The Good Wife, and I have decided to, tentatively, throw out the tube amp and Magnepans from the living room, and build a monster sound bar for the TV. The idea, has been in the back of my head since the experimental Boom Bench several years ago, out of two folded quarter wave horn speakers with Tang Band 4 inch full range speakers. This time the project is inspired by a more woodsy interior refurbishment, and my love of the 8 inch Visaton B200‘s that reside in the man-cave.
I found a pair of lightly used Wild Burro Betsy-K speakers, with Planet 10 Phase plugs for sale on Finn.no They will form the basis for the build. Now, instead of doing all the calculations and correctly dimensioning the cabinets, I am going to go the carefree and careless approach of designing something that fits under the TV and seeing what the sound is. Afterwards I will try to amend any issues by ear, with stuffing, baffles, notch filters and similar. Imaging will be bad, bass response is not expected to shake the house. but for uncritical family listening, I think my cohabitants will be pleased. So without further to-do, here is the design:
Dimensions are 110cm long by 25cm high by 40 cm deep. What will be inside this box, you ask, TAO?
A chip-amp, possibly with Bluetooth for family members smartphones. Maybe some kind of ported, stuffed, single volume. The volume will not be large enough to make two individual back loaded speaker cabinets in one, I think. Bass will be strengthened by the placement close to the floor, and somewhat in a corner. As far as I have read Betsy’s are a bit bright, and many posters on forums compensate by playing them of axis. So maybe the low position will help a bit in that department. The proof of the pudding is in the listening. But first, shopping and chopping 🙂
