Rated 5 out of 5 by from Great drop in replacementSo far this driver is a great replacement for the junk that came in a Cerwin Vega HTIB sub I bought for $20. Without any other tweaks to the enclosure this sub is far better at everything, much lower response, tighter transitions and overall well matched with my 5.25" desktop speakers. For a total investment of $95 it can't be beat.If you're looking for huge low end or lots of SPL, you're going to have to put in more effort than I felt like, but I can believe its very possible.Check the image to see the driver versus what comes in a cheap sub.

Rated 4 out of 5 by from For Car Audio Buy this right now!I was apprehensive about purchasing tang band for my car but did it after reading the positive reviews. All I can say is, this woofer is unbelievable! I custom built a .6 cu/ft fiberglass enclosure for my 2010 Silverado. I have a 2" port 7.5" inches long tuned to 40hz. When I listen to anything with a kick drum it's like someone is hitting you in the chest with a hammer. I still can't beleive this dinky sub can evoke that response. Trust me this is a good buy. I have been in car audio for 20 years.

Rated 4 out of 5 by from Great drop in replacement for SUB 80HTUsed this as a replacement for the woofer in the inexpensive Dayton SUB-80HT powered sub. The 80HT is a good starting point, but at that price point, the woofer out of it isn't anything fancy. The 80HT according to my win ISD measurements is tuned to 41hz and is about .76 cu ft, and has two 1.875" diameter ports 10" long.As a drop in replacement the Tang Band 740P provides a nice +3db bump in output around 45hz due to slight mis-match of the port frequency of the box. Win ISD wants the ports to be a bit longer which looks impossible from a physical standpoint.Sound is impressive relative to the 80HTs stock woofer. It goes substantially lower, doesn't bottom out nearly as easy, and unexpectedly has more detail and is more musical to the ear. Definition on string bass is nice. Drums and dynamics have a nice kick, without being boomy. You don't get more overall output because the sensitivity is similar, but you do get more bottom end and it sounds louder in the 25-50hz region.For well under $200 total, the sub sounds night and day better, and is well worth the upgrade.The SUB-80 has an 80w amp and it seems the Dayton 240w plate amp may be a good match, as the amp seems to give up before this woofer does. That may be my next upgrade.Great woofer.

Rated 5 out of 5 by from Absolutely StunningI talked a customer into 4 of these in a Chevy 1500 extended cab. Built the box for 2 of them on the drivers side, (was going to do the pass side over the weekend so he had some bass with half the install done) hooked a small amp to the 2, he does not want the other 2. He had a single pioneer 10" but didn't like how it stuck out from under the rear seat, so thats why he was going with the 8's. The origional design was 1000WRMS to the 4 subs. now he has that amp 8 ohms mono on 2 of these and is hitting 140.3 db... NO B.S. the amp is doing right at 600 WRMS at the 8 ohm load and is absolutely slamming... has a -3db point of 34 hz in the truck, and all that is done is roll on bedliner for sound deadening to achieve this SPL.. this was done 2 weeks ago & since then I have sold 6 more to be installed this weekend and next week for 3 more customers. Put these subs in a .8' box with a 3" x 9" port or a .6' box wih a 2"x6" port or a .5' sealed and put 200Watts to them and you will NEVER be disappointed. I WILL be using more of these, and wish they made 10",12", and 15" in this line.

Rated 4 out of 5 by from good for 50hz and upFor home theater, it is not enough for 40hz and down. I've heard smaller woofer producing much deeper bass with a much higher price tag. But as a sub-woofer, from 50hz and up, very few, regardless of price, can sound better in terms of speed and resolution. For music, this is where this woofer really shines!! Small full range drivers match very well with this woofer. Light speed indeed! Deep earth shaking bass for home theater, it is not.

Rated 5 out of 5 by from ALMOST PERFECT!i was looking for a car sub to go into my 99 civic coupe. im extremely picky about the quality of my bass in tone and speed. so after plotting out tons of different enclosure ideas i came across the perfect match for simplicity and pure bass quality. this insane 8" sub and the peerless P830468 XLS 10" Passive Radiator, 265 gram version. the enclosure was the Goldwood TR10S 10" Single Sealed Box found here on PE. the bass i get in car drops well into the 20's and is so tight and punchy. what is so amazing is how effortlessly this combo reproduces the ultra low frequencies with so much accuracy. this is by far the best sounding car sub ive ever heard. this is not an spl setup but for pure sound quality that still gets louder than needed in car. out of all the subs ive owned this on will be a keeper. ive spent tons of money on subs and bass trying to find the perfect setup and never had what this crazy sub can do for ultra deep pure bass. with this setup the sub is tuned to @29Hz and has a -3db a @30Hz OUT OF CAR! i dare ou to assemble this perfect gem. 100 watts rms is more than sufficient from an amplifier.

Box size for 12 inch dayton passive radiator

I want to buy 2 of these and put them with 2 dayton 12 inch passive radiators (the cheap ones on this site). How big should each chamber for each sub be? Im using it in my grand marquis so its for music not movies. I want it to be somewhat musical too. Someone said they used .6 cubic ft but im still not sure
Asked by: kerry789
Passive radiator boxes, regrettably, are not suitable for auto use...That is, it would work, but not anywhere near as intended. PR's are entirely passive, that means they have no control. Essentially a large weighted mass suspended on the side of your box.The G-forces of regular driving would affect the PR massively and the PR in turn would affect the driver massively. Best case scenario, the system is off when you round a bend or stop suddenly and the hundred ounce or so PR cone reaches its maximum physical limit and rips itself to pieces. That would completely bottom out the sub woofer and might even damage it.Now imagine all that cone area and weight of the PR pushing IN all the way...two of these in tiny little boxes, 0.2 cubes each, (no really, just a little bigger than what will physically hold the driver!) with 100/150W each and crossed over no higher than 100Hz will be surprisingly punchy. After you factor in cabin gain a simple setup like this wouldn't even need porting, even though the driver seems to be made for it.

sonosub with this driver

Hi, I have a Bash 300 sub ampli and one of those sub, would a .9cuf volume ported with a 3"by8" be a good solution?
Asked by: airliner1
This would work out pretty well as long as the enclosure is heavily stuffed. If you can get away with a slightly longer port, something like 12-14" it would be perfect.

Box tuning situation

My van is limited to a 10" x 42" x 21" box size under the back seat, or about 3.88cf. Would 4 Dayton RSS210HO-8's be more appropriate, or 2 of these? My amp puts out 300 watts at 2 ohms and I am looking for maximum performance given these limitations. I have run a Dayton RSS390HO facing up in this box sealed and am now running 4 RS270-8's in this box tuned to 28hz and both had seemingly no low bass and extremely muddy upper bass. I also ran 6 x 6" buyout speakers (12ohms each, 2ohms total) facing forward in this box sealed and the sound was much deeper, cleaner, and louder until the voice coils fried. 8" is the biggest I can fit if I face the drivers forward. I listen to a lot of metal and need a fast clean kick.
Asked by: 11Bravo
Of the two options, four RSS210HO-8 woofers would be the best in that volume. If you built the external dimensions of the enclosure to what you specify with two 4" diameter ports that are 15" long each, you will have a tuning frequency of 29 Hz and a very smooth response.

I would like to know if these three item will work together to make a very good sub for music. I plan to use a pair of them with book shelf speakers.

Asked by: guyadiio
yep, should work.box is a little big so when you are integrating it with your mains, start conservatively.The Qts of the driver is pretty low, so it should be in a ported box though.Add a pair of 8" PRs to the sides of the box to get the most out of this setup.
