Subwoofers / Speakers

I have an IA 20.1 on order and am thinking of going with two Mag D2 15s for it. I designed a box that is 7 @ 30hz w/ 90in^2 vent area. I was wondering if you guys had tried that type box yet and just how does it do? Does it start to dip after 50hz? I am sure it wil probably ring my bell from 30 - 50hz. I am just worried it won't do much afterwards. About where would you said my 3dB down point would be? Also, I have a goal of a 146+ new TL with this setup Legal on music. 98 explorer....think that is too lofty of a goal?? Thanks :-D -Alex

soooo i wanted to play around with differnt designs in bass box pro, but there is no stereo integrity on the list? is there a place where i can get the full T/S pramateres for the mags?

Please read and abide by the rules. Thank You.

what is the cutout diamater for the sub, and what would be the cutout diamater for the 2nd baffle if i wanted to have the flush mount going on. i was originally gonna do 3.5 cubes ported, but i would need to do a build in for that, and with no heat in the garage, i am not gonna do it till sping. so i ended up going chosing to go 2.5 cubes sealed.

my friend is building a box for me that will be 3.7 cf @ 27hz.My question is how much port do we need? what's the displacement for the port in that box? any help is appreciated

Hello everyone. It`s Marcos from the U.K. The only person in Europe (as far as I know) who is using the new 15" Magnums. I hope you guys can see these photos. Last time I was on here I had difficulty in doing it. Anyway. Here goes. Starting out: It looks like a house. The baffle is in. And look what`s going in it. 4x 15" Magnums 3x 6" Aeroports. The box is 20 cu.ft. Tuning it to 27Hz. Is this O.K.? Please tell me you can see the photos?

ok. i built my boxes (still unsure about the subs), and the port came out looking funny. I'm almost sure, but just to be extra sure, i figured someone could help me out. when i ported my boxes, i took the cubic inches of a different boxe's port (3 cubes at 34 htz) and used the same on my 3 cube box (also at 34 htz) the difference is that it isnt as deep, but longer... even though the dimensions are different, because they both have the same cubic inches of port, it's still tuned to the same freq, correct? thanks

where can I purchase this and how much will it be shipped to 91803. Im interested in purchasing 2 if its not ok to put out prices please pm me. Thanks

So once I get everything else EVER done to the car I would like to get some mags. I hear too many good things. I'd like to stick with 15s but they're so big, and my trunk is not. My question is how much air do they need behind them in a vented enclosure? I'm not sure how much i can squeeze out but it would probably be 4-5 cubes if i really try. I'd like to stick at that for a pair of 15s. Obviously thats right where i should be for 12s but...aren't 15s so much prettier . So will there be a huge decrease in my low end or output? Would it be enough to justify just using 12s? Whats the minimum volume ported you would use for two 15s?

Merry Christmas everyone!! Here`s a card for you all. And have a BASSey NEW YEAR!! BTW: The fluffy puppet thing is known in the U.K. as FLAT ERIC. It was used in a LEVIS jeans advert years ago, bobbing its head to a mad Bassline whilst sitting in a car with its arm resting out the window.

were there ever production d4 magnums made? if not, is it possible to special order some? i dont understand why they're all d2, thats great for one but what about pairs? i dont want to run my crossfire as .5 ohm daily, or at 4 ohms. are there other wiring configurations im not aware of to get 1 or 2 ohms out of 2 d2 drivers?

I'll skip to how this box sounds since that is probably what most of you are wondering about. To initially demo the sub (kove armaggedon Z) I put it in a sealed 1.3 cubic foot box just to get a bearing on how it sounds. I'm using a nice dvd player, horrible receiver (I have no idea where the xover is set but it sounds high like 150) and a Tapco J2500 pro amp 2500wrms at 4ohm. I ran through my normal sound quality music at low levels to both break in the subs and just zero my ears to quite volumes. While playing Claude Chaloub's self title cd I noticed the sub seamed to peak in the 50's and 60's (which yes could be that sealed box) it also seamed to sound a bit dry in term…

