This is interesting because I've seen speakers that are "built right" (construction), but don't sound great. I've seen some that measure well, but are a little light on build quality.
In some ways, the answer to this question is moot if "built right" is referring to "sounds good when you get it". Any speaker can fit that bill... with one catch... you just have to buy what you want and ship it to Texas. I mean it. Buy any speaker you want, and then make 1 phone call to GR... the answer will probably some version of "Sure... send 'em on in...". I watched Danny wrestle an Esotar tweeter into submission... a tweeter that is notorious for being difficult... (but sounds so sweet). He can fix any speaker you want, unless it's designed to fail from the beginning.
If the question is from an "enclosure standpoint"... my Wilson Duette are pretty impressive. They are built very well, but wanted bite my head off. But I wouldn't buy Wilson... well, there is a pair of Duette for sale, add $500 or so for Danny's upgrade network and you have a well built, world class soft dome 8" 2-way that sounds like a floor standing speaker for around $5k. Who would want that? I digress...
If the question is from the standpoint of really buying a speaker that you "take home and it sounds great... keep." For me, the question is whether that brand makes anything that "sounds bad", but they still sell it because it "makes money". If someone makes anything that could fall into the "junk" category... I am suspect of everything they do.
For brands I think I could throw a dart at and get something that sounds good:
- Anything Danny makes
- Speakers Danny has helped with... Usher, Tyler Acoustics, other brands he's mentioned in videos...
- Anything Andrew Jones makes, including Elac
- TAD
- Dynaudio
- ATC (change the resistor, raise tweeter level)
- Goldenear (hunch)
- Buchardt
- Acora (Bookshelf)
- YG Acoustics
Speakers I'd like to hear / own one day...
- "Unicorn" Line Array speakers...
- Duelund Coherent Audio Monitor (currently building) / 8" 2-way
- Danny's new LGK speaker
- Dynaudio Heritage Special (uses Dynaudio's best drivers)
- Dynaudio Contour Legacy (uses Dynaudio's best drivers)
- Dynaudio Confidence 60
- Dynaudio Confidence 50
- Dynaudio Contour 60
- Dynaudio Countour 20 Black Edition
- NX-Otica
- Custom Accuton Driver 3-way speaker
Getting good sounding speakers is the easiest part of this, I think. But that list up there... a lot of that stuff is very expensive. So, I just call Danny. He's made 3 pairs of my speakers sound "built right"...
I'm still eyeballing a pair of Dynaudio Heritage Specials though...
