15" 8" 1"

We have to have a 'list price' to start with on any product, but there is generally some scope for deals. Its very hard to work your way up if you start with the bottom price. Its much easier to work down.

We did select some high quality components for the HF section, you can substitute cheaper components and still get a good result. The Beyma CP385Nd nudges the price up a fair bit, in my opinion it's worth it - I realise others may not share the same opinion so there are other options. For example if you are happier with lower power, the Faital Pro HF100 does a good job, and its not at all expensive.

The design will work with most 15" drivers that are designed for mid-bass, I've tested the box with numerous 15" drivers and had more than acceptable results - we chose a few of our favourites to make some packs up with, but it is really easy to chop and change parts. The P-Audio 15BM-500B works fine, as do several Precision Devices drivers. Most of our choices were higher power 15s as they will keep up with the 8" better. We were getting sensitivities of around 105dB on the mid-horn, if you chuck a 400W 15" in the box it will run out of steam well before the 8", but that doesnt mean you cant do it, we were just aiming for maximum power handling in this design.

I have been trying to find time to publish all my test results, but not managed to find it yet! I will get this done soon, and this will include a few more options on the 15" and comp driver.
