Thank you for the explanation Dave. Makes sense. Very much appreciate you guys who take the time to explain to the inexperienced what must be somewhat mundane to you. You and others like Scott make this hobby a pleasure.For larger drivers —
Elekit 8900 and a diy 45 type.What amp?
Apologies for the newbie question but I'm looking to build my first set of speakers and the Frugel-Horns with these ma200s looks to be a good place to start. I currently have some focal chora 816(I like them but bottom end is 50hz and they need more bass) and often listen at low levels. Will MA200 Frugel-Horns be a decent listen at low levels? By low levels I mean I don't often go past 9 o'clock on the volume knob on a roksan k3 integrated.

Apologies, Joan!Joan…

Looking at the VAS for the MA200 and my very basic understanding of speakers(be kind, I'm trying to learn) it looks like the Joan is a little undersized at around 46 liters on the internal measures I guessed at from the drawings I saw? If all the measurements were increased by 10% it would equate to around 64 liters which appears a better match. Would the increased height of 3 inches cause issues with the listening angle or should I just keep the speaker at the same height as in the Joan?
MA200i right on the edge of fitting Joan. It will likely need more than the usual amont of damping.

I'm listening to deep-enough bass (organ, piano, bowed bass viole, plucked doublebass, bass drum etc.) in 17L TLonken, room-reinforced. The lowest notes/accompaniment are heard cleanly, not as the "lead" of the ensemble and not overly loud in an apartment with neighbors.
Mark Audio MA-200 in 17L 1.5m TLonken with "strait" port following Elac and AIRS (a Chinese brand) whereby a circular-curved strait constricts then expands the slot port. Toed-in near the corners of a 3.5m-wide room, at the rather small sweet-spot, clean even response ~40hz to 12khz with both ends modestly rolled-off but still playing the right notes nicely (i.e. acoustic instruments covered full-range). Exceptional for a whizzer-less 8" run straight-through without filter/EQ. AlMg cone not as dynamic/articulate as paper cone especially playing low-volume at night (then loudness...

could you post some pictures or plans, maybe? transmissionline-onken sounds interesting17L TLonken
I have been meaning to ask about increasing the size just a bit, like in only the width, say be 1/2", etc to gain a bit more volume?

I'm not an expert like @GM or @Scottmoose but what I've learned from building speakers is that a small change here and a little change there will not make much of a difference.I have been meaning to ask about increasing the size just a bit, like in only the width, say be 1/2", etc to gain a bit more volume?
You are probably correct in this situation but never hurts to ask eh? 🙂
Though just 1/2 in in width should add up to a fair amount of volume in the Joan size Frugel-Horn and easy to adjust the plans to it.
I will do whatever is recommended of course!

Just under Butterworth assuming light damping, a voltage source amplifier & only modest loop resistance from speaker leads. Might be slightly underdamped in practice through boundary gain, but you could always bleed some pressure off if necessary or increase the internal damping a bit.
