Re: Rise of the Eighteens

The latest batch of Maelstrom-X are dual 2-ohm.

Just a thought... for those that might come up with a good reason to go sealed.
A couple of questions...What is your budget for the drivers? Are you adverse to more than 2 drivers or other combinations of sizes of drivers?

I would say that the Mal-x would be the top choice for a big double 18 EBS, but there's no 2 or 8ohm model. After that I personally like the RLP18 a bit better than the Q18, but that's just me. I think that Scott's design would be a good idea. His are 25cu ft each RLP's tuned to 11hz each with 8" ports and he also uses a bridged EP2500. If you tune to around 12-13hz each RLP should be fine with it's half of full power from the amp(figure 1000w each on peaks). Q18 is pretty similar really.

Re: Rise of the Eighteens

Sonnie,

Is it possible to consider dual amps? A better experience and more headroom. Your room isn't small. I have dual LLTs in half the size of your room, and just enough. With that space I would consider some serious woofing and power.

I agree with you about the RL-P18. Pls note this sub takes 2000 W+ in my setup without any problem. I would even say it likes to be given some homework

Re: Rise of the Eighteens

If I went with dual amps then I could go with the dual Maelstrom-X's. That would be impressive indeed.

I would like to stay with just 2 drivers. I will already have a pair of 15's in the front. I have the one Audiopulse now and will probably do another one of those for the other sub in the front. So I am going to have 4 subs altogether. Of course then I am going to have the same dilemma with the dual fronts as I am the back... those are dual 2 ohm drivers. I can't win here.

Re: Rise of the Eighteens

That's going to be a lot of bass Sonnie. Well ... I vote for Mal-X's if you get more power and the RLP's if you stay with a single EP2500. Do you already have the EP2500 to use for this project?

Re: Rise of the Eighteens

Do you have something to play with phase? You will certainly need to adjust subs phase since they will be far from each other

Re: Rise of the Eighteens

They will be right at equal distance from the main listening position, so phase should not be an issue. At least it wasn't in my last setup which had a very similar sub setup. I tried phase in 15 degree increments to 180 and 0 ended up being the best.

Re: Rise of the Eighteens

At equal distance you should be fine, but but but if they are far apart (4ft+) from each other, they might not couple up to 80 Hz. Anyway give it a try and we'll see.

Re: Rise of the Eighteens

Sonnie, I vote the Mal-X's, but hey I'm a bit partial.....

Just to be sure, this run of them is Single 4ohm VC, Kevin has stated the next run will be dual 2ohm for more flexibility. The upper bass response on these babies is spectacular... What mains will you be running with your new sub configuration....?

Any hints on what the size of your new HT will be... configuration...
