what 2' inverted soft dome, cheap

[robywan]

high im looking around for some cheap 2-3 inch inverted soft dome mids for a open baffle system and im wondering what you guys could suggest that is budget concious ($100-250 for a pair)
and has at least a 80 wrms power handleing and a freqency response from approx 800- 6000 hz

Hi,

2" inverted soft dome ? I'm not aware of such a beast .....

I'm also no expert on Australian driver availability.

THe Hi-Vi DMB-A seems good value, see tests at www.Zaphaudio.com .

I've not seen a 2" inverted dome either FWIW.

 

[BHTX]

Me either, I don't think, for what little that's worth.

Thiel/Accuton makes a 2" inverted dome...ofcourse its a hard dome and not soft there should be a new one with higher sensitivity and more wideband, but seen yet...theres also a 3", but not very wideband

 

[Dr_EM]

Is this not a 2" inverted dome?:

Hard cone either way...

Morel MDM-55 is supposed to be quite good

 

[KCHANG]

or the Aura Sound NSW2-326-8A

which is used in Dr. Linkwitz's Pluto speakers. Not a "soft dome," but quite usable, and cheap too.

i was confused

sorry guys this is like the first time talking about speakers to other lovers of audio i ment that they are convex or dome out, concave is what i have for all other drivers (woofer subs and orginal mid)

thanks guys

I was looking at some of the older Morel MDM 55 dome mids but they are expensive for this project

I looked on this site (zaphaudio), are these american prices, if so these are still very low, and i can see my eye on some of those drivers

thanks sreten, from tobe

is it true that a smaller diameter dome mid will do equal to or more frequency range as a big surface area cone such as the ones I'm currently using.

just verifiing that, ithink the morels will be a hit, a bit on money spending is in order guys

 

[sreten]

Hi,

What you gain at the top with a small dome you lose at the bottom.

A big issue with dome midranges is excursion in its lower range.
You cannot just look at the frequency response, the limit is usually
the dome size and its linear excursion.

discussed for a 2" in here : http://www.zaphaudio.com/ZDT3.5.html
But note the c/o is first order electrical, 2nd order L/R acoustic.

There is a offer on a Morel dome and an alternative Hi-Vi.

Most 2inch domes suffer from needing a crossover in the part of the audio spectrum in which our ears are most sensitive.

Jaycar 2"dome were avaliable some may be left in stores otherwise email me for a price on 3 unmounted, I decided on a different configuration.

Hi guys, in the process i discovered a cheap revelty avalable 5 inch inverted paper cone drivers from jaycar (australian) that i had the chance to listern to at work, i kind of stumbled apon them. From first impressions of the open construction they sound much more open and less contained than the closed back drivers i currenlty have.

I give em a go as they are easy to get and are cheap.

Thanks every one for suggesting, maybe i might use the morals as part of a new pair in the future as these speakers are like my first project to be used semi permantly.

I remember AndyG saying these Are rebadged Hi-Vi drivers, if so probably worth the experiment, the 8inch are pretty good at bass, no personal experience with that particular driver

that's cool, i will try them and get back, my boss had to order more in because the ones listened to were sold the following day.....damn

they will however be loud compare to the tweeter and those to compared to the woofers, i will have to design some attenuation circuits in the new 3 way crossover that were needed any way, hit to birds with one stone.

thanks for the reply

Rob,

I got some of these from eBay. The guy has sold at least 2 other batches (of 4) since and he may still have some more.

OK, they're not inverted, and I'm not sure of their bass range if you run them O/B. But I think they might be something like what you're looking for.

Martin Colloms mentions these specific ones (and has a photo) in his High Performance Loudspeakers book.

 

[robywan]

i had a look but no more, im just going with the ones from my shop and see how they go, should be good thanks anyway Rob, its the though that counts, i might use some higher end stuff in my next project as it is hard to get my hands on stuff and the time, im still at school doing god damn HSC

 

[robywan]

hhaha didn;t think it would be the way down the page of the listing, they look good and cheap i will keep in these on my mind just incase a new project comes along.
