[@chaeyoungshi]

The 15” model looks very different

[@loudspeaker-solutions]

it's plywood and amplifier is equipped with a toroïdal transformer. boomer is typical for bass only. absorber inside is to keep reverberation of highest frequencies as low as possible. it seems to be a great deal for the price.

[@Techscrews]

it's very good deal for this price tag.

[@MrVincent97133]

thanks for the video , good job ….

2:15 cool, i didn´t know that there is a lamp inside...... xD

Yea 😉

What an aweosme subwoofer!

[@Techscrews]

and surprisingly cheap :)

[@mikedubz5576]

Is this good sounding, does it bump or it clips and no life in its Juice? Thinking of getting 2 of them to Stack my 10 inch rcf art 310-a. Or should a Just get the 15 version? Its for my room of about 10sqm big

[@tbrick4970]

not bad, the woofer looks pretty high quality

[@cassiya100]

It's just a generic China subwoofer found in many active subwoofer boxes such as Atomic Pro.. Tek audio.. Hill audio and many others..They do sound decent but nothing like the top notch branded like QCS..FBT..RCF..Yamaha..etc etc

[@xxg.tester7851]

It's of 12" inch right?

[@Techscrews]

yes, there also have 15 and 18" versions.

[@TechnikToni-Overtribe]

Is the amp a build like class H but with the first Stage beeing Class AB and the secound stage beeing class d cause of the mosfets or is it just that the first stage uses transistors an the sceond one uses mosfets?

[@YetAnotherElectronicsChannel]

Haven’t seen a Class-D amp. Filter inductors were missing. On the transformer u were able to see two voltage rails , +/- 24V and +/- 48V... so could be Class-H

[@falco2855]

Hello, is there a way that you accept Packages? My Hyper X Cloud 2 Gaming headset is broken, the sound only works sometimes, i think its the Cable. Is there a way you could add a Detachable cabble mod to it?

[@Techscrews]

I live in Latvia and shipping both ways cost too much. Just buy soldering kit and do mod.

[@depcz]

Interesting :)...

[@Techscrews]

the 288 euro for this sub is so cheap price :)

1 thing i dont undestand...this sub surround is like most of home and car sub...but other p.a sub surround look different...what is the difference please???

[@Techscrews]

Its very cheap.

[@RediffusionMusic]

I’ve seen professional subs of thousands of dollars using a soft surround like this… all it really enables is the driver to shift more air, this subwoofer will play a lot deeper than a lot of the subs the same size - very apparent when you’re listening to it in person, for what is a 12” sub, the voicing/sound of this sounds more like an 18” - more focused on the low notes, less of the high tight bass.

[@mikedubz5576]

​@@Techscrewswhen you say cheap to own one /buy it due to its cheap price or is it a cheap pole of junk? Please specify

[@Techscrews]

@@mikedubz5576 it's not for PA use, only home parties.

[@timmetjuh070]

Why is there an passive filter?

[@Techscrews]

It's more cheaper.

[@timmetjuh070]

@@Techscrews Hmmm? Whats the use of it? Low cut? Because there is an active filter on the amp right. You can choose the frequentie

[@Techscrews]

@@timmetjuh070 I think, it's for subsonic filter, to save speaker and get more power for effective band, that this sub can play more quality.

[@timmetjuh070]

@@Techscrews Hmm maybe thats it. But a passive filter will reduce power and effeciency tho. I really need to try this sub. You recommend?

[@TechnikToni-Overtribe]

timmetjuh070 The driver is actually the 12-280 as 4W Version which is very good but I would recommend you to try the passive

[@technikundco.5027]

The driver costs only 55€

[@Petermaler66]

Very good driver for only 55€, what a bargain !!!

[@technikundco.5027]

Petermaler66 I dont know the driver but I have a B&C 15BG100 and it is very good but it is expensiver

Technik Und co. Trotzdem nicht weil das nicht der Treiber aus dem Sub ist im Link ist ein 8Ohm chassis und im Achat 112 egal ob passiv oder aktiv ist ein 4ohm chassis was als Ersatzteil 75€ kostet

О, да он фанерный! Я думал - из МДФ ). Думаю, можно взять такой из-за корпуса (фанера!). Потроха нахер выкинуть, и продать от греха подальше. Поставить норм. динамик вместо этого дерьма с полиуретановым подвесом. Воткнуть туда проф. динамик ватт от 500 хотя бы, подходящий под объем корпуса, и будет нормальный саб! За видео лайк, интересно было узнать, что там внутри!
