[Just bought a V75 MKII subwoofer and need the manual to set the low pass filter correctly. Would you be able to help me obtain this manual?

=malcho]That was fast indeed! Good I was able to download most manuals and brochures for the existing speakers...

I saw those S-5000's you bought on ebay. Did it say they were mint condition? I would report that seller. Anyway good luck and if the price was what I think it was then you are ahead either way. I am using the 5000's myself and here is a pick of the side and back channels with the 5000's

Because I got my S-5000's at a great price, I will not report the seller. Apart from one blown tweeter they are in good condition. They replaced a pair of S-100 Bs. I am using them with a S-150 AC center, M&K MX 350 sub and a pair of M&K CS 35 surround speakers. I will replace the CS 35 if I can find another pair of 5000s. The 5000s are by far the best M&K speakers I have heard. They are great for home theatre music and video reproduction. You have a great set-up (dream system). Are you running the 5000s with a 5000 M&K sub?

That makes sense, I am running 2 folded horn subs(18 INCH EACH). I am trying some new speakers and if I like them I will sell my 5000's. They will have to blow me away because the 5000's are awesome. I too used to have s-100b's and s-250's, the 5000's are my favorite.

I have attached a manual for this sub in PDF format.

Enjoy!

Oops, looks like someone beat me to the punch...

There is an example with some nice pics of an MX-150 that has the problem woofer on eBay. The forum wouldn't allow me to post the link but the item number is 110156701918.

Mike

Thanks malcho and Mike. Its nice to have such a quick reply.
Makes a newbie like me feel welcome.
all the Best,

Philip

The driver on that sub is labeled as MX350-4TV2. Does that mean that it was used in other subs including the MX350? Is that the driver Chris mentioned earlier?

There is another item on eBay (170136158977) fir just a driver with the same p/n, but different date code and that one does say "Discover Deep Bass". However, this was an engineering reference unit so it might be a mix and match of magnets and cones. Alternatively, the problematic woofers were probably used only over a set period of time.

There are a lot of part numbers to keep track of so I am not sure but I would guess this driver was used in the MX-350. I have also seen people on eBay claim it was. Chris did tell me that the Z-120TV-4 (17022) is a SF driver that was used in the MX-350, 5320 and the 5160 but it may not have been the only one. Chris, feel free to correct me. I am just trying to share the info you gave me to help free up your time.


Yes, from my understanding the woofer with no writing was only used for a limited period of time. It may have been during the SF transition. By the way, I e-mailed that guy selling just the driver a few days ago and asked if I could get my money back if the driver had a problem and he never responded. Looks like he may be trying to dump some garbage. He sure is asking a lot of money for that stuff too.

Actually, what's wrong with these black-domed woofers is worse than what Mike surmised. The construction was to weave the tinsel lead (the braided lead in wire) from the terminal board through the spider and then solder it to the solid core voice coil lead. Most woofers do this inside the cone at its apex. The woofers with no dome printing put the joint on the spider and then covered it with super glue (the black blobs). How these fail is that over time, the continued flexure of the voice coil lead breaks the lead. It's only a matter of time vs use stress vs length of voice coil lead on the spider. The woofers with printing on the dust dome had a change in construction to stop this breakage. So the best way to know you're safe is to get woofers with printed dust domes. The subwoofer on eBay STILL has value in the cabinet and electronics, and certainly the woofers would "get you going".

The reason it's marked MX-350 is because we STARTED out copying the MX-350 woofer with the 17022. When it came in, it was inexpensive enough to use in all of the other models, and became our "low line" driver. But it was used in everything down to the VX-760.

Also, we didn't assemble woofers from scratch in engineering, so the woofer marked engineering reference was purely that - a reference of what we determined was acceptable and approved from the driver manufacturer. If a performance issue occurred, this reference would be used to make sure everything was ok.

Chris

Thanks for the clarification. I will definitely avoid them at all costs!

Mike

So now that the original M&K is out of business, can anyone explain exactly what the difference is between the S-150P's and the professional line version (I can't remember the professional model number) (other than price)?

I have an MX-350. Are you saying that if the woofer is just black with no M&K logo that it is one of these drivers prone to failure over time. If it fails what would it cost to get a replacement driver? Mine is currently between 4 and 5 years old.

The professional model was the 2510PK. I don't know of any difference in specs between the two models. It seems like it was only a price difference.

Mike

I know first hand from Barry that all M&K bass drivers are Eminence, the 350 is the LAB12 and the 5000 is made by Sanyo believe it or not.

Thanks for the info Tony. So, M&K is no longer?

