What that is depends on your partner.

… a set of four Decca Kelly Ribbons (DK130)...

A box of gold, and not just the colour. The London was a significant improvement, you could use the driver ribbons in the DK130 to drive a diyed London Horn. It was usually taken down to 1.5kHz, but i heard a set of Decca prototypes that crossed at 1kHz (and got to tweak them to improve them), iwas quite taken at the time.

Shape and finish is likely more important than sonics, a smaller box will likely be vented, you just have to chose a design concept that you like and get creative with the cosmetics.

These aren= an example of a small reflex not in a typical monkey coffin.

A12pw, these about 35 liters, i can d an alignment that fits them in a box about half the size.

Most of the examples shown so far are based on an not-rectangular prism, the aboveuse a trapezoid (with 4 additional chamfers making it 8 sided).

Geoff’s JR examples are the classic example.

but she likes the sound of the Quad ESL 57s the most…

Whatever you build will likely have better bottom, what you are looking for something that has amidrange similar to the ESL. First that pops to mind is MA Pluvia 7HD, but you’d want to listen to them before adding the Decca. It could be supefolous and you need to find another use for them (probably worth many hundreds of €).

My buddy with triple QUADs used/uses a DL130 to help the top. A set of µFonken produced better mids, connected to his system. But that was before he restored them. Still shows it is possible.

Thread 'My submission to the "Better Homes & Donga's" speaker competition'

Firstly, for non-Australians: In this country a Donga is a temporary accommodation building typically used at fly in fly out remote work sites. The rooms are like VERY small hotel rooms, with an en-suite bathroom, a beer fridge, and not much else.

These speakers were inspired by suzyj's noisePlank here: noisePlank - a simple folded TL with TG9FD10

I sometimes visit the same remote site as Suzy, I'm trevelling there now, and have the same need for good sound in my donga. I didn't want to just copy the noisePlanks, and owning and very much liking a pair of Linkwitz LXminis I...

Ha ha, you guys make me laugh. I also have a pair of stats, about the same height as the 3 stacked quads, but a bit narrower. They were confined to the storage room when I was away for a few days. Banned from the living space. Pity, they sound divine, best mids and treble I have ever heard.

It's the dipole diffusion of bass that hurts you, as longer wavelenghts will bounce around the room many times and what you hear is a mix of direct & environment sound, with the backwave ( 100% anti phase) making a mess.
Compromises, yes. Two towers filled with 4 X8" stacked, high excursion. Better, two 16 Ω paralleled ( I don't fell comfortable with the serial-parallel connection) units.

Thread 'Flat Wall Mount Stereo MLTL using TC9Fs (2)'

This thread is being started as an OT discussion from the Tabaq thread. The design is a compact flat wall mountable stereo speaker that has great midrange clarity and pretty decent bass extension due to the mass loaded transmission line (MLTL) approach that was added to the original design based on this thread. The original open-ended TL design looked like this:

I modified the dimensions of that design to fit two speakers on a single panel of 20in x 30in foam core board. The revised design plan is as...

^ No turntable.

My wife just makes comments about the wires... so I try to hide them behind the racks and route them along the shelves and so on.

The Maggies are white and pushed against the wall when not used, so they are not obvious. The Little ANs are beautiful wood and she hasn't complained about the lead filled 24" Target stands for them...

I did put a plastic plant hiding some HDMI wires in the HT.

The big speakers in the HT are beautiful rosewood, the TV table is a sofa table with beautiful walnut and then I got a nice rack for the components.

In fact, I now have FIVE racks from the same manufacturer and shelf finishes. Got the last two used off Craigslist. So, I got spares... ;-)

Dave, et al... those pictures... those have to be your home office, huh?

Maybe I'm too anal retentive, but all that stuff on the floor and all of those wires would mess with my mind. Even in my home office I try to keep it neat...

Here's an example of how to "hide" the speakers... notice the "mass loading" and how it makes the speaker look more like a stand for objects d'art...

And when you feel like Don Ho... yes, the wire was an issue... so I had to dress it...

I know your problem as I share it. What's more, I love low power valve amps which tend to work best with large speakers.
My compromise works well and has very good WAF, being just over 8 inches wide and 1 metre tall. Arguably, a tower speaker can be more elegant than a stand mount speaker of the same width as both tend to be of similar height.
Have a look.

Post in thread 'SET Friendly MTM, Seas ER18RNX and 27TDFC'

If anyone is interested in the amp I use, I have posted about it in Amplifiers, Tubes/Valves with the title:

SET for Real Speakers - Principles

Makes sense to me to consider this matter from both directions, designing speakers for the amp, and designing am amp for the speakers.
  • Thank You

If you are interested, I can give full build details. The value is very high as the drivers are high quality but medium price, well behaved needing little correction (just a small cap to fix a very slight peak in the tweeter); can't go wrong.

All,

Looking after a speaker system of decent quality for a modest apartment (about 5 x 7 meters), but accepted by the partner. So, a not-too-ugly form and modest dimensions. My own requirements are in the direction of little distortion and good imaging, moderate listening levels.

I'd like to build it myself, having enough experience as a furniture maker, I probably can manage to make cabinets, but it would be my first speaker build in about 50 years. The last one was a Wharfedale kit with the drivers from the Dovedale 3 model, so about the early 1970s. I read that a first attempt would better be to take a proven design -- I have come across a few that are tempting, but I'm still unsure about what to select. Unfortunatey, one cannot go out for listening tests in the DIY area.

I think about Troels Gravesen's Discovery-12W with a (too) expensive tweeter or xrk971's FAST/WAW monitor with the 10F/8424 and the RS225-8 drivers. I have also been given (really!) a set of four Decca Kelly Ribbons (DK130) which I could combine with a Mark Audio Alpair 12W (as advised here), but then the cabinets' recommended size quickly becomes an issue. Ideally, I should have not more that 50-60 cm centimeters of height. As it is a first attempt , I am thinking about a budget of +/- 400/500 euro for the drivers, so there's not too much lost.

Other ideas are welcome! My music preferences are more towards jazz combos, vocal music and a lot of classical/preclassical music. In my man attic, I'm using Quad ESL57 speakers, just to make that clear.

As there is a Bang& Olufsen showroom just around the corner, my spouse has remarked the Beolab-8 speaker and she likes its appearance a lot, though not the price tag. So I could attempt something similar to this (design can be better, I could 3D print look-alike aluminium or bronze parts):

But adding this kind of cosmetics may be detrimental to the sound. A speaker grille or front isn't always for the best, so it seems. OTOH, there are grandchildren (and cats and dogs) which may be tempted by those cones that bounce when you press them, so some covering could be beneficial. What are the ideas about wooden strips as a grille?

Your comments are welcome !

Cheers,

Jacques
