Yes, the coverage is technically even. They are a HIGH efficiency speaker. With good drivers the sound is clear and powerful. We're talking a physical presence to the sound here. I had a friend that explained they weren't room filling speakers, they were house filling speakers. All with very little power being used by the amplifier. This also means if you have a fairly low powered amplifier you can use these speakers.

Wayne mentioned you need corners. You should also be aware that these are physically large speakers (check out the dimensions on the price list).

Then there is the dollars verses performance issue. For the bucks these speakers give you A LOT of performance.

Another issue is difficulty of build. If you can build a box, you can build these speakers. They are at a very different build level than say Waynes Pi 12 speakers which have a lot more pieces and angles or Bill Fitzmaurice's speakers.

Plans from Wayne are free still I think (can't lose there).

Support on the forum is great when you have questions.

You could probably decide to throw together a box yourself that would work. Wayne has had this design around for quite a while though and has had a lot of time to get it right. If you decide to build them you may want to look at the kit prices, or at a minimum check out the crossovers available on this site. Wayne builds his own crossovers which are quite good.

Happy building whatever option you choose.

Grant.
