Also.....what do these sono tubes cost???

Are the big ones all standard size or are there many different sizes?'
The program is saying I need one with 1' 10 internal diameter. But no matter what I change it always says that size...

You can change the sontube diameter also. I put in 1'8 since I'll be using 20" diameter.

Most use large ports like 6" so you don't need many smaller ones. You can use flared or non-flared. Flared of some type helps the air flow and lessens turbulence.

Sonotube varies in price greatly. Most of the chain home stores don't carry anything above 12" now. If you have a concrete supplier near youm they will stock a plethora of sizes. I have not priced any recently but I am guessing you will have $65-$100 in something 16" or larger.

You should be able to alternate the settings in the calculator to enable changing the tube diameter.

So how does one find the Optimum tube diameter and volume....

There is no optimum per se, just preference.

Once you settle on a driver and tuning point, then you have your approximate volume. Then, you select that diameter that works for, obviously, the less diameter, the more height....

Thats kinda what I wasn't sure about.

I know that if you add diameter you can have less height....I just didn't know how that affected performance.

meaning....would a skinnier/taller tube work better than a Fatter/shorter tube...or visa versa...


I mean I could get a 20inch tube that would be taller....or say a 24inch tube that would be shorter...

That is almost entirely a preference thing. I prefer a tube that has good proportions, and I think my 48" tall (just the tube itself) 24" diameter tube looks right. I am not a fan of the realllly tall skinny ones. But hey, it is what you want to to do that matters.

No performance differences per se, just length and girth. Of course, at a certain point the tube can become so short and fat that it won't accomdate the necessary port tube.

First, find out what you have access to. If you can only get 24" then modeling with 18" or 30" is pointless...
post #68 of 81
Hmm, if you did an 18"er your dimensions would be 24" sono and 66" tall, is this too much?

Ya....66' tall is just too much. My basement is small with a lower ceiling than most...(probably only 6.5ft high).

Thats the reason I'm going with a 15.

I can build a SONO slightly larger than my current 16-46+ but now I can have a 15inch woofer thats every bit as good as the Plus woofer, but LARGER and tuned to perfection Oh ya...for a lot less than $900 too!!


If this one goes well, when I move to a larger house with a 100% dedicated room that is solely designed for a HT......Maybe I'll build an 18inch monster

True, the 15 is still a great option, good luck!

Not to mention that the TC2000 is a much better driver than the plus series. That coupled with more power and more displacement is a substantial difference.

Better driver than the RL-Ps? Not necessarily.

Uhh, I was referring to SVS Plus series driver vs. TC-2000.

Sorry, completely missed the ball on that one.

No problem!

I can't understand why, only a dozen threads simultaneously talking drivers.

It is, depending on what the user is looking for.
post #77 of 81
I was referring to the RL-P18, because that was what I had originally recommended but he said he didn't have room, then jpmst said that the tc was better anyway, I thought he was referring to the RL-P18 and he was really referring to the SVS plus's.

You can grab 8 inch od (7.5 id) sono for about $5 per 4ft tube. No chance for cuffing with that big boy. Only recommended with the 24" sono though.

Wow a 7.5inch (ID) port....that would be HUGE!

I'll have to play around with the calculator to see how that affects port length and tuning

Check out some new waterfalls from kweezr. Hitchikers Guide to the Galaxy is the new king of bass. WOTW is for wimps. Time to make a new measurement thread in the sub forum
