Re: Rise of the Eighteens

And why are you concerned with the limits of this system? You are easily at reference even without room gain. This system will newer see more than 10% of the rated power unless you are a total nutcase. This system will create earthquakes!

Having said that, I can totally see why you do it!

My only question is why are you set on using a 10hz highpass?

I am not "set" on anything. I was simply showing it for a comparison.

Yeah... agree. Limits are mainly for comparison sake as well. We could back it down to 3-400 watts... the plot doesn't change as far as the differential of the comparison.

Re: Rise of the Eighteens

Sonnie - are you going to keep the Behemoth LLT in the HT room or is it going to find a new home in the main part of the house? This is going to be incredible with the newly planned 4 18's plus 2 or 4 15's. The neighbors may think different when their pictures fly off the walls.

BTW - your HT room looks great. It appears a lot of planning went into its design and construction.

Re: Rise of the Eighteens

The Behemoth is no more...

I should have kept it, although if I had of kept it, I would not be doing the 18's.

See... I tore out the old HT room because it was too small and we could not heat/cool it properly. I thought I had done a good job planning, but there were some unknown variables, which at the time did not seem too important... not nearly as important as they ended up being in the end. So... we decided we would tear it out and one day do it right. That one day is coming a little sooner than anticipated. Lucky me...

This is debateable, but mostly true and I would agree. However if the first three words of your sentence are removed it becomes un-true.

That's akin to saying car A can drive further than car B using the same amount of gas. But car B can drive further than car A when car B gets to use more gas. I'd certainly hope it can.

Re: Rise of the Eighteens

So how do I decide which will ultimately be best?

Excursion, air port velocity, nor first port resonance are an issue.

So much to work with and so many choices.

Heh. I just had to. Somebody does

Exactly right. Gas = enclosure size so that Car B = the ported system and Car A = sealed system.

Of course you were equating it this way. Gas = Amount of drivers. Car A = ported. Car B = sealed.
