SEAS KingRo4y MK3 Kit

[Gremlins]

Nice
The best best best moment of this journey IS when you gonna fire them UP, these are going to blow you away on a different level of hifi..

Some progress made! Now it is actually possible to see that it will be a loudspeaker after all!

Now it is time for gluing it all together. Hoping to get that done later in the week. Fingers Crossed!!

Looking good. I wish I had known about that pre-coloured mdf before I made mine. I used a similar sound deadening material but I had to install it after the assembly and paint job. I also I looked at the seas KingRo4y MK2 instructions and they used some filler material inside each chamber so I did to, not sure if that was a mistake or not.
I think there might be a cabinet rebuild in my future.

Would be interested in building a KingRo4 clone but not using Seas and Hypex but Perless/ SB drivers and MiniDSP 2x4HD can someone help I love the concept of KingRoy fullrange thast not a Foor stander I dont mind a FAST too

Easily, with any coaxial mid-tweeter (like from KEF, Sica, TangBand) and any decent woofers.
But you must take measurements and learn to do setting for minidsp. I recommend using HypexFAs and just mofify KingROY settings. I am using both in different projects.

 

[diyhobby]

Any idea how to convert Hypex dsp file to Minidsp 2x4hd

 

[Mister.Mole]

Manually. Open the file in Hypex Filter Designer and note down all the filters.

Should be doable in 30 minutes. Don't use the graph view but the block view.

 

[Gremlins]

That would look like, but not sound like ...

 

[Mister.Mole]

Why not? Are the biquads in the mini dsp doing something else with the values? I think this would be really weird. Here is one biquad from hypex for KingRo4y:

BoostCut, 7635,32 Hz, Q 3,00, -2,21 dB

I would have thought this should mathematically be the same?

If not one would need to get both and either measure acoustically or electrically to get the same output.

 

[somebodyelse]

IIRC from converting the minidsp settings to hypex for lxmini it should work. They use the same Q definition. The filter type names are different though, so make sure you use the right ones, and check the frequency response plots match as a final check.

 

[Gremlins]

The hypex filter values are made for the seas speakers
Changing speakers will not match

 

[Mister.Mole]

Uhh, I missed that part. With other drivers this is a completly new box. You cannot reuse the values at all. They are very driver specific.

 

[Gremlins]

Diyhobby would like to clone kindroy with SB and peerless speakers and getting the values of hypex for another unit: m'y answer is it can "look like" ( ie clone) but will sound like

Values are to aligner specifics of selected speakers, changing them with as they have different values will not sound like a kingroy

 

[Murkas]

Some progress. Now I have 2 boxes! They turned out nicer than expected - even after some very light sanding.

Next step is some felt and filling. After that I will be sanding and then treating the surface with some Rubio Monocoat.

 

[Murkas]

Done!

What: Seas KINGRO4Y
Drivers: C18EN002/A och L26RO4Y2
Material: Black MDF
Amps: Hypex FA503
Finish: Rubio Monocoat Plus 2C Black

They sound promising

 

[Gremlins]

Very nice, contrats
You now have speakers that are basicaly the best that sound reproduction can offer in a living room, period

I would have the right speaker a little less close to wall, also hide a little better these câbles

Lets Rock

Thanks!
Believe me - I hate visible cables so that will be fixed
Will also build some nice stands.
