A bit of an update…all of the mark audio drivers I wish to try r on back order….the pluvia 7hd is at the,top of the list although the chp70 and especially the  90’s look interesting…other ones r the fostex fe108ns and any of the scanspeak 4 inch discovery line look like contenders….rthe scanspeaks r only ones in stock I believe….for now I removed the w8-1808 ‘s. and replaced them with and old pair of omega rs7’s….sound great…the tang bands seem a bit muddled in comparrison…t…the rs7’s still sound better in the old snell E cabinets where they have languished for years in my closet….bit still quite nice in ob….so kinda stymied for the moment….any new thoughts out there….?

….the pluvia 7hd, chp70, CHP90, fostex fe108ns, scanspeak 4 inch discovery line

The Pluvia and the CHP90 would be my top choices, they are quite different, the CHP needs a bigger box, goes lower, and is a bit more laid back.

CHP70 is voiced for the Japanese market with an elevate midrange. Usually not to western tastes

FE108ns will want a horn. Haven’t heard them but if anything like the FE108e∑ or other fostex of simialr size will be more romantic with potentially some shout.

I’ve heard one of the 3” Scans, sometimes people think they are 4”. Quite neutral, very pricey.

They look like almost  totally different drivers…may be forced to buy them both…the sacrifices we make for audio….

Is this the Scanspeak Discovery 3"-4" full range model Dave and OP referred to?

The Coral Holey Basket alnico's would be a great choice. They aren't hard to find and can be had for around a $100 a pair.

You may wish to consider the LGK driver from GR Research.  For your listening tastes and near field distance, they might work very nicely, and they are quite reasonably priced.

Here is a link:

They are special, but they tend to get SSS (Stiff Surround Syndrome). No-one has yet figured out how to unstiffen them, but if they suffer they still make a decent midTweeter,


Never paid more than $10 for a pair. The ones from Monarch that came a pair of 16Ω  to the box was my favorite source.

There are currently three pair of Coral Holey Baskets ( aka FE103A ) on eBay from different venders at $169- $175 a pair. The surrounds of my pair are not stiff at all. Every one of my vintage drivers with alnico motors so far have been winners. A few months back Madisound had their anniversary FE103A alnico editions priced at a whopping $750. There's a lengthy thread on the CHB's at HiFi Haven.

The pluvia 7hd’s have arrived and have about 100 hours on them…quite different sounding drivers….the 7’s r very open, fast and clear, great soundstage…..rising spl doesnt bother me actually probably an advantage….as I cant hear above10000 anyway…the 10p were musical right out of the box… more meat on the bones than the 7hd’s…..soundstage is not as open and deep but more forward nd involving if u will……u feel a part of it not just looking at it….will go back and forth for awhile but as of now the 10p’s r more to my liking…..

Been interesting so far…. didnt expect this….thought I would like the 10p better …. Turns out I like the 7’s more….perhaps the 10p’s need more break in time….have not opened up yet… still a bit speaker bound ….with a flatter soundstage….not nearly as clear….overall the pluvias are quite impressive…thanks for the recommendation   Dave…any experience with the seas h1304’s…?

A10p has a “vintage” top end, very well controlled, some would say too controlled and lacking top.

A7.3eN ismy favourite of the MA i have heard. Part of that treatment seems to help tame the top end, a common complaint.
