Single driver speakers - opinions

T_Bone, the bass compares favorably with that of my Meadowlarks. The Madisons need no bass reinforcement as mine are 6’-7’ from the walls.

Soundwise, the Meadowlarks now put me to sleep. They sound so terribly slow compared to the Madisons that I had to relegate them to HT duty. (And I really did like them a whole lot before)

As I mention, I cannot hear any dips, but I suspect we are not sensitive to dips in sounds as we are to peaks. My room is heavily treated so this could possibly give me a flatter curve than the one posted. It’s difficult to say - I go by ear alone and don’t let measurements drive what I like or not.

Tybones have great image, speed and soundstage....no question about it.

Bass is dynamic and tunefull but if the last two octaves are important to you, I would consider the Sachiko double horn design and 8" Fostex instead.

Your spiral idea is quite difficult to execute.
I am working on the similar design as we speak and I can tell you that it is far from easy. In fact, my design includes
double spiral horn with omnidirectional qualities.

It should be fun playing around with those.

Thanks Gents (Mariusz & Pauly),
The last two octaves are important to me because I think they're important to the music.

Mariusz, couldn't the spiral simply be a matter of switching the "hole" to the side (covering the front), and switching the stacked ladder (which is seen in the back corners of the top and the bottom) so that it guided the wave out that side rather than the front?

That is not what I had in mind.

Your above proposal is not so simple , necessary or present any benefit over the original design.

One of Sachiko's design benefits is that the speakers can be placed relatively close to the front wall.

You can always try to improve the build quality, tweak the box and the driver.

I will include the link tomorrow what I had in mind by double horn spiral design and omnidirectional wave guide by the use of cones at the top and bottom mouth exits.

Another interesting design would be a single spiral horn with driver firing upwards towards cone-dispersion piece for omnidirectional qualities. A use of the super-tweeter might be necessary or helpful in getting the right amount of resolution and air.

It is going to be a bussy winter. :)

Hi T

Sorry for the delay in my response, as I haven't been visiting the board lately, and I would like to thank Pauly and Mariusz for their input. The new CarderSound models(Madison on down), are completely different than the DIY plans on Frugal-Horn, so a direct comparison would not help you. They are not even based on the Frugal-Horn designs except for their similar outward appearance.

For what it's worth, Pauly and Mariusz are exactly on the mark. To answer your question more directly, have no fear. In practice, most of the nulls shown in the graphs for the FH models will not exist -they're mainly caused by limitations in the software.

Hope this helps.

Best,
