Impious

So.....why don't you just build the enclosure Aaron posted, and when you install it sit the enclosure on it's backside so the sub faces up rather than towards the back.... ?? The enclosure fits all of your dimensions.

Damn, your pictures of the CF's are a hell of a lot better than mine were....LOL

IMO the L7 is a good all around driver. They can get very loud in a properly designed and constructed enclosure, but are also capable of maintaining adequate sound quality. You already have it, and going that route is the cheapest option. Might as well stick with it. The Dcon is a great budget oriented driver, but I really don't think it can do anything that the L7 can't. You won't be missing out on anything by going with the L7 over the Dcon. Unless you just feel like trying something new......in which case, the Dcon is a good choice for a ported enclosure.

They have a really low inductance.....might work out well as midbass

Maybe you're dead, and see alive people.

Moving fast so far. Can't wait to see the results!

You can not test how low you can hear by yourself with a subwoofer. There are far too many variables which are going to invalidate any results. For starters, when you play a 13hz tone, your subwoofer isn't only playing a 13hz tone. It's also going to be reproducing tones at 26hz, 39hz, etc, which are known as harmonic distortion, and are within the audible spectrum of sound. Many people hear the 2nd and 3rd order harmonic distortions being produced (which for a subwoofer producing a 13hz tone at any reasonable output level, the harmonic distortion level is going to be extremely high) and mistakenly think they are hearing the fundamental, when they are not. So just because you "heard" sound when you played a 13hz tone, it doesn't mean you actually heard 13hz. You may have been hearing 26hz, 39hz, etc, and mistakenly thought you heard the fundamental 13hz tone. Then you also have issues with mechanic noises being generated from the driver, resonances from items within the room, etc, all of which are going to completely invalidate your test results. So the short story is no, you've done absolutely nothing to demonstrate you can hear down to 13hz.

I leaned a new word today, "Ohmage" lol I am the creator, seems pretty legit though........and has a good meaning Ohmage

If it helps, Bravox has a PAS Mag review hosted on their site: http://bravoxaudio.com/download/05.pdf

I'm not cool enough to be able to view the thread

You wouldn't need a 4ohm load, he was just posting the picture for example purposes. Most 2-channel amps are stable to atleast 2ohm stable per channel, and some are 1ohm stable per channel (which I believe the RF Power amplifiers are 1ohm stable per channel). As long as the final impedance is a load the amplifier is stable at, that's all that matters.

I'm assuming your question is specifically regarding active? The Zed Leviathan would be a very solid option for a 6-channel amp to run 3-way active. Most other 6-channels on the market offer pretty measly power output @ 4ohm per channel. The other option ofcourse is to just run more than one amplifier.

Bump for extended GB pricing!

You know what they say, the best form of flattery is imitation. If SSA wasn't such a leader, the others wouldn't be so eager to follow!

....for a Butterworth filter

I'm pretty sure the 800PRS offers a bandpass crossover.

Actually the Shiva-X really has nothing in common with the Adire Shiva other than the name. The Shiva-X is actually much more comparable to the Brahma series. The subs are excellent. I run a Shiva-X (original version, not the -X2) in my car and absolutely love it. High quality design and build, great sound quality, and more than sufficient output for my needs. Plus Kevin @ Exodus is a really helpful guy and great to do business with. As for power handling, why do you ask? Keep in mind they were not designed to be an SPL monster. I run mine IB so I'm not using a level of power anywhere near the driver's thermal limits. You really shouldn't need more than rated power to get the driver to do what it was designed and intended to do.

I don't know much about DC subwoofers specifically, but a coil change could potentially affect Qts and Fs which will change various aspects of the drivers performance and enclosure requirements.

What's the model # ?

It is really all relevant to the conversation. Yes, technically you would have a "3-way system", you are correct there. Where you get confused is that when most people are talking about the "-way" with regards to speakers, they aren't including the subwoofer. So if someone says they are running "2-ways" they have a tweeter and mid, and "3-ways" are a tweeter, midrange and midbass. If you consider their system as a whole, someone with 2-way front speakers would have a 3-way system, and a 3-way front stage would have a 4-way system. But you also have conversations regarding to crossovers/processors/headunits, in which case the "-way" needs to include the subwoofer. A 3-way headunit can highpass (for the tweeter), bandpass (for the mid) and lowpass (for the sub). A 4-way process has a highpass (for the tweeter), usually 2 bandpass channels (one of the midrange, one for the midbass) and lowpass (for the subwoofer). Crossovers/processors/headunits are also talked about in terms of channels. A 6-channel headunit has 6 individual outputs (front left, front right, rear left, rear right, sub left, sub right), however that headunit may or may not be a 3-way headunit. If the front and rear channels can only be highpassed, but not bandpass, it's not really a 3-way headunit. But if it can bandpass either the front or rear channels then it would be considered a 3-way headunit. An 8-channel processor may or may not also be a 4-way processor in the same way. Confused yet? Yes, there has been an 8-channel 4-way headunit; the Clarion DRZ9255. There are also 4-way processors; the JBL MS-8 and Alpine H701 for example. You can also use a 6-channel "2-way" headunit (front and rear channels can only be highpass) to create a "3-way system" by using the lowpass crossover on the amplifier in conjunction with the highpass in the headunit to create a bandpass on one of the channels. I think some people stopped including the subwoofer in the "-way" for the entire system with the advent of surround sound, where the subwoofer channel started being denoted as ".1" in the terminology (5.1, 7.1, etc). But yes, if you have a tweeter, mid and subwoofer you have a "3-way system", but a "2-way front stage".

Both Brad and I have 603CF's on the way. I cannot wait. They can't arrive soon enough

Yes, 7" mids only. And they don't sell complete "component sets", only the midbass (and I think they might offer outsourced tweeters, I really don't know off hand). But they do not offer any passive crossovers, so you would have to run active if you wanted to go that route. As for rear speakers.....my kids have no problem hearing the music in the back of my full size sedan without any rear speakers, even at moderate volume levels.

Something like this? As to your original question; I agree with the others. For your goals, a nice single or pair of 12's IB would be more than sufficient. Keep it simple. I run a single Shiva-X IB in my vehicle (not the Dcon pictured, that was just for the review) with what I would consider to be great results. And the baffle is painted black now so it looks a lot better Oh, and I can still fit anything I want in my trunk, which was also my goal. EDIT: I missed the part where you wanted to keep functionality of the folding rear seats. You could hang the subs from the rear deck firing towards the rear window, just won't have much bass with the seats down.
