At first I was reluctant to answer this question, as I believe in order to do this properly, will cost more than the value of said sub-woofer.
However as nobody else has commented, I will give you an answer on how you can do this.
There are two problems we need to overcome:
The mixer has no further outputs to connect the subwoofer.
The subwoofer has ...
How much money have you got to spend & would you consider replacing the floor entirely with a new one made of solid concrete, not connected to the current walls or floor?
That is not as frivolous a question as it may seem.
Audio separation, especially at low frequencies, can only be achieved by mass & air-gapping.
You could generate a bit of an ...
To answer your question directly there is no way of knowing which one is better, the measurements are lacking. There is no way a Subwoofer will play up to 1700hz. Those specifications are nonsense.
Frequency Range of Speakers
Humans hearing range is between 20 and 20 000 hz. 20 000 hz can be written as 20khz which you will see very often. As you age your ...
It's not ideal, but if you don't use the headphone output on the mixer, just run a stereo 1/4" to rca y-splitter cable to the rca inputs of the subwoofer. Otherwise, I'd have to agree that it would be more trouble/expensive than it is worth.
Are the subwoofer crossover outputs indeed for passive speakers? Or are they intended for active speakers or amplifier?
I would expect an active subwoofer to have the crossover at line level since passive crossovers at speaker level are quite more expensive and lower in quality.
If the crossover outputs are at line level, then you want to route the line ...
There is long history of Transmission line speakers.
Are transmission line enclosures only good for subwoofers?
No, They excel at bass but most are full range speakers.
I have a nice pair of DCM Timewindows, one of the first TL speakers.
They do provide great bass, (That is probably the genesis of the design, to get great bass) as well as crazy good ...
You will find that your current solution will mix the output and you will get mono audio at all speakers. You need to insert a lowpass filter into the circuit between the amplifier and the subwoofer.
Make sure you filter both the left and right signals independently prior to mixing the audio for the subwoofer.
Information on lowpass filters can be found at ...
OK, so it seems that this question is about a consumer-equipment, 5.1 surround sound system with an active-subwoofer.
The sub-woofer has an RCA in, and when connecting to various sources as described will produce a "popping noise" after a period. Period is varying, but can be "reset" by powering off, and powering back on.
The sub-woofer had the RCA ...
4" and 25 W? That's unlikely to reproduce sound below 80 Hz a decent volume, and you're making its job harder by requiring it to reproduce the entire spectrum up to the point where the tweeters can take over.
'normal' subwoofers have diameters of 10" and larger. Then you want a woofer to fill the gap between ~80 Hz and the crossover point with the tweeter.
First of all, you need to find out the technical data for your planned speaker.
This will lists things like fs Qes Qts Sd Vas and many more.
I tried to find this data for the speaker you mention, but I cannot find them. Hence let me give you an example of a branded 4" woofer, click here. Scroll down till you see "Technical Data" then click on "Show all data"...
This makes sense I imagine as the woofers need more power now.
That doesn't make sense because your new woofer although 400W has a sensitivity of 98dB 1W/1m compared to the old one at 95dB. which means it only takes 0.5W to drive the new one as loud as the old one.
It is recommended that the amplifier has a power double the continuous wattage. So your ...
PreSonus has come to the rescue! Check out:
PreSonus MicroStation BT
at your fav search engine. It allows you to connect your mixer to active speakers (studio or pa), as well as your hifi rca input active subwoofer for 2.1 outputs. It even throws bluetooth connection into the mix as well as an extra headphone connection and a volume control.
And no, I am not ...
@Edwin van Mierlo's answer is correct. But if you're in an environment with not too much RF noise, instead of the expensive converter, you can use an XLR to RCA cable from the MIX output on each speaker to the sub.
Low frequency sound is composed of fairly long wavelength pressure waves and can cause noticeable physical vibrations which will also produce the same sound. Your problem is likely that the subwoofer is shaking the floor itself directly which turns your neighbor's ceiling in to a speaker.
If this is the case, your best bet is to provide physical dampening ...
I think the manual is pretty clear. Stereo mixer output into the subwoofer, stereo output from the subwoofer into either active speakers or a stereo power amp with passive speakers. The subwoofer has active crossovers at line level.
