how many watts can the SA 8 take for daily

If you decide on the truebass 8's and need any pointers, feel free to PM me I'd be glad to help. I'm sad that a car payment made me sell mine //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

get dd or sundown 8's i have 2 dd 1508's running 1000 rms to each sub from a dd m3 and it pounds

ya im gonna just end up buying a 1508 a true bass and a sa8 and test them all out and see which i like best

you guys think an SA8 could handle 600 for daily? or 750?

If ya run an SA8, better have at least that much power, lol. their spl'n them at 3000+ per, lol. Super stiff suspension, crazy high Qts. TSP's from the SA 8 that was brought to me for testing

SA 8 D4 TSP's (in series)

Re = 6.2144 ohms

Fs = 55.0564 Hz

Zmax = 71.3945 ohms

Qes = 0.8103

Qms = 8.4987

Qts = 0.7398

Le = 4.5791 mH (at 1 kHz)

Diam = 158.7500 mm ( 6.2500 in )

Sd = .0198m^2( 30.6796 in^2)

Vas = 3.0363 L ( 0.1072 ft^3)

BL = 20.1586 N/A

Mms = 153.1704 g

Cms = 54.5569 uM/N

Kms = 18329.4824 N/M

Rms = 6.2346 R mechanical

Efficiency = 0.0588 %

Sensitivity = 79.7088 dB @1W/1m

Xmax = 13mm

as you can see it's one of the least efficient subs out right now, becoming known for the pole plug hitting the inverted dust cap during high excursions, but with their suspension that requires alot of power. Rated for 600 daily, as stiff as it is I'm sure thats more of a thermal rating than a mechanical rating.

Here a freq plot showing output, both are in .8 net, the SA prefers 30Hz for flatter response thanks to that crazy Qts, the TB likes 32Hz. Both subs shown with 600 watts applied. ~4.4dB difference @ 34Hz - 37Hz .8 @ 30Hz and ~2dB @ 50Hz.

its ok if it wont get that loud its going right behind my head...im not lookin for numbers haha i dont want anything over 140 for spl....always been an sql man....i miss my oz me's //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

lol, be lucky to do a 133 with either on 600 in, The Graph was basically showing sound characteristics. The SA deviated alot more, heres a gain plot showing transfer function. The High Qts is very apparent in the subs "boomy" characteristics. The TB contours more naturally and would blend into cabin better with less eq. Since the del sol is a smaller car, you would want your natural dips in response to be around 50-60 Hz to compensate for cabin gain and make the output more flat. If I were to run an SPL system around an 8, at this time the SA-8 would def be my driver of choice. Extreme power handling and High Qts makes for a more SPL derived driver. Higher Qts subs are known for being muddy sounding, Low Qts subs are naturally more transient and natural sounding. Not saying "hey dont go with the SA-8" just saying for your goals the DD or TB would be a better choice, and the TB is the most user friendly driver of the 3, Not alot of people have played with True Bass stuff enough to know what they are capable of but names like DD and Sundown are in every bodies vocabulary. Bang for the buck wise, I guarantee there is not a comparable sub on the planet that is readily available to the car audio market. I have a definitive technologies 8 that flat destroys a TB SQ wise, but it peaks out around 128dB and thats just not enough to cut it when the windows are down and cruising at speed. I, like you, am not a numbers guy, every build I am currently working on is an SQ system and I currently don't own any "dedicated spl" subs, I just simply have no need for them at this time. I have run alot of different brands over the past 17 years, and owned over 400 drivers now, the True Bass Subs have always been a no compromise fail safe when looking for ample output and good sound quality and time after time I return to them for builds be it SPL or SQ.
