Quarantine Project--A Full Range Speaker Kit


Being in full lock down mode, I looked for a small project to give me something to do on weekend evenings usually spent socializing.  I decided to purchase the Mark Audio Tozzi One kit from Madisound.  ~$160 with drivers and cabinets.  It's a ~3" full range driver with no crossover.  The cabinet is handsome in a very modern way.

This is an extremely simple kit, and something you could do with older children that have an interest in audio.  

As for the sound...well, this was my first foray with modern full range drivers.  First the bad points:  (1) these are small drivers, so there's very little output below say 100hz.  (2) I believe the cones are aluminum, and I don't think I'm fooling myself into thinking there is a "metal cone" coloration to the mids -> lower treble.  I know it's there, but it's not too distracting.

That all being said, and keeping in mind these cost $160/pair, I think they are rather remarkable.  The clarity / purity is really tremendous.  And they image really nicely.  Treble extension is fantastic; there's no sense of missing a dedicated tweeter whatsoever.  I am now motivated into experimenting with the higher end (and larger) Markaudio drivers.  They are really onto something.

For fun, I hooked them up to my home theater system so that I could hear them with a subwoofer.  It seemed to highlight the fact that they throw up a rather small soundstage, but other than that they were really enjoyable!

Definitely check out the many Troels Gravesen designs.  They're really very interesting.
@cedargrover, quite! I got a pair of M/W-frame flat packs free from a guy on AudioCircle (I believe it was), but also bought a pair of H-frames from the guy in Canada who is making them for GR Research customers. They're what Ron has. The OB/Dipole Servo Sub is the closest thing I’ve heard to planar bass (I have a pair of Magneplanar Tympani T-IVa), which I love. But those Tympani panels take up SO much space! I presently don’t have a room big enough for them.
@millercarbon, astute observation above.

Learned this many years ago. Seattle audiophile club had a speaker building contest. Only rule: $100 parts limit. Not including the cabinet! Whole bunch of entries. Most truly awful. The top 2 or 3 were pretty good. Out of about 30. So DIY, real deal genuine DIY, is damn hard. What hit me was even the very best one was still not quite as good as some manufactured speakers you could buy for the same amount of money. And that was with the DIY given a pass on the most expensive part, the cabinet!

So clearly the professionals know a whole lot, probably more than we even can guess at. In other words a whole lot of design went into that kit you put together.

With any luck you totally got your money’s worth out of the experience. You got to see first hand what goes inside, and all the details of how a speaker is put together, and just how much work it is even when someone has laid it all out there for you.

We take it for granted, but its not easy what these guys do. Not easy at all.
