Subwoofers / Speakers

Building a little setup for my dad, its going into a volkswagen jetta, already has an alpine mrd-500 in it, so im basing my sub decision around that power. He listens to oldies, classic rock, country...so i was thinking something along the lines of a pair of sundown e8's, sundown sa-10 etc....any other recommendations are welcome. Also thinking either a low tuned ported box, or 4th order bandpass. Hes missing a bit of hearing on the low end scale so this could make up for it.

At low volume my subs really hit hard but it seems as if the higher the volume the less of that deep bass i can hear/feel. My head unit goes to volume 62. At 40 i can really hear the deep notes. Should i tune subs for the lower volume and just not turn it up passed that?

Anyone be able to give me an idea of what this enclosure may be tuned to?? I have a picture and a sketch with the measurements I took. The bottom right drawing is the port. It is shaped like an L, and above that I was trying to show that it is 16" in height. Any help would be great. Just trying to get a rough idea of what this enclosure is all about. It a "Turbo Vent" enclosure, could not find anything on the internet about them.

Redoing port soon and need advice. Sub is a Fi Q18, 6 spoke basket, SPL audio recone, on under 1k. Port is 12" plastic pipe. I want it tuned at 29 and I can get there 2 ways. 1. 34" of pipe internal and 2" external giving me 8.08 cubes. And 2. 28" internal and 6" ext. giving me 8.48. How much would the extra .5 cube affect the sub. (Fi recommends up to 10 cubes for 1 Q18)

How much volume is occupied by the mj-18 driver? Are the recommended box volumes the internal volume of the box, or is it the internal volume minus the drivers volume? Thanks

I'm planing to purchase a lvl 5 15" in the very near future and so I'm working on the box design and I was hopeing someone could give me the volume of this woofer. Thanks...

How do these two subs compare to one another..?? I am currently running a18 Fi Q sealed. Box is on the rather small side with polyfil but i know this sub is capable of more.... Seen the vvx can be ran in small sealed boxes and know the play lowend pretty good.. Figured i may switch from 1 18 to 2 15 due the fact of more cone area.... Amp is a mmats dhcx2200.1

how do type r s compare to w3s

planning on running 2 of these. are they able to handle upwards of 1200-1400W?? i know they are rated at 500 rms each.

out of these 2---which do you like better?I will respond when i see someone elses opinion.

Just looking for an opinion here. I have not used either, but I have a rep that is trying to sell me a W7 for 400 and I've been looking at the XCON, but of course the rep is saying that the W7 is by far better than the XCON. He's stated that he has been a JL rep for the last 7 years and he has yet to hear a sub sound as clean and heart pounding as the W7. With no preference towards spl or sq, what do you guys think the better buy would be, or just give me something for arguments sake. He says that the W7 is a better built product and the research invested into the W7 makes it the better choice. I know some of what he says is true, and I'm getting dealer cost here for the …

http://www.madisound.com/catalog/product_i...products_id=313 looks really nice and cheap.

what is this i heard about the magnums being out of stock for a while. and know one seems to have a specific date. can anyone clarify? al

Im waiting on that 20" you proposed a while back...any updates?

hello everyone i want to build a wall with 4 15s at 500 rms or 2 18s at 1000 rms i have a brutus 2000 watt i want some deep bass i have looked at the dcon 15s, hdc2.5 15s, the icon 18s, havoc 18s,if anyone has any expierence with these subs or have any others in mind throw your opinions in here

Sup guys, i'm really interested in the mags, i know it's goin to cost me some money but def. well worth it, i'm thinking of putting up a wall in my car and go with either 3 12" mags or 4 12" mags, most likey each powered by a nine.1 or an RE 12.1, i was wondering how much space would be recommended for them i'm goin to say probably 2.0 cf per sub? and what would be a good tunning for it, probably around 32-35 hz? its either a wall or 2 12" in a crx style box with a orion 2500d.. suggestions are welcome. thanx

I got a question for you guys that have heard walled subs. I got two IA DP 21s now in my truck where my back seat was facing up ports up. Sounds real good except my poor back wall flexing. I never seen a walled vehicle in person is that the way to go? If they sound good I'd be down to do it over?

