Your right in terms of retail Peter, at least in some cases. That is why I suggest the owner take their great gear to the next level on their own. Not hard to do with some soldering practice and internet training videos.
Folks spend thousands on gear and wire upgrades and this is one way to keep the gear you currently enjoy. Of coarse one will not recoup the cost if they sell it quickly. I did these upgrades in lieu of selling and buying again. I plan to keep this gear for many years.
I still feel putting a $30 cap in a key circuit position in a piece of gear retailing for ten to twenty thousand is a bit unsettling. It is done all the time. I can't tell you how many high dollar speakers use cheap caps and resistors. I am talking from experience as I have removed the crossovers and was floored. The same is true in amps etc...
Yes, the Duelund cost, but so do these high end pieces. |
Simply locate your crossover and see the brand and size caps employed. I don't know the type of crossover, or how complex, used in your Coincident speaker. The cap values are printed on the cap.
Duelund caps are larger as they are oil types. Not sure how much room or where they are placed in your speaker. I removed the crossover from the box of my speaker and built an external crossover box so cap size is not an issue. This improves the sound by removing all the parts from the massive amount of vibrations in the bass cab of the speaker. It also helps by eliminating any interaction with the driver magnets.
Sound improved with the same parts and I took it even further with the upgraded caps.
My previous pair of $10,000 speakers used $15 Chinese caps. Hard to believe really.
If the bass cap is a large value like 50 or 60 uf , I would leave it alone and stick with the mids and highs.
The resistors and inductors used also greatly impact the sound, but the caps, in my experience with Duelund, offer the biggest improvement. Duelund makes great sounding resistors as does Mundorf for very reasonable money. |
I just read Coincident uses metal oxide resistors and they may be Mundorfs and that is good. The inductors also seem to be of good quality based on current builds. The Auric caps are good, but the Duelunds are in a completely different class to be honest. |

A Duelund on the tweeter is the most important place with the mids to place a CAST cap. It would do wonders Charles. For the builder to say he does not like the CAST is, I have to say it, strange and I am being most kind. Read any and all other reviews and they always are rated #1 by a wide margin. In audio, nothing is absolute exempt CAST always being a nice improvement :-)
I figured he would say that, but the CASTs are simply without equal and on your tweeter would be heaven. No way his comment is based on using the latest CAST cap in that position. Oh well, I wish builders were not so closed minded and defensive. Of coarse some are, but many are not.
Tell him I will eat the cap if it does not indeed sound better. Well I suppose it depends how big it is! |
Charles, I think the CAST cap would fit depending on the value. No doubt it would improve the sound, but understand it would cost and it can be hard to break away and go to someplace new. I have done it so often now that I no longer mind or fear the whole process. I have learned a great deal.
My crossovers are also hard wired and many are.
Raytheprinter, I would say the vast majority of speakers selling for $7500 and above use decent sounding and performing crossover parts that can be purchased very cheaply. $30 caps are a norm.
They are usually housed in a speaker cab full of vibrations that hurt the sound. Many have tested this and plotted the improvements. Actually pretty simple to mod a speaker with an external crossover. I purchased custom made wood cabs that match my speakers, upgraded the caps, speaker wire and damped the crossover cab fully with proper deadening material.
The fact is we owners can greatly improve the sound of our existing, highly touted and reviewed gear, with parts like Duelund CAST caps etc... The builder may or may not agree, but no worries as they don't often know as they have either not tried or decided they they cannot afford it. Some don't believe in these boutique caps etc... So they scoff. This scoffing is also prevalent.
I owned Soundlab speakers that came with $30 caps etc...and the owner actually helped me mod the speaker to great effect. I did a host of modifications to the active crossover based on a schematic he made for me. Great guy!
One of my favorite all time speakers are the Silverline Bolero's. They came with $20 crossover caps and the sound was greatly improved with Duelund caps. The builder did not believe in these caps! Ha!
I own another set of speakers that sounded great, but once I opened up the speaker I noticed the tweeters were wired incorrectly. They always sounded good, but a bit dull in the highs. I reversed the wires to the tweeter and bingo - huge improvement. HUGE. I will not mention the company, but they are well known.
My Aesthetix Atlas amp is amazing and a great sounding amp. I noticed the rather mid grade caps employed in key positions and replaced them with with the Duelund CAST caps and the amp now sings so much better in every single way important to the fidelity of the music we love.
One has to be willing to learn, try and perhaps make mistakes along the way. Yes, even Sphile Class A gear can be greatly improved! No, builders don't always think their gear can be improved. |
Yes, the VSF are flat style and may also fit. They are also very good indeed.
Charles, you would need to know the size of the space and cap involved to know for sure regarding fit. Perhaps you can find out the value of the cap needed and look up the physical size and determine if it will fit? Duelund has changed the look of the CAST over the last 5 years so perhaps the builder does not know today? The VSF would also be a big improvement.
