What I got now is very musical (even at high volume)and I love it as a daily setup. I just crunched #'s on the torres box calc and I'm gonna go with 3.5^3 tuned to 41.5hz w/ 80 inch of port. Results on Saturday!

I've had other configurations w/ my BL 15 $ JL 1000/1 but not this set up no. I figure walled at the trunk would be best for comps. I know, I've had tons of people saying I should be close to 150 Yeah, just HO alt. No $ for batteries yet. Don't know the exact peak of the vehicle.

I'm not "pissed" but I am a LITTLE let down. I was hoping 145.0 with the gear I have now. Maybe this box and two solid batts will help

Oh yeah, it's a 6" inch aeroport. I wanted to try something different. The thing is it sounds REALLY musical. I can't do two 6" ports, I don't have the space. I have a comp on Saturday and plan on doing a SPL box. I'm thinking 3.65^3 @ 40hz w/ 72 inch of port? Should I tune lower? Also did my first two beassrace runs in my life (practice) and got perfect 129.9 on the second run w/ Bone - See You At the Crossroads!

I'm looking into buying a 15" BTL fully loaded. My question is, can I tune my box lower than the recommended fs frequency? If I did, would it affect the sub in a bad way? Poor sound quality? Just wondering if there would be a negative effect on the sub. I think the fs frequency on the 15" BTL is 37.9. I like low frequency hip hop and want to tune my box low like 30 hz (at the lowest 25 hz). Is this not a good idea, what would be the result?

Is the DMM method a fairly accurate way to measure the watts output of an amplifier? I set the meter on AC volts, connect leads to speaker terminals (w/ subwoofer still hooked up), play a sinewave burp and take that reading to determine how many watts went to the sub. Does that sound correct? I already set the gains w/ an o-scope so I'm not trying to do that. I want to calculate how many watts actually is going to my sub thanks

Hypothetically speaking If my sub is 1.5 at each coil, I wire down to .75 ohm. Now with the sub hooked up I burp 50 hz. I get a DMM reading of 40 volts AC. My voltmeter showed 14.2 for the duration of the burp. Say the imedance went up to 1.3 ohm, what would the equation be? Do I need to get a fancy clamp meter or something?

I have a 15" AA SMD that's powered by a Stetsom 7k2e. I will gain down to 3500 - 4000 watts @ 1 ohm. Biggest enclosure I can fit in the trunk is 4.5 - 4.6^3 before displacement. The sub will take up .24 cubes and bracing .2 That leaves me w ~ 4.05^3 before port. I'll be using a 6" PSP Aeroport. A few questions I have are 1. Do you find port area in the straight length pipe, or at the very end (diameter of the mouth opening)? 2. My PSP has a 6" diameter straight pipe that flares out to 8" at the very end (on both sides). Which number do I use to find port area? 3. Do PSP's really require half the recommended port area as a slot or straight round port? If this is any help, these are some specs on the sub Recommended box size: 2-4^3 Xmax: 32mm one way Effective cone area: 810 cm

op questions 1 ? 2 ? 3 ?

Bump for more answers to my op questions

Thanks for the help So.......... My 6" aero opens up to 8" at the very end on both sides. That gives me a port area of 50.xx^2 Now I read somewhere that PSP Ports require less port area (not port displacement) than slot ports. Some say close to 50% less port area. That would mean I am close to your recommended 90 - 110 square in?

Cool, thanks! Back to my questions. 1. ? 2. ?

Right, my bad. ~32 - 33 hz

Ok, say I were to do a slot port, how much port area would I need for this application?

I'm pretty sure DC Power makes that

Most of the time people are like "give as much info as you can". Man, that was a lot of info!

Equalizer, right?

90 grand up front and we'll start talking $90,000!!!!! Is that per sub!?!?

09 Toyota Yaris Sedan FTW Big 3 I paid $16,000 brand new! 40 mgp easy!!!

After all specs and pricing is weighed, what would be the better route? Amp would be a stetsom 4k2d or saz 3500d. Biggest enclosure I could do is 4.2 cubes before displacements. I will use two 4" x 17" aeroports (double flare). Thanks

Thanks 4 the replys fellas. Specs for the SMD say anywhere from 2-4 cubes will work. I figure w/ enough power, I should be alright in a 3.5 cube enclosure (after displacements)?

wouldn't happen to know the DC lvl5 recommended specs for ported enclosure? Anyone know the displacements of the two different subs?

Yeah, I plan on getting in the lanes from time to time. This would be my daily though. If I can't afford the SMD because I still have wire, terminals, batteries, MDF, etc. that I need to buy, what would be next in line?

Does anyone have any reviews or info? Im thinking of trading my JL 1000/1 for a 1400d.

S**t man, I almost did it. Thanks form talking some sense into me!
