SEOS Tempest LCR Build for Theatre Room! My second DIY Audio project.

Well I just got notification from Erich that my order of three Jeff Bagby Design SEOS Tempests has shipped!  So I feel like its appropriate to start my build thread!

Proof below!:

Items Ordered | Track your order

This will be my second venture into DIY Audio, my first being a Lilmike's F20.

I was really tempted to order the flat packs but I feel like since this is only my second DIY audio project that I really want to expand and improve on my skills and be able to say that I did it myself!  Luckily one of my Co-Workers has a decent shop setup and he is going to let me use his shop to cut the MDF for my boxes. If I have figured out how to use cutlist properly it looks like I will only need two sheets of MDF so for the price of one of the flat packs I should be able to build all three cabinets.

I plan on using MDF and painting the cabinets with Duratex as I really like the look and these are going behind an AT screen.

Some questions for you guys ahead of time and Is there anything else I need besides what I have listed?:

I have everything I need for soldering the crossovers.

Speaker connectors (I think I will use Speakons.)

Speaker Gasket tape (Do I need this for the horn and the woofer?)

I have hurricane nuts from my F20 build, do I need these or should I just screw the woofer and horn directly into the MDF?

For bracing should I just go with the dowel method?

What about dampening the horn, I see a lot of horn builds were the horn is wrapped with some kind of calk and taped over?

Any other advice will be appreciated.

I look forward to sharing my build progress with the forum!

Thanks!

My care package arrived today and I will echo what everyone else has said, Erichs packaging is excellent!!!!!!!

Here is a crappy cell phone pick:

My friend will be helping me cut the MDF for the boxes on Saturday!

Also to my surprise included in the box of stuff was three strips of speaker gasket for the Wave guides!

Yes yes indeed! Thanks Erich!

While your browsing quick question, The hardware package in with all the crossover stuff there are six threaded rods and nuts which I assume are for mounting the three compression drivers to the Wave Guides. I just want to confirm that I am supposed to use two on each as there are five holes that line up on each one. Just want to make sure I am not missing something and doing it correctly!

Ok , forgive my newbness, here is a picture of my compression driver which has five threaded holes which is causing my confusion:

Safe to assume then that I just use the outermost two?

Thanks I just want to get everything right!

Thanks ack_bk, I hope to take pictures of my progress with each step!

Thanks Bmg!

Just placed my PE order, I purchased some of the barrier terminals for the crossovers and in the end I went with regular binding posts. I used the speakon on my F20 and I like it, but it is bulky. I currently use banana plugs on everything and have had no problems. I guess it came down to that I think the pair of binding posts just looks classier than the bulky plastic of the speakon!

I had been thinking of going with the Duratex however I didn't realize how pricey it was. These are going to be behind an AT screen so I think I will just go with a smooth finish of flat black paint!

Well I have all the wood cut thanks to my friend Dans help!  I am very excited as he had all the right equipment so we were able to Rabbit the edges emulating the flat packs! Should make it nice and easy to glue them up!

I will be gluing the boxes up tomorrow and I need to cut out the openings in the front panel to match the baffle.

I did not realize that Duratex is only available online, I am debating about just finishing them with Kilz oil based primer and then some black satin interior paint that I have leftover from my Theatre bar build. What do you guys think is the Duratex that much better that I should spend the 80.00 on it and wait for it to get here? 

Also in case any body else is building three of these or I guess any of the SEOS with the same dimensions here is the cutlist I used.

Help me choose what glue to use guys.

Here is a test clamp up of one speaker so you can see the tolerances I am working with. Is this close enough for using Tightbond or should I use PL?

I would like to use the tightbond I think so I can unclamp in a reasonable time to move on to the next cab (only have so many clamps.)

My only concern with the tightbond is do you think I will have enough time to put it all together and clamp it up before it sets, I believe I can assemble it in about five minutes.

Thaks guys! The baffle is on there for testing but I will glue it on separately.

Well going back to the table saw is not going to be an option so I think I will just go with the PL then and maybe borrow my buddys brad nailer to assist with holding together.
