I will be powering up the twins tonight. Going to set them up with the spl meeter and run some test. Only one problem, I cant decide what scene to try first.

With the 15Hz extension you have, Scott Pilgrim's amp vs amp scene is a good one, or the Terminator Salvation gas station scene, or reviving Megatron from TF2 are good ones. if you are high passed well, The Incredible Hulk's Sonic Cannon scene will move you.

They ended up being 4.40- 4.50 internal volume taking into account the port and driver, bracing. 30X20x17.5 external size.single 4inch port 22inches long not including the flaired portions. and are tuned to 16.5-17.5. i will be running the Eq2 as a eq and high pass at around 14. but that will need to be played with. then i added a high pass in winisd that seemed to look good. and then will probably just even aout any peaks and do a little house curve. I hope they perform well. I will be messing with them in an hour or so and let everyone know how it all turns out within the next few days. cant wait to get home.

i dont have a router so the port butts up from behind and then I used a course file and sandpaper to mold the outer port flair.

Well I will let you all know how I feel about these in a few days. But I will say these slay my a2300 and I will never purchase a premade sub again. And yes the TF2 scene above has notes I have never felt or heard before. Until now:D

I couldn't tell from your pic that you posted but can you disable the HPF that's built into the ed lt-200 plate amp or do you know what the HPF is set at? I modeled your sub with your specs to see how it looked and a 16Hz 3rd order HPF seemed to be perfect.

If you start from where Ravage lands on the container ship, it is a good ride up until Megatron knees Starscream in the chest. That one hit extends down to 10Hz. Best part is as the 'doctor' approaches Megatron prior to reviving him. Strong ~20Hz there...

TF2 has lots of great scenes for 15Hz extension. Check out when the pillars fall on the d-cons after the tanks open fire in the desert. Good stuff.

The pillars falling was the one that made my son smile. We watched at -18 so I really havent unleashed there full potential. My son is 12 and helped throughout the build. He was pretty proud when those scenes shook him. Even he said they don't even sound like they are trying they just sound so much more real than the a2300.

THAT is some good stuff there.

Glad you re enjoying your build!

Thanks he is really into it. He even tries to guess what Hz scenes are and will have me get on here to find out what Hz they hit.

I have had some time to watch a couple movies and throw some of the torture scenes at these. So far they have past everything I have thrown at them. I haven't had to use the hpf on the eq2 but the Amps have a hpf just not100% sure when it kicks in or at what Hz. After all was said and done I have a total of $140.00 into each one. I never dreamed these would perform so well for so little. Last night I played some of the train scenes from polar express. My 2300 hatred this movie. These just wanted more. My room has never sounded of shook like this before. No port noise or signs of stress just loud clean bass. Played back some of the scenes in 9 and same thing these just pounded me and my room. I still need to eq them a little but I am just enjoying them for now. Thanks to everyone that helped along the way.

Chalk up another happy DIY customer. smile.gif

Great to hear your impressions.

I have added the A2300 to the left rear corner. It does sound ok with the fronts but if I go to high with the gain it draws attention to its self but after some fiddling I have it integrated pretty well. It will be a while before I get the diy subs in each back corner but for now these are still pretty impressive.

Sold the a2300 and bought 2 more 1260w's and a epx2000 to power them all. The fun will begin in a couple weeks.

My son and I spent the weekend working on the 2 rear subwoofer boxes. They are a 3.9cf internal volume and tuned to just under 17hz. was a little restricted on size bit needed to get them as close to the fronts we built as possible. Just need to round over the outer edges and port hole. Then get them painted. The wire should be here Thursday so we should have them all up and running. Friday night we will get them all calibrated and then hope to watch a full move on Saturday. Cant wait to let all four of these rip.

Just a little test fit before the drivers go in and get wired up. Will be running both channels of the epx2000 at 2ohms. To power these and the front two. [IMG]]

Great progress so far smile.gif
A perfect example what you can do with a little bit of cash, and some patience.
Those 1260's really are great drivers for the money... I can't recall how many times I've recommended them.

I got them going late last night so i couldnt really run them hard but tonight i will be able to dial them in a little more and acually turn it up. One thing for sure, I am going to have to do a fan mod. I would hate to hear the ep series if these are the quiter of the two. Any comments or tips would be great.

Had a chance to mess with them and they all do pretty well together. Still need to really calibrate and eq them but definitely gives me more punch and shake. My back row seating still isn't as powerful as the front so I have to play around and see if I can that figured out. If I move forward about a foot the bass Is noticeably stronger. Played some scenes from 9 and my pants started flapping so I'm on the right track.

Got my fans ordered. The ones they come with are more then I can handle. Haven't even watched a full movie yet because these fans now just kill the mood for me. I ordered the 26cfm and 19db.
post #56 of 61
Thread Starter 
So for anyone interested.... These things are pretty darn crazy. My son and I did the fan mod this morning and then calibrated all the new subs to the others and mains. The amp is a epx2000 that is running each channel at a 2 ohm load. The new fans are 19 db 26cfm and the amp stayed cooler than my receiver during the hulk movie. Useing the tones in the receiver I am 6 db hot .But when useing the Disney WOW It claims I am 12db hot. But it sounds pretty balanced with the mains that hot. The 2 rows of seating in my room are now pretty close SPL wise. Before the new rear subs it was a lot louder on the front row. The amp is now running a single RCA in and set to mono. On the amp I set the rear subs 4 clicks lower that the front which is at max. I have the subsonic filter at about 10hz and had no trouble with the hulk. No port noise, bottoming out or unloading. Never sounding stressed or being pushed to the max. The sound gun scene was great. The 50 cals sounded and felt amazing. Final fight scene was brutal. It pounded the hell out of my room and finally had that shake the hell out of you that I have been shooting for. I can finally say I am satisfied with the LFE in my room.

Great thread, thanks for sharing! I, too, built a few 1260w subs and they really do perform well for the money.
post #58 of 61
Thread Starter 
Thank you. The best part is I only have a little over $500.00 for all 4 with amp and materials to build. I still have to cover them in something. Might go with rustolium deck restorer but still deciding on that. Just think if it wasn't for this site and all the crazy builds I would have been happy with one store bought 12.

Final coat all done. Rustolium bed coating in spray can. I'm happy with the way they turned out. And would recommend DIY to anyone I thought was somewhat handy.
