I wouldn't call them that.

Seas 2.5 Way Graphite Kit - Delling
Hi Everyone,
It was getting to be that time of year when I encourage audiophiles to build at least one speaker pair in their lifetime as a matter of personal growth and education. The more builders we have in this hobby the less we rely on PR and reviewers alone to influence us, so this is something I feel has broad value to our hobby.
Anyway, I was checking out Madisound, and discovered that Seas has released a 2.5 way kit which looks very promising. 2.5 way speakers are, IMHO, some of the best designs for the average living room. Highly efficient, deep bass, small footprint so easy to live with overall.

At around $1,750 for the parts, including a crossover, this is not the cheapest possible kit, but certainly far cheaper than a commercial speaker would have to be.
Unfortunately I have not heard this pair myself, and I worry it may have a little extra presence, but that’s the beauty of DIY, you can tailor your sound directly in the crossover.
Best,
Erik

Hey Prof - Perhaps some of the most well understood aspects of mathematical modeling of speakers has to do with matching a cabinet volume, and port (if any) to a specific driver to achieve a particular low frequency response. A free tool which does this which I have used is WinISD: http://www.linearteam.org/ but you can also use commercial tools like BassBox Pro and even online calculators. This is all thanks to the standard measurements given the Thiele/Small parameters of a driver: https://en.wikipedia.org/wiki/Thiele/Small_parameters The driver's diameter, resonant frequency, equivalent volume of air (Vas) and Qts are among the most important. Fortunately, vendors like Madisound or Parts Express will often recommend specific cabinets for you, either with exact dimensions, or give you internal volume and port sizes, with the projected -3 dB point. In practice, Seas, FaitalPRO and Scanspeak make a number of 6.5" mid-woofers with remarkable bass output for the size, if you put them in the right cabinets. I find the trick to this is good room acoustics. Best, E |
