one dayton ho 18 or two dayton hf 15s ? - Page 2

I think the difference between the two options is close enough that you can just go with whichever you feel more comfortable with.

Thats the problem, still not sure. You have me sold on doing as a DIY but I'm still figuring which size is best. 4 Infinity would be a little less than 2 of the Dayton 15's but then I have to build 4 boxes vs 2.

no because you can just build two dual-opposed boxes for the infinity.

If you go with the 1262W you can put two drivers in a single box, and wire them together for a 4 ohm load. You could put both of them in a 3 ft3 box. Ported will get you better bang for your buck, 6 ft3 would be needed for a pair of drivers per box.

You're looking at something like 15" x 26" x 18" for 3 ft3. Or 19" x 30" x 24" for 6 ft3



Above is with 650 watts. You can see the ported is significantly stronger from 50hz - 20hz, the range that makes you hold on to your seat when something big goes boom... You can look at building your own subs in many different ways, but you can design them to fit your needs, and maximize your system. For example, the larger boxes could simply be built as "end tables", with some kind of nice counter top material on top, tell your wife feel free to decorate wink.gif

(this is just an example of a similar design)


Anyways, starting your own thread over here might be a good idea, we're kind of jacking this one.

hey I don't mind I found this to be interesting by the way I forgot I had all 6 of my jbls only turned half way up I set the gain at 80% and now hitting hard just not low enough I think. so if you diy in good boxes should be better and loud. cant wait till I can add the two 15s to my other subs should be over the top for cheap as most of my jbl250pbk powered subs I bought for $104 each(open box returns) with free shipping to Hawaii.

8 ft3 tuned to 18hz using a pair of 4" x 23" ports, with a 18 hz high pass filter engaged looks like the best set of compromises to me, assuming that amp puts out 600 watts per channel at 4 ohm. If it's closer to 450 watts, things look even better (with only 1.3 db less then 600 watts).
so response only down to 18hz is that pretty good like I will not be missing out on too much sub sonic ht stuff as I have never been around a good sub in ht.do I need to dig a little deeper or is 18hz really good enough and to go deeper not that big of a deal? been reading minidsp manual online wow nice. I got to have one

If it were me, I would definitely go with the two Dayton 15's over the Infinity 1262w's, mainly for the lower extension that tte Dayton's offer. I just can not see the Infinitys going down below 20hz. I would build some large/single/ported enclosures for the Dayton's and never look back. You can always add more sometime down the road.

http://us.infinitysystems.com/tl_files/catalog//Infinity/Infinity-Car/Specsheets/Reference/Reference/1260w/REF1260W_PI_EN.pdf

The specs on the infinty show it should be an efficient sub and for my listening, it will be primarily music with some HT so super low freq response isn't needed. I doubt any of the metal, classic rock or Willie Nelson I listen to will be in the 10hz range. The 1260/62 shows a range of 23-400hz in a sealed 1.25-ft3 box. 1.25 is pretty small and thats the option I like about the infinity line. I don't want a 12, 20= ft3 box just because of size constrants. 20 years ago I may have been ok w/ it but the wife wouldn't dig it. Even using a ported box like Jay spec'd up is small enough to do 2 pairs and visually I could make it work due to the smaller size.

Yeah, my bad I really didn't mean to but I'm glad my stupid questions have helped. I'm so green with this stuff smile.gif

I have liked the bass sound of jbl's but I found them to be pricey when I tried to purchase. @ 104 each free shipping isn't bad. Hell any free shipping to Hawaii is awesome. I wonder if there is a way to improve the box you're using to get the sound you desire w/o having to spend more $.

Yes 18hz really is "good enough" dont let all the crazies around here make you think you need 115db at 10hz to play ball. If your budget was a lot higher then sure just building eight 18" subs would make the most sense, but it's not. Maximizing the capabilities of what you will have is what we're going to do with an 18hz ported sub.

^ Precisely. I am extremely confident you'll be overjoyed with your results. smile.gif

As far as the box, you can plan it out exactly here

http://www.hometheatershack.com/forums/enclosure-volume-calculator/

A 22" x 30" x 28" box from 3/4" material with a pair of 4" x 23" ports gets you a little over 8.5 ft3, so that's a good starting place. The miniDSP is a very good choice, it will also let you EQ the in room response.

Guys, he already has the epx2800 wink.gif
Jay I tried two different winsid programs for a few hours and got no where on how to use it very well. as I will not need this program again for a few years I do not feel the need to learn it. I will just take your word for it and build 2 boxes at 8.5 ft3 so as to allow for ports and bracing with 2 ports 4" x 23"They still have not shipped my speakers yet maybe their waiting for me to contact them so they can state a shipping price to Hawaii I hope not.

