Re: Flex Your PCD Mettle:
I too am inpressed with the RS28F's abilities down low. It looks like we'll have at least two variants to compare on the QSC guide, the RS28F and the SB29. I'd have to say in this application i'll pass on the DX25 as we're going to have to cross lower than 2k to match the directivity of the WG to the 10" midwoofer and the DX25 ain't so pretty below 2k distortion wise. It IS a budget minded option though as it's about half the price of the RS and SB. I do have two of the QSC guides if someone want's to donate a DX25 for adapting. The waveguide DOES have the ability to make the dome perform much more efficiently in the lower ocatve and HD does drop considerably....all of which can be seen in Zaph's original work with the 27TDFC and the 6.5" MCM guide. Can it clean up the DX? Only measurements can tell. It does handle quite a bit of power, that's for sure.
I've been relatively excited about this type of 2way for quite some time and Zilch's measurments of the Deltalight 10" confirm what i've been hoping....a high efficiency,high power handling, low HD and relatively flat inexpensive 10" pro woofer is available for an acceptably sized two way.....and it'll extend below THX spec in a fairly small ported box to boot! Imagine the capabilities of said 2way with an inexpensive 5.1 AVR.
