Full Version: Help: Suggestions on shallow mount subs
Mobile Electronics Australia > Mobile Electronics Discussion > Sound Quality Discussion

I need a high end SQ oriented sub that is less than 5 inches deep, but will still play with authority unlike some shallow subs. Open to suggestions regarding brands and diameters. I have between 1 and 1.3 cubic feet of space for the enclosure, and would prefer an impedance lower than 4 ohms. I have been considering the following, so if anyone can offer advice...

Alto Mobile Falstaff
Phase Linear Aliante
JL C5
PPI Pro

A few of these are old school I know, so please suggest any others smile.gif

If you can get your hands on an Aliante 15, it will easily stomp on all the others. The Falstaff (never played with it myself) is reputably a disappointment and not in the same league as the others. The PPI was a phenomenal sub in its day, but you can get nicer ones these days.

Kenwood and Pioneer do shallow mount subs now as well as RE Audio smile.gif

I run Earthquake shallow subs 2x10" in a very shallow enclouser in my single cab ute.When i bought these subs they where the only shallow subs avalable in OZEathquake shallow subs pioneer six month wait.as box only 5" deep and 1.1 cubic feet these subs work well.Using a box that i designed and built these subs and focal 4" splits i am proud of my second place in ametur class in my first sq event.

Why do they have to be shallow?

your really against shallow mount subs hay phil lol

Most (if not all) shallow subs tend to be pistonic in nature.

The Piston is, at least in theory, the best way to propagate acoustic waves evenly without problems commonly associated with cones or domes (in regards to sound wave detachment from the driven element). Its the closest you'll get to a point source, at such a large size.

That, and they're shallow. smile.gif

Phil is simply trying to convey that, if done properly, you should be able to fit a conventional driver in a small space. And he's right too. But Pistonic subs have their own unique sound too, which some of us really like!! tongue.gif

From Lambos to MR2s, I've never built a system that needed a "shallow" sub. The enclosure volume is always the issue, not the sub mounting depth.

A lot of companies seem to be making subs to satisfy a need that imo doesn't exist......

My car is a honda prelude gen 5. While I was running the cables for my new install I had a closer look at the panel in the passenger foot well. For anyone not familiar, there is a panel mounted diagonally in the footwell with electricals mounted underneath. The depth is about 4-5 inches, and the height and width are decent. I could fit up to a 12 easily, and possibly squeeze in a 15 (although a bit overkill, but worth considering).

The aim would be to mount the sub facing the passenger but with a solid MDF baffle across the face, making the enclosure appear almost like a bandpass/slot port look (I cant think of a better way of explaining it). I dont want to drastically alter the shape of the carpet as I want to retain a stock appearence, so can not go much deeper than the specified space.

Please offer any advice/criticism, as at this stage it is just a thought that I would like to develop and test.

Thanks, Dan.

There won't be enough enclosure volume there, sorry. Again no need for a shallow woofer.

Where do you go abouts getting a Phase Linear Aliante from? If you're looking at buying from overseas, I'd be willing to split postage costs if you got a few.

phase linear is no more.

check the website for aliante

as for getting one.. well thats another matter..

Phil, please explain how around 1 cubic feet is inadequate room for a sub? And please, if you can suggest a sub that will fit my requirements, then do so. As I originally stated, the mounting depth available would be limited to around 5 inches, in your opinion what products should I be auditioning?

I know phase linear are no more, I would be looking at second hand with any of the brands I mentioned. I would much rather buy a new sub that will suit the requirements, the list I provided was just the models I could think of that would do the job, I am sure there are many others, hence the reason for my post.

Please, any advice would be greatly appreciated.

So you can fit a box 20"x20"x5" in the foot well? This gives 1.15 cubic feet gross, or around 1 cube net.

I'd be willing to bet you'd be lucky to fit a box 12"x14"x5", more like 0.35 cubic feet net.

As I said, it's never the sub's depth that's the problem.

Too true, too true. However, Mac Audio have picked up the design and build. Dunno about how comparable they are to each other though.

Phil, on taking measurements the enclosure would be 48cm x 37cm x 14cm, so a gross volume of about 0.9 cubic feet. While this is slightly less than I had originally hoped for, it is more than adequate for a great many subs out there.

I really like the thought of the new RE slim sub, very impressive. Does anyone have any info regarding specs and dealers?

If you have a tiny enclosure, try going Aperiodic Enclosure.

Enables you to run a MUCH smaller enclosure space whilst maintaining critical damping levels.
