I am looking for a high quality 10" sub that has a neodinimum magnet, or has a shallow mounting depth.



It will be mounted in the parcell shelf of a BA Falcon, but the shelf will be braced and made into a 25litre sealed enclosure underneath.



The remainder of the system will be an Alpine PXA H701 processor running into into DLS Ultimate A7 amp

4 x 60rms for front stage duties and

300rms for the sub @ 4ohm

440rms for the sub @ 2ohm OR

550rms for the sub @ 1ohm



My preference is for dual 4ohm coils to get the 2ohm load



The sub will need to imntergrate with DLS Iridium or Nobelimum 6.5" midbasses up front, in very throughly deadened doors.

boston pro 10.5lf?? only needs 0.5 cubes

Yeah i had thought Boston.
Also MBV Quart Reference make a really shallow mount one RSH252

dont the ID's run in small boxes?

Yes they do.
their mounting depth of 13.5cm is a little deaper than the 11cm i have available but close enoguht for me to consider them against the others.

I am worried that any shallow 10" will simply not have enough output for a lrage car like the falcon.

Especially when I am going from 2 x 12"s with arouhnd 1,500rms.

Although it is an SQ system not an SPL system.

Why can't an SQ system have output?

Just because a system is louder than 80dB it doesn't mean it's "SPL"........

Why is the depth an issue? Is there a gas tank or something below?

What about a Lotus SW250/1 (new model) they are about 12.5 cm and suit 20L's sealed and 35L's vented and have a FS of 25hz, so they can play fairly low and the Lotus subs are known for there excellant SQ and Transient response.

Also the Peerless XLS 10" 830514 has a depth of 120mm,

technically if its purely an sq system, and the owner doesnt like to have any fun, then the sub would never need to see more than like 120-125dB

Depth is always a issue, you don't want the back of the sub too close to the back of the box, that can be detrimental to the sound quality,
25 Litres is plenty for most 10" subs, my other concern would be that in the rear parcel shelf position will be again detrimental effect in terms of output.

SQ specific subwoofers will lack output to start with, so you don't want to be handycapping them with strange placement and box shape arrangements. The volume of the box isn't the only thing you need to consider, having a long tunnel box either side of the sub doesn't equate sound wise to what it should volume wise.

Although a equal distance all around the sub for the enclose is ideal, it's unrealistic, best of both worlds is to have at least the distance of the subwoofer again behind the sub itself. Again fairly unrealistic in a car.

I imagine your trying to make a sound system that doesn't intrude into the boot drastically. although Subs in the rear parcel shelf will be possible it will be a complicated task.
possibly look at something like the critical mass subwoofers, which are designed to run in very shallow boxes with there magnets and voice coils in front of the cone rather than behind.

The biggest problem I see is, your trying to put "compromise" and "sound quality" in the same sentance.
they don't work together.....

You do need to ask yourself what is "sound quality" bass to you,
it is confusing, some people think it's simply a linear response, so a nice well designed ported box is the answer, others feel speed and accuracy is paramount which leans towards a high quality small sub in a sealed enclosure, yet others feel it's having flat to 20hz so the biggest baddest sub in a big bum sealed or ported box is the go.
And more often than not people still want it at a high volume.
each of those approaches has it's downsides.

if you wanted good depth, linear response and high accuracy and speed, a high end 8 to 10" subwoofer in a fair sized sealed enclosure would be a option, something like focal utopia 21WX or the PHD AF10W.

Alternatively if you wanted heavier output but still with decent output, something like a 10" or 12" Image Dynamics IDMAX or a JL 10W6V2 or a Boston G5 (that general kind of thing) in a sealed box, they will be a little slower, and a little less detailed, but in a boot install it won't make a great deal of difference.

if you wanted Big and DEEP bass then a nice 12/15" sub in a big ported box will give you that low and linear sound but it may come at the expense of speed and accuracy above 50hz.

sounds like a fun project.
if your interested I'm selling Both of my Focal utopia 21WX subs at the moment, they are 106mm (10.6 cm) mounting depth, Need 250-500W each, and run in a 15-30 litre sealed box, they have 208cm square of cone area, which is about 50-100cm square shy of your average 10" subwoofer, with 8.5mm of excursion (1 way, 17mm total)

1 of these will fill out the average car quite well if executed properly, 2 of them will fill a car with sound better than your average SQL 10" sub but with twice or more times the accuracy and speed.

if you think sq isnt fun mate, then it may be an idea to keep that to yourself, as others dont think loss of hearing is fun, but there is no mention of that..

Calm down Charlie, he was referring to my subs. You cant hear them, they arent that loud and blend almost perfectly.

I agree with Juls. Best bet would be a Critical Mass LS Series 12", Utopia Be or PHD. The PHD though, isnt very loud (accurate as f**k though).

Maybe try a high Qts woofer and use the rear parcel tray as a baffle (done properly of course) so you can IB off it. Ive seen a very nice example of it before, turned out quite good.

id like to see our car on a termlab matt...

dont reckon ud even get 120

Lol, Id be too scared to try. Dont wanna push my subs too hard, or they fry (been through two already..)

I prolly could get 120, but with me at the volume control, I wouldnt wanna try...

woah, you have subs?!

Rainbow makes an 8" with a fantasticly small/light basket/magnet

i dont think its made specifically for sub bass nor is it made as a midbass only driver. but ive been told it goes quite well as a subby

its called a W200 it has a mounting depth of liek 60mm it may not have the output needed but you never kno.

Some good suggestions, i will look at them all ove rthe comming weeks.

hope you didnt have to pay to get em replaced matt???

it must be hard to recoil a sub with 60 coils

Nah, twas under warranty. One was a glue failure, and the other was a burnt coil, but we managed to get it fixed. Would have been pi$$ed if I had to pay for some more, cause these things are rediculously expensive, but Yanddy treats me well.

Doesnt have 60 coils, just 6. More then enough though. Looking at its build though, its a queer unit...

if worse comes to worse.....pioneer makes a shallow mount woofer

You can build a 1.5+ cubic foot enclosure in that vehicle without loosing any boot space.
