TC Sounds Epic 8" DVC Subwoofer is rated 3.5833 out of 5 by 12.
Rated 1 out of 5 by from beefy looking subI bought four of these subwoofers, one didn't work straight out of the box, so I sent it back. then of the other three, one is still working after a week. Not impressed with this product. TC sounds needs to investigate the glue they use to assemble their woofers

Rated 5 out of 5 by from great 8great 8" woofer had for about 6 months now and play it hard, powering itbridged 1 ohm on a us amps 50hc and if you know this amp it can produce way over 500 watts at 1 ohm at 14.5 volts. have it under rear seat in a .75 cu ported enclosure with a 2.5" square port 14" long. 20 hz or lower not a problem. sound quality isn't as good as the alpine r8 I replaced it with but I fried 2 alpines in 6 months and this epic is still knocking. everyone thinks I have 1 12 or 2 10s when I tell them 1 8 I have to show them. lol and I say its quality not quantity. I should know I used to own a car stereo shop with ex brother in law and built systems over 155 db with 1 15" super woofer and and 152 db with 16 10" woofers. in either case less was more! the epic8 is the best bang for your buck.

Rated 4 out of 5 by from small sizethought I would stick this in a small cabinet get great bass ? not so! tried smaller and bigger cu vol. no luck? meanwhile I had 15" woofer realistic clone I bought from pratsexp. I blew it up! sounded great until then. So setting on couch one day I thought why not 15" passive radiator with 8" supper woofer . I cut off the voice coil on the 15" woffer put it in a 22x11x16 cabinet I had, and guess what great! maybe could be slightly smaller cabinet to get tighter response but still awesome

Rated 5 out of 5 by from Great little subI am very happy with my epic 8. I wanted a sub that very musical with low distortion; this sub is both. I only have around 100 watts pushing it now, and it blends in nicely with my full range speakers up front. Its a lot more than I expected from an 8" sub. Great speaker for the money.

Rated 5 out of 5 by from EXACTLY what I was looking for!I couldn't wait to leave this review! I built a new audio system for my car which consisted of a JL Audio 12W6v2-D2 in a sealed box built to JL Specs. Though the sub put out massive bass, it was always too overwhelming for my mids and highs. Yes, the JL was able to rattle my car with ultra low frequencies and yes, it felt good to get a massage while driving. But one thing was missing - that was sound quality! So I decided to nix the JL and try two of these. I took a week and built another box and finally was able to connect everything up last night and immediately, I had a gring from side to side. The bass from these two subs is TIGHT, Hard and Exact! I LOVE these subs.I built a box with .31 sealed on each side and am driving them with a JL Audio HD 600/1 mono amp.I may be reviewing these subs a too early, but the my initial experience is nothing less that wonderful!

Rated 4 out of 5 by from Fast, Quality BassI've owned this sub for a few months. I bought the TC Sounds Epic 8 because I wanted a sub for my camry that had fast, accurate bass, a low Fs, a small enclosure (i didn't want to sacrifice much trunk space) and i was willing to sacrifice SPL/efficiency to get that. This sub is exactly what i was looking for. I mounted mine in a .45 ft^3 sealed enclosure with plenty of room behind the pole piece and stuffed the sides full of insulation, wired it in parallel (1 ohm load), and am only feeding it 100W RMS. It's more than loud enough to supplement the rock/pop/jazz/eurodance i listen to without over-powering the musicality. if you want to shake your car apart, this isn't the sub for you. if you want high SQ for long car rides with less listening fatigue, this sub won't let you down.

TC Sounds Epic 8" DVC Subwoofer

Is the 8" Epic suitable in push pull configuration just like the KK808? If yes what is the idea volume and power required? If not please do recommend drivers from TC sound is suitable in push pull config. Can be 10" or 12" drivers. Thanks.

Asked by: Mike Sim
These will work in an application like that with a very small enclosure, but they will have a relatively high F3 so EQ would be necessary to help the lower frequencies. A volume of 0.6 cubic feet would be recommended for both and 1000 watts RMS at 8 ohms would give you plenty of headroom.

will this woofer work well in a .75 cu ft slot ported enclosure with .17 cu inches of port area tuned @ 35hz? 

Asked by: ParkerParker
This will work with that volume and tuning although the port will have to be almost 50" long in order to get a 35 Hz tune.

For  people who have experience with this sub, would  this sub play free air well? My car comes with a 9" but not in a box, I want to replace it and put an amp on it but I need a sub that can play free air. Please respond 

Asked by: Jimbass
This sub will work in a free air application but a bit of EQ might be required to get much below about 35 Hz, so it depends on how low you are trying to go with it. You will also want to watch excursion levels at high volumes, especially with any EQ added.

The suggested vented enclosure size is given from your bass box pro calculation, but the vent volume is not given to get to the 30hz.  What vent volume do you suggest?

Asked by: Midwestspeakerguy
Unfortunately to get to 30 Hz with this woofer in a box that small the port would have to be external, it would not be practical to fit inside the enclosure. The best way to get a solid 30 from this is to use a 2 cubic foot box with a 4" diameter, 15" long port. This will tune it to 30 Hz.

Please help

I have two acoustic research towers boxes. My question is, will these woofers work in these boxes. the towers measure outer diameter at "41 1/78" high by "9 1/2" wide "11 1/2" deep, built with "1/2" thick particle board. The boxes are built with two 8 inch woofers. Will this woofer work in these boxes times two each box? If not pleeeese recommend a subwoofer for this application. If you need anymore information about these boxes please let me know. Also I want them in a sealed enclosure. Also can you recommend ahigh quality tweeters for the ones that are in there. I have pictures and hope they can help. I trust all professionals output on this site. I love parts-express because ya'll never led me wrong. I have two epic 12s in my car based on your recommendations and wow. I have one of the best sound systems in the city in a 86 Chevrolet celebrity. I welcome all pro's on this site information. pleeese help.
Asked by: damaq01
I am very familiar with AR Towers. These great speakers are among the circa late 70's best. In that era, we didn't have source that went into sub woofer frequency range so no-one designed for a sub woofer. Instead, doubled small diameters woofers delivered very tight transient bass and moved a lot of air.I feel that this speaker installed in pairs in your AR speakers would leave a dip in the175 hertz to 500 hertz range. However you are on the right track with a quality 8" speaker. I have provided a couple below but PE has some great speakers to choose from.If I had a pair of AR Towers, I would do some box designing and add a low pass to the crossover set-up. Then a good 8" woofer and a sub in an issolated vented bottom of the tower. Then a good equilizer to totally shape the sound and enjoy.
