Guys n gals,

Just got a quick question.

Front speakers in the new system are Dyn 362's and I'm setting them up the same as the x-trail. Yes, I know its not everyones 'ideal' setup but it does what I want...

Anyway, Im getting some dyn's to act as a centre channel (end goal being 5.1 like I was supposed to with the xtrail) but im not sure whether to use the MD-102/142 combo as the centre, to match the left and right speakers already on the dash or should I use a larger mid/tweet combo such as half a 222 component set?

As far as the likely planned power goes, the front left and right will be running off a bridged Arc KAR 300.4 and the centre/ rears will be running off the same. Centre probably bridged and rears running off their own channels.

Basically, will the three inch mid adn tweeter be fine for centre channel duties or should I use something larger?

Peace..

Woody

'Larger'. Simply because the centre channel is required for so much 'information' (bandwidth) in a 5.1 recording, including the crucial vocals. Something that can play comfortably down to 250Hz would be good, and the Dyn MD142 simply isn't designed to go that low.

Thanks Shiny.

Just out of interest sakes, what do you use for centre?

I have a 4" 'cone' (as opposed to dome) Morel driver, and no tweeter. It's in its own tiny sealed enclosure, and bandwidthed between about 200Hz up to 1.5kHz, there-abouts from memory, so it focuses only on vocals. But that's for standard 'stereo' music, and not dedicated 5.1 recordings, and the volume is turned way, way down, so most people wouldn't notice it.

In the previous car, which was set up for 5.1, I also had the matching tweeter (and passive crossover), so it catered better for proper 5.1 recordings, and was HP'd at around 200Hz.

Even 200Hz is higher than optimal, so if you can fit something like a 5.25" 2-way set in the dash, and have it play down to 100Hz, that would be perfect.

If you are willing to step away from Dyn for the centre channel, I'd go with something like a 3~4" wideband (cone) driver. You'd expect that to play down to 200Hz fine, and also cater for the treble just fine, and be easier to install.
