TC Sounds Axis 15Q1 15" Quad VC Subwoofer

Unleash your music with room to spare with the Axis 15Q1 15" subwoofer. The AXIS is designed with high motor force, long excursion and very high power handling to provide loud deep bass in the mobile environment, or any environment where small enclosure size and ultra-high SPL are required. The AXIS has a 40+ pound motor, flat-wound 8-layer conductor voice coil on a triple reinforced stainless steel former; it works harder so you don't have to give up half your car to a large subwoofer box.

TC Sounds Axis 15Q1 15" Quad VC Subwoofer
TC Sounds Axis 15Q1 15" Quad VC Subwoofer is rated 4.5 out of 5 by 8.
Rated 5 out of 5 by from Tc Sounds Axis 15"I bought this woofer two months ago in a 20" cubic box with an old Crown XLS 602 power amp. I am very satisfied with it. It sounds very clean and tight even without eq

Rated 5 out of 5 by from Great productI have been in the car audio industry for 10+ years and have just started to get into home audio. I recently converted an elemental designs 13av.2 to a home audio sub in a 2.7 cu ft sealed enclosure with the dayton 1000 watt plate amp. I have never written a review for a speaker in my life. The ED 13av.2 spider tore a few weeks after i built the system which i was actually prepared for due to the history i have had with elemental designs (had the sub in storage for about 5 years and previously had to have it re-coned.) Ordered this sub and enlarged the opening to the enclosure which ended up netting about 2.5cu ft. The output, depth, accuracy and overall tonality if this speaker far surpasses the capability of any speaker i have ever heard. Doesnt get much better than this. 1000 watts dosent take this sub to its limits. In fact it can only take it to about half of its total xmax. Even then the amount of output compared to the ED is ridiculous.

Rated 5 out of 5 by from the best to dateThe best sub yet. I'm upgrading from a dayton hf 15. The dayton was very deep but not enough force, impact, x max, or spl.the axis is a sonic weapon! I have it teamed up with a 15 inch vmp and Dayton 500 watt plate amp. The vmp is a champ, tunning from about 26 down to 12 Hz! Just change the stack of weights. Axis handles thunder down to earthquake sounds. Don't let the 4 coils scare you. The owners manual gives 3 easy ohm examples. Specs seem underrated. 16 mm x max? Well technically the coil is very long and the magnetic gap may be left behind. Just listen to Mr. Stampler's video. "The axis is good for about 3 inches peak to peak excursion. It's a really serious driver. Lotta spl!"The bass is soo deep is makes you happy inside. I feel sorry for some who had bad glue-ups. If mine comes unglued, send me another top assembly. Because I haven't heard a better sub yet!

Rated 1 out of 5 by from Zero quality control, or B stock?>I just received mine today, and boy was I excited to have the best sub out there! First I open the motor and notice a bunch of gouging and discoloration on the pole piece. Not happy. This product does not look new! Ok, so perhaps they recycle the pole pieces, it should be machined smooth to look new. Alright, moving forward, I open the basket assy and notice the finish of the cone face is all bumpy like there was sand on it. The cones are painted aluminum. Very disappointed they are to cheap to anodize a product supposed to be so good. I go to push the coil slightly with my thumbs, and the entire spider assembly pops free! You have got to be kidding me! This speaker is going back so fast, I am absolutely appalled that this product cant even keep up with the quality of a 200 dollar lanzar opti. Parts Express, you better have return shipping covered on this one! And your customers deservr the chance to read this review. Im still in shock.

Rated 5 out of 5 by from Best woofer ever.If you are searching for absolute lows, with little to no distortion, and high power handling, then your search has ended. I use this sub in a sealed box in a 5.1 setup for my recording studio. Sfx hit hard, and mixing at sub frequencies (20-35hz) is MUCH quicker, as I can hear the actual tones, and not the sounds of the cone flapping. Translation to other systems and home theaters has been excellent. The price, worth every penny. Why spend $200 for a woofer that will not blow you away, when you can spend twice as much, for 10 times the return!

Rated 5 out of 5 by from just give TC sounds a tryI have been building car stereos for 31Years. Mostly useing 12 s and 18 s. From Fosgate to MTX 9500 . In the last 6 years the name Dayton has been on every subwoofer I have installed. Mostly the RSS models, which I might add, perform on a scale equal to or above that of the JL Audios W7 s. A year ago my son talked me into purchasing an Axis 15w1. We installed it into a 2.6 cubic ft. box with the TC sounds 15 inch passive radiator attached on the same plane. Very simple unit! Wow. The test equipment was showing graphs that most audio tech only dream about. These tests were done from the cabin of a 2000 Audi A6. The box was in the trunk facing back. Driven with a RF 15 bd. into 1.38 Ohms. You folks at TC sounds, "Very Nice". You Bass Heads out there, "Wake up". This sub will Jar very auto alarm in town, and sing to your bass loving heart. All at the same time. Promise!

I want to put 2 of these driver in a sealed, curved enclosure for home theater. What is the best cu/ft box size for 20 hz area ?

Asked by: Albq
I would recommend a volume of 4.5 cubic feet for both woofers. This will provide in room response into the low 20's.

Would this driver be suitable to use in a 3.0 cu/ft sealed enclosure with the SPL1000 plate amp?

Asked by: Andrew Hanson
Yes that volume and amplifier will work well with this woofer.

Can I put 2 of these in a dual opposing configuration wired into a 4 ohm load with a behringer ep4000? That's 4000 watts bridged at 4 ohms. The power would be split between the two woofers, 2000 to each?

Asked by: grassguy
These are quad 1 ohm coil subs meaning they can only be wired to a 4 ohm load each so two cannot be wired back to 4 ohms. You would be much farther ahead putting each sub in its own enclosure for better room placement options. The EP4000 will power a pair of these in stereo mode, although one amp on each sub bridged would be recommended.
