You should use neither xover. Both xover will be so bright (especially with mass market reciever) that the sound will bite your head off. The sibilance will drive you out of the room.

After trying both xover version, I had to completely rework the xover with help a bit of help.

My version of xover will be much more musical and relaxing, not to mention cheaper due to the use of smaller capacitor. If you want, email me for the xover schematic.

While it may be true that a SS receiver may be less suited to this speaker, it is a complete myth that this speaker is overly bright. Don't know how it happened but this sort of misinformation just will not die.

Build the MKI version. Your receiver will easily handle that load with that many watts and the 4ohm rating.

FWIW, I ran my MKI Eros with a SS 60watt amp for over a year and was never bothered by "brightness" of any sort that could be attributed to my amplifier. Now, if you get the driver spacing wrong, or place the speakers on a wood floor with no room treatments, you may have some difficulty taming the clarity of the Scanspeak tweater......

Dear Jeff,

Sibilance is not reduced by room treatment, that is a load of !@$@!$!@$. Only thing that will help is getting the bump @ 5-6k flattened out with a series LCR.
Only problem being that it will require an inductor that is winded by hand (0,022mH). And it will reduce dynamics. But hey Jeff as long as you are happy with your eros, that's all that counts. Have anny stock in partexpress?
Regards,
Ramon

Did I mention sibilance?

"Brightness"_can_ be cured by proper room treatmnets and proper placement. The tragedy is that you're labelling a speaker "bad" because of the way it's set up and the components that drive it. When in reality nothing could be farther from the truth.

Don't know what shame there is in advocating an excellent speaker whose parts can be bought (FYI) from any number of sources on the 'Net? Nor what harm there is in pointing out that because YOU may have an opinion about the "sound" of a speaker, it's NOT necessarily GOSPEL.

Don't think my components are at fault here ;-)
Marantz CD-7 and Electrocompaniet ECI-4.
The speaker is just too bright, not just in my opinion but in those of many. I could also label you as a biased advocate for this speaker. So you stating I am at fault with wrong components or room treatment/placement as you have no clou as to what I have tried, is just ignorance.
I will leave it at that and hope you will enjoy your Eros Speakers, but I certainly will not and will disassemble johnny nr. 5 ;-)

Andy -- feel free to send me your reworked crossover. I've been building a new set of eros and would be happy to measure it for impedance/response and post it for others to enjoy.

One of the problems with the Eros driver combination is the difficulty in taming the 1khz peak in the woofers, while compensating for baffle step rise and still maintaining a tolerable impedance.

What does the impedance profile look like? What are the minimums?

thanks,

WJ

Wayne,

Did you receive the xover?
