Great midrange drivers

[Goodman]

Anyone know of a great midrange driver equivalent to the ATC but at a reasonable price?

 

[freemansteve]

Are you just asking about a raw speaker unit to build into your own speaker design?

Satori MD60N-6 or Morel EM 1308 come to mind if you want something similar to what is used in ATC speakers.

If you are looking for something even cheaper, you could try the Dayton RS52AN-8.

Revel M105 Bookshelf Speaker Review

This is a review and detailed measurements of the Revel M105 Bookshelf/stand-mount speaker. A member was interested in it so I decided to buy it through our company. The retail cost is US $750 each for a total of $1,500 for a pair. NOTE: my company, Madrona Digital is a dealer for Harman and...

It is tested and measured here, FR on and off axes, distortion levels at different power levels:

SB Acoustics SB15NBAC30-4 | HiFiCompass

The THD measurements at distance of 20 mm and voltage levels from 4 to 5.6 Volt were carried out with High Pass Filter "on" (4th order Butterworth type, 20 Hz cutoff, HPF4-20). The THD measurements at distance of 315 mm and voltage levels from 2 to 4 Volt were carried out with High Pass Filter...

Copied here, see also page 4 in the thread where the element is used in another DIY as a midrange driver:

I'm trying to have the waveguides printed by materialize.com - however, the STL file does not get imported in the right scale and I need to manually have it scaled up. Does anyone have the right measurements for the waveguide?

The slightly larger variant with ceramic coated surface:

This is used by many. Incredibly good sound, performance for that price. Just think of relatively low sensitivity. When to match it with other elements:

Taking in account the high technical performance and very low cost, TC9FD18-08, in my opinion, is just incredible speaker!

Peerless TC9FD18-08 | HiFiCompass

The THD measurements at voltage level 2.83 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 80 Hz cutoff, HPF2-80) The THD measurements at voltage level 4 - 11.2 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 150 Hz cutoff, HPF2-150)...

Another tip (which I now see that alex -z has already tipped about):

Dayton Audio RS52AN-8 | HiFiCompass

The THD measurements at distance of 315 mm were carried out with High Pass Filter "on" (2nd order Buttreworth type, 300 Hz cutoff, HPF2-300)

The realism of the mids with the RS52AN is astounding. It's not simply the clarity and transparency. It's fast. The attack of the voices and instruments must be heard to believe.

Thanks for the tip, what are the other drivers?

Yamaha JA-0801 8.8 cm (3.5") Beryllium midrange dome! You would please Search in this ASR Forum by "JA-0801", "Yamaha dome", "Yamaha Beryllium", "NS-1000", "NS-2000".

This thread entitled "Midrange dome drivers banned ?" would also give you much info on Yamaha JA-0801 Beryllium midrange dome and other great(?) midrange drivers.

TAD's CST Driver consists of vapor deposition Beryllium midrange corn (16 cm) plus 3.5 cm tweeter Beryllium dome. You would please refer to my post here.

If you don't have a design goal, kinda hard.

 

[Wolf]

The RS52AN is no longer viable as they have changed and now no longer have flat in band response.
That said, I've never been a fan of it.

Dennis Murphy has used one of the Tectonic drivers with success.

equivalent to the ATC but at a reasonable price

Considering ATC's price, Bliesma M74 is reasonable, right?

 

[JPA]

Volt makes a copy of the ATC SM75-150. I've never seen a review of it, so don't know if it's the same quality.

Bushmeister got solid results from the Volt in his stacked spheres. But he also got amazing results horn-loading an SB65, so it's clearly not just the driver.

The SB Textreme. I use hte MW13TX and love it. Works great with an Augerpro waveguide and SB26ADC or Seas DXT Smooth response and easy to filter.

As if it wasn't famous already, yes, it is. To drive it to reasonable perfection it is best used from 500Hz to 1500Hz using two side by side, esp. not one over the other. The radiation pattern remains wide, don't worry. Add a waveguided tweeter, e/g Vifa 270.
