Default Trompie`s "Statement family" Mains ,Center and Mini Statements.

I hope I`m in the the right section to post my tread regarding more info on my speaker building project.

About 12 years back a bought some Blue Gum tree planks that was cut from huge old trees (older then a 100 years according to town folks that know some of their history). The piece of land was bought for the development of an church so some of them were cut down and processed into planks.

At that time I didn't had any plans for them so now 12 years later I decided it was time to use some of them in my speaker project.

Fortunately for me my wife had no objection to the size of the Statement speakers. I however had to modify my home to accommodate the speakers so a few walls had to go (they were kind of a nuisance anyway) coupled with some other alterations.

This was my first speaker project.The build took me about 2 months to complete for the set of five. I worked 95% of the time alone with some occasional help from my wife/twin brother and friends.I spend quite some time in designing and building jigs so that I was able to do most of the work alone. Should I decide to build a second pair it would be much quicker next time.

The Statements way in at 80 kg each (176 pounds) and the Minis are 41 kg (90 pounds) each.

Most of the pic`s were taken wit my cell phones camera so I do apologize for the poor quality in advance.
I also would like to mention that I`m not fluent in English and that some of the words might not have the meaning that I intended.


I`m very proud to show you my Statement family.

Magnet placement for holding the covers (that I still need to design and make).

I have taken the idea a little further then only on the front of the baffles and added some magnets to the side of each speaker as well to hold the covers in place when I remove them.
The center speakers magnets are on top as I still need to make a dedicated/matching stand/cabinet for the TV and other equipment so the TV on top of the center is only temporarily.

It`s kind of difficult to see the front magnets on this pics.

Default making the curves

Here are some of the jigs that I made and used. This is what I came up all on my own so I hope to inspire some of you to consider a curved speaker build.

The jigs helped me to achieve the "curved" shape that I had in mind.

Default Top panel jig

This is how I made my tops and the jig that I used.

I used a jig saw to get close to the shape that I wanted and then I used my router and jig to do it more precise.

Default Good luck

Its clear that the Statements can play louder for longer with a bit more bass, BUT the Mini`s truly holds their own ground.
I had the Minis as fronts while I finished the Statements and they did not disappoint nor give in at any thing I trough at them.
Simply flawless performance for their class.

DON'T hurry yourself enjoy the experience it will pay of later.

Good luck with your build repeet and thanks for the nice comment.
