Ok. Almost done with my 12" and dual PR project. link enclosed with some pics. I am now looking for suggestions for a mid priced 15" driver for a ported hometheater setup which i would like to startup on in the next couple weeks. When I say mid priced I am looking $400 and under. Not sure what amp I would be going with as it would be dependent on the sub itself. I've been through the forums many times and seen many of the same questions out there but I guess it can't hurt to get any updated suggestions. I don't believe I will with PR's on the project I think I will go with a standard flared type port. Box footprint I would like to be no larger than 25 x 22. Height not so concerned about. So I hope the footprint helps with suggestions for possible driver selection. 8 cubic foot on high side but as always if something calls for a little larger I am ok but would like to stay on the low side. The enclosed link of the current sub I am working I decided it will be used as a midbass driver. Funny thing is that it's not even fully completed and decided to move on to something else for the low end. Tuning on the 15 " I would like to keep low. Thinking at least 15hz. I really appreciate any and all suggestions. If you have already modeled some items please include what you can
The bigger brother being the rss460ho? Have you run them or heard them. Spec on the Xmax for that is 12.75mm. The 390 is showing a spec of 12mm. Would like to stay with single versus dual. Another note I would like to see which driver could also get me to 117+ db. With staying in the driver budget. 117db is just an arbitrary number. Current sub in use not the one in progress i i have measured at 112db from listening position and just want something more. The db output is on the high end as it gets there around 60hz. Would like to move that down a lot more.
A bunch of good info there. A question when looking at older posts in the forum on drivers I saw a few using the fi SSD and Q lines. Any reason people moved away from those as i didnt see anything recent on those. Pricing doesn't seem to bad. Also came across a sight called PSI who does some subs. Here of any luck with those. Also as far as the new I see a few trying out the new Dayton um 15. What's the word been so far with those.
some say it doesn't matter for subs, others say you can fix it with a little eq, but the fi drivers don't have as good of inductance management as some of the other offerings. and to be honest, i'm not sure if there menu of features is a little intimidating to most buyers.
stereo integrity (si) ht18's are popular right now. driver tested by ricci also. very similar performance to the dayton. better price.
not really sure how to compare the 15um to the 18ho since we don't know if the xmax is 19 or something else like 28 and that could change an opinion. weak motor means largish enclosure for low q, but it appears to have really good inductance control. you could almost use the thing as a midrange driver :-0.
Gotcha there on the Dayton UM. Already going to use current sub project for something like a midbass driver and with the data not really assembled yet for the UM's overall performance i think i'll shy away from that at this time. Let me ask the question in another way. You have a ton more experience on this topic then I do so if you had around 400 to spend on a driver what would you purchase for strictly HT.
for a single driver around 400 for a ported 8 cubic foot enclosure tuned to 15hz (its got plenty of excursion for an even low tune if you like), the uxl18 would probably be on the short list. a little over budget, but they have been out of stock for a while and are apparently take pre-orders right now for the next shipment in. not sure if the pre-orders get a discount or not. iirc, they are available with a plain dustcap on request.
I would go with duel Dayton UM15's and call it a day. The UXL would be a beast of a sub, but you would have to be willing to wait for who knows how long, The Dayton HO18 is slightly better than the UM15 above 40hz, but below, from what I have been told, is not much different?
has anyone modeled the UM15's up in a ported design yet. If so attach what you have come up with. I will take a look tonight on both the rss15" and UM15". Heck if i get a little time at lunch i could probably do that here at the office as i have loaded winisd here. What kind of power would you have to throw at each. Am i talking 1000w each driver or would 500w each be good. want to know if some have modeled for their own projects yet on the UM 15 and if anyone has built the rss15".
here are three daytons all 8 cubic feet, tuned to 15hz. all with power to push driver to xmax. all hit xmax around 25hz.
1. blue - 2 x 390ho's using my guess of 16mm xmax (reduce curve by about 2db for factory spec of 12mm); 1500 watts required
2. yellow - 1 x 460ho using ricci judgment of 19mm xmax; 850 watts required
3.red - 1 x um15 using factory spec 19mm xmax; 500 watts required
i would say that any of these options would work and they increase in performance as they increase in price, so to that extent they might all be considered roughly the same bang for the buck.
the uxl18 with 2kw looks a lot like the yellow curve just 4db higher across the board.
i don't have the avalanche in my file or i would have included it for comparison.
thanks for that. I do like the look of the 460ho but do not want to go 18. The 390 doesn't model to bad. Think i could make some adjustments to the curve with a little playing around on the box size and eq. Still stuck on the single driver though. The highest powered amp i have right now is a 1000w so i also have to take that into consideration. I could pop for a new one but am a little reluctant on that. let me take a look at a few things and model up something.
