This speakers have some similarities to my DXT-MON. same concept, small woofer with wave guided tweeter. only difference: simpler cabinet and lack of passive radiator.
bass would become "papery"
Imagine someone selling a complete kit for 500€ after fixing the resonances.Looking at this price and performance, speaker manufacturers are starting to have some explaining to do.
You seem to have a chicken on the loose too.View attachment 366452
The other day my cat became papery.

How do you explain a loose chicken and a papery cat in one day?You seem to have a chicken on the loose too.
I don't think so. The one around 1kHz looks like a pipe resonance in the reflex port. There are techniques to reduce this if you think it's a problem. Over 10kHz it's probably something in the tweeter or waveguide.Would spot bracing fix the resonances ?
the horn is part of the tweeter and there's no resonance in the data sheet https://www.scan-speak.dk/datasheet/pdf/h2606-920000.pdfI don't think so.

The waveguide on the tweeter makes all the difference. I thought a waveguide would be difficult to implement, but not any more. Low cost too. I should throw away all my flat baffle tweeters. They are all obsolete.
Very nice review of a nice affordable DIY example. To me the ability to choose between all different kinds of drivers (Dome, AMT, Ribbon, compression, waveguide, ...) and cabinet types (sealed, bassrefelx, Transmission Line, TQWT, Horn, ...) is one of the biggest advantages of DIY. Here are some examples of other affordable DIYs using Wavecor waveguide dome tweeters:Baltic birch cabinet seems quite solid and well above what you get commercially. I was surprised to see a tweeter with waveguide. Typical DIY speakers lack that
This leaves me shocked. What excuse do large companies have for not designing and selling such a well-made speaker if a single user with limited means, with easily available materials and knowledge available to everyone can design such a well-measured speaker?
Look at the crossover - it's complicated, with a fair number of big and expensive parts. Here's a pic from the build thread.
This is the kind of thing that's "easy" for an advanced DIYer to do in small quantities, but adds up quickly in materials and labor costs for a commercial product. It's certainly doable, but probably not at the outlay one would expect for a 5" 2-way.
Regardless, really really nice mini-monitor design that's a great showcase for SOTA in passive designs using well-chosen drive units of reasonable cost.
Don't see any unreasonably expensive materials in this, but considering the n^2 for sale's price it might matter ... not for sound quality, but pricing.Look at the crossover - it's complicated, with a fair number of big and expensive parts. Here's a pic from the build thread.
