Best sub ~$200 for sq

[brn2ply7]

Needs to still have good punch to it but i am looking for crisp sq here guys. So throw out some options.
Running 300rms at 4ohm of a 300.2 art series.
Thinking about this memphis:

I'm selling a nice Infinity Kappa 10.1D for $95 shipped if you're interested.

Specs:

Size 10 -inch
Impedance 4 ohms
Cone Material Aluminum
Surround Material Butyl rubber
Sealed Box Volume (cubic feet) 0.6
Ported Box Volume (cubic feet) 1
Port diameter (inches) 3
Port length (inches) 10.4
Free-Air Yes
Dual Voice Coil Yes
Sensitivity 94 dB at 2.83 volts
Frequency Response 18 - 200 Hz
RMS Power Range (Watts) 75-350
Peak Power Handling (Watts) 1400
Top Mount Depth (inches) 5 3/4
Bottom Mount Depth (inches) 6 7/16
Cutout Diameter or Length (inches) 9 1/16
Vas (liters) 31
Fs (Hz) 27.417
Qts 0.38
Xmax (millimeters) 14.15

Seems like it suits your criteria, its a really nice sub. I would keep it but the amp I bought packs only 200RMS for the sub channel.

probably and IDQ or Peerless Audio XXLS from what I've heard.

treo tsi 12" (200rms)
or idq? 12"(350rms)
a300.2 probably puts out close to 350rms
yal decide...remember looking for sq in a luke style box
...im feeling idq it seems

So for the idq12v2d2 they suggest a large ported box at 1.5 cu/ft tuned to 28 hz with one 3"x13.75" port

I believe that the v1 sub boxes for 12" were 2 cu/ft so i calculated a ported box this size tuned to 30hz and came up with 2-18.8" ports or 1-8.3" ports all at 3" diamater.
This seemed to give a slightly flatter response. This is all using:

these calculators are pretty awesome. Going to seal woofer to cabin and run port tube up through the rear deck.

I don't know too much about this stuff. If yal could give me your opinions on box size/number of ports/port diamater that would be awesome.

Also if i remember the acoustics are pretty screwy in an e30 so what should i be looking for a tunning frequency with this woofer and an e30?

Any help appreciated as allways

Do the number of ports/ port size really make a differance i.e. I figure the box will proably end up 2.0 c/ft for linear response. If i tuned it to 30hz for both 2.0 and a 2.5 c/ft box the 2.5 has a little peak then dip as opposed to the 2.0c/ft box for a 12" idq v2. if i was to go with 2-3" ports vs 2-4" vs 1-4" vs say 1-5" would there be a differance in sq/spl?

Sorry for all the questions i am just trying to get everything right.

Look into Dayton HO at partsexpress.com... Bu than again, what kind of music do you like, how much fabrication skills do you have, have much of your trunk are you willing to give up...

Right there is the main reason I do the boxes the way I do...after much design, several builds, years of working on different setups, the single 12 makes the best compromise of size/space/fitment/SQ and SPL in my opinion.

I just gotta find a way to build them lighter!

I have a new woofer coming soon, it weighs about 9 pounds. Neodymium magnet, about 800RMS power handling, great looks...but expensive-ish, about $325 for R3V guys.

The damn box still weighs 45 pounds though.

Might try 1/2" MDF with LOTS of braces, but then we get into cost/time factors that make things prohibitive for R3V guys. I would like to be able to do a big fat output for a total weight of 50 pounds...2 amps, single 12, box, front speakers...everything.

Time will tell though, right?

I guess lol. I am going to just go with the idq though for now i guess. People for the most part seem to like them and my amp will push it to its rms max.
