how are strokers so great?

[maniackilla 10+ year member]

ok ... im wanting to know informatively, how do the strokers produce so much SPL. they have tiny looking mgnets yet hold 1200wrms ?!?!? im wanting 2 15s each in 3cubes after displacement tuned to ~32hz

they look so weak though, im afraid to give these 1200wrms each .... a guy i was talking to on here said his bottoms out in 4 cubes eveyr now and then with 800 watts.

please inform me, theres always mre room for speaker knowledge.

Strokers have an adjustable suspension on them. If your friend bottoms his out, he needs to adjust it a bit. What does he think the metal rod sticking out the front of it is for otherwise?

These are specialty subs, meant for a special purpose. When they are used within the rigid confines of that application (SPL competition), they perform extremely well. The adjustable suspension that allows the sub to be 'dialed in' to the application is just one of its advantages.

The magnets aren't that big of a deal- most of the motor strength is derived from the first slug or so...plus, a wider magnet will be stronger than a longer magnet...

fairly large BL ratings & higer efficiency. amongst lots of other things.

*and they'll gladly take 1200 in the right enclosure.

That's false. The spiders are there to adjust the centering of the suspension, and you do NOT want to adjust them unless you know precisely how much they need to be adjusted.

All that is really for is so you can adjust any offset, it would NOT be changed with different applications. Adjusting it away from on center just increases harmonic distortion...

1200 each? ill be pushing ~2400 total for daily. thanks for all the info you guys //content.invisioncic.com/y282845/emoticons/veryexcited.gif.c26a15f316d23068607f36ddacd7a7ab.gif

Personally I would NOT recommend buying the Stoker. It's a fairly mediocre woofer for musical applications. You can easily get drivers with 2-3x the linear displacement for the same or less money, which is 6-9dB difference in linear output...

i havent found much. most 15s want too little or too overhead power

Then tell me why would you even adjust them? Why ahve it at all, if it only is to add distortion.

That way if the coil was slightly off center, you adjust the dial, and realign it. That's all it is for. That's why CV tells you not to touch it.

Why would the coil be off center and need adjusting? I was under the understanding that the adjustment was for the stiffness of the suspension, to adjust for enclosure size and power input.

I'm not too keen on the Stroker's motor, but if it has a tight gap, then it doesn't take much to misalign the coil.

I'd have to agree, unless you get them cheap.

I must say... they are quite effeciant, and still handle some decent power. But music... nah.. not at a good volume.

They are getting me to MECA finals... but they havent sounded very good getting there //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And yea... very easy to bottom out... extremely easy really. They don't move much... so it doesnt take much to get em to move too far.

Yep. Only about 10mm xmax, about 11mm of linear suspension travel, so they are by no means a high excursion driver. They have a lot of cone area and they are very efficient at higher frequencies, which is what made them great SPL subs in the first place.

Well, there's goes my idea of what that was for Thanks for that knowlage, Warbleed //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
