Subwoofers / Speakers

I need clarification on something. I am doing a weird wiring scheme for some tweeters, well I think I might. I have 10 tweeters that have a nominal impedance of 6 ohms. I need confirmation on the load if wired in this fashion. 3-2-2-3 By my calculation this would give me a final load of 3.75, correct? Each set is wired in series, then all 4 sets are wired in paralell.

I own a jbl bpx500.1 monoblock 1/2 channel amp. the amp can run bridged x1 780w at 4ohm, parallel x1 760w at 1 ohm, and 237w x2 at 4ohm. I have a dual 4ohm voice coil speaker that can provide 2 or 8ohm loads. can my amp support 2ohm x one channel?!?!?!?!?!? i cannot figure it out!

At this juncture, I don't have a particular subwoofer in mind. I would just like to inquire whether I can build a ported enclosure larger than recommended to obtain a lower tuning. If so, what level of increase could potentially harm the driver? Thank you.

Hi, people! I've been sending some e-mails to SI lately, but have been getting zero response because I get a delivery failure notification. If somebody can tell me how to reach these guys, I'd be very thankful. The subject is getting a SI Magnum D2 15" sent to me in Norway, and possibly getting myself a dealer status if it's possible. Norway needs some better equipment than Pyle/Boss/Sony/MTX etc... By the way - just out of curiousity - which is better: The Stereo Integrity D2 15", or the SoundSplinter RL-p 15". The RL-p's cost less than half, but seems quite good after what I've heard. Is the SPL and SQ comparable between these two, and what about the durability? In my …

I came up with this the other day and posted it on SMD, I figured I should post it here too. Hopefully someone will find it useful. I'm sure most people here have come across the "12-16 sq in of port area per cube" guideline for slot ports and the "9-12 sq in per cube" for aeros. The problem with both of these is they only consider box volume. Both input power and tuning frequency, along with box volume, have a great effect on how much port area you need. This is why I've been recommending to people to NOT use those rules of thumb. Online you can find several websites (such as carstereo.com) that have port area calculators using the formulas developed by Dickaso…

Should I go with 3 or 4 kicker 12L7's.....2 13w7's....or 2 or 3 12w7's I'll probably haev either two kicker 1500 watt amps or the kicker 2500 watt amps. I'm looking to bump hard around town, sound nice and get real loud. It'd be nice to about hit 150dB if possible. thanks! Or if there are any other subs that are comparable if not better, suggestions are welcome!

ok this is my situation i currently have a 2012 Mercedes C350 and just purchased audison fronts and audison rears , audison bit one , and a hertz hx300d 12" sub 600 watt rms 1200 peak all powered by a audison voce 5.1k 5 channel amp that has 1000 watt rms at 2 ohms for subwoofer. So i had it installed at the shop and the box was a ported custom built box with the ports on top and the sub firing towards the trunk and had the amp rack installed behind the folded down back seat. I got it back and the bass just wasnt entering the cabin at all and the rear speakers arent in the deck but in the back doors and after alot of reaserch i found that everyone says mercedes trunks e…

http://www.diyaudio.com/forums/attachment....tamp=1150912134 will be buying a 20' section of 6" PVC soon and will be making 6" port ends on a mold from fiberglass.

my first post... i never heard of the magnum before and for only 350.00 why not try it out... and if i dont like it.. sell it... no problem there... i like to explore new things that many people dont anyways especially car audio.. when someone says "whats that" "how many subs you got in there" that right there is worth every buck i put into it... but to the question... i'm pretty set on the magnum 15 so whenever the next batch comes in... please let me know... 1. i really like the memphis amp because of electrical issues but i can't decide on which one?? the 16-mc1000d or the 16-st1000d??? anybody know if there's any difference??? 2. will 1000 watts be able to really g…

I'm looking to pick up some new subs for my truck. Looking to keep it stealthily looking. So ether behind or under the rear seat of the truck. I have a crew cab Chevy. I'm looking at Alpine 10" swr-t10 Jbl ms-10sd2 Sundown Sa-10 d2 Sundown SD-2 10 D4 Sundown SA 8 v.2 D2

I have the 8 speaker Boston Audio "premium" system in my 300C and have recently upgraded the (3) 3.5" speakers in the dash to Infinity Kappas. A very bright sounding speaker. I am looking to replace the 6X9's in the rear deck and front doors, but in order to get the most out of the factory Boston amp, I would like to find 2-ohm speakers similar to the infinity dash speakers that I have already replaced. However the Inifinity 6X9's take quite a bit of power (and will not be adding another amp), are there other brands that make 2-ohm coaxials??

