Dillon Acoustics' Metaphor

[tomcat9]

After searching many plans, I will build the Metaphor from Dillon Acoustics. Before I start I wanted to ask if anyone has heard these, and what they think. I do not design crossovers, so I hope his is as good as he says.

The only thing I plan to change is mine will have a closed box, no port. I will be using a sub-woofer. Has anyone built or heard these?

Sounds an excellent plan. The OW1 is another speaker using
the Hiquophon tweeter with a GR research bass/mid. On Dennis
Murphy's site you can also find details of substituting other
tweeters.

Personally for a good value speaker I can't see the logic in
spending more on the tweeter than the bass/mid unit.

Dillon has a very good reputation. Search the forum in
www.madisound.com

You will find several messages. For a little more money, you should consider the Dillon Egos... in a sealed box, they are very small, would be very attractive for a HT/music system. You can find kits in www.zalytron.com.

In any case, you should be very happy with Dillon's speakers.

Thanks for the 2 replies guys. I am starting to buy my parts. I may not be able to find a 65 uF cap for the crossover. Would a 64 uF be ok, or does it need to be exact? This 65 uF cap is in parallel with the tweeter. Also, I may need to combine two caps to make 65uF. To do this, do I connect the caps in parallel to add their values?

You migh as Dillon or post in the Madisound Forum.

I hope you'll start a page in the wiki and log updates as you go along. I also did a lot of looking for just the right speaker and am still trying to decide between the Dillon ego, the Eros MkII from Wayne J. at speakerbuilder.com or the Hatt MkIII from Tony Gee's humblehomemadehifi.com.
good luck

bradley,

I will need to see what the wiki is. I am new here. Also, I tried to look at the humblehomemadehifi page, but it could not be found.

Al Garay,
I looked at the benniccaps. I think the 65uF they have is not a polypropylene. I am trying to get all polpropylene or better for the best sound quality, especially for the tweeter. Thanks for the suggestion though.


I found this on partsexpress.com
"To add capacitor values, they can be connected to each other in parallel."

Capacitors in parallel add together.

64uf will be absolutely fine instead of 65uF.

A 64uF capacitor with 5% tolerance is much better than 65uF with 10%.

If they are both 10% then describing one as 64 and the other as 65 is pointless.

You could always bypass the the 64uF with a very high quality
1uF capacitor, the result will be better than any 65uF capacitor
you could sensibly afford.

sreten,

You are so right about the tolerances. I overlooked them. I have ordered some Dayton caps that are 10%, and some Solen that are 5%. I may try to use more Solen. I tought about the bypass cap also. I may try that.

Thanks for the info,

I have sealed LCR Metaphors in my HT/music system. They mate up with a sealed 3 cu ft shiva and MurphyBlaster SPCA's in the rear. Geoff did a wonderful job with the Metaphor. The Metaphor sound is a bit more laid back that the more detailed Ego (also a first rate speaker). However, for HT, the Ego's stain at higher HT volumes.

The OWI is fine with Geoff implementation of the 4th to 6th order acoustic 2100 Hz crossover point. I know others prefer the to cross it higher, but the Metaphor's and the Ego's just work well. I think the Peerless HDS benefits from the lower crossover.

Ego vs. Metaphor

Ego
more detailed precise midrange
smaller
less SPL
requires sub
reveals poor recordings with ease

Methphor
All day listening sound
midrange more laid back
lower Hz extension
higher SPL capability without distortion

Bottom line
Metaphor for larger HT/music mixed use
Ego for music/small room HT
Both benefit from a sub

Good Luck, Jim
