I'm interested in building speaker cabinets using the Mark Audio Alpair 12P driver. Maybe the transmission line similar to the Mark Audio Alpair 7 you...
I haven't played with the A12P yet. I'm working on the A10.2. The A12P will not go into a TL anywhere near as small as the A7.3. A A12P TL will be a...
I would be interested in a A12p optimized flat pack cabinets. Either BR or TL floor-stander. Let me know when you have some time to look into it. Robert...
Robert, I'm about to go on holiday and will not get much more done before I leave. I can probably whip out a Modeled strawman in a couple of days and let you...
Robert, Don't know how this message slipped through the cracks, but it did. I guess thAt I will have to get a pair of A12P's and do some playing. I have a...
Bob, I have a pair of A12P's driver's breaking in right now. Just need some cabinets for them. I would be interested in what you come up with as an optimal...
... Bob, I also would be interested in an optimal design for the A12P's. These will be my next build to use with my low power SE tube amp. Thanks Daryl...
I have finished the modeling part of designs for a BR and a MLTL for the A12P. I won't be able to do test boxes for a while, but I would like to offer the...
Bob, As I mentioned, I'm finally trying to finish up a pair of FT-1600 MkII I started ages ago. I'm to the veneering stage and have a couple of questions: 1)...
Merle, ... There are versions of PVA glue specifically made for iron-on veneer. Titebond has one and there are others. unless you live in a megapolis, you may...
Bob, A posting elsewhere (that I can't find at the moment) regarding the same technique for gluing veneer that you propose, has a chart that indicates that the...
Merle, Second thing first: I apply one coat to the veneer and two coats to the box. I sand the box with 80-100 grit prior to the glue and nothing between...
Ha! Seven years old. That's a good sign. I appreciate the clarification of what you do between coats, too. So far, my veneering effort has gone well. I...
Well, did end up with a few bubbles. Couldn't figure out why and finally realized that the bottom of my iron was cupped up in the middle such that it touched...
Bob, Realizing any effects would probably be very minor, are there any critical characteristics of the baffle? Like: can the surface have a texture? do the...
Merle, The surface texture of the baffle is irrelevant. You will read any number of posts that tell of the wonderful effects of various treatments. All are...
Merle, Two thinks: You should work from one edge/corner and then across the surface so that air is not trapped but is pushed out the open end. Also, you may...
I'm pretty confident the glue was spread evenly. Little foam roller does a nice job. My logic for ironing was to start in the middle of one end and work to the...
I have completed testing of the M12-A12 and am pleased with the results. The demo model is in the shop acquiring a oiled black walnut finish and will debut at...
Mr. Brines, A LONG time ago, you and I had corresponded about an MLTL design utilizing the 40-1354 Radio Shack speakers. I had built them and was very happy...
T.C., ... Gee, that too bad. Maybe Santa Claus will bring you a real computer! Kidding aside, the reason the PC has such a lock on the business market is that...
... Bob, ... Heh....yeah, I get that a lot. What I don't get is problems with viruses/anti-viruses, plug anything (printer/camera/iPod) in and it just works....
Following a long hiatus, I am now back to finishing my LT-2000's (plywood, mostly baltic birch). They are still open on one side making the inside fully...
