Are you speaking of the X1 cabinet in speakerplans?

HAve you considered push pull slot load yet? Lots of advantages for a little more volume and complexity.

you sea OHM AUDIO 2*18 very good p pressure

Re: Building 4 Dual 18 boxes, help needed and build thread

Thanks for the compliments.
We (mainly my dad) are experience cabinet makers/wood workers... (and metal)

If anyone is interested in the 4x8 layouts shoot me a msg.
Takes about 3.5 sheets for 2 boxes

Re: Building 4 Dual 18 boxes, help needed and build thread

Very fine woodworking. It's great to see that.

Do you have any experience with the "road-worthiness" of the subject material?

Again; superb craftsmanship & great work.

Best of luck.

Havent had them down the "tough" road yet as it is brand new and have been delicate with them. They are however double coated in DuraTex. Id guess it will be a couple years before I start seeing any real signs of abuse (wrt to the wood). The grills are 18ga mill finish 304 Stainless Steel.

Re: Building 4 Dual 18 boxes, help needed and build thread

Sorry about that. I misspoke about my own boxes. They are made with Sandeply (made by Endesa), NOT Arucaply.

Since this thread is pretty recent and discuss the use of Arucaply and the infamous Gsub, I figured I would share my recent build. Arucaply works very well. The box is for Lowrider 18s....

Nice clean build. I liked the use of pocket screws.

that doesn't distract me from the real world implications of damage caused by amplifier clipping.

There is no damage caused to woofers by amplifier clipping, nor do drivers require a minimum drive voltage to 'bring them to life'. They just won't play as loudly as they would when driven to full excursion.

Re: Building 4 Dual 18 boxes, help needed and build thread

Amplifier clipping will not hurt a subwoofer, if excessive average power and/or repeated overexcursion are not applied. They are underpowered, but that means the amps could be upgraded later without redoing everything. Or leave the low powered ones in when you've got some DJ who like to turn it up to 11.

The Kilomax's aren't that good a driver. The Defini's are better, as are equally priced B&C, RCF, etc.

Re: Building 4 Dual 18 boxes, help needed and build thread

Given the amplifier power available I question the use of that many fancy and expensive "difini" drivers. There's going to be a lot left on the table with that much invested in drivers and not enough clean power to bring them to "life." I realise that the drivers will run out of Xmax at probably half their thermal rating in a typical box, but that doesn't distract me from the real world implications of damage caused by amplifier clipping. For 8x difini/kilomax type drivers, I would want 10,000W RMS of clean power on tap.

I suspect that the drivers that are there could be re-boxed to produce a more desirable result. I also think that for the same price, the kilomax looks better on paper than the difinimax. (More Xmax and thermal headroom). There may be something there that I am not seeing from the "on paper" approach but that's just my gut feeling here. Regardless of that opinion, I think there are a handful of drivers at about half the cost that are more appropriate for the level of amplification available.

Re: Building 4 Dual 18 boxes, help needed and build thread

I think the G Sub will be too small for the drivers the OP plans to use. The Eminence 18" drivers tend to like a very large box when tuned low, because while they are very economical drivers, they don't have the most powerful motor structures. A customized design for the Eminence drivers will give the best low bass performance.

Before building the G Subs with these drivers, be sure to simulate the performance of the Eminence drivers will be satisfactory in the box. Don't just assume.

Yes yes, I appreciate your concern and thoroughness here but I'm far from a newb. I'll actually even one up it and break in a couple of the woofers and put them on my woofer tester to arrive at a more accurate model...

Re: Building 4 Dual 18 boxes, help needed and build thread

the G sub over at speakerplans.com seems to be a good design. may have to adjust the port for the speakers you plan to use.

Yup that's basically the design I would be doing. Thanks!
