Who makes the best "Coaxial" Tweeter/Midrange design?

@timlub - No doubt, Tim.  Alas, I have neither the skills nor the time to attempt such speaker surgery.  But even as is, they were a steal.

@bondmanp 
I changed the crossover a bit (changed slope, all polyprop caps, better coil), added zcomp, added felt to the tweeter ring and stiffened the cabinet.... 
You would fall over with the difference!

@timlub - I have a pair of the Insignia coax speakers on a shelf in my dining room.  Powered by an old JVC receiver, they sound amazing with music from my server via Plex on my computer, and that is just using the audio out from the sound card.  They would never be mistaken for high end, but for the price, they are killer.

The best I have heard was the Manger driver - mangeraudio.com.  Heard them years ago in a custom design.  I have heard some others, and, IMHO, these walked all over the KEFs I've heard.  I have heard the Piegas, and they are pretty good, too.  But who has heard ALL of them? 

Look at Piega.

Cheers,

I'd like to hear the Hsu CCB8. The word around is stellar imaging. Nice price bracket too.

Coherent speakers, out of Canada by Frank Fazzalari, are another coaxial.  They have received some great mentions but don't know much else about them.  The prices are attractive.

Are the drivers in the KEF Moon and Blade that much different from ones used in the Q series, R series and LS50s?  They all seem to be made with precision control.  Is it just the crossover components and cabinets that are upgraded?  

WLM speakers have a coaxial driver. I'm not sure whether they are still making speakers. 

Hi OP!

You may want to take this question, and search for existing answers over at:

You don't mention form factor. Eminence, Radian and others make 8" or larger semi-pro coaxials as well.

All Gradient speakers models use a coax unit made for them by Seas.

You know, its been 5 + years since I've seen a pair, but I've modified a couple of different pair of cheap speakers from Best Buy... It was an Insignia  NS-B2111.  They needed parts improvements, impedance correction and some diffraction control, but man, these things ended up singing quite well. I think I paid about $60 a pair for them. My brother still uses a set with a sub as his main speakers. 

BMS SEAS TAD no best just different options

KEF perfected on that one.

@roxy54 

I believe it's a BMS.

JTR. I'm not sure who makes the driver for them though. 

Every Thiel I heard was an ear drill, sorry. Maybe it was the McIntosh gear I heard them with? 

Best current production has be TAD or KEF. Thiel was also excellent. No longer in production but Tom Thiel, brother of Jim, is re-engineering the crossovers and these should be available by the end of the year at Coherent Source Service, the surviving service wing of Thiel Audio.

Timlub,

So in theory, Andrew Jones could be responsible for all of the coaxial designs at ELAC, KEF AND TAD...?  

Thoughts?

Quad! The 63 and it's descendants are a coax of a sort.

Andrew Jones,  was with Kef,  He did the Elac and I believe Pioneer owns TAD, but Andrew does it all there. 

Pretty much the same guy, but I'd go with T.A.D

Since your asking for modern,I would go with the designs by Kef and also the 12inch new production from Great Plains Audio.

Kenny.

I have had a few different KEF with uni Q and liked them a lot... the new KEF reference are great speakers

I do not know who makes them, but TAD uses a very nice sounding coaxial driver.

Thiel did !

If you like Classical Music . Tannoy .

Tannoy and KEF are great speakers, the design is decades old, and has been improved on, they are still being built today. I don't know if you could put Elac in the same category, most all their speakers are considered to be in the budget area, although they came out with a speaker north of $5000, perhaps that one would be able to play in the same arena.
