Alright so I'm planning on starting my renovation of my "system" and I'm planning on using this woofer: https://www.acoustic-visions.com/~acoustic/products/subwoofer_drivers/CSS_SD12/ in a TL box. Powered (hopefully) by an Alpine MRD-M1005. Opinions?

That's why it's the leading contender for my bass driver, I like quality, and I like cheap, but I love both at the same time.. Also, I intend on replacing my mids/highs with these: https://www.acoustic-visions.com/~acoustic/products/subwoofer_drivers/exodus_fr125/ Apparently it's basically Adire Audio, since they closed shop, Creative Sound is using their motor. -------------

not really using their motor...just the XBL^2 technology

Well, really, that's like saying a Ze-Donk is different from a Zonkey. And CSS and Adire worked on it together before Adire called it quits. -------------

The Fr125 was designed by Dan Wiggins, CEO of Adire Audio for Bob Reimer of Creative Sound Solutions. Adire Audio did a lot of OEM design work along with their own offerings. That subwoofer is an excellent choice. I'm very sure you will be happy with it.

The Fr125 has unheard of on-axis response. However the higher frequencies drop off quickly off-axis, which is how you would be doing most of your listening in a vehicle. You would need to add a tweeter and a proper crossover to get adequate results. Also even though it has quite a bit of excursion, it is still a 4" driver and not designed for infinite baffle solutions. So you would probably have to build an enclosure to get decent low frequency extension. They are great speakers though. I'm using a pair of them as surround speakers in my home theater, as well as a pair of their cousins the Wr125 in my tower speakers.

Also, kep in mind that the mid you have picked out is a 8 ohm driver. You'll have to buy an amp rated at TWICE the 4 ohm rating that the driver is rated for... i.e. if you WANTED to design the system for 100 watts to the mid (at 4 ohms), you'll have to design now for 200 watts (at 4 ohms).
That makes certain you have enough power, otherwise you COULD conceiveably run the amp out of power without even realizing you are doing so. Remember the amp will make only one half it's 4 ohm nameplate rating.
Also, at 86dB sensitivity, you WON'T want to skimp anywhere on power. Not saying to dramatically OVERpower it, but certainly make certain you have the RMS rating available for it.
Oh, yeah, and add a tweeter, too!  ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

The plan is to fiberglass over expanding foam.. You think that would suffice, orrr no? haemphyst wrote:

Well, I figured as much, what with an Re of 7 ohms.

Also, does anyone know where you can get Mpyre Midwoofers? I was hoping to use them in my rear deck but apparently they don't distribute in the US anymore.

I believe they are no more. The closest thing available right now that I know of is the CSS SDX-7. I've used the FR125 and I agree with haem, you'll probably want a tweeter, especially in a car. ------------- Support the12volt.com

Read my comment above to see why.
Also, I may be willing to sell my pair of Mpyre mids. They are still brand new in the box.

Okay, so is this what you're trying to say: because I'd be listening off-axis, I'll lose the highs? If that's the case I'm thinking I might as well just hold on to my Alpine tweeters. Let's make a deal! -------------

A frequency response of 65Hz to 20kHz ON AXIS. Steven addressed this in an earier post to the thread...

Okay, so I think I got it... Haem, can you still design that TL box for me? Hopefully I'll have everything ordered by Friday. Worked almost 100 hours last week, so, plenty of funds.

Sure... shouldn't be any issue. I'll give ya the numbers, but I'm not really good at "drawrin'", so I'll leave that to you!
I'll just need maximum outside dimensions.

Bueno, 14.75"(h)x36"(w) and depth isn't an issue, but I'd like to keep it under 2 feet (I'd like some trunk space)

::UPDATE:: So I've decided to ditch the Mpyre mids and go with these: https://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-826 Much cheaper, and they take up less space. -------------

I wouldn't use the shielded version in a car as it will be much larger and harder to install. They make a 5-1/4" non-shielded as well. Also, that speaker is not really suitable as a mid: what's your intended frequency range? ------------- Support the12volt.com

I tried this once and the fiberglass resin dissolved the foam. You'll need a different solution. ------------- "I'm finished!" - Daniel Plainview

100-400hz... You think these: https://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-850 would be better suited? And what do you think my crossover points should be? sedate wrote:

I can't remember what install I was looking at, but as I'm thinking I'm pretty sure it was Haem's car, where what the installer did was cover the foam in aluminum foil, and fiberglassed over the foil. Which apparently knocked out any chance of the resin dissolving the foam. Gah, maybe I'm in over my head on this one.. -------------

Well, that might sound better than the subwoofer version, although it has a really low power rating. Are you looking for a cheap way to experiment? Try THESE. Do you have to use a 5-1/4" frame size? If not and if you want an outstanding woofer that really sounds good and will last a long time, THESE are a good choice. or, like I mentioned earlier, the CSS SDX-7. ------------- Support the12volt.com

Well, the stock door speaker is 6.5", but I've gotten pretty alright at fabrication in the last few months, so size wasn't an issue for me. I'm pretty much just lookin for the best gear for lowest amount of money, but isn't that always the quest?

If it helps the Mpyre speakers are still a bargain at $100 each. You won't find a lower distortion midwoofer. It's basically a 4 ohm version of the SDX-7 David mentioned above.
