Axiom Home Page Forums General Discussion Home Theater crazy idea, need some input

Yeah, make it 18 so it's legal.

Take it from Charles. He learned the hard way that 15 will get you 20!

Prison cell acoustics are no picnic, either. I had to dismember my cellmate and use him as acoustical treatments.

If it was me moving into an apartment I would get a Paradigm DSP 3100. It is small, sounds great and shouldn't bother the neighbors too much.

You have to work with the materials at hand. Good for you.

Sam. I would strongly recommend making the visit to homwtheatershack. There are lots of very experienced DIYers that can help you sort through all the design stuff and there is a great program, winisd, for modeling drivers.

There are a couple of guys on the forum who will help you with the modeling. All you need it the T/S parameters of the drivers you are considering. this will allow you to compare the performance of drivers given your restrictions.

Here is an example of the type of resource the shack is. Its a build thread for an 18" Mal-x with passive radiators: massive output in a reasonably sized package.

Yeah, I have been frequenting HTShack, AVS, etc for a while now. I don't think I would be attempting this if I hadn't been silently been observing the amazing work, and feedback, of others. Thankfully the modeling is pretty straight forward with a sealed enclosure and I've already worked the numbers out.

The paper drivers present an interesting option. They have lower SPL at high power than metal drivers, and require less power (370watt rather than 600watt), resulting in a tad less overall vibration. Considering for the immediate future I will not be pushing the sub tremendously hard, I am tempted to see if this idea may work (not the TV part, just the mounting the VP150 in a connected vibration-dampened upper compartment). The design is modular, so the worst case scenario is simply a dual 12" driver setup, with a wall mounted VP150 above... I can live with that
