Phillip, If you find a Soundstream Mono block, for under $150 or even $200, let me know. I too am interested in finding one of those. [email protected] ------------------

The T/S parameters for the Shiva on LspCAD do not match the white paper provided by Adire? I plugged in the T/S from the LspCAD into WinISD and got some very strange results. Which is correct for the newest Shiva driver? ------------------

How does the formula change for multiple ports? Double radius? ------------------

Anthony, The Titantic even looks better in a ported enclosure. The "down low" response is better with the TT down to -6db, and the TT does it all louder. My comparison is based on a 5.16cu-ft ported enclosure. Shiva tuned to 18Hz (recommended), and TT tuned to about 16Hz. The GD of the TT...

Here is a link for flared ends for 6" ports. Link Removed Hope this helps. Good luck tracking them down. ------------------

There are tons of rave reviews for the Shiva, but not much on the Titantic. Has anyone used the Titantic driver with bad results? I have been comparing the Titantic and the Shiva two via WINISD in a 5.16 cu-ft vented enclosure (existing) tuned to 18Hz for the Shiva and 16Hz for the Titantic...

Pat: I think that most everyone will agree that you need at least matching mains and center, and surrounds if possible. The sub however does not need to match. So if that is a good price for the used Energy speaker I would snatch them up and build a sub to compliment them. You will see a...

Ben, I too am interested in speaker kits. I have yet to build any, but I am currently in the market for a center channel kit. I would be very intersted in your results, which kit are you building? ------------------

Lee, I had thought about that, but I have not given it a try. I will definitely give it a shot now, thanks for the suggestion! ------------------

Shiva-Nator Update: Final net enclosure volume: 5.16ft^3 3" in flared port tuned to 18Hz Bass Boost remove from Parts Express Amp with direction from Dan Wiggins, Adire Audio. He has been a huge help on the Shiva-Nator project. Thanks Dan! Sound Quality parameter has been achieved. Sounds...

Thanks for the support smoothe and everyone else in my time of need Progress report: The Dust Storm The name that I have given to my sub because of all the saw dust I produced when making it. Not as cool as some, but pretty descriptive. After I get it working properly, I may call it "The...

According to Greg, it looks like my formula is off by the +1 on the end. I will be taking out the bricks and tuning to 18.1Hz in the morning to see what happens. Another development. I was doing some experimenting with my main speaker size and get this: When my mains are set to "Large" I...

The formula they (Lightning Audio) uses to calculate the port length is as follows: Lv= 8466.4 X (Vr)^2 ------------------------ - 1.463 X Vr Vb X (Fb)^2 where: Lv= Vent Length 8466.4 = constant Vr = vent radius = 1.34" Vb= Enclosure volume (ft^3) = 4.8 in^3 Fb= Tuning Freq = 23Hz...

Thanks for the advice guys! I appreciate your looking at my port length, but for some reason I can't imagine that the formula that came with the port not being right. Are all flared ports created equal? The manf. knows all the nuances of the port such as flare radius, flare length, etc...

Thomas. Thanks for the quick reply! What equation did you use for the port length? The one that I used and posted is from the port manufacturer. I would assume it to be correct. Did I do the math wrong? If I take out the the bricks, the volume of the enclosure will increase, thus screwing...