Hi guys, I am considering doing an upgrade on my factory speakers. I have a Toyota Yaris Hatchback with a current setup of stock head unit, stock speakers, and a pioneer bass tube (The Pump TS-WX20LPA). I am not into SPL, rather a solid SQ which at least I can impress my friends with and which I can enjoy listening of course. I live in a small country and the choice of brands is rather limited and few shops let you listen to the speakers before actual installation. So I'm counting on you guys to help me in making a good choice Right now on top of my list are the Focal Access 165A or the Kicker KS. I also went to a shop which supplies Hertz (I heard they also make good c…

i know everyone favors ported boxes but what will be the best choice four sealed 15's or four ported 12's? im not competing just for daily pounding?

Hey all, My FI SSD 15 finally bit the dust with a fried voice coil. I tried to contact FI about possible warranty, but had no luck So here I am trying to decide on a new sub. My current amp is a Sundown SAE-1200d. I have heard that they are actually under rated, and push more like 1300-1500. With that being said, what are some recommendations you all would have subwoofer wise? I am looking for a 15'' btw I was thinking about a DC Audio level 3, but it seems like they only come in dual 4 ohm. Any help with this, is greatly appreciated ~Tyler

I have just received news that Stereo Integrity was broken into earlier this afternoon.....speakers as well as business documents are currently missing...ALL OF THEM...as well as other personal equipment deemed as CRITICAL listening elements to Nick Lemons...a report has been filed and SI is looking into insurance support... I am very upset, disappointed, and mostly saddened that such a great company and person has had his heart and hard work stripped from him.... In case said physical items are not recovered...I will consider starting a gift fund for SI...I believe in Nick...and I will help him in any way I can.... In fact....if the items are not found...I will donate my…

was looking at Sundown Audio SA-6.5CS and Skar Audio VXI65 6.5 because there on the site. what do u recommend? what other brands and models to you recommend? i havent looked at amps yet but if you can match up some stuff. this will be going with 2 12 icons on a sundown 1200. front and rear speakers are all 6.5.

So I'm coming from a Q, it's in about 2 cubes and tuned to 30hz. I'm powering it with an MD2 being a bit conservative on the gain. The output is pretty good for a twelve in a trunk car and the lows are thunderous, but I want something that will also play the upper frequencies 45-60 a bit louder than the Q does. Lookin for something with the same punchiness of the Q also. Probably looking at 2 12's sealed, I think I'll be satisfied with the output there and I can turn it down if needed. Only subs I've considered were the SE and the SSD w/ a copper coil, possibly the TC-9 too. Any help/suggestions are welcome, I'm open to anything.

Hi guys, A tinsel lead broke on one of my mid last week. It's impossible to solder properly, to fix that. So I'm looking for a replacement. My budget is not high enough to just buy a new set like the Focal KR2 or KRX2. I was thinking about a set of JBL gti 608 but I can't find one. I will buy a mini-dsp as soon as the funds are ok, maybe for Xmas. Until then, I will use the passive filters for the Focal tweeters, and I want a set of mids (not to be used on the passive filters). Crossover at 80 or 100 Hz on my Pioneer head unit. I saw a lot of people talking about ScanSpeak speakers, like the Illuminator or the Revelators. Can that be a good choice ? I'll change …

Right there ... oh yeah. Will be running ~ 1000 watts. I'll make the enclosure fairly large - can always take away airspace if need be. It'll be sealed this time around (no way I'm going to try and figure out a port), question remains ... how big ? - Steve

this just in, just found out today when i got some new h2's in, they changed the surround to a foam style surround that is taller. I was like wtf, whats this all about, and emailed my buddies at tech support to find out. my questions: whats the deal with the new surround on the h2's? any advantages? Reason for design change? They seem to look like they will allow more excursion, but thats all from looks. shane his reply: More power handling, and greater excursion, 32mm now ohhhh, cant wait to test!!! got someone testing at sbn, hehehe. will have pics soon.

Hi all, This is my first on the forum so please bear with me. I just installed a bass tube in my hatchback Toyota Yaris, the Pioneer ts-wx20lpa http://www.pioneer.eu/eur/products/archive/TS-WX20LPA/index.html. The sub is hooked with the factory oem h/u, therefore I installed a high/low converter, the exact model being this one XScorpion LC09 http://www.sonicelectronix.com/item_40150_Xscorpion-LC09.html . The power cable is a standard cable which came with the sub and is directly connected with the car battery (no capacitor or fuse). The sound is quite good and solid considering it is a bass tube, however I notice that at certain very low frequencies the bass response suff…

Im looking for two 10" Incriminator Audio 187's. If anyone has any leads to them please let me know. As we all know the Lethal Injection series took them over so they are not made anymore. Thanks

How does the Fi BL compare with the IA Death Penalty and Death Row in output, sound quality, and overall?

I've tried looking on their website, but it only says "N/A". Would anyone know the Specs? to build a custom 33hz box? My local car audio shop needs to know the specs before they build the box.
