New Mark Audio Pluvia Seven

[Squeak]

Perfect build. Just the right amount of handmade rustica to not make it a try-hard. Near exact match of colour of driver and wood.

Got my 7.5 liter reflexes done. Quite happy with how they turned out and sound.

Nice work.

New here and looking to build this box (my first)... Pluvia 7's should be on my doorstep in a week or so! Looking for the slimmest enclosure and this seems to be it. Few questions though...

- Can width be reduced any (to 130mm)? (But maintain internal volume)
- What would the best 'optional bracing' look like for a rear-firing port?

Thanks for any help!

Attached. This time i looked at the actual alignment MA used, i'd have tuned a bit lower, so i revised the wide one and used this tuning for the skinny one.

When one pushes a box skinny you have to worry about early reflections coming thru the cone and giving somewhat of a cupped sound. 140mm is our lower limit for 4" drivers.

Dave,

Thanks for the quick sketch!

If I want a rear-firing port, can I just flip the driver to the back?

Just noticed there's a special price on the version without the dimple @ Oak Audio atm. And I missed the special price on the 12PW

Shouldn't be a problem as long as the port doesn't fire immediately into a rear wall - I'd give them at least 3-4" clearance, or toe them in at least 15dg.

Has anyone modelled any good floorstanding arrangements that are a bit smaller than the pensil? Was hoping for something 36-40" tall, 10" deep and 150mm wide.

If not I'll have to go ahead and model another size. The person I'm building for would appreciate a small slim floorstander.

Wiggle8: the Derwent is on my to-do list. I looks like it fits your criteria. P10 told me the Pluvia is a drop-in replacement for the EL70. Link to plans: http://p10hifi.net/planet10/CSS/EL70/Lake-District-maps-080909.pdf

Dave has a compact floorstander design for EL70 that I"m not sure he's posted - they worked quite well with the CSS driver, and if the Pluvia is a "drop in" (except that driver doesn't need to be rebated) , then it should work like a charm.

Here is a link to a posted picture of the EL70 version (same size exactly) by Bernie in solid yellow cedar: http://www.diyaudio.com/forums/plan...nken-gallery-pictures-only-3.html#post3067780

… and 150mm wide

For the sake of the sonics width needs to be 140+ mm inside.

The floorstanders look very nice. Thanks for sharing the design.

I see the Eminence 12lta in another project. I never liked the way the Radio Shack pod tweeters sounded with them. To me they sound better with compression tweeters.

I'd call the Foster (aka RadioShack) is a compression driver with a fixed horn.

The CFS is another of those formats that lends itself to a range of drivers with appropriate changes in vent tuning. I believe there's a pair in walnut or mahogany veneer from a couple of years ago for the EL70, and I currently have Alpair10P in them as well.

 

[Wiggle8]

I am stuck between the Derwent and the "compact floorstander Mar-KenP7". Both look good to me. They will be used in a larger room but only at low volumes and with "polite" musical genres so not much punchiness is required.

On the Mar-KenP7 is that a slot port in the rear? I can't see any dimensions related to it.

Detailed drawings are part of the paid plan-set.

The vent can optionally be put on the front.

For anyone interested, I'm playing swapping a round a few pairs this afternoon to get a grasp on my new Rotel pre (RC1570) - I think I prefer its Wolfson DAC to whatever is onboard the old Joilda JD603.
Currently listening to the Pluvias in FH3, A7 in Pensil and MAOP7 in FH3. The MAOPs are pretty damned special, but at $90USD /pr ( approx 1/5th the landed cost of the MAOP) the Pluvias performance is IMHO a lot closer to the Alpairs than the CHR or CHN70 and represent a lotta bang for the buck.
