NHT 2.3A vs. NHT 3.3 original model

In the mid to late 90's, NHT really began to build some decent products. The 2.3 upgrade was a relatively modest change. The 3.3 was a statement product. The 2.5 was an excellent product along with the Super 1 and Super Zero. The 2.9 gave about 90% of the performance of the 3.3 at a lot less money(although I personally thought it was somewhat bright and more closed in) Then they upgraded the 2.5 to the 2.5i with the metal dome tweeters debut. It was considered a great buy for the money.
In all, the 2.3A wasn't a bad speaker. It just wasn't up to the level of performance of the newer entries. A more fair comparison would have been between the 2.3A and the 2.5. I would still choose the 2.5 but they are closer. Hope this helps.
I have been and continue to be a fan of NHT. I think they make some excellent products for the money. The Super 1(or even the super zero) and a good sub like the SW3Pi made for a relatively inexpensive system with great performance. This combo bettered the 2.3A by a substantial margin.
Some of NHT's latest stuff like the SB3 has been getting some really good press.

I currently own the 2.3a's, 3.3's, 3 Audio Center 2's, SW3, VR-3's and a Sub Twoi... needless to say, I am a big NHT fan! The 2.3a is an excellent speaker for the money... I have A/B'd them in the same room with the 3.3's and they do present the basic core qualities of reproduction... just in a smaller and less refined manner. I personally felt that the 2.5 series was a step backward as they neglected a key trademark to the NHT sound... ACOUSTIC SUSPENSION BASS!
I like the 3.3's so much, I just sold off my B&W 801 Series 3 and got another pair!
Just a note to anyone here that is using 3.3's or 2.9's in a surround format... you are doind a complete injustice if you are using anything BUT the Audio Center 2 for the center or surrounds. The 3.3/2.9/AC-2 all have a similar crossover design that actually has the upper mid and tweeter OUT OF PHASE with the lower mid and woofer. I have used the 2.3a's(and many others... VR-3, etc...) as my rear speaker and noticed a less than ideal soundstage from front to rear. I recently got a pair of AC-2's to use as the rears and... WHALLA! Instant majic and an extemely engulphing 5.1 experience!
THANKS to member John Ashman for the AC-2... you have made my surround dreams come true!

I don't remember ever hearing the 2.3 before, but I own the Superone and used to work at a shop that carried the entire NHT line. Although every model seem to have an incremental change/improvement in design as you move up (larger bass driver etc.), the 3.3 is an entirely different animal from the guys below it in my opinion, and I am speaking only of the newer version with aluminum tweeter.

The main difference that mattered to me is transparency. The 3.3 sounds completely "boxless" with tons more detail.

Auditioned both speakers, 2.3A and 3.3. Could not afford the 3.3. I did buy 2.3A's. They are totally different speakers. If you can afford the 3.3's and can fit them into your room, buy them. The 2.3A wasn't that bad a performer. I personally feel that it bested any of the 2.5 series. It just needs a lot of good current. My speakers said 8 ohms on the back, but the manual stated 2.7 to 4 ohms nominal. They had extremely good bass down to around 35hz. I prefered the silk dome tweeter to the aluminum that replaced it. Just my opinion, the guy that I sold them to said that they were equal to his 2.9's in every respect, except for the bass extension.

the only downside to NHT regarding their "slanted baffle/focused gometry design"...the soundstage never gets outside of the speakers....granted they image well(but what doesnt at this level)...however they sound a bit "closed n" for my tastes...
