Would a small folded midrange horn work?

[freddi]

here's a stab based on that JBL 14" driver - at 0.88 with PA310 (already have that driver) - looks like a 55Hz speaker

Here's 0.88 scale based on that JBL 2217 example, but using a PA310-8. Looks like a 55Hz horn

I may depend from what type of musics do you lestening most and when they were recorded.

I my case I would think to reach at least 40Hz.

sorry - I hit the wrong graph -

anyhow here's the PA310 in the 0.88 scale manifold.

and for comparison - my builder's speaker - a 4.5 cubic foot reflex with Eminence Omega 18 whose specs are suited for 6th order work and they can have nice impulse response. (he doesn't do that stuff)

Are there plans with dims for the single driver manifold type ?

Elliot Thompson had a thoughtful post with regards to choice of horn vs reflex depending
upon genre and tempo.

There is the plan in the site to be adjusted, but if you send me the driver spec you are planning to use I could post a proposal for you.

But if the driver isn't small, the box will be bigger then 150L

I "should" have one or two Beyma 10G200. Does that qualify as "small" ?

Here's input impedance for smallhorn3 loaded with a Tymphany 10 "pro" speaker.
