Re: Improving Cerwin Vega Crossover Capacitors

Postby KA7NIQ » Wed Nov 09, 2011 5:46 am

Just SMALL changes in the tweeter capacitor values of speakers I have owned over the years can have a great effect.

Here is what Dick Olsher has to say about this

The "BBC dip" is in the most sensitive region of hearing (refer to a Fletcher-Munson curve) and very small adjustments in the value of the tweeter capacitor can "trim" the perspective of the soundstage. If the sound is too "polite" and distant for your personal taste, increase C1 to 5.6 uF; if it is too forward and "in your face", drop back to 5.0 uF. Whatever you do, please don't use generic metallized-film polypropylenes like Solen for the C1 tweeter cap.

I strongly recommend Auricap, Hovland Musicap, or North Creek film-and-foil capacitors, with an additional 0.1 or 0.22uF Teflon bypass for the last measure of transparency. Yes, these parts are expensive, but the tweeter cap is the single most important component in your high-fidelity system - more important than interconnects or speaker wires.

Now, he is referring to a DIY pair of speakers he designed for the DIY speaker building community, but I have found his advice applies to most speakers.

The old Klipsch Fortes I owned were just a little too "In Your Face", so I changed the tweeter cap ONLY by about .5 UF and all the forwardness disappeared.

Once I get a schematic or parts list for the VS 150 crossover, and identify the tweeter capacitor, I will order 3 low cost capacitors, one the same value, one .5 uf higher in value, and one .5 uf lower in value, and listen to all 3 of them.
The value that sounds best will be the ones I use.
Once I find the value that is best, then I will splurge on the best quality Cap I can afford.

Cerwin Vega in 1850??

Hm i see that mod doesnt removed this thread yet.
I choose this forum becuse i thinked that all experts here woud help me.

But all i heared was that my CW is completly useless. <And sure if i got the money i would buy like Precision devices PD1850 and build two 1850 horn in the finest plywood. But thats just a dream to afford something like that. And im sorry if i have started different treds. But i do it for i really want too build i SHEAP horn for my crappy/useless CW 188Eb.

Well know i know that my CW`s that i oeiginally was kind of proud of but know when i know that there are useless i dont know what to do with them.

I REALLY HATE that experts cant understand that some people have a VERY limited budget.

maybe i sell them(CW 188EB) and dont give a f.ck that my dream to build a pair of horn that will fitt my useless/scrappy elements in.
If the CW 188Eb are so useless then WHY did CW build them and put them in foldedhorn

I have really lost faith of my self that i can build something or even care about what use to be my hobby. i was really knocked down HARD by the experts here, that i have hoped to really help a newbie.

But now i know that i suck on speakers so too the grade that i wonder to completly give up my ambitions too build something like a horn/box...

Well Well thats it, this isnt` NOT a attack to any person here, i have full respect for all the people that really knows how it would be.

Sorry for my poor english(are useless to write in english too.

Well know i dont give a shit to search anymore(i mean why would i care when the element i planned to use are f..ing useless....!

anyway know my lust to experement with speakers are completly lost know...!



And yeay sure a maybe started too f..ing new treds for the same questing about my crap bass.



Anyway thanks for the help.i have learned something in this forum atleast. I think/ed it`s really interesting too read others projects.
I mean sawing all the parts necessery for like a 1850 with a usual saw is in my (dont count) opinium really cool.

Guess i have make my self this forums HATE project !!

But f.ck all i really wanted was advice from people that knows how to do to building soma really kick ass horns/boxes.

Thanks for make me realist that i really suck.

If u read this shit i hope i make laugh atleast...

Best regards Mikael thanks for the help.

And YES i going to sell my trash/scrap CW 188EB if any one is as stupid as me, and planning to build some horn.

The fact that CW 188EB is BUILD for horn seems doesnt count,

Sorry if i take your time, but f.ck i really in my entusiasm i really hoped thatthis would be good. but my plans was crushed.

Need receiver recommendations to power a pair of Cerwin Vega Re-38s

I've been looking to build myself a decent sound system for a while now, and since I've recently aquired (free of charge) a pair of decent speakers (Cerwin Vega Re-38s), I'd like to put them to use sooner rather than later.

Now, I haven't been able to find any information about these speakers at all on the net, so all I can say is that they are big and loud. A little TOO big and loud for my purposes, but hey, the price was right.

Anyways, I need some recommendations on what kind of a reciever is needed to power these beasts. Also recommendations on rear and possibly center channel speakers, and maybe a sub (do I really need one?) to round out the combo.

The small amount of infomation I have found is a small sticker on the back marked "4 ohms, 2.5amps" and a website claiming 400 watts per speaker (1000 watts peak). I know that my near-antique RCA reciever would probably not be up to the task, and I want surround sound anyways.

If it matters, this set up will probably be used for movies more than music. Though being in college, in an apartment with no neighbors, it's nice to be able to crank up the tunes once in a while too (and between me and my roommates, we listen to just about every genre under the sun, from country to techno).

Thoughts?

edit: I forgot about budget. There is no set limit really, as its simply a matter of how long I have to save up to buy something, but being a college student cheaper is ALWAYS better. If I could get a decent reciever and rear speakers for $600-$800 I'd be happy. If I could do it for $400 I'd be thrilled -- View image here: http://episteme.arstechnica.com/groupee_common/emoticons/icon_biggrin.gif --
