Question about Lanzar MAX10D Car Subwoofer

1 Answer

WHEN YOU PUSH DOWN EVENLY ON THE SPEAKER ITSELF...IT JUST SUDDENLY GIVES-WAY, WITH A KIND OF POP. DOES THIS MEAN THAT THE WOOFER IS BLOWN??? AND IF SO IS IT POSSIBLE TO REPAIR THIS TYPE OF PROBLEM? I KNOW VERY LITTLE ABOUT CAR AUDIO SYSTEMS, AND HAVE VERY FEW DOLLARS, BUT KNOW MY WAY AROUND A SOLDERING IRON, ETC. IF POSSIBLE I'D LIKE TO REPAIR THESE 3 '10" LANZARS, THAT WERE GIVEN TO ME.

The first thing to do is to check the resistance of the voice coil. Get an ohm meter & place one lead on each of the speaker terminals. If a value of 0 ohms results, or no reading at all, the voice coil is blown.

If you are pressing in, and suddenly gives way, my guess would be that the excursion of the speaker was too grand (common with car stereo, everyone loves bass) and the wires that wrap around the voice coil of the speaker were broken from the speaker inputs.

It is possible to recone the speaker, but by the time you track down a recone kit (highly unlikely that it is even available) you would be rather deep into the project.

Long story short:
check the speaker terminals with an ohm meter. If you get a resistance, they should work with free woofer movement. No resistance = blown woofer.

I assume you mean the Pr-12RX passive? That seems wrong to me, too. Put an ohm meter across the terminals of the horn driver and the woofer seperatly to see which, if either, is blown. If they're OK, look for a bad solder joint on the crossover.

Speaker suddenly emits very loud noise. Have to unplug it.


Bad capacitor(s). Happened to mine too. Opened it up to find 2 completely blown apart, and 1 bulging. Relatively cheap and easy to replace.

Hi i have problems with my subwoofer it wont play it's an alpine 12'' type e with alpine mrp m350 amp. there is light on the amp. how do I find out my subwoofer is blown or what else can be...


ok, your amp is in protect mode. either the speaker wires are crossed and shorting out, your woofer's vioce coils are melted and the speaker is blown or the amp is dead.

to determine if the speakers voice coils are melted, and thus the speaker being blown is the reason for the "protect" light, simply push in the cone of the woofer in gently with your hand. the woofer should move a little more than an inch, without any resistance, before bottoming out. if there feels to be any resistance, like a rubbing or scratching, before the woofer bottoms out, then your voice coils are fried, and you need a new woofer.

I have a problem with my Yamaha HS50M's. When i play a song with a punchy bass line i get a crackling noise but i don't think its coming from the woofers, what can i do to resolve this or does this mean...


First off make certain it's not coming from the amplifer, try listening via headphones. If that is OK switch the speakers. If you find the sound moves to the other channel with the speaker it is the speaker and not the amp. The next thing to do is closley examine the faulty speakers units looking for damage. Still nothing, then with your fingers spaced out over the cone of the woofer (so you apply pressure evenly). Push on the cone gently so it goes in and out. If is scrapes at all you have a cone that is catching. I'm afraid the woofer must be replaced. If it doesn't catch, your next step is to open up the speaker and look around for damage or bad soldering.

Can a kicker cvr be fixed if it is blown if so how


Speaker lesson here. For space and time, I'll not get into certain nomenclature. Working from top to bottom, you have the cone, rubber surround, basket, spider, voic coil former, voice coil, and the magnet. The binding posts are connected to the tensil leads which connect to the spider and the voice coil. As the woofer is positively + and negatively - charged, it creates a magnetic field which moves the woofer up and down. There is a small gap between the magnet and the voice coil and former that's called a magnetic gap. This gap is what helps the speaker to move up and down, and creates the Xmax. The Xmax of the woofer is the maximum linear excursion the woofer can travel without causing permanent damage. With a blown speaker, normally the voice coil and voice coil former have been pushed out of the correct magnetic gap, usually around the top of the magnet. That means that the only way to fix it is to take the woofer completely apart. My suggestion is to just go and spend the money. A blown speaker is a sign of abuse, and voids warranties from the majority of companies out there to include Kicker.

What is a suitable gale gold woofer replacement?


Really does not matter the point is you can rebuild the woofer for less then replacing with a new one but to each his own on this. But as long as its the same size anything would do for this monitor speaker.

I do not mean to sound generic but its true a woofer is a woofer it is what it is sure there are brands out there but they all work basically the same.

All your doing is buying the name.

Thanks please do click the thumbs above to give me a postive rating for my efforts today,

M-Audio StudioPhile DX4 4'' Woofer


The "voice coil" inside the woofer must be rubbing against the "yolk" plate. Meaning = it is mechanically blown(damaged) to a point but electrically intact.
My sugesstion is to take out the damaged woofer and "google" for a mew woofer with the correct impendance and size and mounting holes. If you dont know thw impendance, then you should go with at least 8 ohms. More ohms = less risk of overloading the amp. whick can cause a fire!

Good Luck!!
