Thank you for showing the speaker from the inside. I like such films the most, and thanks to them, users do not have to disassembly their subwoofers. A large magnet, the speaker looks good. How do you rate this subwoofer?

@Techscrews 2 года назад

For $450, you can't expect much. But it's totally in line with the Klipsch sound, boom boom, very powerful.

@tonythedonluciano 2 года назад

It's unfortunate that Klipsch went with a cheaper 2 magnet woofer rather than one large magnet which definitely makes a difference. Regardless though, I'm a Klipsch Sound System owner too.

@steveschwartz9421 Год назад

Multiple, stacked magnets are no more or less effective than one large one. Multiple small round magnets arranged in a donut shape (Focal, Epique), are especially effective when using rare earth neodymium, samarium cobalt, etc.. This woofer is actually surprisingly well built, with an extended length 2 inch diameter voice coil. The magnet is stacked to give it depth allowing it to control the extra excursion. It just isn’t pretty, doesn’t need to be. There’s a specific requirement depending on the design and construction. To a great, almost absolute degree, the size is determined by the application. There are a lot of really BIG magnet speakers on the market that sound like shiz… Check out the Morel line of large voice coil diameter, neodymium configurations that simply bury larger, impressive looking, inferiorsounding subs. For the most part, especially in audio, you get what you pay for.

@Jeffdachefz Год назад

@@steveschwartz9421 yup motor force calculations are different and it's also based on the grade of ferrite and neo along with how the motor is magnetized to get the BL specs of its TS parameters along with how it interacts with the voice coils and soft parts. Its a big balancing act between cone control, excursion, efficiency etc.. bigger magnets with bigger voice coils and stiffer suspension, you can throw a lot of power to before it wakes up and can have much higher capabilities even in a smaller enclosure. meanwhile a medium strength magnet with softer suspension and smaller coil will need less power to get loud but requires a larger enclosure.

Go to mark: 3:19 top left circuit, Do you see the 820 Ohm fried resistor? I do. Common with this sub amp. It is only a 3Watt. Replace it with a 10watt and add wires to move it to a heat sink.

@Pete.across.the.street 2 года назад

That basket looks like it needs some dampening. Does it ring when you hit it? I got 4 of these, they are very boomy stock. If you use minidsp to time align and eq, they are very good. Looks like if I dynomat the basket and add some more bracing it would be even better. But I'm using them for cinema, so I'll probably let them be.

@white_goose9782 2 года назад

@@Techscrews Hm, I can tell for sure that some of the caps have started leaking fluid. But they could be working still, yes. I got a tip for you that I'm using on my R-115SW; buy a smart power-outlet that cuts the power to the sub at night, and when you're not using it. This will spare the amp a lot!

There wasn't anything wrong with your answer either 🤷‍♂️ You just tried to prove your point, which you managed to do. I read the article, and it says that the auto on/off function (on most models) does not save these amps.

@speakerpat 2 года назад

Eh, the amplifier and driver actually look to be pretty good. I think with a better enclosure, the sub would sound much better!

@Techscrews 2 года назад

this is definitely not bad news, what you think should be improved enclosure?

@speakerpat 2 года назад

@@Techscrews I think the subwoofer could benefit from a sealed enclosure or a passive radiator. If that's not the case, the port tuning should be a little different and maybe the enclosure size. But it definitely has to be reinforced more and maybe thicker wood to minimize resonances and even out the frequency response.

@Jeffdachefz Год назад

@@speakerpat 1/4 wave transmission line tuned at the subs FS. Sealed, ported, passive radiators are all garbage in comparison to a proper T-Line for flat response, loudness and accuracy.