Perhaps they won't fit, but I would check it out to be certain. You could also put it in a different spot also with some effort etc....it may require some creativity which can be fun. |
My current speaker project involves nine caps per speaker! Yikes! I wish I only had one. These speakers actually came with some very good parts mixed in with mid grade $30 caps. The crossover is hard wired to boards resting in the woofer chamber. All those caps were rocking with the bass line and that is not ideal.
I replaced 4 caps in each speaker to Mundorf silver, gold and oil caps. The other 4 caps were already Mundorf SGO's. I replaced some Clarity SA caps with the SGO's.
I am intrigued with a speaker that only uses one cap? Interesting indeed. Mine is a three way Nola speaker. Not sure if the Coincident is a two or three way? I assume a three way? My speakers are about 89bd efficient so I bet my crossover is to blame for that. They are wonderful sounding speakers (Viper Reference 1ax's) and only two sets were ever made. The builder has been most helpful in this instance and is sending me some of his special internal speaker wire plus helped me with several questions.
The upgrade is almost done and they are sounding like speakers 10 times the price they cost me. |
Charles, I just finished reading several reviews of your fine speaker. I now remember they are three way with 5 drivers! Amazing how efficient they are with all those drivers? Funny thing is I have always wanted to own a Coincident speaker. My audio buddy has a set of the Total Victory V's. I have listened to them on several occasions and liked them.
I actually make an offer last month on a set of TV 4's , but the offer was declined. So instead, I have decided to make my speakers be all they can be. The results are amazing thus far.
The fact that your speaker has such a simple crossover makes upgrading them very simple indeed. I would be in there looking at the internal wire, cap and resistor. That is a speaker you can keep for many, many years indeed. |
Wow! Buy the best then - get a Duelund CAST! Parts Connection can get the value you need with a big savings. Call/email Chris for a quote. He is running a big sale right now. That's if it fits. These are flat style so I can't imagine why in the top section of the cab one cap would not fit.
So your speakers must use inductors for the most part. Goodness that is most intersting. I will learn more about this approach to speaker design and crossovers. |
jwm,
I bet they would be! It was also more costly for me to upgrade the caps in my 9 cap crossover! |
I just purchased the Mundorf SGO caps for my speaker project and have also used them in preamps. They are simply not near as good as the CAST in every respect. The CAST are far more natural and organic sounding. The SGO caps are good, but sound Hifi compared to the CAST's.
I had to buy 8 caps for my current speaker project so the CAST caps were simply too costly. But only 2, then go for the best!
The CAST copper caps are just amazing and sound good right away without break in. With break in they get even better.
The SGO's are good and surely a nice upgrade, but the CAST, well they are a revelation. |
Charles,
Chris at Parts Connection can order that size for you and will get pricing
from Frederick at Duelund. I forgot to mention that be sure to order the
CAST copper caps for crossover use, not the high voltage 630 v ones
meant for electronics. |
Chris has always gotten back to me when I emailed? Use the email
address on his site and in the subject line mention " attention
Chris". You could also call PC to place an order and ask the person
who answers to get you the size. Lastly, I would also email Frederick
directly at the Duelund site as he is the owner and can also help you. he
also responds promptly based on my experience.
I also suggest you ask if he is offering the same discount on your caps as
offered on the other sizes on his sight. I am pretty sure you will get an
additional discount beyond the 20 percent .
Good luck. |
Round is what I am used to. In terms of mounting I have used these with quality zip ties. You could put five or six of them down in an + pattern and secure with zip ties North/south and East/West.

You can also hot glue right to the speaker. I like the first method the most if you can get your hands in there.
You can also use the first method above and attach to a thin plank of wood first. The 1/4 inch plank could then be glued to the inside of the speaker. |
Charles, not sure why you need any hook up wire? Simply place where the other cap is and use the leads on the cap? This is best. If you need wire as an extension because the cap is going in a different spot, I would use the same wire in your speaker. Get some from the builder.
Your builder uses good quality copper and I would stick with that.
These style caps are not directional. |
I use Mundorf silver, gold lead free solder. 100 grams of it at PC for some $60. Any solder with 4% silver from WBT and Mundorf is fine. I like the Mundorf with silver and gold. |
Congrats and I hope you got a good price. You will be most pleased I am confident. Give it some 100 hours for decent break in. That is a big cap and it will take a little time to hear all that is coming. |
The CAST caps in my tube preamp and hybrid amp have now fully broken in and my music is so beautiful and natural. I was listening today and I could not turn the volume up too high no matter how many clicks I went up on the knob. I don't listen to loud music often, but it was pure enjoyment with peaks of 97-100 db. Smooth, natural, huge and effortless.
I usually listen with peaks in the mid eighties. Words cannot describe the utter beauty and scale of my music after this cap upgrade.
My CD player is next. I will need to learn which caps are most important in my player and that may take some time. All I see are Panasonic caps everywhere and I simply want to upgrade those most important to the signal. |
