Rat Shck Presidian 40-5053. Next Sonic Impact?

Mounting both drivers on a planar surface yet featuring a first-order crossover on the tweeter and no crossover on the mid-woofer is no doubt a feature designed to help optimize placement. If the speaker is placed horizontally (with the tweeter closer to the center) a slight toe-in will time-align the drivers. You'll know when you've hit the right amount of toe-in when the image "snaps" into focus. I'm almost positive this is what Rat Shack intended.

Bring on the 7 1/2' array!!!

So what are we gonna use for the bottom octive-and-a-half?

What's the sensitivity on these. Anyone try them with a Sonic Impact amp?

I'm thinking about trying this arry idea. I don't know much about arrays. I guy at work says that 14 per side wouldn't work. He says you can't wire them in series as it would double the ohms every speaker, etc.

I don't understand what in the hell he's talking about. Would someone mind explaining it to me and how I should hook these up together.

Thanks

Drubin,

I own the Ref. 3A DeCapos and these Presidians. There is no confusing the two! BTW, My Decapos which supposedly "have a single cap" on the tweeter, actually have 4 components in the crossover. It's strange: When I enquired with Divergent Technologies (Distributor for Ref 3A) they said there is "effectively" a single cap on the tweeter. Whatever that means!

Enjoy,

TIC

when i found my vintage hartley monitors, the crossover was the same, a single cap to an older cone tweeter with the mid-woofer running "wide open." the response of my friend who dabbles in speaker design was "ugh." the new tweeters and crossovers from hartley have three components (now four, i added a bypass cap), and the sound is now very acceptable to my tin ears. a similar upgrade for these little puppies naturally springs to mind.

funny about the deCapos and the use of language. sign o' the times......
