I seem to have no real luck with the speaker design programs, can someone post what the sonosub charts and numbers would be for the 15" and the new 18" UM Dayton speakers would look like? Oh, with 500 watts if that matters.

Hey guys! I was wondering a couple things. Have any of you used dynamat for building an enclosure, to add damping to the enclosure itself?(sub, or speakers). Or would this be wasted due to the mostly good damping effects of MDF? (Assuming MDF as the most popular material) And also, anyone know...

Ci sono, sono sempre qui Gianni

Hello everyone, been lurking around this site for a few years, and have finally decided to register. Ive been checking out the very nice builds on this site and decided to try one of my own, but ran into a few problems. I was wanting to build a sonotub with a subwoofer that was given to me , but...

I'm playing around with Sonosub.exe and winISD and have come up with some measurements. A few questions: First: The area after(lower) the tune frequency, should I put much thought into this ? I was under the impression that below the tune frequency, distortion rises quickly. So for example...

Has anyone successfully integrated a plate amp into the tube

Can someone help me out and explain to me the different sound I can get from different lengths and diameters of a port for a ported Sono Sub??? Im really confused

I have been wanting a sub that will reach extremely deep and yet not be a massive cabinet. I know with a sub that is small I will need alot of power so I started to search for many many different designs and after chatting with Bossabass on the AVS forum I decided to try and build a sonotube...

I wanna put 2 10inch subs in one tube that's 40 inches high...does that sound rational?

Sooooo am in the middle of building the sub for my home theater to go in our newly renovated living room and my wife said that the only way its going in is if she can decorate it with some of her decorative plants. Putting port on top is now out of the question. What do you guys think of...

I am starting this build project and will post pictures showing the progression. These will be 2 15" Dayton Titanic MK III with Exodus Audio PR 18 passive radiators in a 5 cu ft Sonotube 40". I am doing this project along with building a new rack stand for all the components and the TV. If...

Hi i have recently bought 2 RE SXX18 D2's after waiting 9 months for RLP 18's. Here are the TSP could someone please :dontknow::dontknow:tell me the enclosure size i was thinking of useing 22" tube. RE SXX18 D2 Mounting Depth - *9.5" Mounting Hole Diameter - *16.75" Overall Diameter...

I know this has been discussed several times before...but I never really saw a strong conclusion on this. I know that some sonosubs need to be almost floor to ceiling in height. The calculator even tells you how much room you need to stand it up. However if you have a sono sub that is almost...

Hi all. I'm new to the Shack but have been hanging around AVS Forum and HT Guide for a long time. I see this site as the best place for DIY Subwoofer help. So anyway, onto the fun. I just purchased a 6' section of 28" ID Sonotube and 5' of 8" ID Sonotube from a local supplier. I have a home...

I have 2 700 liter sono subs using Fi Q18's and an EP2500. Detailed more in the Fi forum. In my fight (or quest) to get audyssey to play nice, I tried plugging the ports by wrapping beach towels tightly and stuffing them in the ports. It helped Audyssey to "play" better (that is a discussion...

I have a sono build that uses an Avalanche 18. The sonotube is 30" diameter and from bottom end cap to top endcap measures 54.5". The Length across the endcaps is 32". Now I had my brother in law build this as I am terrible at DIY with no skills. So as of now I believe it's tuned to 16Hz. I'm...

This is a 16.5 cu/ft sonotube tuned to 16.5hz with an 8" sonotube port. I am using two Maelstrom-X subs for drivers. They are 24" sono tubes. This is my first sono build. The pics are of my wife standing next to the tubes, and a few build pics. This is the extent of day one. I am trying to...

The person I spoke with at PP said they had not done any flow testing with their 6" PP VS an 8" sono port-(straight or with roundover). Any one here had direct exprerience with one over the other? Things get a little close behind the driver if I use the 8" (box is 24" deep and 22" high and...

I apolagize...I ramble but I type what I think. I am contemplating building a sonosub or two for the house that my wife and I will be renting. The threads I have found have answered alot of questions...however I still have a few. It will need to fit behind my TV stand. (40" from floor to top...

Dual Q18's in 700l Sonotubes tuned to 12.8Hz 30" Sonotubes cut to 67" and 8.4" ports cut to 31.25". Well, it all started innocently enough. I found that moving my living room HT stuff to a more dedicated basement HT enviroment lost a lot of bass. Research brought me here. I enjoy doing DIY...
