I just thought I would give a short review and say my thanks. I want to clarify that I am not a Home Theater guru or an Room Correction guru or have a perfect listening space. However I don't think it takes any of the above to appreciate the CLARITY, output and dispersion of this design, not to mention the form factor, cost to build and constructability. I currently have Klipsch Forte ii's and I have had Klipsch RF7 ii's both in this space. If you need a cabinet 80hz cabinet the TLAH is a no brainer, it isn't even close, not even remotely close to my previous setups. Not exactly an apples to apples comparison but I have Klipschorns in a different room so I believe I have some credentials on benchmark sound. It just leaves me shaking my head wondering why there are not more designs like it. As with EVERY BFM cabinet I have built, I am more than pleased with the result.
Thanks Again Mr. Fitzmaurice.