How do these compare SQ and SPL wise?? I'm waiting to hear from a guy about a used RL-i 12" but also there's a local Treo dealer who said he'd sell me a TSX 12"D2 for $150 new w/3 yr warranty. It seems the 2 are fairly close in rms power, the SS being from 300-500 rms (I think) and the Treo being around 400rms (claimed it's underrated)... I imagine that both have more than adequate sound quality, but what about output? Any experience w/the Treo line? The dealer mentioned how the Treo is a 'unique design that makes it louder than it should be', take that for what you will. I'm limited on power (~300-400w rms) so I just want to make the most of what I buy and have some…

[email protected] I want to know if i should but rl-p12 or rl-p15 or the alpine type x. I am looking for more spl the sq (about 60 40). I am going to buy two of them. Thank you for your help!

hi i have the new mag and wanted to know if 2cf tuned to 30hz sounds good for a single 12 or what would be more efficient?

ive been looking around, and i cant find hardly any info on the re subs... can anyone toss me a link. also on where to buy them

hey guys i'll be ordering my 15 mag shortly and was just wondering how this sub will cmpare to my old 16ov2 and e15a.I am looking for a good sounding sub that will get loud and easily handle my crossfire vr1000d(1000 rms at 12.5 volts).Any help is appreciated.

in a truck, i used to run 3 memphis pr 12's in a ported box around 40 htz. the subs were awesome, i loved them, but since i can't put all 3 in my new car's truck, i'm looking for a new pair of subs that will give the memphis' a run for their money. i've done some reading on the diamond audio d3's and liked what i've heard so far. a few people said they slammed, but mostly i've heard a lot of compliments on their sq. well it's all good w/ the sq and all, but i'm looking for something that'll straight up S L A M !! will these do the trick in a box ported around 35 htz? and if you have any suggestoins that's cool too... i'm buying off of e bay, so i'd like to keep it around…

I know I know... This is the 2nd time i've asked this question, but noone seems to read old forums so I figured i'd ask again and see if anyone can help me out.... So has Anyone ever heard the Diamond Audio D3 12's? i'm switching from 3 memphis power reference 12's in a ported box (40 htz) in an extended cab truck to 2 D3 12's in a ported box (34) in a trunk of a grand prix... can anyone give me a heads up as to the loudness difference btw the 2? i'm hoping to get at least just as much sound out of the d3's as the pr's...

Hello all, ive been shopping around the last month for my next seasons' sub purchase, and "someone" who's close to SI and Team Smoke suggested I dabble with the Stereo Integ Magniums as a SPL sub in my Corvette SPL car build. Being that it is, an SPL only vehicle would it be honest to consider the SI Mag's to be a SPL or a SQ related subsoofer? I know there are alot of more variables to contend with beyond just the sub that dictates a SQ or SPL useage, but im suggesting my application will only be SPL, for highest numbers and not necessiarily the best SQ, since we all know there is a trade off at some point on something, ya know...the iron law thing Before I posted th…

Well during our testing tonight we had ... a development. We tested two prototypes tonight and when we took the second prototype out the motor fell off. The prototype that survived was our mid-line prototype that we got in a few days ago. And in case I haven't posted about it, we are coming out with a mid-line speaker. They'll be available in 10's and 12's. So yeah, here's some pics. The first two pics are of the busted driver and the third pic is of our new mid-line 12.

I never got aroudn to showing anyone these yet b/c I've been crazy busy with work ect. Anyway here's a lil eye candy for everyone I'll be making a few vids soon along with a formal review for the Magnum's. And for anyone who doesnt know my box is roughly 11 cubes total 3.5 per sub tuned to 28hz . Amp is at 2ohm until a new Alt gets into the truck. Here's a pic of my box before install for a frontal view of the subs. Lets just say this thing is quite the beast

Well I know MB Quart was bought by Rockford Fosgate a few years ago and the quality of their speakers went down. Now MB Quart is owned by Maxxsonics...the makers of HiFonics, Crunch, and Autotek. Are the new line of MB Quart speakers any good? I have a set of MB Quart speakers made the year before they were bought by RF and I love them....but will their new speakers be as good? I'm looking at the Premium line specifically.

has anyone heard of titan subwoofers..BESIDES the home audio titan subs..

for a decent price of 165.... how much are these worth? i know they are pretty rare, but is it worth the 165?
