Jordan Eikona 2

Those would go well in the barn

Yes, but all the other directions are covered, it wouldn't be far off

Close but not really. The short circuit over the top is just enuff to kill off enuff of the hiQ driver to have nice, not boomy bass.

17’ wide OB

Sweet! A foot wider than my room.

Yeah, it really doesn't take a tall or side gap for a dipole to work if it's wide enough. Way back when in a then neighbor's 7.5 ft high, below grade basement we did a 6 ft high false wall OB for a stereo pair of Altec 515Bs, but while it had a mid-bass, lower mids out to the 500 Hz XO to die for, we ultimately finished it off as a stereo pair of ~150 ft^3 IBs to get plenty of 'sweet' bass once coupled to a ~matching impedance.

I finally got my new system up and running and I couldn't be happier!

I can understand your hesitation about the Eikonas mid-range, I have a pair of the mark 1. They are easy to listen to for long periods.

They look really good. Are the cabinets cut shapes from a sheet of plywood, with a hole in the middle? That would make a very strong and stable cabinet (apologies to UK readers for the unintended political reference). Does it use lots of plywood?

Yes, Its a Baltic Ply translam build. It does use more material then a standard build but it also makes for extremely stiff cabinets. And I love the look of the exposed grains...
The Eikonas 2 are the most natural sounding driver Ive heard to date!

 

[drkingweeb]

hello, are your cabinet plans available?
thanks,
michael s

 

[11opas]

I don't have plans, I just came up with a shape I liked and made sure the volume of the enclosures is correct. Having an odd shape and the cabinet being braced really well, will help with standing waves and maximizing driver output...
I have a MDF plinth (between the monitor and sub) with sticky tack on both sides to help with vibration isolation from the subs...

The Eikona 2s are in sealed cabinets at 5L for volume.
The subwoofers are 40L in volume and are tuned to 25Hz, F3-31Hz, F10-22Hz.

11opas, Beautiful work, congrats!

 

[mkane77g]

These sound very nice with no corrections.

 

[mkane77g]

Measurement. Can't decipher though.

Measurement. Can't decipher though.

What software is it from? How was it taken?

The red line looks like a response plot, it is typical of the driver, and would sound better with eq. It is surprisingly flat, even though it is not level

Andy

 

[mkane77g]

And when I posted the plot above I didn't have a clue as to what I was doing and still don't. After a few more hours pushing buttons, I came up with this. Still in the dark as to how to use this software. Thanks for the reply Andy.

 

[scottjoplin]

More to the point, how do they sound? What frequency is the crossover? You could always EQ them by ear using a tone generator if you feel anything is lacking or too loud

Still in the dark as to how to use this software.

Did you have a look at this video that shows up after a quick search with Google?

YouTube

Place the mic about 1m away from the speaker to measure the speaker itself.

Or

Place the mic at ear level at the place you will be listening them to get the room response.

 

[mkane77g]

they sound fantastic. The woofers are limited to 80Hz, The FR come on @ 160Hz. 4th order BW Lowpass-2nd order Bessel hi-pass.

 

[mkane77g]

Each measured separately, 1.5" away from the face of the Phase plug. Graph overlay is shown. I would appreciate comments, advice from the Gurus out there in DIY land.

 

[RAndyB]

Place the mic about 1m away from the speaker to measure the speaker itself.

Do as perceval suggested - 1 metre (yard) away.

Tell us what software you are using.
Tell us how you are implementing the crossovers.

Then we can help more.

Andy

 

[mkane77g]

thanks, Andy & perceval. Software is REW. I'm using miniDSP HD with there 2x4 HD plug in.

 

[mkane77g]

The second measurement with Steely Dan. First was George Winston. Thanks
