Been way too busy for audio, but just wanted to let you guys know I found an interesting 4" sealed back mid-range. If somebody has the time, look into it and see what it will take to get some. Please share what you find out so everyone can benefit from it. Back to the salt mine now...

Shipping from down under to the states will be too costly. Not to mention customs will also rape you on duty taxes.

Default May I volunteer ??

Hello Antripodean and JLH :

May I volunteer ?? I am less busy than JLH.

I suggest we all keep an open mind and investigate BOTH the Celestion and Visiton four inch sealed back drivers, and use the best suited ones !! One brand may be far better than the other, depending if its a two way Synergy horn, or, a three way Synergy horn design. Right !!??

It seems like Viston sells world-wide through dealers on different continents, and usually handles "technical questions" direct in Germany.

Since there presently seems to be a world-wide interest in a DIY Synergy Horn project, and it will likely be on-going, having a world -wide sales network and driver availability may be both cost effective and positive. Each end-user will likely have to buy eight drivers for a pair of stereo horns.

I think its good to speak with " one voice for all " to Visiton, and I volunteer. I am sending an email, and will telephone them on Monday.

Allow me to speak to the USA sales reps initially. We will figure out cost structures and the most suitable way, to make available, first to JLH and potentially to the ENTIRE Synergy DIY group (on an on-going basis), these Visiton four inch drivers.

Lets leave it to JLH and Antripodean to give us the DIY design and driver selections that work the best. They are well-qualified to do this engineering.

I am happy to help, and will openly post results in a timely basis, for all DIYer's information and benefit. If there are any additional topics I should determine from Visiton, please post me up here.

Thanks to all.

Its not that difficult. Just plug the driver parameters into hornresp. Do a conical horn with offset driver. Adjust the corresponding parameters until satisfied with result. Driver has to be relatively small with strong motor, basically every 4-6 inch PA midrange should be workable, as you will have to eq it anyway a little bit. With two midrange drivers, you can go up to about 8 inch. Doesnt have to be closed back either, if the horn is two way.

Thanks,

I was running the Misco in my car for a couple days, and the surround came off. It's been in the 90s lately, and I'm guessing that the heat made the surround seperate from the cone.

The Misco *sounds* a lot louder than the Pyle, but my hunch is that it's mostly because the Misco cone is untreated, so it's high frequencies are louder.

Long story short - the Pyle works pretty darn good. If I had to do it over again I'd probably stick with it instead of buying both the Misco and the Pyle. And if I was the owner of a set of Lambda Unity horns, I'd take a look at the surrounds to be sure that they're intact.

I've heard the original Unity with misco drivers and Pyle PDMR5, albeit in different systems. If there are differences in sound it isn't obvious. They might appear in a close side by side comparison, but there's nothing I could point out right now. The real difference is in build quality. The Pyle is quite obviously cheap. The Celestion that Roger mentions is much better built and I've found that to be true with all their drivers I've used. With the Pyle, the terminals feel like they are about to break off when you bend them, so you have to be careful and gentle, using pointy nose pliers being careful not to apply any pressure to the join. The surrounds are half roll foam which is unfortunate for long term stability and not a good choice for a midrange driver, where an accordion surround better controls cone breakup. So I would say if you want a good one to experiment with, go Pyle. Misco is a better one for long term use. Better still would be the Celestion which has what I consider to be the ideal mix.

Default Visaton M 10 4" midrange

I was just quoted a price of $21 per driver, on a single driver basis. The USA Visaton dealer is checking on what constitutes a box, and what quantity discount structures would be. Stay tuned, and I will post as more information is obtained.

If anyone has a better idea on how to go about this, please PM me. One good thing, there are Visaton distributors world-wide.
