of terminals on the speakers what i persumed one was for the tweter part of the speaker and other for main cone please correct me if wrong. So if i link direct to both with 100W amp i was scared to blow the tweater like only option i could see was use sperate channel of amp for each like and make sure one always kept very low.
Infinity Kappa's do the same thing. The coaxial speakers use an external crossover. If you lost the crossovers, then they must be replaced. The tweeter will not survive without a crossover. You wanna make your own crossover, its not that difficult. You will need a 4.7 microfarad non-polar electrolytic capacitor and a 0.15 milli-henry coil (iron core, air core I don't care) These parts should be easy to find, any electronics supply should have them. This is a crossover I made for my own truck, the crossovers that came with the tweeters sucked If your serious about making you own let me know, get the parts an I can walk you through on how to assemble them
Do I really need one?????????????? If so why???????????????????? Now you have my curiousity up The first cap is a 5 microfarad the second is a 16 microfarad. The caps are of course inline on the positive speaker wire. The coil has one lead between the caps with the other on the negative speaker wire. The coil is a .125 milli henry. This puts my crossover point at 5000Hz. Not many tweeters would handle being crossed so low, but with an 18dB/octave slope you'd be suprised with what you can get away with For Johnrizla the slope would be 12dB/octave around 6000 Hz.
LOL!!!!!!!!!! A bypass cap, have you not heard of it???? Its been in the small time audiophile arena for years..........well, at least Back in the early 90's......... A bypass cap is a small value poly cap wird in parallel with the electrolytic to make it "act " faster...thereby reducing hysterisis, increasing transient response, and allowing me to say that I have a "faster cap" than you!!!! wel, to be honest, everytime I installed one in all my cutsom x-overs, they seemed to last longer (in HIGH power systems) and "maybe" helped with the tweeters and their transient response.....Its a tuff call.... a bypass cap is onlu a few microfaads, it is tied in parallel with the tweeters electolytic cap, makes it act faster.... I think it works really in a HIGH END system...... But A/B comparisons have never been done on my part....so.....
If you have a copy of Vance Dickason's "The Loudspeaker Design Cookbook" chapter 7 section 85 titled "Capacitors In Crossover Networks" It is recommended that a bypass cap is used for high value non polars, typically values greater than 20 microfarad. Also the recommended bypass would be a polypropylene between 0.1 and 1 micro farad. Dang it I just learned something. Hate that when that happens. So my 16 microfarad cap is close enough to justify a bypass, I'll get on that here pretty soon.
Yep, you best be getin er done..... without that bypas cap, you will be a loser in everything you ever do.... Well, most everything........... Really, thay arent a bad idea, they have never done me wrong........so if I cant fault them, or find that they degrade the sound,,,,,What do they hurt???????