110 volts to each coil The surround was probably 150 degrees when I first cut it open! I let it sit for a couple hours and it was still to hot to pull it out of the wooden cradle http://youtu.be/XglfJ10tryA

Finally got some time to do my Wifes build for Bass Race. Equipment is 4 MJ 18s and a Massive Audio P3000.1. 18.5 cubes tuned to 30 hz. On to the pics any comments or critisim is always welcome. what Im working with. the old boxes the wood some scraps some together the port just needs the top in the van should have made it taller. This will be walled off behind the second row of seats. Bracing will be in the form of threaded rod. The only reason its in the van now is cause I dont have any room in the garage for it.

1st of all, im new to the forum.. so hi everyone Had a demo of a 12" Mag two years back, in canada - the car was ratting at an SPL probably similar to the subs' output, so it wasn't exactly an ideal install and demo... however, i got interested, enough now to spring for one. but i live in switzerland. how do I get one? pls help... me wants MAG bad!! I could offer my car as a demo-car.. :D cheers, Mike "Demo car": it has 2x10" midbass drivers in the doors, Exact MG10 fullrange upper end, (hopefully soon Audax Midrange and Ribbon tweets), an Alto UCS Pro processor, an embedded PC and homebrew USB-DAC for a source... currently all parts are a percentage short of being ins…

I am thinking about re-doing my setup and would like some opinions. I am thinking about moving my 4 DP21"s to the passenger side, and port on drivers side. Then the idea for 8 15"s started creeping into my head. The subs in each setup will be on 2k wrms each, so it's not really a fair comparison since it will be twice the power with the 15"s, but o well. The 8 15"s would be on bottom with the port across the top most likely. Some of the subs I have been considering for the 15"s are: BTL's, new DP's, Lvl 5's, and Exos. Right now I am leaning towards the Atmos Exos. Wall is in an 03 Expedition at the B-pillars, 40 cubes and will be tuned somewhere between 28 and 32hz. Prob…

I have a 2002 nissan altima without the bose speaker system. I currently have a Pioneer deh-4200ub headunit and in the front I put in 2 alpine type S coaxial speakers. In the rear deck are 2 pioneer 6x9s that were installed by the previous owner. Im looking to add some more midbass to my system because the current speakers just seem sort of flat. I dont have an amp hooked up and the HU is powering the speakers. Ive read here that an amp is necessary to get the most out of your speakers because the HU pushes something like 22w. Im pretty content with the type S's up front sq wise. They are 5 1/4 if I remember right and thats all that would fit in there without fabrication …

The only place i see you can order maw-12's is directly from mach 5 audio, which is based in canada, so wouldn't shipping be really high? is there any store in the US that carries them? (i wish ssa carried more than just the 15 and 18) thanks for the help

Hello all my daily ride is a mercedes clk 230 Kompressor and my setup is two jl audio 12w6v2 sealed off a jl audio 1000/1.... very good SQ and output level not bad but............. i want morrrrrrrrrrreeeeeee So i'm interrested by Fi audio ! i can make a box of 3.5 cu ft maximum (volume net) a Fi Bl15 ported in a 3 cu ft tune to 32-34hz seem to be a good thing!! the 15" will be powered by my 1000/1 (1100-1200wrms) i think upgrade my amp soon and take a 2000wrms good choice?

Hey guys, we recently purchased '11 Toyota Venza with stock stereo and I'm pretty dissapointed with the audio system in a $40k car, whether the stock or the upgraded JBL package system, real disapointment. I want to upgrade the stock speakers only, as this is mainly my fiance's car to work and our family car for trips. I already did my Scion last year with Sundown amps, ID speakers, knukonceptz, secondskin, I went from simple upgrade to $3k built So one car is enough or I'm gonna get serious beating from my lady Anyway I'm looking to upgrade the stock speakers, we listen to everything from techno to rock, I like warm sounds, no harsh sounding speakers, something laid back…
