Hi,
Considering how troubled times that we live in are now, I figured someone might want to build a 2 way loudspeaker on a budget of reasonable sound quality that I have done once for a friend of mine. I haven't got access to any measurements right now but I am confident everything is okay with it. It is a sealed cabinet, so it is supposed to be stuffed with polyfiber wadding to a reasonable extent. It was voiced by measurements and listening.
As far as I can remember, general specs would be something like:
Sensitivity: 84dB/2,83V/1m
Impedance: nominally 4 ohm (lower mids); 6 ohm (mid to hf)
Range: 60Hz(-3dB) to 20kHz(0db)

Very nice, Lojzek!
I hadn't really looked at that driver:
WS 17 E - 4 Ohm | Visaton
Easy enough to modify the default project in Boxsim:
Software | Visaton
It looks flatter than the more expensive W170S-4. Plays nicely on simple crossover. What's not to like at £25! A poor man's Peerless 830875.

Thank you Steve. It is a very decent driver for the money and I have much confidence in its build quality, one among few suited optimally to a sealed enclosure.
Could it be this woofer is not a Visaton original, but a somewhat modified & facelifted (originally) Czech made Tesla/ARN 5614?
Hi Lojzek, thank you for these plans. I am embarking on this project as my first build, given the drivers are available cheaply where I am.
I have a query re: the baffle construction - I note it is completely cut through by the woofer hole. Did you cut the hole after glueing the box?

Hi all
After a delay, I was able to finish the speakers a few days ago. A rewarding experience for sure, I'm already considering which direction to head in for the next build.
Many mistakes were made, as will be evident in the pictures, with some overcome and others left as a compromise. I'm confident the next project will turn out to a much higher standard of finish with all I learned here.
The sound has surprised me. In the intended room with a small class D amplifier, they are a thrill.
To those who may view this thread in consideration of this build, I say proceed in confidence of high value in terms of sound quality. In all, these were approximately £150 in materials.
Thanks again Lojzek - this project was just what I needed, and at the right time. I'm glad I took the oft repeated advice to follow plans rather than jump straight in with my own design.

Hello, today I ordered the speakers and filter components and will arrive next week.
Naked boxes are ready a few minutes ago.
This speakers will be my second attempt for a good sounding speakers and I hope will replace with success an Overnight Sensations (first ones).
Lojzek, do you "chanfren" interior edge of the baffle in the midd-bass speaker hole? For me it's too late to perform this operation, boxes are glued, but...
Thank you

that's very nice project!
and a very interesting cheap midbass.
I am very tempted to build it!
for anyone trying to flatten the bass response and extending it slightly lower - this can be done by simply including a NP-cap (about 800 uF) in series with the woofer, after the crossover. see attached hornresp simulation.

A well known technique in closed box. But surely Lojzek, was trying to keep costs down.

yes, I thought that too. and it may even have a more pleasant sound if there is a slight peak around 100 Hz compensating for less lower extension.
thanks for the great thread link!
