Looks like there are some other thread dealing with NHT speakers, I might as well add another one.


I already have a Yamaha subwoofer, recently decided to purchase a pair of NHT SB1 for rears and a pair of NHT 1.5 for mains. I was going to purchase the SC1 for the center channel to complete a home theater setup. Since NHT speakers are not very efficient, what kind of receiver should I be getting to drive these speakers?


I currently have an old Yamaha integrated 2 channel amp, 110 wpc, driving the NHT 1.5. The SB1's are still sitting in their box.


What kind of wattage should I be looking for to drive these speakers? I would like to keep the cost below $350. Anyone have any suggestions?

I have nhts (2.9,ac-2,vs2.4,nht subs and have had 1.5s,2.5i in the past. I have had over 25 different amps mated to these and at the price you want to stay at (350.00) the 5 channel amps that sound the best (imo) with nhts would be

Parasound 855

H/K PA 5800

SHERWOOD AM9080

As far as watts go all of the above drive the nhts just fine...On the other hand the sensitivity is around 86~87 and they can gobbel up as much power as you care to throw at em..hope this helps

Fourseasons,


When you mention Sony, Pioneer etc..are you refering to reciever amps or external amps ?...If you are talking about the recievers internal amps then no, I think you could do much better with any of the amps listed above..


Allen,


I havent heard them all but my favorite is the Brystons (which I currently have , actually lexicons but they are the same)..I am THRILLED to death wiht this combo...Parasound would be a good choice.....I tried allmost all the moderately priced amps but havent tried amps such as krell, class, proceed..ymmv


Dont let the occasional review that says the brystons are bright scare you away. Imo it is the FURTHEST thing from the truth..It is dynamic as hell and has allmost NO background noise, but not bright.


Oh, as to your other question, currently Im using an aragon soundstage as my pre-pro..but have went through allmost as many reciever/pre-pro's as I have amps.:rolleyes: ...My wife insists that Im some kind of freak

Hi guys,

You're now fully in MY territory. Here's the deal, NHTs, yes, are inefficient. That's how they are able to get such remarkably flat frequency response. But, they have a fairly benign impedance curve and won't break your amp. The only problem is that they are revealing enough that you will notice more about your source gear, but it is VERY hard to make these sound bad. Unlike many people that claim their favorite brand "only sound good with the finest ancilliary equipment", this is NOT the case with NHTs. However, they can go from good to great if you are more careful with your choices. The only problem with your Yamaha is that they tend to be a little thin and steely and it will run out of steam at higher levels.


If you really want to improve your sound, I highly recommend NAD surround receivers (in other words, save your shekels). They are the ONLY affordable receiver that can generate true "continuous power, ALL channels driven". This will make them perk up and fly even at very high volumes. Unfortunately, it really is the case that even companies like Denon, Onkyo, Marantz, Yamaha, "the good stuff", drops to about 1/3rd power when in surround mode. Yep, let me say it again, most other receivers drop to less than 35W/ch RMS with all channels driven. NAD receivers are going to start just over $500 for a T742 so if you can't swing that, look for a T751, T760 or T761 used in your budget.


The NAD 208THX (used) and 218THX (new) are excellent amps for driving 2.9s and 3.3s. They have exceptional bass control and dynamic range, yet aren't bright in the top end. Parasounds are also good for this. NHT even has 200W monoblocks that work very well and are getting many people worked up for about $700/pr NEW. B&K's work good, but you'd want the 200W models at least as the lesser ones don't have enough control in the bass. Rotel is also a good affordable choice. You can always buy even better, but you can OVER spend too. If you spend too much you could always upgrade to higher end NHTs.


As for inexpensive multi-channel amps psujohnny made are very good (is this because he also went to Penn State and is also named John?).


NHT 1.5s work very well with 60W-125W B&W amps as they're a little bright and thin. HOWEVER, slipping in the new SB3 crossover completely turns these speakers into a different animal.

Nice write-up John,


Your kinda right about my handle...My father went to Penn St. and Ive been going up there watching Joepa, basketball team etc. since I was 3~4 years old. I am brainwashed blue/white...and my name is John


I'd also like to second the notion that nhts can sound very good without gobbs of power, but the difference between nhts and some other brands is that they can take the added wattage and use it to sound even better...(some efficient speakers will sound the same whether driven by a clock radio or a 100 watt amp if you know what I mean)

Thanks for all the good suggestions guys. I only listen to music at moderate levels, most of the time I only have the volume dial a quater of the way up, and that'll be enough to get my roommate to pound on my door. I'll look into all the good recommendations you guys made.


