MoFi SourcePoint 10 - Review & Measurements by Erin

[xanalog]

I received the following email, after my contact:

Thank you for reaching out.
We are currently taking pre-orders on the upgrade kit, availability is late August/early September. Please feel free to give us a call to order, or click the link below.
I would be happy to extend a onetime extension and let you exchange your pair and purchase a new master series pair if that is something you are interested in.

I took their option #1 (above) and pre-ordered the 'upgrade-kit'.
Total Price: $317.86 (includes tax+free shipping).

What I am also seeing, in the above photo, are port plugs.

Now offering upgraded X overs for the S10. Will it make an audible or measurable difference? Will they offer the upgrade installed in new speakers? Will that exist for other models?

Will they offer the upgrade installed in new speakers?

They do offer master edition finished speakers for a $496 per pair premium ($3,495/pr vs. $2,999/pr):

Will it make an audible or measurable difference?

Probably not, other than the treble adjust switch, unless they changed some filter values at the same time. I'm not familiar enough with the filter design to say if they have or haven't changed it.

 

[Audiotone]

Do it RTFT and this would not be nessecary...

 

[Devnull]

Looking at the website of the pictures of the new xover, the layout is very poorly done. Look at the orientation of the inductors

 

[DMill]

I would be pretty upset spending that kind of money only a year or two ago to find out there is already an upgrade. These speakers were marketed as endgame when they were released.

 

[aschen]

Releasing an upgrade doesn't make the speakers you originally bought any worse.

My view is that is above and beyond normal industry practice of releasing improved products with no upgrade path for earlier adopters. Especially in this case where the upgrade $$ seems completely reasonable, and less than the incremental increase in price for the new versions.

 

[Arindal]

Reduced treble output seems to be aligned with those reviews IIRC.

Have listened to them under different conditions, and interestingly in some rooms, particularly well-damped ones, people might actually wish for enhanced treble. There is an explanation for that, and it is the step up in directivity index inherent to the 10" midwoofer and the transitional band where tweeter kicks in (between 1K and 2K).

Offering a possibility to adjust the tweeter level -1/0/+1dB is exactly the right thing to do in such cases.

Erin thinks the upgrade is worth it, mainly because he thought the original had a tweeter that was a bit too hot. With the new treble/tweeter switch you can change that. The impedance curve has also been changed. The bass range/FR is the same.

End game is purely subjective concept. Two, one can have it for a some extra $, so prior purchasers are not left out at all.

The impedance is flattened by a correction circuit so a tube amp could be engaged without too much trouble. There are some extra parts to pay.

Treble arrangement is usually done by exchange of one resistor.

People who’ve already spent $4k on a pair of speakers can now upgrade to what should’ve been in the box 1 year later for the low low price of just $600. And oh, btw, you have to take apart your speaker to install it? I have a great deal of respect for Andrew Jones and MoFi, but this feels like a money grab to me. Maybe send them to Danny at GSR and get rid of all the cheesy parts in the old crossover? It’s a bad business move imo.

 

[MarkS]

My beef is that there is no explanation of how or why the new crossover is improved, other than the treble switch (which is irrelevant to anyone with PEQ, which anyone spending this much on speakers should have).

 

[RickS]

From Erin’s measurements, the new crossover does at least have some added impedance comp. It also appears the bass has been tuned slightly differently. Perhaps to allow better range for the bungs. Based on this, this upgrade would not excite me as an owner. All of the tweeter options (and more) could be done with eq.

Did not listen to all of Erin’s video so may have missed something. Did anyone else hear something from Erin or elsewhere that would motivate an owner to rip into his nice new speaker to install this crossover upgrade? Unless I have an amp that might be sensitive to the impedance hump, not sure there is a clear benefit/benefits.

 

[MarkS]

Permanently puts me off ever considering their products.

If you have an amp sensitive to the impedance hump, you should spend the money on a new amp.

 

[kyuu]

Yeah, honestly this crossover thing is really weird to me. If you want to do a treble/bass shelf, get a DSP appliance for the same price or less that is way more flexible. Otherwise it just alters the impedance curve? Were there really a bunch of customers asking for this?

 

[jhaider]

FWIW, I’ve heard the OG SP10 a couple times and always thought the treble was a bit wonky. However, there was no such issue with the V10 at Axpona, which I believe has substantially the same MF/HF xover as the new one. Be intetesting to see the overlaid graphs.

"How to Install SourcePoint 10 Master Edition Crossover Upgrade Kit" by Andrew Jones (15minutes):

As an adjunct to this video, and if you are going to go for the SP10 ME mod-kit, I have some optional recommendations:
^ I'd do a cardboard cut-out to cover the driver/cone, during disassembly/assembly (D/A).
^ I'd lay the speaker, on a mat, on it's back during both D/A of drivers.
^ I'd use care putting back the driver/back-panel, since over-torquing may strip the hole threads (in the wood). Speakers are not designed for multiple D/As.

<<Proof?
^ I'd tie a rope to the driver wires, before pulling them out along w/the old cross-overs (through the back panel); so that fishing the new wires to the front is simpler.
^ I'd rather mount the new x-over inside of cabinet (as also shown in above image capture); rather than making the rear panel a "load-bearing point". But I don't know if possible.
^ Gear-heads know to tighten wheel lugs in a cross star pattern, but apparently speaker manufacturers have not learned that trick yet.
^ I notice the new ME rear-panel has a "Serial No" area, but I could not see if there is a stamped SN (which will probably be different than the current SNs on my current SP10s).
How to OCD:
* Hmmm..., should I replace the new "better wires" with even betterER wires?
* Hmmm..., should I twist these "better wires"?
* Hmmm..., should I replace the terminals and solder them instead?
* Hmmm..., should I solder the cables directly to the x-over boards and/or solder them to the driver posts?
