DavidH71 Posted January 13, 2023 Author Share Posted January 13, 2023 This is the raw unsmoothed combined response at my main listening position with the 100hz crossover enabled in the AVR I am actually surprised at how good it looks as my previous setup had some quite strong room modes which really messed with the bass , I don't think I am even going to bother with MSO as it has the slope and response I was after anyway and I am currently listening too it now and it sounds very very good , I will report back once I have put some more time into listening. 2 Link to comment Share on other sites More sharing options...

Does this have EQ applied? Not sure which AVR you have but Audyssey, ARC, Dirac etc could all probably smooth that out nicely 1 Link to comment Share on other sites More sharing options...
DavidH71 Posted January 13, 2023 Author Share Posted January 13, 2023 No , that's the raw response , my AVR does have Audyssey XT32 (Denon X3700) but I actually prefer to use MSO https://www.andyc.diy-audio-engineering.org/mso/html/index.html as in the past it has done a much better job than Audyssey XT32. But that's actually a pretty good raw response and needs very little if any tuning and at this point I'm just listening to it as it is and it sounds very good , the next problem is my house , stuff is vibrating all over the place , especially the windows in multiple rooms.

Well that's really nice, great place to work from! Here's my raw bass response with 3 subs, no EQ (other than delay on rear sub) and No smoothing here's after Audyssey calibration. No smoothing, with 80Hz LPF in place 1 Link to comment Share on other sites More sharing options...

Again, this can probably be drowned out with appropriate SPL. I'm no help at all. Edited January 14, 2023 by Janus77 1 Link to comment Share on other sites More sharing options...
DavidH71 Posted January 15, 2023 Author Share Posted January 15, 2023 (edited) After tuning with MSO , High pass 24db LR @ 11hz to protect driver below port tuning , +10db house curve and the 100hz crossover implemented in the AVR , no smoothing. It does sound better than just untuned , more even bass, very very happy with the result , movies sound very very good too. Some of the cleanest tightest bass I have ever heard , my son and daughter was over the other day and they were playing their favourite bass heavy tracks and my sons comment was it sounded similar to his car subwoofer but goes lower and is cleaner , I would have to agree with him , we both have very good subs in our cars and it is a lot lot easier to get good bass in a car so I take it as a big compliment , it put a smile on his face and mine , we all agreed they kick ass , very very good drivers and I have no hesitation in recommending them to anyone , I think Dayton Audio have done a stellar job in designing these and at a very good price too , well I did purchase them before they went up by $300 , still very good value though.

DavidH71 Posted August 15, 2023 Author Share Posted August 15, 2023 (edited) 2 - 1010 X 600mm 4 - 1010 X 580mm 4 - 896 X 564mm 4 - 896 x 466mm 4 - 764 X 60mm 2 - 686 X 564mm 4 - 580 X 564mm 2 - 520 X 564mm 4 - 520 X 60mm 16 - 466 X 176mm 2 - 258 X 176mm 4 - 210 X 78mm All above is 18mm MDF , driver cut out is 358mm and centred in the middle of the baffle. I just had a request for my cut list for this build so I thought I would add it here in case someone else needs it , it is for 2 x cabinets so for 1 x cabinet just halve the quantities. The port length I originally calculated for a 17hz tune is incorrect as the build above has the port length at 1283mm whereas the correct port length is 1200mm which means the dimension 682 X 564mm should be 603mm x 564mm for a 17hz tune , it only makes a small difference as the tune ended up around 15.6hz with a 1283mm port length and still works very very well.

DavidH71 Posted April 16 Author Share Posted April 16 Looks like Dayton Audio has dropped the 15" RSS390HE-22 driver and it's no longer available , shame as it was a very very good driver. The closest driver from Dayton Audio is the 15" MX15-22 which is still available. Link to comment Share on other sites More sharing options...
DavidH71 Posted June 17 Author Share Posted June 17 Apparently there is going to be another driver from Dayton Audio that will replace the RSS390HE-22 that was discontinued , no time frame yet. Talk is that the manufacturing costs went up too much for the RSS390HE-22 driver to continue selling it without a substantial increase in price. 1 Link to comment Share on other sites More sharing options...
Amoeba with special needs Posted June 17 Share Posted June 17 I think I may have bought the last 2 of these high excursion drivers. They were sold out everywhere I looked o/s but Wagner in Australia had 2 left. (February this year). Obviously I bought them both, such a shame they have been discontinued.. Well done on the build. 1 Link to comment Share on other sites More sharing options...
DavidH71 Posted June 17 Author Share Posted June 17 Good job on getting the last of this awesome driver. I'm pretty sure I had some of the first ones in Australia as no one here was even showing them as available anywhere and WES imported them directly from Dayton Audio for me and I only payed $495 ea delivered , not long after that they increased a lot in price , so for me they were extremely good value and nothing else out there could compare for performance vs cost. Hopefully the replacement driver is of a similar performance/cost ratio. Link to comment Share on other sites More sharing options...
DavidH71 Posted July 15 Author Share Posted July 15 https://www.daytonaudio.com/product/2065/umii15-22-ultimax-ii-15-dvc-subwoofer-2-ohm-per-coil https://www.daytonaudio.com/product/2066/umii18-22-ultimax-ii-18-dvc-subwoofer-2-ohm-per-coil Looks like these are the possible replacements for the HE drivers although more optimised for sealed enclosures but they should also work for vented , they have similar cone excursion to the HE series but the motor is not as strong , they are not available yet , pre-order from Parts Express , their prices seem pretty good though , who knows when WES Components (Australian distributor) will list them as available.
