Scan-Speak Opus

[CptTripps]

Has anyone built the Scan-Speak Opus?

An externally hosted image should be here but it was not working when we last tested it.

I've been looking for a project, and this one just happens to use the two drivers I have left over from my failed "Response 2s" clone project. Looks like a simple crossover and I'll bet the bass is deep and clean.

My only question is if there is a port tube on the hole at the floor, or is that whole cavern the "tube".

Any advise? It looks like it'd be a blast!

It's a tube I think, you can always contact audiocomponents for the exact specs.

I've heard this speaker in a demo-room (@ DIY-shop) but I can't say anything about the sound. The only thing I can say that's it's not bad 😉.

The tweeter is very nice.

The only thing I can say that's it's not bad

So does that mean I'd be wasting my time?

I can find the plans for the speaker about 20 places on the net, but no pictures/reviews to be found.

I can't imagine they'd be THAT bad....could they?

 

[JoeBob]

I don't think he was putting them down when he said they were "not bad", he did afterall have a little 😉 next to them.

 

[CptTripps]

Oh I know...I'm just making sure. =)

I'd hate to spend time/money building them then find out that the wink meant "Boy do these blow a$$"

I'd still like to find some additional pictures somewhere. I'm also waiting for Rolf to respond on if there is a tube there or if it is just a hole in the MDF.

Pending an answer by Rolf...
According to the drawing it's just a hole. (But you obviously have seen the drawing.)

Cheers,
Bas

 

[CptTripps]

That's what I was thinking. Maybe I'll route out the inside and outside a little so I don't get noise from it.

What material do you think this is? I'd been thinking just 3/4 MDF, but that brace may need to be made out of birch plywood. Those edges look WAY too thin to stay together as MDF.

I'm going to go and start building these tonight....I'll let everyone know how it goes.

 

[Taco]

If the speaker sounded dreadful I would remembered it, if it was the best I've ever heard I would remember it too, so it's a decent design which doesn't let you down. 🙂

 

[CptTripps]

I can live with that... Thanks!

Hi
There´s a 145mm pipe at botton, "bassreflexpijp" in
dutch, shown at very botton of drawing 1.

Cheers, JC

There's only two things I can't stand: people who are intolerant of other people's cultures, and the Dutch.

🙂


Thanks!

Cptripps:

I´ve found the Opus on Jan Decker´s website

http://members.home.nl/deckersmoll/

I´m not sure if he got them yet, but he can answer you in english about sound performence. He wrote me some years ago the its sound is relaxed, musical and not very detailed as 9XXX SS and Seas Excell tweeters

BTW: Why your Responce 2S have failed?

Cheers, JC

 

[CptTripps]

I could not get the crossover right and am HORRIBLE at math so it was a lost cause. Nobody seemed to be able to help me.

I'd love to get them so they sound right, but without anyone else making them and helping, it is impossable for me to finish them.

Goldmember?

Mmmm...missed that....JC is right.

 

[CptTripps]

Goldmember?

Yeah, I love that movie...Everything I could find today was in Dutch, so it came to mind....I'm glad someone caught that for the joke that it was, and not thinking that I was Anti-Dutch or something. 🙂

 

[CptTripps]

I got an email back from Jan. Here are the pics of his and the description that he gave me...

I used to have these speakers but sold them to a good friend. I have always been content with the speakers. They have a good stereo-stage, and very nice high's (not sharp). Also the bass is quite good. All in all a good allrounder. My current speakers are i.m.o. better in the mids and highs but not by a great distance.

 

[CptTripps]

And the other pic...

I'm thinking I'll finish mine the same way. I'll bet a coat of laquer ofver the "Stone-Fleck" would look pretty cool.

 

[Bas Horneman]

Yeah, I love that movie

Me too..🙂

Pity goldmember used some German words though...but otherwise ..Mike Myers put down the character pretty darn good.

Cheers,
Bas

Rolph also sent me the following...

We've used MDF, but plywood will do fine as well. There is a port at the bottom, it should have a lenght of 145mm. The sound is tuned to Jazz-combo's and acoustic music, there it performs best.

So there we have it. I've got the cabinet construction under way and will build the crossovers this weekend. I'm hoping to have them done next week...
