That's pretty much right. The more flexible the axo is the more success you'll have though.

Default Your setup!

The only problem that might present itself as I see is the reflections caused by mounting the mid and tweet on a large flat surface board. As you go up in frequency the drivers need less and less flat surface. Flat mounting surface causes reflections and it can be clearly seen in 3d waterfall displays. The ideal would be an arc curved surface or no surface at all especially for the tweeter. The woofer is the only driver that needs baffling and it needs to be up off the floor which causes reflections at least 24 inches or more off the floor. Ray Hughes

keeping your mid at ear level when seated works very well. Best regards Moray James.

Default This woofer has an interesting Qts..

of around .30 which makes it very adaptable to Thiel-Small vented box parameters. Don't know if it's efficiency rating matches your mid and tweet. Don't know if it's in your price range. For over a c note,there is a 15 inch with a cast frame that is ideal for transmission line baffles in the same company web site. Ray Hughes

Default The 15 inch

MCM Audio Select 15'' Die Cast Professional Woofer - 400W RMS 8ohm | 55-1880 (551880) | MCM Audio Select
but requires a 10 cu ft transmission line box with a 9ft folded line. Ray Hughes