That is mostly correct. Most of them were Eminence and the 5000 is a Sanyo (I found it hard to believe too). Chris told me that KSC and Meiloon also made 12" drivers.

Are you sure the LAB12 is the same driver as in the 350? If so, that would be great news! I am looking for an off-the-shelf replacement.

Mike

Unfortunately, M&K filed Chapter 7 in February of this year. Their assets have been auctioned off including their name and logo which was bought by one of their old European distributors. The new owners are hoping to bring back M&K and make it better than ever (it seems without Ken). We shall see what the future holds.

Mike

I was told the performance of Professional Series MPS 2510PK is supposed to be superior to Home Series S150PK since the tweeter units are slightly different. MPS 2510PK uses all open-back transmission line tweeters while S150PK uses only one.

MPS 2510PK --> 3 x 1" soft-dome ferrofluid open-back transmission line tweeter

S150PK --> 1 x 1" soft-dome ferrofluid open-back transmission line tweeter
+ 2 x 1" soft-dome ferrofluid tweeter

I believe Chris can confirm or clarify the above.

MPS 2510PK --> Ultra Precision Near to Mid-Field Main Monitor, Frequency Response 80Hz - 22kHz +/- 2dB

MPS 2510 --> Precision Near to Mid-Field Main Monitor, Frequency Response 80Hz - 22kHz +/- 2dB

S150PK --> Powered Satellite Speaker, Frequency Response 80Hz - 20kHz +/- 2dB

S150 --> Satellite Speaker, Frequency Response 77Hz - 20kHz +/- 3dB



The above are from M&K printed literature.

You are correct that the MPS2510PK has 3 open back tweeters. I didn't notice that before.

I can't find any mention of what is in the S-150P so that may be an indication that they are indeed different.

Mike

avfans,

Looks like they indeed have different tweeters. Interesting...

Mike

Interesting info. Thanks.

I did some studies and searching for information for M&K S150, S150PK, MPS 2510 and MPS 2510PK before setting up home theater.

I owned S150 before and now use MPS 2510PK. I "feel" and consider the high frequencies from MPS 2510PK are slightly better.

My current system are:
MPS 2510PK x 3 THX pm3
MPS 2525 x 2 THX pm3
MPS 1525 x 2 THX pm3
MPS 5310 x 1 THX pm3
MX-350 x 1 THX Ultra2
MX-70B x 1

Very nice setup. I think you need one more sub though.

Mike

I have 3 K7's in a small room and 2 K-4 Tripole's. These came with the house I bought. I also have the KX10 (8" driver)sub. The sub is not giving me enough bass at all. I was looking on ebay and I found the kx12 which is a single 12" driver in a 15" enclosure. The price seems right for me and the size seems right for my room. Anyone think of something better than this sub for use in a small room. I am just looking at MK speakers casue that what I have and what I like.

M&K speakers are great! Nice bonus that the previous owners left you theirs!

The KX-12 will be better than what you have because it has a larger driver and will move more air but since it has the same 150 Watt amp that the KX-10 has, it may still be a bit small for your room. What are the dimensions of your room? You should also try alternative placement of the sub in different places in the room. Corners typically give you more perceived bass. You may want to run the KX-10 and KX-12 together or even step up to a dual driver 12" model.

Mike

Chris,

I haven't been here in a while and it really makes me glad to see that someone from M&K is here and helping people out. I wish things would not have turned out they way they did and would love to hear the real story as to how and why someday.

I am very invested in M&K speakers and have been a longtime fan. I received my first M&K sub as a gift when I graduated from High School and it is still working at a friend's house today.

My dedicated theater has S -150s and an MX-5000 II
My media room has S-85s and an MX-150THX
My office and bedroom have VX-7 IIs
and my Great room has an MX-700

I do have some questions about the speakers that I currently have.....

On the S-150s, can you tell me a little about the design philosophy around the shape and size? IE, are all the tweeters the same and are they arranged that way as a sort of line array? What is the ideal amount of power to be fed to these speakers (I currently have a 400wpc Crown amp but can they handle more for headroom)? What is the ideal crossover point? Is 80 HZ ideal or can they be set a little higher?

On the MX5000, I am interested to hear why Sanyo woofers were chosen. I was told that these woofers hold up well to current technology. Why did they halt production? Considering there are two drivers in the MX5000, why is the amp only 400 watts when many subs today are 1000-2000 watts?

When I bought my MX5000, there was nothing that came close to it. Did M&K have any plans on the drawing board for larger more powerful subs to compete with the likes of the new JLs and others?

Sorry to inundate with so many questions. Please keep posting here, I really enjoy hearing about your progress and future plans.

Thanks again,
Matt K (MK)