I'd opt for the dual HF 12" subs... The HF has a more extended LF response. I have both a HF 12" sub and a HO 15" sub built in optimal sized sealed boxes... The good thing about the HO drivers is that it can be designed in a smaller cabinet than the HF... In fact, the HF 12" is in a 18x18x19 box and my HO 15" is in a 18" cube.

But the 12" HF sub has a F3 of about 40Hz and the 15" HO sub has a F3 of 55Hz. While the 15" definitely can displace more air (you feel it more), the 12" goes down lower. If i had to do this again, i would have gone with dual 12" HF subs. More so since the HO sub requires a lot more power than the HF.

(I swear I posted this earlier in this thread but can't seem to find it....)

This thread has been about the HF 15 vs the HO 18... The 15 is only $23 more then the 12", goes deeper and louder. Requires a bigger box of course.

Honestly not that surprising, I have to deal with the same kind of BS living in AK. All is not lost.

http://www.amazon.com/gp/product/B001UJGUQS/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER



Same box size and power level as the planned HF build. The JBL is rated 14.5 mm xmax, pretty good deal for $117.
post #48 of 65

Another is the Infinity 1262w, run two of them in a 8cu ft enclosure.

http://www.amazon.com/Infinity-Reference-1262w-1200-Watt-High-Performance/dp/B0028AYIXK

 

Both in the same enclosure and tune but using a single Dayton 15HF with 300w. While the Infinity 1262w is running TWO drivers and 500w

the Dayton f3 is 18hz where as the jbl is 25hz but yet both give the same results and use same box. I don't understand specs at all it seems. might have to trust you guys and go the jbl route 15s or infinity 12s. at least you can drive somewhere(maybe long drive) Jay but at least I have snow only on the mountain. yes it always states except for AK and HI

would I be better using the single voice coil version?If I used the dvc not sure of how to wire as I would use two speakers on each of my two channels

I knew that... just got a bit off subject... It's just that I meant that the HF driver is better than the HO if you want lower bass response..

If you are building a single driver sub, then get the SVC... If you are going with two drivers in the same box, get the DVC... You can wire them in series as two 2-ohm coils or in parallel as two 8-ohms coils for a end result of 4-ohms... maximizing amp efficiency.

amazon was out of stock said ships in 1 -3 months but they did have a used warehouse deals for $87 so I bought that one still waiting to here back about the ebay seller and shipping prices may end up with the daytons also

checked amazon again they had one and only one gto 15 in stock this to go with the used one from amazon now I will have my two subs regardless of what ever happens with the daytons from ebay cant get any response from the seller about the shipping price I sent him a message as to just go ahead and cancel the order and refund my money since in six days he is slow it been three days of sending messages with no response if the seller replies with a good shipping price than I will go ahead with the Dayton order for a total of 4 15 inch subs added to the 6 12's I have I will need to buy another amp and then maybe a new wife na I will have to just store a pair of subs for future use as I would like to keep my wife.the thing that gets me about the gto's they rate them at 1400 watts peak but only 350 rms so does this mean I could run say 500 rms for HT for a 2 hour movie and also 500 watts for bass heavy music for like and hour at a time then letting them chill or what?

They rate it like that because it's marketed for car audio. As long as you aren't running continuous max power sine waves you dont have anything to worry about. Dont even take the power handling into consideration.

got you for HT not a problem but I do sometimes run it near max I think with dubstep ,bassnecter etc just for kicks for an hour or so for thrills.so for everything else it will be ok thanks worse comes to worse the jbls are priced good and to trash one would not be overly tragic not enough to cry about. jay I remember it was you that answered my first diy post and suggested building statements I built the center and love it thanks for all your responses.

decided on box shape for 8 ft3 box w= 23.5 h=32 d=23.5 this is 8.54 ft3 the extra .54 is for driver, bracing, and ports
this allows for most efficient use of a 4x8 sheet 1 sheet needed for the box. extra wood needed for bracing I have not decided on bracing yet.
I will use red oak plywood from home depot and use red oak stain with polyurethane for finish.
total price for each box jbl gto15 for driver , red oak plywood, Dayton binding post,etc $200 for 8ft3 passive sub woofer
I will build two later when I have time still need to buy the 2x4 minidsp balanced
should I use double thickness for the front baffle? I am going with single unless that's not good
post #60 of 65
So you decided to go with the JBL over the Dayton because of cheaper shipping to HI?
