  • 3rd build; preliminary prints. Overnight Sensations

    Well,
    It's time to build anothern. I've been wanting to put together some killer pc speakers for the office, and Paul's Overnight Sensations appear they will fit the bill. I'm in no hurry to finish, so I will be putting some extra finesse into the enclosures. Similar to the curved tritrix, but hopefully much, much easier to jig up and laminate at only 12-3/4" tall. Also plan to fully integrate the Dayton DTS-1 amplifier. So here goes..

    Holy Cow! That's really going the extra mile on the cabinets. You also win an award for making a super-compact crossover.

    I just cut crossover boards for mine tonight but decided to split mine into two parts (tweeter, woofer) to fit into the tiny cabinet. I wish I could have seen this before I started cutting.

        Paul will be proud!

        Do you mean the t-amp?

          Yes. In case it's not enough juice, I'm going to bring both of the amp channels out of the powered side, so I can run on an external amplifier if I want to. For the now though, and for the office, I'm sure that little Tri path will be more than enough.

            Did you consider using a slightly wider and longer port, to push its entrance past the driver's magnet? The larger port should also help to disperse any reflections from the back wall .

              It does not have a pole-vent, detriment mitigated.

                Outstanding! I've been secretly hoping someone would do one of my designs in a curved cabinet someday. I'm excited to see how it turns out!

                That riser is just the thing to get the most out of this design. These things oughtta sing for you at your desk!

                Also, I'm with Wolf, I think that because the pole piece isn't vented, I don't think the port location will be much of a problem. On the other hand, you can use a 1.5" dia PVC pipe that is 7.5" long to get the same tuning (just checked it in Unibox). Not sure if that helps.
                Isn't it about time we started answering rhetorical questions?

                  These look like they are going to be real lookers when you're done!

                  Would the port venting into the partially-confined space between the bottom of the cabinet and the integrated base change the effective tuning?

                    I doubt it; I think I would be more concerned if this were a larger system pushing higher port velocities. As it is, there is still at least a full port diameter between the exit and pedestal foot.

                    Paul, I had that thought last night; going with 1.5", but with space quickly becoming a premium in these tiny cabs, I don't think there's much to gain, and again, the lack of displacement doesn't really warrant a big concern.

                    I'm gonna see if I can't do you some justice on these things!

                      Nice Drawings!! I draft all my stuff out to in 3D CAD but no way I can make them as presentable as yours, good job. I like the design too, I think I might have to borrow your blueprints if you don't mind.

                      BTW Paul since you're in this thread I have a question or two for you. I was planning to use these for computer speakers. Problem is is that I use a triple display, a 26" with 20.5"ers on either side so my whole display is ~56" wide. I was going to place these right up beside the outer monitors, baffles ~level with the screen but they'll be wide open on the far side. What will that do to the BSC? Also what would you place the limits for being off axis (horizontaly) before FR suffers?

                      Thanks.
