Hi!

I have designed speakers of my own using Dayton Audio loudspeakers (tweeter Dayton Audio 1" Reference Shielded Tweeter, Midrange Dayton Audio 4" Reference Full Range Driver and last but not least, Bass Dayton Audio 8" Reference Shielded Woofer). The reason why I picked these speakers was, that these things are good looking and good combination.

I built the box of 19 mm MDF-wood, 120 mm tall (about 126 mm with spikes), 25 mm wide and 40 mm deep. Volume of the box is around 80 litres. Tweeter and mid has small area of the box and it's filled with lamb's wool. Woofer has over 70 litres of space to and there is 4" Aeroport reflexport in the bottom of the box. With this combination of wooferbox, I really had doubts wheather my choise of woofer had enough raw power to use the space.

I also designed Crossovers by myself, they turned out to be 3. order passive crossovers (100Hz/3000Hz). It was very hard to design, because I didn't have any experience of designing crossovers before this. After many, many "beta" versions I could get all together and succeeded to build them.

I jump over of the construction, but I can assure you that quite a few packs of installingbeers were drunk.Click image for larger version

(There is 47" tv in the picture in the picture to represent the size of the speakers)

There They are completely done and it took me 2 years to desing and do all things to this project. I noticed that the guality of bass is very relative to space and acoustics of the room or apartment. The lowest frequency which I have squeesed out with force is 28 Hz. But still, "kickbass" comes pure and accurate. Songs can be player very loud and speakers do not distort. I'm kind of amazed that these worked out so well.

They shall be enough for now, later I'll buy mic and frequency/spl indicator so I can post some graphics here.

These speakers are designed for apartment house-use, so next will be real home-cinema system. Next project contains at least Maelstrom 21" subwoofer and Hypex 8.0 plate amp.

Cheers from Finland!
