A common equation seems to be commercial = 5-10 times cost of DIY. I think commercial budget speakers would be much closer. The more you spend the more you potentially save (particularly with larger cabs). Troels Gravesen gives the big issue as size - bigger speakers are easier to make sound better, and cheap to build DIY - but costing a fortune to manufacture, store, and ship. I would say building to an existing and well documented design or getting a kit is the way to go to minimise the risk of an expensive white elephant.

The crossover will definately need to change. This DS-215 does look like a good option from the Dayton range.
Hi Andrew, when you simulated the drivers did you get the DS-215 data ?? I read you mentioning an aluminum cone woofer and I am confused. There is one DS-215 and one DA-215. I want to be sure you did it with the DS-215. The DS-215 isn't an aluminum cone woofer. Thank for all your help.

Kind of interesting Troels never had any tall slim designs (actually he might have had one but the design was probably not very optimal). I keep telling him that he needs to improve the look of his designs.

I am almost certain it was the DS215 data I captured (I must have got confused over which driver was the aluminium one). However I am away from home with work in Romania at the moment and all the CAD files are on my home PC. I will be back on Friday and can make sure then. Also I think I sent you the screen grabs I used to input the data so you check on those and compare with the data sheets to see which one I inputted.

He does look for the tall-slim floorstanders.

Hi, I just checked the original downloaded Zip file from the Dayton site and it is definitely the DS-215 that I used the data for sorry for any confusion my referencing aluminium drivers cause.
