Default New Mark Audio Pluvia Seven

Well the new Mark Audio Pluvia Seven Gray/Gold cone 4" Full range drivers are available at Madisonsound here in the good old USA! $45.00 per speaker, so they are middle of the road price wise with the CHR70's and Alpair7's. I read the description promoting them as an improved version of the CHR70's, and that they are not recommended for vented enclosures? This stuck me as an odd characteristic for an improved CHR70, which can be used in a variety of alignments? No published box plans on the Madison site yet, so I guess those are in the mill?? Here;s the Madison link:

Mark sent us early Pluvia Seven (CHS-70) so that we could provide feedback on the new basket (which is quite nice). Ours are marked UK version. They work well in Frugel-Horn Mk3 (all we have tried it in). I'd say well worth the extra cash over the CHR-70. I suspect the dimple in the dustcap is a contributing factor to a smoother top end.

I just did a bunch of sims. Sealed (7.6 litre/butterworth) you are going to get 90 Hz F3, 50 Hz F10. I tried it vented (4.7 to 13 litre) and (with my alignment) i get F10 as low as 40 Hz, the smaller boxes near 50 Hz but with an earlier start to the roll-off. Almost as low as the A10.3. Much like the EL70 in terms of alignments.

Note: like all the other current MA the grey/gold is really silver/copper.

The Qts of 0.53 is the alleged reason why it is "not recommended for ported enclosures". Strange since this is about the same as the A7 and CHR.

Nice thin frame, means less or no routing. Perfect for a lazy man like me.
Isn't that Qts about perfect for an MLTL?

Dave, I kinda figured you guys had something in the works for this new driver. Probably a little bit of a tall order to gin up two to three designs when you get the speakers shortly before they are are available to the masses? I for one look forward to maybe a Pencil Design or something along those lines in the future. Good luck and great success in all your endeavors as always.

Mac -like Dave says they work quite nicely in FH3, and no doubt messrs D & L have a couple of ideas, if not full sims in the works

Doesn't need any rebating for flush mounting, but note that mounting holes are in a five hole pattern, so even if it fits the same through hole as CHN70, it wouldn't be a direct drop-in replacement.

Hey Dave,

After spending some time listening to my son's FH3s (previously FF105WK, since Christmas Alpair 7), I've decided to ditch my multi-way aspirations (for now) and try a more-or-less proven FR design. Problem is I can't locate the speakers more than a few inches from the wall due to my living room layout, so the FHs are out. After scouring your site and others, the Derwents drew my attention as having a good balance of performance and form factor (i.e., small). Of course the EL70s are no longer available. I know the Pluvia's TS parameters don't really match the EL70's, but could the Derwent be tweaked to achieve comparable performance with the Pluvia, or is there another MA driver that's a more suitable replacement for the EL70 in the Derwent?

I could ask Scott if he could tweak Derwent for the pluvia… i also have a set of EL70eN (customer hasn't picked them up/2 yrs now).

If you can angle the FH3 somewhat, a couple inches from the wall is fine. Borrow your son's and try them. They are much deeper than Derwent thou.
