Sealed Statement 2 LCR question

[soundemon]

Having just finished my last build, an LCR of SEOS fusion 12 tempest, I already have my next build in the planning stages. it will be the sealed statement 2s. I have a question though:

If someone had the space (which I do) would it be preferable to build 3 of the sealed statements, using the 3rd one as a horizontal center but with the tweeter rotated by 90 degrees? I'm talking center with the WMTMW layout, full open back mids etc. it's this or the frodaddy style center, I'm not a huge fan of the center with the single mid.

It's here!

I just realized that we don't have the Statements II center channel posted yet. It's exactly what you're asking for except this has sealed mids too for greater placement flexibility. Meniscus does have it available as a kit. The only difference between the Finalist center and the Statements II center is ribbon vs tweeter and the tweeter crossover circuit. It looks like this only 34" wide with the new RS225's. We also have a CAD drawing of the center.

Send me your email address and I'll send it to you. The files are fairly large.

Thanks Jim! Let me ask, what is the logic behind having the 2 mids down below and the tweeter above, instead of having them all in a row like the mains? I know for the ribbon tweet you'd have to change the orientation by 90 degrees. I could see for space saving reasons but if you have room for the full sized one?

It really doesn't have anything to do with the cabinet size.

When you separate the mids with the ribbon/tweeter in the center, you've just created a MTM which narrows off axis dispersion. That's the reason MTM centers are less than optimal for listeners that aren't positioned directly in front of the mid array of drivers. Very low crossover points for the mid to tweeter help to correct the off axis dispersion. Ribbons do not cross low.

The close placement of the mids with the ribbon positioned directly above them creates a point source and much, much better off axis dispersion so listeners can set off axis and lose little if any sound quality. It's also the reason we chose to do sealed mids in the center. The center channel anchors the sound to the screen and doesn't benefit from the expanded sound stage as mains do.

Makes perfect sense. thanks Jim!

I love the stack in this picture - the subwoofer the same width and finish as the center channel. :T

Thanks Beerparty! I had a couple of the original shielded RS225's on the shelf and decided to to create a full sized 40" wide center based on the original sealed Statements cabinet but with sealed mids too and a driver arrangement applicable for a center channel speaker. I have grill frames cut for both the center and the sub waiting to be sprayed black and covered with speaker cloth.

I am really enjoying the sound! I also added an Emotiva UMC-200 surround processor to the home theater side of the system. I like it a lot. great sound and works flawlessly. :T

I have a pair of Statement Monitors in the works and was contemplating the Frodaddy 2rcc as a center channel. I like the slight extra width on your Statement II Center. I also like the Double-Sub cabinet underneath it...What drivers are in the double sub cabinet, and how are they wired/ powered. Is there a build thread or drawings for the Sub Cabinet. Thanks, Philzeemon

If you have a pair of the original RS225's that were shielded, the cabinet is basically a sealed Statement on it's side. Spacing for the drivers is the same as the "regular" cabinet on Curt's website or at Meniscus. If you're using the new RS225's the 34" cabinet is a better fit but they'll work fine in the 40" wide one too. You just end up with a lower "Q".

Sorry, I don't have a build thread for the sub. The drivers are the NLA Tempest-X2's that DIY Cable used top sell. Awesome sub drivers. I wish they were still available. The PE 15" Ultimax are a very nice alternative. The sub cabinet is separated into 2 sealed compartments, each about 95 liters. Total cabinet width is 40" wide. I power them with a Beringher EP4000 amp and an analog active crossover that is also NLA. There are a lot of digital alternatives available that would work well.

Sorry for not having more info but these were kind of one off's I built for myself.

That combo with the Statements II Center Channel and the one-of Double Sub looks great. I'm certain it would sound awesome...will have to look into the Ultimax drivers...Thanks for your speedy reply. Phil

Hi Philzeemon, just wanted to add you can't go wrong with the sealed statement center channel. I've built one and its awesome. I used Jims Cabinet design and Frodaddys Crossovers.

The gears in my mind keep turning,.. Your center channel appears to have a larger sealed cavity for the mids than the Frodaddy design. I have been searching for drawings of this design without success...Your help of direction or a link would be much appreciated....NO RUSH,..my finances are such that affording drivers and x-over components for all of my brainfried ideas and projects is months away!