Here is a question for you, what's your opinion on SB3's vs. the 1.5's? Is the new cross over in SB3 matter really that much? I've heard that 1.5's sound better than the SB3's.

Although I do have to admit, certain music does sound "thin" on the 1.5's, even when compared to the SB1's, when I had them hooked up as mains (I'm on a very limited budget).


However, a subwoofer really helps in this respect. Could this "thin" sound be due to the fact that the SB3 goes lower than the 1.5?

However, now that I think about it, I would describe the sound of 1.5 as a bit "cold" compared to the SB1. SB1's sound, if its sound even remotely approach the SB3's, can be described as a bit "warm."


I read some threads on this board that said the reason why the British 2 ways have a "warm" sound to them is because they have a dip in the 3-5 khz range. I'm wondering did NHT adopt the same approach in their new SB line?

SB1s - very neutral but not as refined as SB-3s


SB2s - ditto


SB3s - more refinement, amazing bass, a little on the warm side which helps get people in the door. Some people can't handle too much accuracy the first time around.


1.5s - Definitely thin, but image very well. The SB3 crossovers really work in the 1.5s, so if you have 1.5s, you can keep the sound you love and ditch the thinness. Bass is deeper, midrange is richer, treble is smoother, imaging is more natural.


Jack Hidley has told me there should be no problem with SB3 crossovers in 1.5s as the parts/design is so very similar (it is the new version, afterall), but he was just surprised there wasn't some unintended side effect. About 20 people have done this with nothing but positive comments.


Also, 1.5s with upgraded crossover imaging like crazy. Better than the SB3s, but many will prefer the overall sound of the SB3s to even upgraded 1.5s. BUT, the Evolution M5s and M6s are an absolute upgrade from both. Not even close in my opinion. the extra $300 or $600 buys you so much, it's absolutely incredible.


PS - John, I'm from Williamsburg PA. About 45 minutes down and to the right.

You should be able to get them from the local dealer. If they give you a "what, are you CRAZY?!?" look, I can get you some. We sell them for $75. Also, Jack Hidley of NHT, himself, will tell you that the crossovers were the weakest link in those speakers and that it was the product of an unfortunate cost-cutting manuever to keep the speaker under $600/pr. I think they'd have become legendary at $650/pr with the proper crossovers. They've learned from that and all new NHTs have excellent crossovers for their price point.

John,


Do these new crossovers also work with the other music series models: 2.5i, 2.9, 3.3, AC2? Is it hard to replace the crossovers? I currently have 3.3 mains, AC2, 1.5 sides, and SZ rears.

Replacement is easy. A screwdriver will handle it. 15 minute, 5 with a powered screwdriver.


I haven't secured anything that will work on any other model. I have tried to get the original "high-end" crossover for the 2.5i, but no luck. They can't find it and don't have the time to reconstruct it. The SB3 crossover was almost a fluke. Other attempts to transplant failed miserably.

john, thank you for the 1.5s' x-overs info. i'll check with my local NHT dealer see if i get them there - else i'll get them from you. i've read your posts with great interest because i found myself coming back to NHT after auditioning a number of speakers. i guess i like the NHT's sound. is the tweeter in the Super Series the same one used in Focus Image Series?

It's the same as in the Evolution series if that's what you meant. Evos use "virtual" FIG while the original 1.x, 2.x, 3.x models used FIG with different tweeters. The new tweeter is pretty amazing. The more I listen to it, the more I like it and that usually doesn't happen. Things with me usually go downhill........

Well, after months of research and no one talking about NHT I thought I was the only one lately who has purchased these things.


In the super audio series, I heard that they just released another center channel to add to the line....the SC-2. Anyone been able to listen to it yet, any better/worse than the SC-1? Thats interesting you say the SB-3 is a much better x-over than the SB-2. I tried all over to find a dealer to demo the 3s but no one had them, so I settled for the 2's assuming the only difference was the fact it could go a few Hz deeper?


I only have one pair of SB-2's coupled with my Sony DA4ES. I am still trying to figure if I want to go with SB-2s all around. or maybe the 3s up front and 2s in the back with the SC-2/SC-1.


I am leaning with the 6.1 with all 6 being SB-2's though....let me know any opinions :)

I think John Ashman is trying to say that SB3 has better crossovers than the now discontinued 1.5 series. SB3 and SB2 should have similar quality crossovers.


I have a spare pair of SB1's, if you like, PM me or send me an e-mail.
