Sub Box Enclosure

Deutscher · #1 08-09-2008, 11:17 PM

Hi guys,

Just received my items from ebay

I've got the Hifonic Olympus 2412 (2400rms, 12") sub and need a box to put it in. Reading the manual, it says it is not recommended for closed box designs but also has different types of boxes.

Standard Tight Base - 2/56.63 (cubic feet/liters)
Optimal Sound Quality-Flat Response - 2.5/70.79 (cubic feet/liters)
SPL Very Boomie-Loud - 2.75/77.87 (cubic feet/liters)

Which would I go for?

Have you considered a boc that extends your bass responses? For everyday purposes I rarely recommend an SPL enclosure. You will hate it except for when you that particular note

umm, flat response would kinda be the logical choice.

do you actually have the t/s specs for the sub?

^^^not always. The woofer in question here is a highpowered monster designed for SPL set-ups. Considering it's not going to be used in an SPL set-up more of a daily driver it's never going to have SQ abilities.

yes, but if you're using the sub to play MUSIC, you're going to want a box that gives the flattest possible frequency response so it can play music as accuratly as possible.

edit: I never said anything whatsoever about sound quality, I said flat frequency response.

Flat Response = Sound Quality.

I'm not too sure which I want. It will be a every day driver. I know you guys don't know what I want, I was wondering what you guys would do. A do like volume, but I don't want to lose quality.

How much difference (in db) would a SPL box and flat response be? is it going to be noticable?

I voted for MY preference - that's all!

(flat response)

Seriously Mate, it depends on what YOU want - but as Ray pointed out, when set up for SPL it only works at peak efficiency at a very narrow feequency band - for general listening it's dreadful.

Also, look at the size of the SPL box! by the time you allow for back-volume, port volume, and bracing, you're well over 100 litres!

It'll weigh a ton, and take up half your boot! Although, even the box volume for the flat response is large - it would seem this driver has relatively tight mechanical suspension, not relying on the compression within the enclosure for cone support...

Hmmm, I'm starting to ramble....

Cheerz, later!

I'm thinking of going with flat response or tight bass. From what I hear, SPL is not the way to go. About the boot space.... I barely have any left haha, I've got a gas tank in the boot, don't use my boot tho so its only for my amps and sub. Weighing a tonne.... it already does, for some reason this sub is hell heavy lol, not like my Type R I previously had.

Heh - sounds like an industrial duty unit!

Good luck with the project.

The Kicker 0gauge wiring kit weighs 6Kg
The Hifonic Brutus amp weighs 7Kg
The Hifonic Olympus sub weighs 17.5Kg (without box)

Too me that is heaps heavy!

As far as difference in dbs go i would imagine something like 5-8db...depending on how well the box is tuned if its a SPL box.

Which would make a difference to how loud it goes. As stated above, it'll only sound good with a handful of songs.

Id say if your not after a system that you wanna compete (at SPL comps) with and are concerned about box volume / size, go with the sealed version. It wont be as loud as a ported box but will sound good with all music and be relatively small / light.

A sealed box, provided its the correct volume, will also give you a flat frequency response and therefore decent sound quality.
