Amps
in Home Theater
There is a guy in Woodstock that is selling an emotiva amp, pre amp and sub for sale for 800. Go to atlanta cls under electronics and do a search for oppo. Towards the bottom there is an ad for b & w speakers and emotiva gear, 1900 dollars in Woodstock. He has 2 bundles 2nd is for emotiva gear for 800. I would posts a link but since tablet upgraded I can't find the clipboard. Good luck.

You don’t need the higher voltage rating of the SA, and the CSA uses a newer construction method with better lead
I like those and they are more in line with my budget, I will have to order a pair. Would the solen or maybe another brand at a lower gauge be better than the PE? Not trying to argue just trying to learn from your experience, I don't mind spending more if the SQ is there. But if the PE will work I will get it, a mills resistor and be done with it. Thanks!

My thoughts, again, are spend your money on caps, not inductors. IMO, at gunpoint and blindfolded, you would not be able to distinguish one inductor from another. Others may disagree.
I am new at this but was also looking at clarity SA cap 50uf at 61bucks each. If got these I would have to do other xover upgrades at a later time. Thoughts, suggestions.

you could also get all you need at Parts express.. Dayton 50uF cap, Jantzen .75mH 18awg inductor and the 15ohm Mills resistor
Yea I looked at that but I really want to go with a 12 or 14 gauge coil. I don't think 18 gauge from PE would be that much of an upgrade but then I don't much experience at this. Looking at mundorf mkp and solen 14 gauge coil, thoughts. Thanks!

Friend, that's a .47uF, not a 47uF.
Your right good catch, guess I was excited to see a duelund for 55 bucks. Well have to make a different choice, thanks Deang.

I was using an academy with my chorus II, voices where a little difficult to hear. I tried different surround modes which helped, direct was best. Another thing you can try is to go into speaker settings and turn up the volume on the center channel, also eq if possible.
If it's the speaker itself agree with rebuilding xover or replace with third cornwall or diy cornwall. I built a chorus 1.5 center and love it, I never listen stereo now just 3 across the front. I would use the academy while getting the parts for cornwall/tv stand speaker then sell the academy. You won't regret the up grade, well worth it.
Also agree with a third heresy up front, I think it would be better than your academy. You could use one of your rears to test and see how it sounds.

yes, the schematic is correct and from Magnaplaner...
I got the 50uF auricap from "cranky Dean" many years ago when he was dealing...
😄 That's funny. I've decide to try the duelund jam caps at 55. bucks each. I'll do the rest of the upgrades in a month or 2 and go with a 12 gauge coil, shouldn't be to hard to do since the xover is going to mounted outside the speaker.
The smga crossover is one or only one magnepan does in series, most other magnepan speakers use parallel crossover design. People seem to like the sound of the smga design.

I used an 50uF auricap capactor, solen litz inductor, 14awg .75mH, and mills resistor when I rebuilt mine...
Thanks for posting the diagram! Where did you purchase your parts? If find a coil I like they don't have a cap I want, don't want to paid twice shipping if I don't have to.
Did you replace /remove fuse holder?

They may have used that sized coil deliberately. Might be better to use a better quality coil, but leave it the same size. So, is it 16 or 18?
I wouldn't be afraid to use a 47uF, it's almost within 5%.
I got the values off an xover diagram I found online. That is the only info I found on coil,16 18 guage hand wound coil. ( I wondered the same thing)
Clarity caps received good remarks for the price, looked at duelund Wow out of my price range. I was thinking 2 clarity caps at 51bucks each and 2 solen pro 14 gauge coils about 20 each. Does that look like a good combo for the money? Can't go higher right now but if there is a cheaper combo that would work as well please let me know. Still looking for a good fuse holder, any suggestions. Thanks!

