Alon/Nola sound
One issue all Nola Viper series owners need to be aware of and that is that the Positive and Negative terminal tabs on the midrange drivers need to be adjusted so as not to come in contact with the cabinet. The midrange opening on the baffle is VE... 
high pass filter
Hey Duke, I was just going to suggest that the OP consider using a line level x-over instead of the high level route which at the 80hz frequency can be rather daunting.Harrison Labs makes two such line level x-overs called the FMOD or the PFMOD an... 
high pass filter
Let's make this easy, for a ~4 ohm impedence at or around 80hz, you will need the following:6db - 500uF cap12db - 350uF cap, 11mH shunt coilFor ~8 ohm impedence:6db - 250uF cap12db - 175uF cap, 22mH shunt coilThese values will get you in the ballp...

As Kr4 said, a cap will do the trick BUT you will need to know the impedence of your bookshelf speakers at 80hz and whether you want a shallow rolloff(6db per octave) or a sharper rolloff(12 or 18db per octave).Also, the quality of the main cap wi... 
So what is the best speaker you have ever owned?
Hands down Nola Viper 1AX. Bottom line, these baby's reproduce MUSIC way above and beyond most any speaker in their price class and above all the speakers I've owned or still own including several Alon's, Cabasse, NHT, Fried and MartinLogan. FWIBT... 
Tube issues, 12at7 affect KT88?
Hey Tony, I have the same amp and have had the very same problem you have. The 4 12AT7's provide the bias to each KT88 output tube thereby if one 12AT7 goes bad, then the corresponding KT88 will glow cherry red. The Mac's are built rugged and ther... 
Do tweeters with open rear chamber need enclosure?
"But they still need a baffle or sound waves will cancel."Are you familiar at all with Alon/Nola speakers? Those models that employ the dipolar topology for the midrange and tweeter drivers have the drivers mounted on a baffle.The Alon line had a ... 
Do tweeters with open rear chamber need enclosure?
Not when used in a dipolar topology as Alon/Nola has been doing for years with VERY good results...~ 
Has anyone compared the Nola Viper IIa's..
As a long time Alon and Nola owner and having a pair of Nola Viper 1A's in the main rig and a pair of Alon Lotus SE mk ll's in another both driven by tube amps, I can say with extensive experience that the Viper 1 and ll's are a trickle down speak... 
Nola Viper Owners, Lend Me Your Amps
Being a long time Alon/Nola owner including 2 pairs of Alon 1's, 1 pair of Alon Lotus SE mk ll's and Nola Vipers 1X's, I can tell you they all sound their best IE natural with tube amps although a Pass Labs Aleph 3 did very well with the Alon 1's....

Audiophile speakers that rock well
Being a die-hard rock and roller with some heavy metal thrown in, the speakers that have consistently delivered the R&R goods have been both the Acarian Systems LTD. Alon 1's, the Alon Lotus SE mk ll series and the Accent Speaker Technologies ... 
do f-mods work?
Yes I have tried the PF-mods/2W1 and while they do work, they are not very high quality and one can only use cheap IC's with molded RCA plugs as the plug spacing/opening is too tight/small. I had to remove the shell to use them with my AQ and Audi... 
Speakers for 55 watts of EL-34 tube power ?
One of THE most musical combos I assembled was an AMC3030a integrated amp which used PP EL-34's and Acarian Systems LTD Alon 1's coupled with MIT2 Bi-wire speaker cables. The bottom octave was covered with a HSU Research HRSW12V sub which plummete... 
Heard McIntosh 275 For The First Time.
While the stock MC275 IV is one hell of a musical amp with it's stock tubes, one can significantly increase the amps resolution and musical attributes by replacing all of the stock tubes to begin with. I swapped in quad matched Genalex KT88's and ...
