The Titan is absolutely superb. No it doesn't play as loudly as some other subs, but it sounds better than all the subs I've auditioned, and I've listened to most of the good ones! The construction is 1st rate, I've seen $5000 speakers that weren't built this well. My wife says it looks and feels like fine furniture!
If you are serious about music or video, you've got to listen to this subwoofer. Take ACI up on their money-back guarantee if it's not the best you've heard, but you'll be keeping it like I did!

Build quality, accuracy, musicality.

Control knobs need better markings in order to see easier.
This is a heavy sub and rather large if that is an issue.

I wanted a sub for music. I listened to all of the those listed. I bought the ACI Titan based upon reading reviews here, magazine reviews, and the ACI website. Found a good deal on a used one. The warranty is transferrable if you can verify the original owner. ACI staff were helpful and I ordered the spikes and some cable for it at a fair price.

This sub has great presence and musicality. You can actually hear the instruments rather than a muffled thud sound so common to many subs. It adds a very subtle, smooth, and understated depth to all recordings. It can get loud if you like that. I am sure it will do HT just fine.
Setup and placement does not seem to be very difficult.
I am very happy with my purchase and am considering other ACI products.
The only sub that sounded as musical was the Monitor Audio 110, but it did not have the overall depth of the Titan.
This is a great sub.

I have know owned my ACI Titan powered subwoofer for 3 months. First of all let me say, that I was very impressed with the build quilty of the Titan. The finishing is outstanding,as good as any subwoofer that I have seen under the $2000.00.
When I first got the subwoofer I was not overly impressed with the sound (I am using the Titan in my Hifi system) but after putting 15 to 20 hours on the subwoofer it began to make music.
Talking about music, this is what this subwoofer does best. The lower bass detail is very clean with little or no bloom. I have married the sub with a pair of ProAc studio 150. The subwoofer adds weight to the bass without bring attention to itself.
I spent 23 years in the Stereo business before retiring and I remember few products that represent such great value for the money. I would compare it to the NAD 3020 of 20 years ago for value for dollars.
ACI as a Company are great people to deal with, they answered all my questions and even doubled their normal trail period for me because I live in Canada.
Good on you ACI, the Hifi hobby is still affortable because of manufactures like you.

When I purshased my complete Magnepan Home Theater System using the upgraded MG10.1's as my mains I was really not considering upgrading my Klipsch SW12 sub. Unfortunatly the Klipsch just didnt have the speed like the Maggies. I listened to many subs but anything that had the speed was well over $1000. I turned to ACi because of a previous purchase. The production Titan is downward firing which because of placement it would'nt work. I needed front firing. Enter Titan Kit. I can build almost anything and I have the shop to do it. Mike at ACi helped me with the demensions and construction was completed in about 20 hours. The kit took about 1 hour to install. The moment of truth is very scary, its not like you've heard in a store allready. The sub is awsome. Musically the accuracy is mind blowing and its fast. It can be gentle like a lamb or roar like a lion. The Klipsch had more knock you out of your seat bass but no defination. I do not know how low it gets but minuatures in my wife's shadow box on the wall are taking the "plunge" to the floor. That's new. Total cost came out to be $625.00.The production Titan sells for $799.00. Based on what I auditioned at the stores I would have had to spend $1300 to $1500 to get what I got. ACi is audio's best kept secret and the word should get out.

I spent six months looking and listening to subwoofers. Most of the them were very slow and had a lot of bloom in the bass. I was looking for a subwoofer that had good bass detail, because I am using it for Hifi not HT. I owned a Paradigm PS-1000 and found that it was VERY slow and did not have good detail in the bass. The ACI Titan powered subwoofer has great detail with very little bloom in the bass. I mostly listen to Jazz and Clasical music and I was looking for more wait and detail then my ProAc 150 were givening me. I listened to the REL 100, which is also very good but I also need a subwoofer that went with the decor of my living-room/listening-room. The Titan comes in cherry wood, which my ProAc are. I was not very impressed with the Titan when I first got it home, but after 10 to 20 hour of playing time it tranformed itself into a subwoofer which has great detail and Very good timing. It matches very well with my ProAc's, it adds a lot of dynamics and detail to the music.
The people at ACI are very good to deal with, they answered all my question in a very freindly way.
This is a good Subwoofer for the money and I would highly recommend it for anyone that is looking for a musical subwoofer. This is not a $3000.00 subwoofer but for $800.00 including shipping it a perfect 10
