Rat Shck Presidian 40-5053. Next Sonic Impact?

Lack of an inductor in series with the woofer means that they rely on the limited frequency response of the woofer to roll off its HF response. This means that the woofer must not exhibit any wild peaks and dips as it approaches its HF limit. The purpose of the low pass section of a crossover is to keep the woofer signal away from this eratic frequency range. So the success of the full range woofer depends on the characteristics of the driver. A light cheap paper cone is more likely to work well than a metal cone driver, although the metal cone is far superior if properly used.

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
