The new Elite recievers offer the Marvell Qdeo video processing, which I believe, the SC-25/27 do not. If you watch netflix or other internet video, this processing could be an important factor.
Hi Guys, Will be building a sealed Sonosub; my current box sub has too many sharp corners for my kids to possibly run into. Have 18" sonotube will be a little over 16.5 inches high. Any concerns I need to be aware of regarding this project? I have seen few sealed subs of this type. I...
I hope you enjoy your new hobby. But beware, be prepared for the wife's questions, like, 'do you really NEED that tool to make your...(whatever)? pretty soon your contractor saw will not be enough and you'll want a router, planer, jointer, and clamps. you can never have enough clamps
Thought I'd post my questions here since it's about LT and I didn't want to start another thread. I'm currently running Atlas 15 sealed, 3.7ft^3, Qts .37, Qtc .707, 250W Rythmik Amp. WAF has gone way down since I built it last January (I was the guy who blew up one). Been modeling LT (Qts...
Wad, I just finished a sub using the Atlas 15 and 250W Rythmik Audio Amp. I used a sealed design. 4.12Ft^3 no stuffing. For $35 more, you get XBL^2 driver, plus it looks coooel! These drivers are made to jam without lots of power. This sub rocks! With the 350, oh man. I can only imagine. I...
I have a dado set for my table saw and a biscuit joiner which help not only with lining up but also with more surface area for the glue. These are not required, just nice to have. Wood glue is all you need. The screws will hold the wood tight until the glue sets. It is very strong when dry...
Yup, regular wood glue. Yellow glue. Any of the yellow wod glues will work. I use Titebond only because I've been using it for several years now. There's Gorilla Glue; Supposed to be the next great thing. I haven't used it though. Way more expensive than regular wood glue. Maybe someone else...
Do you have any clamps? I used a combination of clamps, screws, and biscuits to hold everything together until the glue dries. If you have few clamps, use screws to hold it together until the glue dries. Then, remove the screws and fill the holes with wood filler. Just go slowly, take your...
The AVR (Pioneer VSX-509S) will increase/decrease the sub's volume. I'm thinking it's a calibration thing. I still haven't had time (read: wife and baby in the house) to properly calibrate the sub. My system will play loud, but the test tones at calibration levels bug the wife. Go figure. What's...
Well, glad to see I'm not crazy. No boost on the amp. This project was basic; now I need to get some help with the auto-on signal. The output signal from the AVR to the sub, does it increase or decrease as I adjust the level when calibrating? I can't figure out why the sub won't/can't auto-power...
My living room is about 2300 ft^3, but it's open to the kitchen and the rest of the house. Using Vance Dickason's book, I calculated Fc. I used boxplot to get F3. But I used the book again to calculate F3, and got 41.08. In other words, Fc=F3. Is this right? Maybe my math is wrong. Two...
Simulations indicate Fc of 41.08 and -3dB of 31.07. I went sealed for the SQ. Wanted extension, but was willing to sacrifice it for SQ. Well, not anymore! But room gain indicates -3dB is somewhere else. My preliminary measurements @ 16Hz 94dB. Fc seems about right, though. :D I can tell...
I was able to get a quick test tone measurement done while the wife took our baby for a walk. (read: 30 minutes). These are uncorrected values 10 Hz, 63dB; 16 Hz 83; 20 89; 25 92; 30 99; 35 92; 40 98; 45 96; 50 92; 55 97; 60 96; 63 96; 70 89; 80 98. Corrected Values 16 94.5; 20 96.5; 25...
Could I add an LT to my amp? It's the Rythmik 250. What other options do I have for adding an LT? How much smaller could the enclosure be with the LT? My living room is about 2300 ft^3, but it's open to the kitchen and the rest of the house.
The story here started on another thread last week, and I should've started a new thread then. Received the Atlas 15 Tuesday. Came home and connected it up as per instructions, calibrated it, and fired it up! :D Well, with the 4 ohm amp powering the 4 ohm Atlas, oh man, what a sweet sound. I...
Despite my wiring errors, this sub can jam. Put in the Pod Race scene--not even a sweat. I put my hand next to the cone and it was hardly moving. My current HT speaker setup is all Polk: RTi 38 mains CSi 30 center FXi 30 surround With the addition of the Atlas it was awesome:D I was...
Thanks Chad. I put a jumper across the gold terminals to remind me of the correct wiring :b My wife told me that it figures I would do something no one else has tried to do. The THX levels, only a minute or two though.:D
It figures. The one page from your web site I didn't print out was the wiring fo the Atlas. :frowning: The gold terminals looked sooo cool. I guess I was so excited to get everything put together and powered up I goofed. I even forgot to put a jumper across the other terminals. I'll...
I don't think it was wired incorrectly; I checked and double checked before I sealed everything up. And, it was working fine for a while yesterday and today.:)
I finished the enclosure yesterday and put everything together. Sweet! Fired it up, and wow, what a sound. Just like it should be for a subwoofer: not really notice it when it's on, but notice more when it's not. Played it for a while today before calibrating it with the rest of my HT. Pod...
The driver and amp arrived last friday. I began building the enclosure the same day. Chad mentioned that 3.7ft^3 with stuffing, or just over 4 ft^3 without. I came up with a 4.12 ft^3 enclosure; sides measure about 22 inches. Anyway, if I need a smaller box after measuring SPL, that's ok...
Modeling these XBL^2 drivers is kinda difficult. I emailed Chad yesterday about enclosure sizes and Q, and also about using the Rythmik 250 from Kyle. I thought sharing this on the forum might be beneficial since some of this info is not up on his website yet. "Recommended enclsoure sizes...
I have been reading this forum for over 2 years now, always drooling when new projects start. Well, Santa was good to me this year, and I'm building a 104 l enclosure with an Atlas 15, with a Rythmik 250A from Kyle :D As I start this project, I just want to thank all of you who have posted...
