Design advice for floorstander

gilera,

If you don't mind me asking, what sort of music do you usually listen to?

Single driver, wide-band (aka full-range) speakers usually do very nicely with genres like acoustic, jazz, and vocals, and even pleasurable with some rock like Dire Straits at moderate volumes; however if the music is more complex and heavy, and you like it LOUD, then they do not fare as well (AC/DC - not so much 😉). Same goes with most low watt amplifiers. 🙂

Personally I do like heavy music but my wife does not like it so much so therefore I don't like it so much anymore🙄

It is mostly for low volume listening of a wide variety of music from 60's to 90's. Rock, accoustic, reggae, alternative, grunge, punk. Kids will be sleeping close by so I want something that will give me good presence at lower volumes from about 3m away. I figure that a sensitive FR might be able to best acheive this. Also will cope with use for TV (not worried about action movies, or surround sound).
 
gilera,

From my experience, a 2 way or a FAST speaker will do better for genres like alternative, grunge, and punk. Lot of these recordings are on the "thin" side, and tend to sound bright and thin on a single wide-band driver speaker. Remember, you are getting limited cone area with a 4"-5.25" wide-band driver. A dedicated mid-woofer+tweeter or mid-woofer+wideband is more versatile (albeit different sounding and can have different amplification needs).

Stuff like Diana Krall can sound very engaging with a small low powered amp and a single wide-band driver speaker. 🙂 For TV and vocal ineligibility, they do very nicely as well.

Well, they say all speakers are compromises, and you choose your own poison!

Any suggestions for a speaker combo or validated design which would suit low power class A?

All I have built so far is a pair of Overnight Sensations.

Sorry, but I keep coming to the TABAQ with Faitals. But no love. 😉

They offer enough grunt down below to satisfy most of the time, (for movie watching, you can use the sub output of your receiver and add a sub or two in the room), have exceptional treble reach, and at 91dB sensitivity, will offer you much more than the other options mentioned, especially after adding a BSC filter, which will really cripple other drivers.

Plus, the shape has one the the best WAF acceptance.

If sensitivity is important, I agree it’s tough to beat Faital Pro 3FE25 as Perceval points out. But you can double that sensitivity by using dual parallel 3FE25-16 in mini Karlsonator. That speaker combo has been verified to work really well with low power Class A amp like the ACA. Its sensitivity is theoretically 91dB +6dB for the parallel driver connection.

Mini Karlsonator (0.53X) with Dual TC9FD's

However, you would need a small stand - which in my view is worth it. Here is what they look like on a small stand - we are using them as the mains for a TV in the dance studio. These were a set made following the plans by jhofland and finished in 15 coats of hand rubbed lacquer over espresso brown stained BB plywood with baffles covered with Duratex in black.

I think the 10p in the Pencil is your best option and worth every dollar.

But, a slimmer, smaller and less expensive option is a version of the Castle referenced above, using one driver pair. I recommend the CHR-70 driver. This speaker is readily built using just one 2’ x 4’ sheet of plywood per channel.

MARTELLO-2, a mini-tower from a single 2' x 4'. - I used the now obsolete EL-70, you can use the CHR-70. These are small enough to flank a TV and be a real spouse pleaser. Bass is very good.

Both of these options have been used with a low power tube amp with great results!
