I have only built or heard the Cubos, and they sound pretty good. They say the Tham speakers are very good, but they require very specific drivers that are much more expensive. The beauty of the Cubo design comes from its very forgiving nature when it comes to speaker selection and the ability to use more budget drivers.

They do ? This is a most likely a common misconception stemming from the choise of example driver, the rather but rightfully expensive 15TBX100, this leads people to think, without investigating it, that this is or simillar priced or T/S spec'ed highpower high quality drivers are the only ones for the job in the design, adding to that it's a TH, and we all know about them right :)

This is not true, infact the THAM series are rather forgiving to driver spec variations, mainly due to the generous volume coneside wich means less stress on the driver due to compression effects, high compression may yield a "better looking" response graph in a sim but can be desaterous in reality and it does, no doubt, decrease the designs driver tolerance.

All the respect and praise to David McBean and his creation Hornresp without which alot of us would be lost and unknown in this field, myself very much included, I simply can't describe what a positive effect this man has had in the global loudspeaker DIY comunity, but do not forget that a sim is just a sim, it's not reality, it's a theoretical approximation that sometimes hits the spot and some times don't, as simple as that, what you see is not allways what you hear, but most of the times it is.

Returning to what "they" say about the THAM's being picky on driver specs, well, in all honesty I probably would have taken "their" word for it aswell, especially if they are prophets of the trade, and some, most in fact, of my designs was initially met with sceptisism, pointing at designflaws claiming this and that in theory not having built anything or litned to any of it, producing "better looking" sim's and scarying people away from someting they do not fully understand since it is not in a book somewhere, those kind of people can dangerous to development and creativity, sorry about the rant, no offence intended, but I'we seen these types of claims for i while now and wanted to give you another angle on it.

The Cubos are very nice and well thought out designs that are rightfully claiming a lot of ground in the global DIY community, and they are surley even more forgiving on driver specs compared to the THAM's given their even lower compression, and in this case it might be the better choise.

Stay scpetical, it's healty, but also keep an open mind, and never forget to question what "they" say, no one is above being questioned, seeing as should they be they would still welcome it.

That's good to hear. A long while ago, when I built my first set of Cubo's I was trying to decide on it or the TH. At the time I couldn't find any driver recommendations other than the what the plan called for which was twice the cost of what I used in my Cubo's. I was just repeating, what I now see as, outdated information that I read back then.

Because a traditional tapped horn like the THAM doesn't have a compression chamber to speak of, I would be looking for low Vas, anything between 100 - 150 L (lower OK) and preferably low Qts drivers, personally wouldn't go much higher as 0.3

Best regards
