Subwoofers / Speakers

I read on a thread on here that a sub with say 90 sensitivity rated 500rms would be louder (on the meter atleast) than a sub with a 85 sensitivity rated 1000 rms. are there other factor involved in this besides sensitivity. like excursion, that would affect which one is louder. I ask because I was wonderin around on ebay and saw a sub called a AA Bass15 (I'm sure its not the same AA that some ppl on here use) and it has a sensitivity of 96 db rated 450/900. Thinking about the whole double power gains 3 db rule, mathematically it seems like this would be better than my audiopulse axis with 87db sensitivity rated 2500rms, but it does mid to high 40's. would that little e…

I'd like to get the boards opinions on them. Are they hard to build correctly?

i noticed all the DC subs are 'FEA' designed.. what does it mean, any got an article on it? thanks

Got 2 Fi 18" Got 2 Saz-1500d 1 capacitor 1battery Starting my system anything i am missing for the sub. If you have any suggestion please let me know Thank you

I'm going to SHOOT YOU! YOU DRIVE ME FREAKING CRAZY! YOU AND YOUR DAMN 15" WOOFER.... Anyone want to see a side by side, box by box comparison of a XXX15 AND a Mag 15??? Call me crazy....... But I just might have the funds and the ability to do so.... My question is...do you think there is enough interest to do this..how many people would want to see this?? It'll all be in the same car..with the same power and the same enclosure environment..... Tests will be ran with all sorts of different music in an attempt to appeal to the typical user..tests will include various boxes and tuning, different music, the LOW END, excursion pictures, and MAYBE some SPL.... What do you thi…

Ok, so assuming I had 2,000 or 2500 watts (1ohm) and a 2.4 CF box 1 12 Xcon Ported or 2 12 Icons Sealed?? Which would be louder? If you need anymore info let me know

Currently have two RF T2D412 in 4 cube ported box in my 04 Dodge Durango. I am running them with two RF T1500bd-cp. Have extra battery and a 270a alt ran with all 1/0. The subs get loud and i have been served well by them. That being said they are not the most musical subs in the world and I have been eyeballing the XCONs for a long time now. Im going to sell the box and subs i have now and get new subs at tax time. So here is my question, are the XCONs my best bet with the power im running. At two ohms I SHOULD be around 1600w per sub. Also in that vehicle with that setup what size box should I build and how much port area is ideal? Would love input from anyone willing t…

I have audioque 2200d and i was wondering what subwoofer setup would get louder? The sub i have right now is a xcon 18 the box is a 5 cubic feet,the other woofers i have in mind are 2 new 12inch icon`s both setups will be ran off the same amp..It is a trunk setup.Thanks for any info..

Unfortunatly I can't take any credit for the design of this box (but Decware.com can) I only take credit for 12 hours of labor building the thing. Keep in mind this is for a HT Those are a pair of a/d/s/ 3 series, sweet little drivers but I'd like to see some RLI's in there. First impressions of build: WAY harder to build than anyother box I've done so far. But seeing how this is my 5 or sixth box (ever) depending on how you count, I'm not doing too bad. Freaking rad design, I nod my head to the guys over at decware. How does it sound, well pretty good, I only had a few mins with it this morning before work. I'm not sure it is as accurate as possible but that could very …

I have a single cab 2008 Chevy Silverado with 2 Memphis 12's but have them in a tiny box. I've been looking for 10's that would suit my needs and have been thinking about 1 Fi SSD 10" but now might go ahead for 2 Mach5 Audio IXL 10's. Are these subs good?(Quality & Loudness). How big should each sub get tuned to 34 Hz? Thanks in advance!

ok im going to be buying 2 fi bl 12" fully loaded an im gonna run them off a aq2200d amp. 2.5 cubes per sub tuned between 32-34. so i wanna get some components for my front doors but im gonna have 2200 watts of bass an i wanna be able to hear all the vocals. which ever speakers i get they will be runnin off a alpine mrp f300 amp. the amp will be bridged givin the speakers 150 watts each. now i was lookin at both of these. http://www.sonicelectronix.com/item_9128_JBL+C608GTi-mkII.html?utm_source=froogle&utm_medium=organic&utm_campaign=froogle http://www.woofersetc.com/p6201/CTX65CS--Image-Dynamics-65%22-Component-Speaker-System.htm any recommendations? budget is …

Has anyone heard the new memphis Mojo's? If so, how do they sound and what would/could you compare them to?

I spy a few of these on e-bay this morning! $175 each! I understand they are also a LMT design! Good price! I might pick one up and check it out! BTW anyone know why in the Book headings for Eclipse it say's a 4ohm SVC... In the specs it says 3ohms DCR(?) DRC(?)

