Hello all, I am looking to build a kit and was hoping for advice.
I was looking into building a speaker kit which would go well in a stereo setup. I am new to DIY speakers, but am technical from PC building and blueprint reading in general. I have family who are good with woodworking also.

My room is 20x25 and 10ft high. I listen to jazz, rock, big band, and blues mostly. I can study enough to build these with some help as I study new things everyday for networking anyways and do fine. I am picking up a couple of books during the process also on speaker building to get a grasp of how the kit I choose was designed. I was more or less wondering what your experiences with these kits may be as their prices aren't the same.

Hi,
For a first build I'd suggest this : https://sites.google.com/site/undefinition/tarkus

Thanks for the reply sreten. I looked up the speaker you suggested. It seems to be geared more towards rock. I do love my rock, but wanted more open jazz and acoustic sound. I listen to more like 70/30 jazz to rock. I will look over this site as I see other setups here also.
If you're stateside....
My Nephila would be fairly simple to build, and do Jazz quite well, as well as rock and others.
Meniscus sells the kit of drivers and xover parts for my design, and the box is a slightly modified Denovo/PE knockdown kit.
Nephila, Bare Bones Kit /Pair
Build thread is also linked from kit page.
Box I used:
Denovo Audio Knock-Down MDF 1.16 cu. ft. Tower Speaker Cabinet
PE Showcase article. They did place first at MWAF this summer:
Nephila | Parts Express Project Gallery
Let me know if you have questions,
Wolf

You might have to look at German forums to find a lot of Visaton info / user impressions. I've tried to get info before, and most discussions seem to trail off into speculation - the English speaking world seems low on personal, practical knowledge.
I honestly can't imagine any of those kits being bad, particularly if you were naturally a careful, methodical person, and got the build spot on.
However, I also recommend a simpler first build...
1) a 2-way speaker is a much easier intro
2) I think there are better ways to do the bass on a 3-way
These kits you reference use enormous, expensive parts for their low crossovers. I looked up just one of the coils, the Mundorf i100 core coil 8.2mH, and see that it goes for £117.43 (that's $250 Australian, $180 US). That's a LOT of the total budget spent on the crossover.
I have a mini DSP, and think it is an excellent alternative, particularly for low crossovers, where parts are expensive, and where room effects are so strong that a 'perfect' speaker is still better with correction.
Unless you have a reason not to do it this way, I'd say you'd get a lot more for four money by going active for the bass, e.g.
https://www.minidsp.com/products/plate-amplifiers/pwr-ice250
...this also plays to your strengths. Instead of a complex cabinet and passive crossover (new territory for you), you could make these simple, and have the complexity in the DSP, which sounds like your forte.

Yeah, the advice of using direct digital ( I hope, in case of connection to an analogue source it would mess the concept of analogue) crossover is good for someone who works with computers.
Scroll down also this site, I'd lean to classic three way 🙄
HEY ! double woofers !! 🙄🙄

You mean good, eh ?

Zaph's ZRT looks very good and uses premium top of the line ScanSpeak drivers.

I built both Suman's ReDiscovery 2 way and the Zaph 2.5 (65L)
If you have access to a drill press, the ReDiscovery is straightforward and an incredible value.
The Zaph 2.5's are life-changing but you will need a large room. Mine are 4 feet from the back wall and I have a 16 foot ceiling (and the rear of the area opens into a stairwell.) Everyone asks where the sub-woofers are hidden.

Thanks everyone for your responses in this. I decided to go with speakerdesignworks aviatrix. It is cheaper, and will be my first kit ever. I am doing the MLTL box design for more low end. The kit should arrive in 3 days and I will begin the cross over then the box from MDF with a veneer. probably some type of zebra-wood or bamboo. Once I have more money, I will finish it to a 5.1 system, then upgrade the towers to the same companies Statements II model which I only hear good things about.
