S.E.O.S.R. MEGA BUILD - Page 5

Exactly! I am fortunate to have the opportunity to do this now. I would hate to pass it up and not have that opportunity again down the road.

I am in CT. I was just actually talking about that. Once Matt and I get the project finished up, and I can get them set up in the room, I plan to try to hire Mark Seaton to come out and optimize it to my space. We talked about the potential of a GTG the following day once he has finished. I think it would be lots of fun to host some GTGs. We like to entertain and have people around constantly, so the misses is cool right along too!

All that said, I think Andrew's April GTG will be about as good as it gets.

What type of offset would you think?? Matt and I have talked a bit more, and I am going to do exactly what Tux advised...build multiple piece units so that we can try the different configurations out.

Tuning lower actaully works out too. I can tune at like 35hz and still not give much up in the range a bit higher. I only started high because I just don't know when I would use them lower and in an attemp to maxmize output near the cross point ot the subs.

Absolutely correct on the subs. With all 16 adn 4 CV5ks, I am into it for $6500 total. Another few hundred in wood, mindsp, etc, but nothing substantial. In the end, I would have been able to get two and a half captivators, 3 subms, or two JLs, or similar. Not that my builds are as nice, but they certainly won't lack output or extension.

Agreed. What do you like best for port option to achevie it?? I am gonna start building these cabs.


Oh I'm building it

I ordered my SEOS24s last week and put th order in for my 4595 BMS drivers and 16 TD15M today I was just hashing out the detials here to make sure we have the best shot at success. I can't wait til its all here and I can post pics. Hopefully I will have a prototype at Andrews GTG in April.

Exactly, just what we've talked about. I think 10" ports out the back are sick!!

That would be an interesting thing to try out. I think I would try the other options first, and try this as an experiment or contingency. I think I'll run that tune, 5cubes each and a 10" sono out the back of each set of duals. Matt also talked to me about trying angles awya, sort of like the everest does.

Yes I meant 4594s, thank you...didn't even see that typo.

I was loving the idea of 4 18s in each main, but there is enough concern about how the seos24 may measure and what it could mean to me if it dicates a higher xover point. This could make the 18s a problem. If the seos 24s get here and will work with 18s, I may order up a few of them too and try that as well, but for now, I think the 15s are the safest bet. We will be able to test them in vertical and horizontal arrangements and see what works best.

No, no, no....ten cubes per pair, 20 cubes per main. It seems that the feeling is that the TDs will work best in 5 cubes each. The ten cubes will be for the pair on bottom, and ten more for the pair on top. Each will have their own giant 10" port. This way the cabs are fairly modular. A seperate section will be build to house the waveguide so it can suppot the top section and also be able to try offsets. Continuosly modeling though until they arrive. I actually think I like them a bit better in 4 cubes each, so 8 per pair, 16 per main. In 4 cubes per driver, and 1200watts to just the woofers, the 35hz cross...I am seeing about 134db in my model all the way down to about 70hz, high 120s down to 40hz, and pretty usable output all the way down to just below 20hz! It feels like the sweet spot for efficiency, size, excursion control, etc. This would put each main at about 7'5" tall and 2 feet wide I love it, they will stare out at the audience like they want to eat them! They'd be 20" deep as well. If it seems like they want a touch more airspace, I can stuff them a bit too.

Hahahahahaha...for sure, you gotta have the detials!

I have decided that multiples sets of side surrounds may cause more issues in the soundfiled than benefits. I may experiment once its up and running. If a side surround per row works, tahn I'll do it. Unil then, its just 7.16

I wanted to throw this piece out there too....Matt and I have been discussing it, and really feel that multiple rows of side surrounds will effect the sound field in a negativ way. I am going to build one set of side srruonds for now, but have three rows of seating, with just over 7feet beween them each. Does anyone have solutions for for a situation like this, keeping in mind that I will be building these seos24/TD15 surrounds for rear and sides??
we thought simply mounting them a bit higher and angling down toward the lp might help.

no problem Erich, I appreciate you trying! I have put the order in for almost 20 of the AS TD15M woofers, as we thought these would offer the most flex and ability to try different things depending on how the 24s measure. Thanks for trying

If I place them directly to the side of the second row, which is being set as the optimum row of seating, the end seat on either side will be about 3 feet from the face of the speaker. The first row is forward about 7' from there and the third row is back about 7'. The ceiling is going to be high enough that I can place them anywhere from ear height to 4 feet above ear height and still have over a foot from the waveguide to the ceiling. The ceiling height in the second row is going to be almost 9.5 ft

So I have also been looking at some amp options and have one set that I like a lot...wondering what you guys think.

Looking at the Lab Gruppen C series amps.

Mains: Lab c48:4 for the mains woofer sections...up to 1200w x4 (obviously only need three of the channels..seems like a waster, but I really like the lab stuff). The other option, depending on how brave I want to be with excursion and the 48.4, is the 28:4, which will give each woofer section 700w. For the top sections ( 4594 coax), the Lab c10:4, which will give the CDs 250w each)

For the side and rear surrounds, the lab 28:4 will give 400w a piece.

All said and done, my local pro audio installer will give me a nice deal on the Lab stuff and I can be out the door with all three of these for about $6k.

Thoughts??

Looking at the efficiency ratings, cost , form factor and convenience, I am considering the Labs very closely. They should be nearly as efficient as the wyred amps, have remote on/off, won't take up much more rack space(shich isn't really a concern anyway) and will be less $$ for more power.

Also, I am still open to thoughts on the surrounds. I am getting started on the modular cabs for the mains, and would love to start the surrounds soon too. I just want to try to build them according to placement. Thanks guys!
