I stopped using the traditional 3 way and now use 2 12db circuits and no crossover on the woofer. The midrange is reduced by about 10db for IMD control. I put a .05 Uh coil in series to the 8 ohm tweeter for phase shift that eliminates cancellations between the mid and tweeter. I put a .3 Uh coil in series to the woofer to eliminate the cancellations between the 8 ohms woofer and mid. This improves efficiency also, and it doesn't really effect crossover. This basic circuit provides the least distortion to the ear. It has the fewest parts, and therefore is the least expensive and easiest to build. I switched from Linkwitz-Riley to Bessel for slightly better fidelity at a little higher cost. End edit.UC Browser SHAREit Appvn

I have found that the crossing over is also a mixing of two sounds. When a sound is played by a 12 inch driver it will have more low frequency than the same sound played by a 2 inch driver. If the crossover point is too high there won’t be enough low tones for male vocals when they lower their voice and they will sound tinny and unnatural.

Bass reflex was the only new technology for a loudspeaker back in 1930 when people had 3 watt amps, and AM radio with 30db signal to noise ratios. AM only broadcasts down to 120hz. FM broadcasts down to 80HZ. It was hard to find the resonant problems with bass reflex when there was no true sub bass at that time. By the sixties the bass reflex lived on in folk lore and kept alive by parts sellers who knew it was a failed technology. https://pnrstatus.vip/

Acoustic suspension was the next logical move. Shrink the enclosure down from a fridge sized monster to less than 3 cubic feet. It worked so well that everybody started to do it. Many of those models had good woofers and some did not. The difference was the stiffness of the cone. Thin paper cones only lasted about 5 years and then they softened because of the sound energy passing through the cone from inside the enclosure to outside the enclosure. (The energy inside the enclosure is = to the energy outside the enclosure). The high pressure inside the enclosure will find a way out if it can and a paper thin cone is an easy way for much of that energy to escape. The cones that were thick and stiff can last over 50 years. Today’s carbon fiber should last even longer.https://sarkariresult.onl/ mobdro 

tenho code25 eu atualizei ele quando eu ligo ele nao aparece mais o logotipo da marschall tem algum problema.ele esta funcionando normal.

ive had a mg30cfx for a couple years now. the amp randomly cuts out every now and then. volume doesnt go over 3.... any ideas??

It's not happening always, but when it does it's frustrating.  Also, sometimes the volume (when it's only cranked up around 2) it tends to get quiter than how louder it suppose to be. Should i bring it back to the shop and ask a repair?

Hi. I recently purchased a DSL40 CR and am wanting the 6 button footswitch so I can use all of the amps capabilities. Is the PEDL 91016 available yet in the US? My local Marshall dealer says that these have been back ordered for months. Currently they are telling me there is a 2 to 3 week shipment delay. What is the availability of these?

Not a lot honestly. I've had a 50 watt Marshall DSL head for about 6 years now, and it's been wonderful.

The thing is, Marshalls do the Marshall sound very well. But people do not have the space to make the Marshall come alive. Even 50 watts is way too loud to cut loose and open it up to a really nice saturated volume. To keep up with the br00tal metalz times, Marshall has been increasing the preamp gain stages. I have 4 preamp tubes in my amp, and it has way too much gain on tap. Preamp gain will always sound fizzy and harsh compared to poweramp gain, and Marshalls produce way too much volume to open up the poweramp to a nice tonal level, especially in the era of excellent PA systems and great microphones.

I think that a lot of folks throw money at the problem, buying independently built amps made with period correct caps and resistors, PTP wiring, etc. But the differences are marginal at best when comparing two identical circuits (mathematically speaking) build with the types of parts used at Marshall vs. NOS stuff by indie builders. I honestly think half of the appeal is placebo effect. Players fool themselves into thinking their indie build JCM800 copy sounds sooooooo much better than a newly made JCM800 from Marshall. They're the same, any difference will come down to the speakers, microphones, PAs, and guitars used.

Hi! I have an issue while trying to transfer dowloaded presets to my Code25. It occures both usb and bluetooth connections.  On a usb connection i click the “amp” icon on a preset, it’s name appears on a Code screen. I push and hold store button on amp, “saved” appears. But then Code becomes freeezed, it does not react on button push etc. when i switch it off and then switch on it works fine, preset available on amp. The same issue appears when i try to transfer presets using Gateway app. What I do wrong?

Hello everyone,,

Hello,

I am experiencing some troubles with the battery of my speaker stockwell that I bought 2 years ago.

I would like to know the contact phone number of the technical service in Valencia (Spain).

Thanks.

Dear all,

I am experiencing some trouble with my Minor II headphones, as they do not connect anymore. Tried to pair them again, but they do not appear on my iPhone (7).... when switching on, the white light constantly flashes to green, but I cannot find any info about a green light.

I'm looking for some good "Shadows" tones like Apache, FBI and so on. Are they available somewhere?

Thanks for Your response, but  i wanted To insist that popping Is not produced by the buttom, it is through The MX 212a speaker's cabinet, i have compared To other amps DSL And don't  have this problem. Please help me..

Hello All,

What cable does someone use to hook up their ipad to a Code 50? it would a lightning to a ???

And why does one need a cable to  hook up to the Code? if the Code is synched via blutooth then anyhting on the APP, such as updates or presets, should also be able to get tot he Code via the blutooth and not need a cable. Could this be a glitch on Marshall's end or  they just never programmed it into the software to do it. Seems like an oversight, no? 

Thanks for any help anyone can give,

Lou

Does anyone know of a good preset that would sound like the song “I’m Alright” by Neil Zaza?

Hi, 

I have had my code 25 for about 6 months and for a while now, everytime I connect my phone and edit in the gateway app the preset freezes and I cannot change anything or change the preset. On the phone it says I am changing but there is no actual changes happening. On the little orange screen on the actual amp it stays on that preset even if I twist the knob to change preset but can still play and change volume.

TodayI was getting sick of it and looked up if there are updates for the amp and there are, which I then went and installed the latest firmware update. But now when I turn on the amp it shows that it's on and shows the preset but stays frozen and will not play sound at all. Is the amp done or can it be fixed?

a month ago I bought my dsl 20hr, and i have an Excessive popping when switching channels  .. it is normal ? please help me...

Hello mates! I just bought the awesome Marshall Code 50. I'm just wondering how you can organize your own presets in a specific order (and in what presets should you store them all), so you may have for example your very own organized preset: Rhythm preset - Lead preset - Clean preset - Crunch preset. 

That being said, can you move factory presets to other spots to organize them at your convenience too?

Thank you mates!

Hi! 

I have had this Super Lead for 18 years or something and haven´t given the age much thought but the other day it just hit me that this has to be a Plexi and therefore it would be nice to maybe get to know what year it's made.