If they were mine, I’d get the Dayton 50uf and another 47uf cap of your choice. Try both to see if you prefer one to the other. To the best of my knowledge, the inductors do not deteriorate over time. I would leave them alone.
Good luck with your project. Photos would be appreciated.
Agree the coils don't deteriorate but I would like to try a bigger gauge coil. Caps are my first concern, on a budget of a hundred give or take, would like to get best bang for the buck now. Xover will be externally mount so experimenting down the road should be easy. I will take pics but not sure how to post, will cross that bridge when I get to it.

50 uf cap and .78mh 16-18 gauge coil
Would like to go hundred or less. Was thinking clarity cap at 51 bucks, value is 47uf. Would the 47 uf make much difference in crossover point? Could only find one cap at 50 uf which is the Dayton audio, all others where at 47 uf.
If I do change out the coil would the solen 14 gauge be a good choice?

There is hot glue over capacitor, makes it hard to read. I will search the web tonight see if I can't find the value I will scape off the glue. Would it be worth it to change the inductor, it's an air core on a plastic reel.
Any suggestions on a fuse holder, the one on the speakers is a cheap clip on. Thanks!

Hope I am not getting in trouble but I have a magnepan question. Bought a pair of smga's I am rebuilding, fixed all the wires yesterday. Tweeter wires where in good shape. Speakers are going to be housed in an oak wood frame I am build out of an old heavy oak door.
Would it be wise to rebuilt crossovers, simple 2 component xover. ( one cap. and inductor) Would like suggestions for component replacement, cap and inductor. Also want to replace fuse holder with a better quality one, any suggestions and where to buy. Thanks!

It sounds like you need more capable speakers for what your trying to do, want bigger louder with more bass, your asking alot out of that model. It should do loud but if you have the bass at +8 you have the wrong speakers, or get a good sub and back off those settings.
I vote for returning if you can and get a more powerful speaker. IMO
Agree! Have or can you try speakers with a different amp/reciever and different source hook up. 2 subs are better one, cls works if you don't mind used, also diy.

Is that good luck with center channel or wive?☺

Once you get it set up get yourself some concert dvd's. You will get to here some good music and see the band, kind of the best of both worlds.

Is it a bad idea to put in wall speakers in an enclosure, I know they are mostly likely IB but could it work. I need a set of mains (L/R) for a system I have been put together and can get a pair cheap.

Of the front three speakers the center is the most important, if you have 3. If no room for a center at least as good as the other two skip the center as people have said, the receiver will send that info to the front L&R. This is better then a center that can't keep up, not hearing voices and other center info makes you miss the most important parts.
Agree! If you need a cabinet for the tv you might be able to build it to house a matching center channel. I build a tv cabinet to match my left and right speakers. If you don't tell the wive she may never know. Of course you would have to get the parts and be able to build the cabinet.
-
Could post some pics of your setup. Front stage pics if possible to see how much space you are working with. If your system is up try setting your receiver to running without a center and see how you like it.

HI, I just bough pair of RP-280f from ebay
Voice coil out of alignment, most likely rubbing center pole or side of housing/magnet. Check other speakers and contact seller for warranty replacement. Don't try to fix yourself contact seller, if he does not help contact eBay. Good luck!

Your receiver should have a setting for running without a center.

Update got these working today after I ordered some replacement caps and those fuse/lamp things. Very loud speakers and not much in the low end! the new titanium diaphragms haven't been broken in yet on the tweeters. So far so good.
I replaced all the caps and noticed one of the caps that should have been 4 micro was a 3.....weird. Bad QC I assume. I put lamp fuses in to assist in saving tweeters in the future in case a bozo mishandles them.
Couple of 12 to 15 inch subs and your good to go. I use to 2 12 inch energy subs and they blend nice with chorus II. Got one at goodwill for 20 bucks and the other for 50 on cls. For music I like them better than my klipsch sw12,s, for HT the klipsch hit harder. Yes there older but if you find some there cheap and built well.

Heresy Speakers Needed

Heresy I's with no upgrades go 400.00 bucks in atlanta, not a bad deal with upgrades. Plus you can sell the old tweeters, just don't wait to long or they will be gone. Good luck
