RAAL 140-15D Group Buy

I am putting the feelers out to see if there is interest in a group buy. I hope I am not in violation of the forum rules by posting it here.

Hi Guys

I'm interested in gathering a group by for Australia of the RAAL 70-10. Discount is about 25% off US$300 = approx US$225 = approx AU$250.

This is a rare opportunity to grab a versatile ribbon tweater for the price of a danish dynamic driver!

If anyones' interest please let me know!

(After researching both the 70-10 and 140-50, i've found the 70-10 is more versatile for various projects. The 140-50 is just too big for a coherent crossover over 1.8khz)

Hi Volvo,

Is 140-50 a new product? Can only find 140-15D.
You mention about 70-10 being more versatile, well the recommended crossover is 4th order L-R @ 2800 Hz. The 140-15D is 4th order L-R @ 1600 Hz which to me is more versatile.

The 70-10 is only 95mm in diameter, whereas the 140-50D is almost 7 inches long.

Because the 140-50D is so big, there are fewer dynamic drivers it can be crossed with and still be in phase, as the distance between the two drivers is much bigger than normal.

x-over of 4th order at 2800hz sounds steep, but with an initial low-Q slope, intergration is still seamless as a second order x-over.

The 70-10 is the same size as most conventional dynamic tweaters, with similar parameters. Therefore, it can be easily implemented into conventional dynamic speakers with little modifications.

correction, i mean the 140-15D

Chris,

Is the US group buy still on?

Volvo_Victim · 5th November 2007, 01:58 AM

also the 70-10 is also about US$180 cheaper PER UNIT compared to the 140-15D
