DIY SEOS 1099 Build

I want to thank everyone for posting their DIY builds Just a little history.... I just wanted to tell everyone how my build goes, hopefully to inspire more folks to stop wasting money on mass produced sound. This is my 3rd DIY speaker, but my first with a crossover. I have built 2 DIY subs using RE XXX Driver and they DESTROY any of my previous subs. I have an 18" sealed and a 15" ported, both in home made enclosures. The 18" is in a sealed box and the 15" is slot ported. I love it, before the build I was running a Velodyne HGS 15 and 2 12" infinity subs. I am powering the subs with an iNuke6000 and they blow away anything else I have ever seen. I have a hard room to balance for HT. It is 30x24 with 8' ceilings, however both ends are open to the kitchen/entry way. The RE XXX subs work awesome! I realize others have better HT systems, but this is what I made withing my budget, and it is better than the local cinema! I was lacking a little in the "woofer" range, but otherwise I have been very happy. I have 2 JBL old school towers as my "front wide" channel, 2 B&W CDM SE mains, 2 B&W rears and 2 Definitive wide side channels. I am running a big AV123 center currently with the Ninja upgrade kit. I have burnt a cap in this unit twice running an Emotiva amp on my front LCR.

After much reading I decided to try the "Elusive 1099" from DIYSoundGroup as my new Center channels. I was impressed with the quick responses from Erich. I bought the 1099, the flat pack and the crossover kit.
The pieces were all packaged great and arrived safely. The initial fit was great.

This is my first attempt at a crossover, so I welcome any constructive criticism. I will update as the project progresses....

Just sold my current center channel and as soon as elusive is available I will be ordering one.

Going to do a curved build like dtsdig. Using this veneer

Very nice! I am going to go with the standard Duratex...... The grey in my interior is the Duratex sound dampening. Goes on like drywall mud. Not sure if it will make a difference or not, but it is supposed to make the cabinet sound more "solid".

Got my 1099s this past week and will be beginning my build soon also. I didn't order the flat packs... time will tell if that was a mistake . I will be following along with great interest! Good luck and have fun!

I don't have a table saw, so the flat packs were a no brainer. They fit near perfect fit, glued easily and look great.

Unless the flat packs are different, I believe the exterior measurements should be 12.5" wide x 36.25" tall x 14.5" deep.

I have seen a couple different sizes in builds.

Mine are only 12.5" deep. Fatshaft made his 14.5" deep. I did a single baffle, think he did a double. Double really isn't necessary for these.

Frankie I don't have a direct answer to your question, but since most folks are interested in comparing the 1099s to the Fusion Tempests it might be worth reading the impressions from this get together (GTG): Vancouver Summertime GTG Results

The most recently listed dimensions on DIY Sound Group's page (screenshot attached) were what I posted above (14.5" deep), but I am not sure it matters all that much. The crossover has gone through several design iterations, so it's possible that the box dimensions may have done the same. Several people have gone with slightly different variations in dimension and bracing and nobody seems to be complaining

I was at the gtg and I much preferred the 1099 to the tempest. More snap,dynamic, and better midrange. Only thing tempest did better was midbass.

Can someone give my crossover assembly a quick look over. I know it is hard to tell from the pic, but I just want to be sure my coil placement looks good and nothing is backwards.
Thanks to Fatshaft's tux 1099 build for the layout !

Trying out some of the Duratex dampener. Figured I would give it a try since I had to order the Duratex anyhow......reminds me of drywall mud.
No comments on the crossover?

The inductor without the core I would turn and lay flat. All else looks good from what I can see. Good job soldering!

Thanks for the tip, I haven't had a ton of time to read up on crossovers. I'll lay it down this weekend.

I am sure you can find pictures of the magnetic field inductors create. Someone posted it before but I have no idea where, lol.

Just applied the first coat of Duratex....I am impressed, the coverage and texture is fantastic! I used a foam 4" roller for the first coat, I am going to do 2 additional coats with a wider roller.
