We need to know the Xmax of the subs, whether it's 8 mm or 18 mm will determine what can be done with them.

Sonotube suppliers (called formatube or form tube here in Aus I think)

Genuine Sonotube (I have been informed): Bower & Lever or Hudson's hardware (Bower & Lever were cheaper though).

Bower & Lever
37 Victoria St
Windsor
Brisbane
Ph:3857-2018
(Hudson's Hardware dearer - quoted $355 for 762 x 3metre length)

Open:
6am-4.30pm weekdays
6.30am-11am Saturdays

About 13mm thick walls
Internal diameters:
610mm x 3 metre = $210.61
610mm x 6 metre = $285.51
762mm x 3metre = $314.92

Delivery = $44

These prices were valid about this time last year - probably dearer now

Hope that helps?

By the way - I have 4 jaycar bass shakers (2 x 2 units wired in series) and use and old NAD amp to power them (sacrilege I know). Works very well though and is especially popular with the neighbours.

As for amps for the sub - can't go past the Berhinger EP1500 or EP2500 for value for money - DJ-warehouse and/or New-Media are probably the cheapest suppliers in Aus at the moment.

Bad news. There is no way these can be used for HT. They are impossible to model ported, and in 3 cu.ft sealed they would take 30 watts to reach Xmax and output drops fast below 50 hz. These are only for car audio and not even good in that application. Sell them, get what you can for them and put the money towards a better sub.

thats ok Mike thanks anyway i only paid $60 for them inc shipping. I like the Mach 5 Audio IXL 18" subwoofer or 12" subwoofer what will give me the best bass for movies? and what size sonotube would you recomend for both applications. Cheers Troy

**Mike P.** · **05-07-09, 10:58 AM**

How big is the room and is it open to other areas? Would a 13 cu.ft. sonotube be acceptable if you go with a IXL-18?

**SAY IT LOUD** · **05-07-09, 11:29 PM**

I have a dedicated home theatre room with one door 6 metres long and 5 mertres wide. I am going to put home theatre velvet curtains around the room with no shine or lustre im leaning towards matt black and the ceiling will be painted dark grey.

13 cu.ft is too big. the ED subs look very solid with great TPS and xmax now i dont know so can you please advise me of the better sub i will stay with 12" or 15" if i can get away with it.

**Mike P.** · **05-08-09, 01:14 AM**

What's the biggest size that would be acceptable?
Are you willing to build a box or do you want to use sonotubes?
What's your budget for subs and amp?
