Tang Band W8-740P 8" Subwoofer
Tang Band W8-740P 8" Subwoofer is rated 4.5938 out of 5 by 64.
Rated 5 out of 5 by from You wont find a better 8" sub for this priceI put 2 of these in a modified prefabbed Dodge Ram crew cab box and they are very musical and loud. The box ended up being 0.28 cuft net per sub, with a 0.75" x 3.5" x 13" port (approx. 39 hz tuned). Not ideal enclosure but it flat works. 250 RMS per driver from an Alpine MRV-M500. I compared back-to-back in the same enclosure with 2 of my JL 8W3V3-4's and the SQ, SPL and response are nearly identical, I actually think the TB's sound slightly better, although they are brand new and my 8W3's have been hammered on pretty hard. If you are on the fence about trying these, just do it!

Rated 5 out of 5 by from Wow! This woofer sounds amazingLook guys, I've been doing this a LONG time... Used many different woofers in numerous cars... Polk Audio, Cerwin Vega, Fosgate, JL Audio, MTX, Orion... This 8" sounds amazing... Best money I've spent on a woofer yet... Super tight install in a Jeep Wrangler 2 door... .81 cu ft box, 3" port, 21" long, stuffed, but not overstuffed and it sounds incredible. Fills in the sound extremely well! Build the box right, and you will be rewarded very well...

Rated 5 out of 5 by from Best Sub for the price.I got one of these subs and I actually put it as a replacement in a bazooka BTA825D active enclosure. It hits much harder then the sub that was originally in the bazooka. Its getting about 200 watts RMS. I'm very happy with it. I know if I make a custom box for this sub to the specs of the manufacturer, then I can definitely get even more bass out of it. This sub is also good for home theater systems.

Rated 5 out of 5 by from Great performer!Bought 2 of these after reviewing some of the reviews, and am glad I did. Put 2 of these in a 1.8 cubic foot net ported enclosure. Tuned to 38hz, with a 5.5 h x 3.5 w x 20 l port, with 500 clean watts going to them, and could not be happier. (Although once I rebuild the box later, will give it more port area, these little 8's move some air!) Thinking about picking up 2 more in the future, if I can manage to squeeze all 4 into my standard cab F150.

Rated 5 out of 5 by from Solid/cleanWithout being technical, Tang Band is a solid brand that is under rated on many levels. Sound quality is perfect, not good, not great, perfect. Magnet (motor) is beefy, spider is well made, cone and surround are great. Have two of these 8in. They go deeper than 2 jl w1 10in subs in sealed box. I put one in a 4th order (sealed and ported box with sub in the middle) and put it in a 2004 F-150. Everyone is shocked at how loud, clear, and earth shaking it is! Same setup for a Honda Accord. Both have a Rockford Fosgate Rockford Fosgate Prime R500X1D 500 at 4 ohms. If you are looking for affordable, compact, and powerful, this is the best sub I have found on the market.

Rated 5 out of 5 by from Deserves a big passive radiatorThis is a superb driver as all the other reviews attest. Tremendous Xmax, can be used in very small boxes, sounds like a 10" or 12". However there is one very important thing that doesn't get mentioned much: This thing will over-drive most ports and passive radiators. A 2" diameter port is way too small and will generate turbulence, wind noise and distortion long before the driver runs out of cone travel. Even a 10" Dayton Passive Radiator is too small, this driver can overdrive it at the tuning frequency. That's right, it easily bottoms out a 10" quality PR - I did it with an NAD 2140 amp. You should really use a 12" Passive Radiator with this thing to get all the output it's capable of. And if you do that, it will truly shake the walls.

Tang Band W8-740P 8" Subwoofer

What enclosure would be the best for this driver?  Sealed, Ported, PR. I want to build it a small sealed enclosure but is there a chance that with its crazy xmax that it would make a vacuum on the surround and rip it?

Asked by: Mark Bethel
Small sealed will work well. The surrounds on this woofer are thick enough that it will not deform due to any vacuum pressures from inside the enclosure. A volume of 0.3-0.5 will work well.

Hi, Looking at the part# 300-7064, the .56 cu. ft. cabinet might also work with the w8-740P, it is closer to optimal and also cheaper. What size port or passive radiator would be acceptable with this cabinet? Thannks

Asked by: Cecil
This volume will work well but only with passive radiators. I would recommend two of the 8" Daytons with 75 grams of weight added to each, which will provide a tuning frequency of 38 Hz and and F3 of 40 Hz.

What size amp should do i need for this? Also are there any boxes for this that are recomended that i could buy?

Asked by: BrickDabkowski
Any amp that is rated for 100-200 watts RMS into 4 ohms would work well for this subwoofer. Our SA100 or the Yung SD200 would both be good options. The only enclosure we have that would work well with this woofer would be the 0.75 cubic foot knock down type below.http://www.parts-express.com/knock-down-mdf-075-cu-ft-subwoofer-cabinet-for-dayton-audio-8-reference-series-ho-subwoof--300-7075

I am building a box for a Tang Band w8-704p 6.5x9.75x27 outside measurements in inches. Int. volume .606 cf. I see that using a 3in port would need to be 20in. Is it possible to use a 2in port of shorter length or would that hurt performance?
