Creative Sound FR125

[londondan]

Hi All,

wanted to start this thread to see if any one has had any build experience with the CCS FR125 full range drive unit. (you can download the data sheet from madaboutsound.com).

I use a set of KT88 monoblocks, and I am now convinced that passive cross overs, degrade sound, and dissipate power overwise used in moving speaker mass.

Has any one used these in a transmission line or open baffle arrangement in particular?

I have four in the bipolar bipoles from planet ten
Hard to believe the bass they make this is a good speaker for your amp.No tweeter needed

I use four of the WR 125's in this configuration along with a helper tweeter. They are quite good. The center woofer is optional with those boxes.

Hello,

someone used it in my KORNETT double horn with helper tweeter,
feedback in german on my HP.

Hello,

i use it in my "dipol 08" open baffle design.

Cheers

Dear All, thanks for the replies

Cal, what frequency have you tuned your boxs to?

Big Fishe, any photo or links would be great.

All the best Guys........

I have a pair in some Bibs, they're very nice. Bigger Is Better 'BIB' Cabinet Dimensions - ZillaSpeak.com

I used inferior unsuitable wood (it was free) and they still sound great to me. Built properly I'm sure they would sound even better. They need to be in the room corners to do their thing properly though.

Hey Cal, how far back from those things do you sit? I built a pair of changs, and they only sounded good in a big room when you could back up from them a ways. I figured it for a dual-mouth BVR thing. Any thoughts on the matter?

Hi -- I've used the FR125 in a number of applications. Upshot is that it's one of the driver's I'd recommend to someone looking to explore full-range. When they're in the right cab and set-up right, the full-range magic is definately there. Enough bass to not neccessarily require a sub, great midrange, and to many ears doesn't require a tweeter. Downside in my experience is that it's difficult to extract the full bass potential of the driver -- without sufficient damping it can hit it's excursion limits in ways that aren't pretty. Because of the bass potential of the driver it's tempting to push it to the limits... but in my experience I've found that aiming for best driver "control" yields the best results. In short, go for controlled, as opposed to lowest, bass. I've had best results with some sort of resistive loading, such as a foam-stuffed vent. Dave Dlugos et al/Planet 10's onken designs are good; here's my take on one of Planet 10's designs using a resistive vent; in next generation I would put the resistive vent in the base of the cab, which would facilitate optimizing the vent damping/tuning:
Best, John

I've got them in Dave's original mini-Onken. Agree with the others, good fullrange sound with surprising (in a good way) bass.