I want to buy two 18" ZCONS but don't know how good they are. Can anyone tell me how good they are? I know their brand new but does anyone know anyone that has had experience with them because I dont like to be the first to give a review on things. Is is mostly SQ or SPL? Im not doing this for competition its just daily driver with extra bump! thanks

hey guys i have a quick question i recently built a box for two zcon 12 inch subs. it consists of a single 6 inch aero tuned to 37 hz only 9 inches depth in a enclosure 5.46 after sub displacement it seems like the sub closest to the port is unloading or sounds Blown at frequencies higher then 40 hz but the one on the left doesn't do this.. could it be the encloser is causing the sub to unload and sound distorted? i had designed a different box which would be a slot port with these specs gross volume 6.98 ft^3 port volume : 1.43ft^3 physical port length 20.00" port bends : no Baffle displacement : 0.19ft^3 port area range 60-80in^2 port area 81in^2 port area per ft: 16.2…

Hey guys. I finally blew my alpine type R 15 after 4 years. Had my alpine mrd m1005 running to it in a sealed enclosure. It was loud and got 141.4 db at a local comp I did just for fun to see how loud I could get. Time for a new 15 to replace it. I'm wondering if anyone knows a good 15" that compares to the type r or better that will run off that 1000 rms nicely. Many of the subs I like seem to be made for ported enclosures. I'm not against ported box but can't afford to have one built right now and I always liked the sound quality from my sealed. I want to go for a ported box in the near future but want a well built one with low port noise and tuned. Does anyone have su…

Hey guys New to the Forum so dont hate if this is in the Wrong section . Alright to the point Im doin an install this comming spring The front stage is Focal Utopia Tweeters/Mid/Mid bass (1inch,3" and 6.5") No Rear stage. This is being installed in a 1991 BMW 850i (This is a Daily Driver) The truck space i have doesnt allow for a 13" or 15"sub So im planning to go with 2 12 inch subs ( Sealed Enclosure? ) This is my first install so i do not have a prefference yet to if i want a lot of bass or a little nor do i have much listening experience to other setups/speakers. What im looking for from my subs is bass that i can feel in my chest and to have clarity i dont n…

Alright peeps its almost rebuild time in the work truck. If you dont know, im running 4 sa8s on a saz3k @1 ohm in 2.2 cubes @35 hz. it sound pretty loud but im just not satisfied. I want it louder. I have about 2.5 cubes to use but im limited to the 4 8s or 2 10s because of height restrictions. any suggestions?? Im thinking maybe 2 Nightshade v2 10s on a saz3k or maybe even 6k if needed as i have a few saz3ks stashed away. Dose anyone make a louder 10 that would work in my space? im pretty sure i have the loudest 8s out there. any thought?

Keep us posted on this thing

I ran across this video today, and it made me wonder if this guy was talking out of his ass or not. What he's saying does make sense to me, talking about a square has more surface area to push more air out then a round woofer would. But if that was the case, then how come almost no manufacturer on this site even offers a square in any of their lineups? This part didn't make sense to me, because from what this guy is saying, everybody would be designing square woofers right?

I dont know if yall have seen this at CAF but it is just nuts. http://fresnoracing.ipbhost.com/index.php?...topic=508&st=25 Turns out this guy spent like 25 grand and he got it done right by some pros who knew what was goin on. Heres what he has: Vehicle: 2002 Chevy Silverado Regular Cab (1) Clarion VRX935VD (1) Planet Audio PLD6 6-ch 8V Line Driver (8) Planet Audio BB1250.1 (Subs) (8) Resonant Engineering XXX 12" Woofers (2) Phoenix Gold T300.2 (Mids) (1) Focal Polyglass 6.5" Component Sets (doors) (1) Focal Polyglass 5.25" Component Sets (kicks) (1) Focal Polyglass 4" Component Sets (b-pillar) (2) Stinger 5 Farad Hybrid Capacitor (Rear Amp Rack) (2) Stinger 1 Far…

i want to build a box but i cant find MDF wood any were so i was wondering if useing ply wood would make a big difference

I have my front stage running active with my 9886, h100, and mrp-f250. I currently have Focal 165a1 speakers installed. 6.5" in the stock location in the bottom of the doors, and the tweeters in the dash reflecting off the windshield. I'm not happy with the sound currently. I'd like to find some mids with better midbass, less harsh tweeters, and put my tweeters on axis. I'm new to the world of buying seperate speakers. I looked on madisound and found the Vifa BC25TG15-04 and the Scanspeak Discovery 18W/4434G-00. What do you think of this combo? I'd leave the mids in the doors in the stock location, and make a pillar pods for the tweeters on axis with the driver's seat. I…

its double layered MDF, final design is a massive thanks in part the Orion master of disaster Shane Christensen aka HCCAfan 3.0 cubes 33hz (the fun hertz) these are the initial first day pictures after some extensive glueing, I will be doing the final assembly tomorrow

Ok the xxx is loud and SQ right and the SX is the so ccalled budget spl sub, the SX is louder than the xxx then what is the point of buying the xxx when the SX is cheaper??? just thought i'd ask what is the Root mean square of the SX anyway..
