Hi everyone, i have a fullrange speaker wich sound great but i want to filter the frequency below 100 hz and set a tweeter on it.
Wich crossover frequency should i choose for the tweeter and why and how do i filter the frequency below 100hz.
This is the speaker----> https://www.parts-express.com/tang-band-w3-881sjf-3-full-range-speaker--264-911
Thanks a lot!!!

If your AV receiver has a speaker size setting choose Small and use a subwoofer. You'll never get any real bass out of these. My Arcam allows me to set the low frequency High Pass frequency for the Small satellite speakers between 80 and 130 Hz.
A crossover to filter out the lows at 100 Hz will cost you 2-3 times what the 881 drivers cost you.
And as Viper has said, add a tweeter up high for the pure treble. These Tangband full rangers, though advertised as FullRange, really don't do the high frequencies well enough for my tastes. I use a coil on the Tangband 871 to roll it off at 5000hz and roll in a tweeter in there at 5000hz with a capacitor.

A passive crossover at 100 Hz might not be necessary for this small woofer is down -3dB already at that point and even if you were to build one, you'd need an RLC to flatten impedance peak and one capacitor as high pass which would sum to 24$ for a pair of speakers. The calculation is based on ERSE npe's and dayton audio ferrite inductors and wirewound resistors. That's considerably lower than 2-3 times the price of 881's.
Sure you can do that. But to get enough capacitance(200 mF) in even relatively inexpensive Dayton poly caps to filter out lows, which is what the OP asked, for both channels you are looking at 2-3 times the cost of the 881. I bought my 871 when they were 25 dollars 881 are about the same price.
My 871 in a ported box of about 10 l actually make some sweet sounding bass. Just not much of it and not very low.

I don't see in the opening post that OP has mentioned wanting poly caps in the XO filter. Anyway, poly caps that low and for such application would have been simply money down the drain. Additionally, expense for the inductors can be further reduced by using thinner magnet wire for the impedance network which would reduce the series resistor value by the value of the inductor's dcr. Unfortunately DIYers nowdays are not that much enthusiastic about making things on their own.

But Parts Express has non-polarized electrolytic for $3.50.... for bass as you say probably fine.
Thanks I'll look them up. Solen is breaking me. But I have a ScanSpeak project underway as well and only wanted high quality things in these boxes. So I started buying from Solen. But I have bought parts from them recently for Tangband based projects which is probably unnecessary quality and expense.

I don't know that I'd put the ERSE PulseX above the Audyn Q4 in terms of sound and build quality.
OP- the W3-881 Neo version can play all the way to 20K, with only using a small notch filter. I would use the active HP in a receiver and use the notch filter.

I'm using a 2.1 subwoofer board, but the 2 fullrange channels are also giving bass wich is to much for the small speakers. It distorts the speakers and they go over maximum Xmax. Thats why i want to filter everything below 100hz and for the high tones i would add a tweeter.
But i don't know how. I can use a highpass filter to filter out everything below 100hz but i can't add a tweeter in that way.
I have searching for 3 way crossover but can't find the right one!
Why? This is a 2.1 amp so 1 subwoofer channel and 2 full range channels. The only problem is that below 100hz it will exceed xmax off my speaker on high volume.
Correct me if i'm wrong
It says 2.1 but i can't see any of your output connections at all on this board. A 2.1 would have 3 channels out.
If it does indeed have 3 channels out one (sub) goes to the sub and the other two go to the left and right 2-way crossovers. These go to your tweeters and 881s. The crossover to eliminate frequencies below 100 Hz is a high pass filter and could be as simple as a cap in front of the 881. We told you earlier what this should be. Around 200mF. if you want a tweeter to kick in though it may not be needed, connect the tweeter in parallel with the 881with another capacitor in front of it. Use an online crossover calculator to calculate the value of the capacitor based on the crossover frequency you want the tweeter to kick in at. This system is not going to be amazing sounding no matter what you do .

It's a Breeze style board. There are 3 pairs of holes for speaker wires or terminals at the rear.
@OP, use a crossover calculator to determine capacitor values for high pass, for both the 881 and tweeter.
Also you'll need to measure results to compare.
And you'll probably need a LPAD on the tweeter to reduce levels a little.
