Recommendation of speaker elements (2-way, floor-stander)
I am a student, working on a project where I will be building a pair of speakers. (With intentions of learning how a speaker is built and work.)
I have decided on these factors;
- Budget for elements + crossover about $200-250)
(I live in Sweden - Europe-Audio will be my main source.)
I would like use a finished build as inspiration, as I have limited knowledge on designing a crossover, and pairing elements. I have already designed a cabinet (curved sides etc), which will be modified to the right volume and elements. If I had a finished build to work from, I would have the correct dimensions, volumes etc, which would greatly help my design process.
I have found Troels Gravesen's design, using Vifa PL18WO-09-08 + XT25TG30-04 (Vifa PL18WO-), but it seems to have very little information on sound and so on. My question to you is, do you have any other recommendations on elements + crossover, with better value than the Troel's design? Any help would be greatly appreciated! :)
This one worked out well, might exceed your budget by a bit. The EL166 (AKA Mark Audio No6) MA No3 2 way from Blue Planet is a know good as well and should be well under budget. audio-talk :: View topic - EDINGDALE speaker build
There's this one:
I can help you get it to Sweden if you're keen on it. It's a floor standing MTM with a transmission line for the bass units.
Many 6.5" bass/mids 1" tweeter designs should suit your cabinets.
Take at look at the first few links below :
But probably look no further than :
based on :
As both drivers are available at special offer prices from
Europe Audio. £39 for the bass mids and £19 for the tweeters,
I don't think you'll be able to find a cheaper decent combination.

First off, thank you all for the recommendations.
I have pretty much decided on the Amiga model (https://sites.google.com/site/undefinition/diy/amiga), and I was about to order the components today.
Speaker elements and the inductors are no problem, I can order them from Europe-Audio. I am however having some problem with the resistors and capacitors. Only Parts-Express seem to have some of those components, but their shipping cost is $50 for 6 resistors and 6 capacitors, worth a total of $20.
That doesn't seem like a fair deal to me. Does anyone know where I can find corresponding components in Europe, with the same specifications and quality? I have found some of them at Europe-Audio, but I am to unsure that they are identical apart from brand, to actually order them.
The components are (Parts-Express #);
Maybe another solution would be of some kind soul in the USA would be so kind to order those parts from Parts-Express, and send them to Sweden via an cheaper alternative than Fedex, such as USPS. (I would of course pay in advance, through PayPal.)
Any advice would be appreciated!
I can vouch for the Tony Gee LBS design - see www.humblehomemadehifi.com and look under downloads (dont be fooled by the name "humble"...). Drivers are made by Monacor in Germany, so you could almost take a day trip and go and get them.
It will be hard up against your budget, but after finishing a build, I've learned that the electrics and drivers are only 25-33% of the cost of your first build anyway.
I assume you are taking those parts rather too literally
6.80u cross cap - Jantzen cross cap 6.80u 400V - Europe Audio
0.22u cross cap - Jantzen cross cap 0.22u 400V - Europe Audio
8.20u cross cap - Jantzen cross cap 8.20u 400V - Europe Audio
use 4.7 or 5.6 - I'd say 5.6, A 5.1R 5% resistor should not exist ....
CER-10-5.6R - Jantzen ceramic resistor 10W 5% 5.6R - Europe Audio
CER-10-4.7R - Jantzen ceramic resistor 10W 5% 4.7R - Europe Audio
Use 2.2. It will be fine in that circuit position.
CER-10-2.2R - Jantzen ceramic resistor 10W 5% 2.2R - Europe Audio
Wonderful, thank you! I did search some at Europe-Audio, but I was to unsure the components function would be the same. I did also find it quite strange that the only 5.1R resistor was sold by Parts-Express. So there should be no substantial difference if I use a 5.6R resistor instead? BTW, I can see that the resistors you linked to, says 400V, and the original ones from Parts-Express says 250 V. Will this matter?
Seems you can get values in the USA that are not "standard". Like 2R and
8R where the actual standard 5% tolerance values are 2.2R and 8.2R.
Using 5.6R will dull the treble very slightly, room furnishings make far more
difference, so its effectively next to no difference, very unsubstantial.
Higher voltage capacitors are slightly better, both types are way above
the 100V or so you actually need, so no worries here, it will be fine.
