Rules for matching subwoofers to room size
IMHO, If there is any stereo information below 70 Hz (and with an LP there won't be) the SW will be easily located.I would stay away from 10" subwoofers which achieve their SPL by extreme cone excursion that results in distortion.A quality 12" or ... 
To bias or not to bias
Many tube amps used a self-biasing tube circuit (not the same thing as auto-bias). A self-biasing tube circuit has no means of adjusting bias. This eliminates the need for a bias voltage power supply. Eico offered one amp kit in both self-biasing ... 
Hertz Meter Reading Device
I have a test CD (CO-75046 put out by Denon) which has tracks at 4, 8, 17, 31, Hz, and up. I think that the lowest tracks are for use with electronic test equipment.My subwoofer cones do respond at 8 Hz, but I hear nothing, which is not surprising... 
Hertz Meter Reading Device
My gripe about frequency response specs is that they ought to be measured not only relative to the SPL level at 1000 Hz, but also AT some particular SPL level at 1000 Hz. If the SPL is very low the woofer will not run out of excursion and the LF p... 
New FedEx Ground and USPS Arrangement
Did you know that at one time the post office only handled letters...no packages. The private Pony Express shipped packages. But they didn't deliver to sparsely populated areas.It was the Socialist political party which proposed that the Post Offi... 
New FedEx Ground and USPS Arrangement
I thought that DHL had folded their tent in the US. (They are big in Europe).My son is a pilot who flies a small plane for Fed EX out of Phoenix to nearby cities like Flagstaff. He used to do the same route for DHL, but went to Fed Ex when DHL qui... 
Do You Hear Print-Through on Trinity Revisited?
If recorded in a church with long acoustic delay that is perhaps what you are hearing as the POST-echo. 
Do You Hear Print-Through on Trinity Revisited?
Adjacent groove interference affects grooves both before and after, although it is generally only heard as pre-echo during a silent or very low volume groove. Is the delay equal to about 1.8 seconds, the timing of one LP revolution? 
Center Channel Frequency Response
Lhf63...Actually, it was the second post that began the off-topic remarks about spelling. Lighten up. There is more to life than audio. 
Center Channel Frequency Response
Lhf63...Research on this topic has been conducted mostly in context of noisy environments such as you describe. However, consider that the dialog of a movie is heard against the background of all the other sounds on the soundtrack. This is indeed ...

There are several versions of this...Eye halve a spelling chequer It came with my pea sea It plainly marques four my revue Miss steaks eye kin knot sea. Eye strike a key and type a word And weight four it two say Weather eye am wrong oar write It ... 
Center Channel Frequency Response
I don't have a lot of movie DVDs, but at least one ("The Bridge on the river Kwai") has nothing but dialog in the center channel. And, you can have it in your choice of language.Anyone who is familiar with my comments will know that I am a strong ... 
Center Channel Frequency Response
That quote was from me. OK, OK, so I don't always spell correctly. I'm sure you guys never make a mistake. You guys really need to do some research about reproducing speech for best intelligibility. Much research has been done on this subject, par...

"My Dynaco MK II" means you already own it. Try it. What do you think? 
Will my Dynaco MKII power My Magnepan MGII's?
Yes. And it will sound great!
