Bass manangement on a super low budget

[gasolin75]

Got a cheap subwoofer and it sounds good

Took a basic bass hz test on youtube, i need a little more level at 75-85 hz

My Behringer FBQ800 V2 eq (the cheapest they make) only has 63 and 125 hz i can adjust, which isn't perfect, although 63 hz is close to 75-85hz i wanna see if i can get something cheap to boost 75-85hz by a few db from my subwoofer

My amp is a Mission 778X and if i had a wiim amp i might be able to get it to sound better but i don't, not shure i wanna own one if i could trade my amp with a wiim amp (or get what it costs for it)

I can't use eq on my pc since i also own a tape deck,cdplayer and a turntable

The absolute cheapest way to apply bass management to the subwoofer would probably be @IVX's "iWoofer" platform.

I see a basic iWoofer PCBA available on Taobao for about $20.

Alternatively, you can download the Gerber files online, then order the PCB from JLC, PCBway etc.

An equalizer is not a crossover. It only has outputs for high OR low (not both) and it only cuts by a certain number of dB.

There are subwoofers with "pass-through" crossovers. The output is line-level so for that you need active main speakers or a separate amplifier for the main speakers.

You can get an active crossover for around $100 USD. Again, they are line-level so the volume control has to come before the crossover, and the amplifier after.

NOTE - The ONLY way to get the "point one" channel in movies is with a surround decoder. The most economical way to get that is to buy an AVR, or maybe get a 5.1 channel (or more) soundcard.

I never mention it to be a crossover but it can adjust the bass on my sub and to be fair it does actually has a high pass filter

Im not at all gonna spend 100 usd,100 euros or 100 pounds on some electronic and certainly not an avr

I bought a cheap "used" subwoofer that sounds good but needs a little more adjustments for a smoother bass, if you can call it that

Then what a normal subwoofer has to adjust the bass

I just read the WiiM DSP notes released a few days ago and they don't recommend using their software for sub frequencies. A miniDSP 2x4 would do what you want or maybe one of the cheaper Dayton versions - Parts Express has both but I'd check eBay for the 2x4 first. These would give you a convenient volume control, DSP powerful enough for sub frequencies, execute a proper XO and they'd be downstream from all your sources.

Or get a used Focusrite 2i2 or similar where you can input your analog sources, send them to computer for EQ and XO then back to the Focusrite to feed the amp. If you go this route it'd be better to invest in at least a 4ch device to control the sub separately.

Won't work, what if i listen to my turn table, tape deck or cdplayer ?

What part of "you can input your analog sources" did you not understand...?

 

[gasolin75]

How can i send the signal from something like a focusrite back to the amp or my subwoofer while listen to my turntable + have some bass eq ?

You can't.

This is the most logical setup:

There just that problem that i can't find anything cheap or used that is also cheap, i could have gotten a better sub if i have to spend 100 euros on a dsp,eq unit

TinySine TSA1701 and the programmer for it are like 50€ and very capable, although SigmaStudio is a bit annoying to use
