Default Quote Visaton M10 8 Ohm

Here is the scivvy so far,

In the USA, e-speakers.com is the sales agent. I told them I was volunteering for this entire group, so we speak with one voice.

They tell me this 4 inch is a new speaker, and they do not stock it yet. It is currently available at a $21.10 unit price-which is retail, and takes 20 days to get, since they have no stock in the USA. They are looking into what would be quantity pricing for us, and when they find out what that is, they will contact me and I promise to promptly post up here.

I did not try to go to Visaton Germany direct. The Visaton agents on different continents may take care of individual's needs on a world-wide basis, IF we ever deem this driver advisable.

Since this driver is JLH's baby : I suspect (a) we need to get him some, (b) (IF he has the time and interest to test these), and (c) he personally feels it might be cost effective

As you may recall from his previous postings, his Miscos he bought had a problem shutting off on the top end, and he had to resort to extra parts, compensation networks, to make it behave. I assume he would weigh the implementation of the new Visaton, hopefully with no "extra" crossover parts, versus the Miscos with added crossover parts. Just a guess.

A three-way Synergy with passive crossovers should likely NOT have the same midrange driver requirement, as the very nice design Paul Spencer optimized as a two-way Synergy with active digital crossovers.

As previously stated, if anyone has suggestions on how to interact with Visaton, in a better manner than what I have initiated, please PM me !!

Thanks and regards,

Jeff Medwin

Apparently Parts Express is now a Visaton dealer? Maybe we can get them from them.

Default Visaton M 10 4" midrange

I spoke with e-speakers last week, and the proprietor told me he would "get back to me" after he THINKS about how to handle our group.

Realize, this is JLH's baby, and there is not yet a large need for group purchases of these, until JLH determines if it is worth doing. Some here, I imagine, would LOVE to build an all-JLH designed Synergy. But JLH is unusually busy at work. The first eight may need to go to JLH to measure.

If you also immediately want eight, let me know and I will include you! Or, we can coordinate and you can do as you please. Just keep me informed please, for the sake of this group.

Thanks for posting about Parts Express. Excellent. I will contact them , early this week, and report back. It would be nice for end-users, the customers, to have multiple Visaton dealers in the USA, IF we use the drivers over other choices.

More to follow, anyone can PM me if you have questions, advice to offer, etc.

Default Confirmed, Parts Exprees is a new Distributor for Visaton

Parts Express announced this on the web, on 8-24-12. See this:

Visaton, now at Parts Express!!

It looks like they have 14 Visaton listed items so far. I will call them after Labor Day holiday in behalf of this group, and will report back.

Hi, any ideas if this one could get to 300Hz in a Unity horn? I recall considering this driver when all the good midrange choices for unity seemed to be available in US only but I then forgot about it as I thought the fs is to high.

Thanks!

The lowest frequency is set by the horn more so than the driver used. The local area of expansion dictates how the driver will get loaded and how low it can play.

Thanks JLH, also for the replies on the other thread, the Paraline.

I realise I don't have a full grasp of conical horn theory, I've always thought the lowest frequency performance is dictated solely by the 1/4 or 1/2 equivalent wavelength matching the mouth diameter. At least this was what I understood from Dr. Geddes papers on OS profile. Being the similarities between a purely conical horn and one that employs a conical section such as the oblate spheroid waveguides I didn't gave it too much though.

I'll read some papers on this so that I can clear it in my head and run some sims in hornresponse.

Thanks!

Without reading every page of the thread, may I ask - has anybody tried a horn with only one type of driver used, besides the faux-axial of P.Bateman? e.g. a full range at the apex and identical full ranges in the walls without a crossover besides the acoustics bandpass of the slots? Can you do away with a driver at the apex if you have FRs on each wall side?

And finally, how important is symmetry in the Synergy horn? What happens if you load only one side of the horn? e.g. if one face of the horn is the baffle of an upfiring woofer and the other 3 faces are bare apart from the apex?

I've been happily listening to omni-speakers (clones of the Demokrit that Oliver at 2pi-online has helped me with) but would like to make a horn so that I can hear the difference for myself.
