I am looking to get a single or a pair of 10" subs that can give some great spl. I already have a single 10w7 so i could buy another. They will be going in a 5-7 ft^3 box. My spending limit is a single 9515 so like $600. Thanks for the help
I can't help you in the 10" range, but be aware that for SPL you will be limited! The cone area is signifigantly less (~20% less), meaning that you would need 20% more excursion capabilities for a given ten to displace as much air as a given 12". It's handicapping, in terms of SPL, for sure... There's no replacement for displacement! (particularly in the light of "any SPL-enclosure tricks you can do for small cone subs, you can do for large cone subs!" ) But, our 12" XBL2-based 27.3mm Xmax (longer Xsus) 1600 watt RMS subs are going on pre-order next week... 12" sub will only be $300! Which means you could get two of these "super-subs" for your $600 budget... And you couldn't hope of getting as loud as these subs with any 10" out there, I am confident to say.
Thanks for the info. Yeah i know that i am limiting my self with tens but i am not looking for amazing spl numbers but amazing spl numbers with a 10". I just want to see what i can do with them. Is that 1way or peak to peak xmax? Would i be better off going two 10w7 or 1 9510 (maybe 2 if i can get them direct). I am just worried about killing my w7 i already have? Thanks again!!!
Our sub falls in somewhere between the W7 and the Brahma. And sorry for my exclusion... I always state Xmax as one-way. I think a good cost-analysis is in order here... What can you get, SPL and SQ wise, for your budget, which you have established. As far as the DD sub goes, in comparison to the BEtterAudio 12", the W7 10", and say, the Brahma 12", it's kind of like that Sesame Street skit they used to do... "Which of these things is not like the other, come along and play our game..." The other three subs are high capacity, high-SPL sound quality subs.
I am not looking for any kind of sq. I am going to put a wall in the car for the summer and see what i can hit. I am just doing this cause i will not have enough money to finish the front stage but i would still like to do something fun!!!
ok guys, lets give advice on his topic... Geo has already asked him why he wants to do a 10, his response "just because" so if he wants to try to make a 10in SPL install LET HIM As far as the Xmax, etc It will not matter in a Ported install, which will HAVE to be dot for any kind of SPL out of a 10in You SPL will ALWAYS be VERY limited, "THERE IS NO REPLACEMENT FOR DISPLACEMENT" But the 10W7 is probally your Best Bet
The 10W7 would probably be the best sounding sub out of the two, but if he doesn't care about SQ, then why not save some cash (i think) and go with the 9510. Nathan Munson hit 170 with one of those i think...i'm not sure what size sub it was.
I want tens to just see what i can hit. I am not looking for extravagent #s just really high with some 10" subs. How would the 9510 be cheaper then the w7. I already have one w7 and would just get another one for a total of 2 w7s. Do you think 7-8 cubes is too much for those setups? Thanks again.
Ah, i assumed you were looking for a single sub setup. Since you do already have the 10w7, i'd just get another one. That would be one sweet SQL setup honestly. In 7-8 cu ft, its hard to say how they'd react. Its obviously too big, but it would utilize your power much better. Theoretically it would be louder, but would the size of the box reduce the power handling to the point where you could possibly damage the subs??? I think it all depends how much power you feed them on a daily basis. You wouldn't need much power at all to get those things moving in an enclosure that big.
I already have the ten in 3.2 cubes so i do not think that an extra .3-.8 is that much more? Also tuned to 66 hz in 4 cubes gives me less excursion at tuning then with 3.2 tuned to 22 hz. I am still afraid of damaging it. I wouldnt want to be without two $400 dollar subs.
66hz is awfully high for a tuning frequency. 22hz is more of a SQ application though for a ported box. Somewhere around 35-45hz would probably be best for SPL (at least that's what all those bassheads seem to have theirs at ). Like i said before, you oughta see how much the power handling decreases in the size box you're planning to put it in before you do anything. A box that large certainly isn't recommended for that size sub.
evo- Just adding another 10W7 really seems like a good option. Tuning to 66hz is way too high. It may make a nice ~14dB peak at ~70 hz, but that is too high to take advantage of most cars' transfer functions. I would recommend somewhere between 38 and 45 hz tuning. If you did seperate chambers of 3.5 ft^3 each tuned to 38 hz, you would get a ~8.5 dB peak at ~40 hz. If you did 40 sq. in. of port area (4"x10", etc), it would need to be 16" long. The same size box tuned to 45 hz would give you a ~10.5 dB peak at ~48 hz. A 4"x10"x10" long slot port would get the 45 hz tuning. Give ~1000 watts to each driver and I think they should make some noise. B)
I agree completely! The argument for the 9510 making more SPL is really unfounded... In Nate Munson's car, he could take a Thump 10" over 160 dB. It's not in the equipment in his case, it's definitely in the install.. You WON'T find a more "extreme" car for SPL, seriously. The W7 is absolutely the best option for sound quality, it offers monsterously more excursion capability than the 95 series DD subs, and let's not even GET into efficiency... W7 hands down, IMO.
I was also thinking that another 10w7 would be great too. Why is 66 hz too high? It is not going in my trunk but on my back seat in a wall. Wouldnt that change the transfer function of the car? is there a way of figuring out the trasfer function without experimenting but measureing?
66 just seems to high... most people tune around 45-50Hz for radical SPL systems. You can measure transfer function... it's probably safe to assume that with a wall in your car your transfer function is going to begin way over 40Hz. If you can locate a speaker that will play sweeps flat from say, 40Hz up to 200Hz or so... You can stick that speaker in your car, and measure the response inside your car. The point there is a big peak, is your car's "resonant frequency" if you will...
