SEOS 12/AE TD12M Project

I wanted to begin by saying Thank you to everyone that has helped me in making my final decision. My middle name really should be Secondguesser. Erich, Bill, Nate, and everyone else who were involved, Thank you. I also wanted to say Thank you to ChopShop1 and John at AE for executing the GB. I was waffling between the SEOS 15/AE TD15M and the SOES 12/AE TD12M. Although I can easily fit the larger design, I don't believe it is necessary in the room it is going to be used in.

I have placed my order for the AE TD12M's already. I was going to wait a few days for Erich to get caught up before I ordered the SEOS 12 and DNA 360. It will be a little while till I receive the drivers from AE, so I want to iron out the details before then. I wanted to start this thread in an attempt to gather information as well as make sure I was on the right track.

Total: $778.00 for 3-AE TD12M's via the Group Deal.

My first big task is to order parts for the crossovers and assembly. Here is the list as I have it cued at PE. I based these on the passive crossover Bill designed and posted here: http://www.diysoundgroup.com/forum/index.php?topic=74.0

Please let me know if I am missing anything or you have a suggestion.

The plan past that is to order blank front baffles from Erich with the waveguides and cd's. I would rather have the recess for the waveguides cut with the precision I don't have. The woofer recess and slot port is within my skill level. The overall space available for the cabinets is 30" high and 24" in depth and 22" wide. I don't think I will need that much, but it is there if I need it. My next questions are about optimal enclosure volume for the TD12M and tuning. (Note) I currently have a single sealed Titanic 15" on sub duty and have 4- 18" Q's here ready to be built, however have put that build on hold to focus on getting my mains in order. Considering my equipment, I was going to tune to 60Hz. I will have them crossed at 80Hz when the 18"s were in use. Although I will not always have the 18"s fired up. Is this advisable? Has anyone modeled and/or know the optimal enclosure volume for the TD12M? I like the idea of internally separating the waveguide from the woofer and will plan for that and take it into account when ordering the baffle. I also would like to house the crossover in the upper chamber where the waveguide.cd will be I like how RB's turned out and have linked his build below. I understand he had a limitation on cabinet size due to space constraints but I don't have that constraint, thus me asking if there is a more optimized enclosure.

Edit: (3-11-2013)
Ordered the SEOS 12 and DNA360's today just to keep the ball rolling.

I will itemize everything with costs assigned as this progresses as well for those interested.

I also added a link to AV Science Sales 5 (Mike's) to the sources as I have been referencing his build thread a lot.

Running total: $1297.41

Thanks for looking,

Chris

Thanks for the link! I like that slot port placement. That will match my subwoofer enclosures a lot better. I am stuck on wanting a separate chamber for the waveguide/cd and crossover up top. I think it will be easier to access the crossover if I need to as well as giving the TD12M its own enclosure. Am I over thinking this? I hate when my mind gets stuck on a detail like this.

I was going to pick the appropriately sized baffle and build the enclosure around it. If Erich had a flat pack already, Similar to Mike's enclosure, I would save the time and go that route for sure.I will shoot him an email and see if there is a time frame on something along those lines. I am good with the single common chamber if there is no benefit from them being separate.

I just went to submit my order with PE and the gold plated binding posts I want are on back order. I am going to order them anyway. They are due back in stock before the AE drivers will ship, so I will keep my fingers crossed..

Edit: $134.68 for all the parts in my first post with a $5off coupon. Not too shabby.

Erich, I feel like I am beating you up man. I appreciate your patience as I make these decisions. The main reason I wanted to do slot ports was to match my subwoofer enclosures. I an going to run everything across the front wall under my tv as this room is limiting placement. If you picture 4 Captivator's across the front. (L)(SUB)(SUB)(C)(SUB)(SUB)(R) or (SUB)(L)(SUB)(C)(SUB)(R)(SUB) all with slot ports. I just think it would look cool when all the grills are removed.

Is there an example on the site to give me an idea of what the round ports would look like? Maybe like the Fusion-12 Tempest? If the LCR's end up with grills, I will be doing all the work for nothing. I can't keep grills on the sub, so I won't bother with those. My son likes to watch the driver move, so he pulls the grill off. He doesn't seem interested in the mains.

I currently have Cerwin Vega VS-120's for L&R's. It takes a lot of volume to get them moving as well. More volume than I will do with him in the room. I am glad he will be bored with them.

Side story, I grabbed one of his banana stickers and stuck it on the Titanic's cone. He absolutely loves watching it. He points at the sub and says boom boom if it isn't on. Definitely no denying he is mine.

Thank you Mike. I will keep that in mind if I stick with that plan. Also, Thank you for sharing your build. I know all too well the value of time.

I went back and forth, the end decision came down to me being able to get the output and response I want in my room with the smaller, cheaper, and less intensive option. Before the AE GB Chop set up, I had already been in contact with Erich several times about the Sentinel. The GB put another option in reach and swayed me into the unknown, for me at least. I am crossing my fingers that I made the right decision based upon others experience and input. I am confident I will have some size envy when your drivers come in. I look forward to seeing your build.

Thanks RB! I know absolutely nothing about tuning and F3 results less the general movement you described. My time to do research usually lasts about 10 minutes before my son realizes he does not have my attention. And then there is Yo Gabba Gabba. I am wondering if the kit Erich has in mind has a specific tuning/F3 based upon an "optimal" configuration? I don't mind tuning higher as I will have plenty of firepower down low. I can always turn the subs down when needed.

I appreciate the offer for your help as well. I am going to wait and see what Erich has up his sleeve before I pull the trigger on which enclosure to go with.

Thank you for your input John. Would you please elaborate on your comment, "ideally lower?" As I am still in the planning phase of this, so I can build whatever I want.

Until I make a decision on the enclosure, I wanted to make some kind of forward movement. I ordered 3- SEOS 12's in plastic and 3- DNA360's today. Add $328.58 to my running total for those that are tracking cost.
