Frugel-Horn Mk3

[sarathssca]

For making FH3 enclosure removable, for adjusting damping or changing drivers in future, can we have the whole front baffle as removable ? (have a thin wood strip all along the internal lining of the front part of the enclosure with some T-nuts at the back of them and then screw the front baffle over it )
Or have half of the front baffle fixed on the enclosure and top half removable as above with screws and T-nuts on thin wood strip on interior of the front part of the enclosure.
Or its enough to got with a regular rectangular super baffle without the side wings for adjusting the damping.

Would drivers from CubeAudio also work in the FH3?

I don't see anything smaller than 8" on their website, so no, they won't physically fit in an FH3.

After many TQWTts build over the years (which I love despite the flaws) I am building a Frugel-Horn Mk3 for the first time. So what can I expect over a TQWT re. Sound presentation?

 

[planet10]

Depends in how well designed the Voigt is (ideally an ML-Voigt).

So if the voigt is designed well I wouldn't expect any difference in presentation?

They will load the room differently. But potentially similar bass output.

Nice. Thanks Dave.

I'm curious what flaws are you referring to? The FH may have similar issues.

any thoughts on this one? I find it interesting with the downward/floor firing exit allows you to essentially tune the size of the exit to your liking for any given driver used... Might it have better bass esp with room corner placement?

 

[planet10]

The shape of a Voigt pushes the harmonics down in freqiency making them harder to kill. Mass-Loading really helps, from there driver position and the damping.

A poor one will have a ton of ripple, a well done one nice.

To explore the challenges of getting damping right with no mass-loading, see the challenges that BIB builders have had.

Any mass loading would have to come from the proximity to the floor, but it would need to be closer than shown in the drawing. I expect it to be pooristh.

so in general then forward exit like this is better?

poorest compared to?

Rear vent can help but the one you show has a mass-loaded vent.

Compared to something without ripple. ML can also push effective fudemental resonance down.

Maybe flaws was the wrong word. I was thinking about the ripple they are renowned for. Even though it has been addressed with good design as I understand it, and just wondered if the FH had a similar trait.

 

[planet10]

FH3 is a much more sophisticated design, the bottom terminus one is just a straight/simple Voigt.

That's an understatement!
