I believe B&W makes their own drivers. This would make it difficult to match exactly. However, the good news is that B&W are pretty neutral and if anything have 'tight' bass. So provided you try to match up a DIY speaker with the same type of criteria you might be in good shape. My choice...

Wait a second. Xmax of about 5mm? Hopefully you didn't pay very much for this. Based on the power handling of this driver, I'd suspect its not a very efficient driver. This Adire Shiva (approx. $180 canadian from creativesound.ca) has a 31mm Xmax and power handling of ~500W?. Now, its...

For a cheap sub.. search around for a used SVS driver.

Ted, can you comment on how 'compatible' the Paladin crimp die is with the Canare? (I believe that you did use them successfully, but what lead you to believe that they were fully compatible?) Roo

> but the expensive tools seem to be a necessity. From what I've read on the web -- it seems that Canare is one of the few 'crimp type' connectors that does it right. So while there may be other crip connectors, they are not as good as the Canare by far. You can use the solder type...

I have a set of the older Anthem MCA II series (the MCA2 and the MCA3) providing 5 channels of power. Before I bought, I was able to borrow the MCA5 to 'demo' -- which I did against a Bryston 3B (stereo comparison only). I would urge you to demo the amp at home in your system, shop around...

James, go to Rona in Ottawa (merivale & huntclub). They sell smaller cuts of most wood. The recommendation is to use a board of the same size as your projector, even though the mount point is a lot smaller surface area. The reason to use a larger surface area board is to spread the weight...

Unless you have already found the 5" diameter pipe for your port, you might reconsider. I couldn't locate any easily in my area. I ended up using a 4" port and it is fine -- I've never had any port noise problems, but I listen to things at a reasonable level. You could always move to a 6"...

Might want to give the Jon Risch recipe a try. ThomasW, could you be specific on which Jon Risch recipe? His website shows a progression through various types of cable, to using two cores and twisting them. There is also a website www.diycable.com that sells kit form versions of his stuff...

My thinkpad 600x seems to have a full duplex card. Roo

I'd just like to chime in here. I'm not a believer in high cost exotic power cords, damping pads, interconnects. However, there is an obvious build quality between really cheap wires and well built ones. At the very least, they'll put up to more abuse. I don't think David F. has gone...

The RS SPL meter has a built in 'amplifier' for the signal on the RCA output jack. This is the reason that you should be using the line-in on your sound card. I found that the amplified signal was pretty 'hot' compared to what my soundcard was expecting. So, when measuring using the SPL...

Hum can be introduced in the system from a lot of sources. Any physical connection might be involved. For example, many people have trouble with their cable TV connection (into the VCR, VCR into Receiver.. hum) To debug the problem, unplug everything.. and then slowly add back in...

I believe that version of the Sony does not pass blacker than black. The original Sony 7000 did, the updated 7700 did not. (this is from memory -- I may be wrong). AVIA contains a pattern that gives you a way to set black levek without blacker than black. Even with VE, you can use the gray...

You might look around locally.. someone may be able to give you a good price: http://www.fleetsound.com/ (I haven't used them, but I did locate them in your area during my pro amp hunt) I ended up dealing with: http://www.humbuckermusic.com/ Who I found to be very professional, and had...

I wrote up a basic "getting started" for lspCAD directly related to my building of a sonotube sub. www.quux.net/roo/diy/sonosub Roo

There are also benefits to using a downfiring design for some driver designs. The Adire Shiva actually will have more "excursion" if used in a downfiring design. So, down or front, the design of your enclosure, design goals, and driver selection (even your amp) all have a factor. Sound...
