Default Mark Audio Alpair floorstander, pensil - horn or?

I am interested in good plans on making a nice looking, compact floorstander for medium levels and mostly acoustic/americana/jazz and bluegrass music. Absolutely no techno/metal and the kind.

The Mark Audio Alpair range looks very nice but I have som questions:

- Is the Pensil and the Frugal Horn the only known and recommended floorstanders?
- How big a floorstander of this type would be required to fill a room of 6 x 4 meters. (24 sq mtrs) at low levels - sub 95 dB.
- I want a design that is fairly slim and pretty.

They will be playing on their own - no bass-assistance.

What plan would you recommend?

Bob Brines has an ML-TL and there are the Woden Design horns. If you are mentioning the FH3 then the Alpair 7.3? Bob doesn't have an ML-TL for these, the Woden Design Horn is Mashowe (it is not compact thou).

I haven't bought drivers - I want info on good plans that are fairly easy to put together for a normal person.

The FH3s seem to need a lot of space behind them?

I have looked at the "pensils" on the Mark Audio-website, but they look a bit... plain? On the other hand, they seem easy to build.

FH3 was designed to use a corner or a wall behind to extend the mouth size.

One of the design goals for the Pensil was simple. Note that the optional holey brace can be as much work as the entire rest of the box.

(Note: same designer for both of these -- Dr Scottmoose)

edit: Dave beat me to it.

FH3 shouldn't need all that much space behind it (ditto for Maeshowe) since they use boundary loading. A bit, yes, but we're not talking yards by any means.

You can glitz up the cosmetics of the pensils if you feel they look boring. Or I could do you a one-off cabinet, depending on what it is you want. The criteria you mention above isn't too much of an issue, but aesthetics are of course a matter of individual taste, so some further detail wouldn't go amiss.

Thank you. Don't get me wrong - the pensils look very nice.

The FH3 is a bit above my current woodworking-level right now, but they look very cool - I am thinking gloss white and gold driver e.g. I see there is a shop selling from Netherland, but they would cost a bit when shipping and taxes are added.

Pensil 6, 7.3 and 10.2 look like good sizes, but are there any measurements to be seen? How much power would these require?

The 6 would look very cool in the room, but I am thinking they have trouble powering 24 sq mtrs with decent bass, or?

The second design here is interesting but the frequency plot on the right looks miserable? Alpair 6M | Markaudio

Yup, a single pair of A6 in any type of enclosure would have trouble filling a room that size

Of the Alpair drivers, I'd be included to suggest either the 7.3 pr 10P in Pensil / MLTL style enclosure - for simplicity of build- and as Dr Moose, who draws a lot more designs than he's able to build has noted , you can tart up the aesthetics as much as you like. . The 7.3 could still benefit from high-passing and woofers, the 10P I think would suffice without. Certainly does in the FHXL -FH3's big brother.

These drivers really make me wanna build some more speakers. Fullrange-drivers are just fantastic for many types of music - the coherence is so addictive.

So, Pensil 7.3 or 10.2

oooooor

Frugal Horn with 7.3 driver are on the short list. Will investigate further.
