Which 6"/6.5" sub for rear doors?

[Shaun]

I own an Audi A4 Avant (B5). This is an estate/station wagon. I recently upgraded the head unit and front speakers. Although I changed the woofers from 4" to 5.25" (Infinity Reference series), there is still a lot of bass lacking. I have now configured the head unit to send the LF to the speakers in the rear doors; the front speakers are HP'ed. This has improved the sound quite a bit, with the rears putting out slightly better than expected bass, although this is still just a stopgap.

Now, I don't want to mess with the aesthetics of the car, so the original grills are to be retained, and there can be no extra boxes in the car. My intention is to use the rear doors to house one 6" subwoofer each (driven by separate amp).

Any recommendations for a sub of this size that will work well in the door (sealed) cavity?

Adire Extremis's...not exactly subwoofers, but very potent midbasses.

Or Elemental Designs EU-700's, which are true subwoofers.

Tang Band makes a 6.5" sub, IIRC...available at Parts Express.

Hope this helps.

I have both the TB W6-1139 and the Adire Extremis. If you are going to be using a separate amp I think the decision comes down to what your XO point is going to be. For sheer bass, they are about equal but the Adire will cover the mids better. If you only plan to use it to 200Hz or so the TB is a little cheaper but it has a stamped basket vs the Extremis' cast. I like both woofers equally but for different reasons. Although one is called a 6.5 and the other a 6.8 the outside of the basket is identical.

Hello

You could check if the rear door panel for your Audi to see if it allows the installation of 8" midbass speakers.

8 inch midbass, or even 8" subwoofers are sometimes installed on rear door panels to provide extra bass for those not wishing to get a full fledged sub and enclosure in their rides.

Have a look see whether the mounting panel allows an 8" midbass/subwoofer to go in.

hmm, I was shopping today for a replacement for the doorspeakers for an audi (A2 and A3 sportswagon, yes, in principle for both of them)

Unfortunatley to no avail, either they want to sell crap or they want to sell something like 600€ plus for a set of two

From the standard units the bass is too sloppy.
I wanted to look at Focal polyglass, Hertz energy serie, DLS C6, Helix etc.

Call, is the adire extremis also available in 4ohm, I have found only an 8ohm version

Hi I'm looking for a pair of 6.5" woofers for rear fill in my car as well.

Looking at the Tang Bang W6-1130 and Adire Extremis 6.8", I note that the Tang Bangs optimal sealed volume is 4.2 litres unstuffed whereas the Extremis recommends 9.5 litres fully stuffed.

My question is, how much internal volume does a car door usually have? Would the Extremis's parameters make it unsuitable as a car woofer?

Thanks

I belive the 4 ohm version is on it's way and will be known as the Extremis 6.4. Can't tell you when though, these are little tidbits I pick up by eavesdropping and poking my nose around.

I emailed Tang Bang tech support concerning the use of W6-1130 in the car door, and their reply is that the high mounting depth requirement makes it unlikely that it could be used in the door.

Most people buy wagons for cargo ability as oppossed to aethetics. I would consider an enclosure, even if a small one. Audi is a great car but those doors are a far cry from a sealed enclosure.

Check out Morel drivers. The MW167 would work. But you really should consider a small sub and amp.

# 6” Damped polymer cone woofer
# High flux neodymium magnet system
# Hexatech voice coil
# Copper lining of VC gap for flatter inductance
# Flange 160mm (6.3”)
# Cut-out 136mm (5.35”)
# Depth 65mm (2.55”

There are a few companies that made inverted magnets on small subs. Also there is a company that sells a processor that claims to "trick" your ears into hearing lower octaves by emphasising select higher ones.

Hi, angeloPB

I bought this one more for cargo potential (when I need to lug my speakers around ). It is primarily a family car, and I am trying to retain the authentic look and feel as far as possible (I've already left my mark on the lounge, what with the mismatched look of the HT speakers .

Audi is a great car but those doors are a far cry from a sealed enclosure.

The MW167 would work.

Would you mind explaining your choice? I guess it must have something to do with your comment about the leakiness of the door. But I had imagined a driver with a higher Qts.
