MoFi SourcePoint 888 Review and Measurements by Erin

[Robert-Hifi]

I see why you have that impression, but I'd offer two thoughts:

1. On the contour plots the SP888 is overall quite similar if you look at the -6dB point. But if you look at the 0 to -3dB range, the SP888 is a bit more uneven than the KEFs above 1kHz, but it's also a bit "thicker"/wider than the Blade 2 Meta above about 2.5kHz and than the R1 above about 1.3kHz. My guess would be that Erin's assessment of this is based in part on his listening impressions, because those contour plots seem to show that the 888 might sound wider in radiation or might not.

2. The polar globe plots are not normalized. The 888 looks a lot narrower because all the SPL ranges are lower - it has less energy everywhere, not just in the direct and off-axis dispersion areas. Normalization would change the color-coding of those polar plots to reference 0dB, -3dB, -6dB, etc based on the speaker's top measured SPL level rather than an absolute SPL level.

1. I can see that the radiation width flares out just below 3 kHz and between 6 and 7 kHz on the SP888.
It's a bit more jagged than the KEF's, which are smoother. But Erin probably has his reasons to focus on the Contour Plots.

2. The SPL scale of the SP888 is higher at 93 dB and you could take the dark yellow and see it as red if the SPL scale were identical, correct? But even then it looks narrower?
Also strange that Polar Globe Plots of the SP888 aren't as solid red as on the SP8, while the coaxial driver is the same.
Erin did measure the SP888 at his new home and the SP8 at his old home, but that shouldn't have any effect.

I'm waiting for Pierre to get them posted on spinorama.org. I find it more consistent and much easier to compare and contrast them.

Received the 888's last Thursday. Very strange, 4 days to get from Virginia to Oregon, 6 days to get the 275 miles from Portland to here. Still have some refinement to Dirac target curves but am enjoying them very much.

Robert,
MUCH appreciated

I only recently learned that Erin’s graphs aren’t always consistent

Thank you for pointing out Spinorama’s are

Though if Robert-Hifi hadn’t posted, I would not have known Monsieur Pierre is Mr Spinorama.

Spinorama has a very wide range of gear, including some very $$$ … is Pierre responsible for all the data at Spinorama?

It is a database of measurements, collected from a variety of sources. The source is listed for each speaker.

Pierre gets the spinorama data (Klippel measurements) primarily from Erin and Amir and generates the graphs, EQ settings etc.
Other data sources are Audioholics and the manufacturer, but those are lower in quality.

Including … manufacturers - I wonder how many of them - which ones are accurate?

I’d think Neumann would be. But others(?)

I know March tested the Sointuva AWG in a 3rd party Kippel NFS lab in the US for example, so high quality too.

Thank you

There’s a lot more there than I knew

I wanna see how these compare to the Q950s in terms of measurements. since they are both 8 inch coaxial tower speakers with 8 inch bass drivers

If you are willing to wait, more likely will see the Q11 Meta measured and will see how comparable it is to the MoFi. Based on recent KEF measurements, the Q950 does not look to be as good as the MoFi, but is also less than half the price. If Erin's recent Q3 Meta measurements are an indication, the Q11 response will not be as flat as the MoFi either. Erin claims the (high Q) response issues are not audible, so even if the Q950 exhibits them too, may be worth the risk.

Given how new some of these speakers are, waiting is likely to bring more data and perhaps a better deal on them.

Has anyone else noticed that earlier versions of the walnut cabinet were marketed with the black grilles (as shown on Erin's review page), but current revisions only show the walnut cabinet with the white grilles? Maybe they're assuming anyone who wants the black and walnut look will just run them with the grille off, but I'd much prefer the walnut cabinet with the original black grilles.

My demo set that just arrived from audio advisor came with black grills. They look really clean with the black front. I'm tempted to see if they can ship the off-white ones to compare.

Waiting on a replacement pair due to a rattle in one of my low serial number pair at various low frequencies. Probably just a loose nut or something but found that after removing the screws on the connection plate it wouldn't come out. Mofi suggested trying to get in through the front by removing the lower woofer, but that one is stuck in too. Seems like everything must be glued in, which is really bad for repairability.

 

[PGansz]

The speaker's performance is fantastic it just doesn't look very good to me. If I spend 5k I need to want to look at it while using it.

I'm attracted to speakers with driver color that compliments the cabinet, and not these all black faceplates so many companies use. Unfortunately I just can't see myself ever buying these - but that's just my opinion.

It wouldn't make any sense to glue everything in. Maybe if it was a sealed design to keep it airtight.
A rubber gasket would be sufficient in most cases, I think.

I can understand why people don't like their appearance or even find them ugly.
To be honest I find their appearance just "okay", definitely not a good looker.

But I don't know of any other speaker in this price range with the same performance that looks a whole lot better.
Would love to see more speakers with curved cabinets like KEF used to have 20 years ago (IQ90 or Reference 205/2).
