Stating what setting your volume knob is doesn't mean how loud the system is. Your loudness level should be expressed in Db's not what the number is on your reciever. you need a Sound Pressure Meter and a known distance from the source(s). Such as: 101 db @ 1 meter

Try reversing the polarity on just one of the speakers to see if this improves the bass. What size of wire are you using now? 18 gague is OK for short runs, 16 gague and up for longer runs. What amplifier are you using? if you are using an AV reciever/amp you need to check to see what the front speakers are set to... Small or large. if set to small, then the reciever strips the lower bass out of the signal sent to the speakers. And finally, what other speakers are you comparing the Cornwalls against?

When you say deep bass are you talking about frequencies below 40 hz or so? The Cornwall produces excellent bass response but it is NOT a subwoofer. I am thinking that you may have a phasing problem with the connection of your speakers. Please check to ensure that the + (positive) terminal on the amplifier channels are connected to the + on the speaker. Of course the same goes for the - (negative terminals). If these appear correct, then reverse one of the speakers, that is, put the + on the - terminal and the - on the + terminal. Try playing the selections of music that are bass shy and see if it helps. If you still have a problem, then the crossovers inside the speakers may need ot have their capacitors replaced.

One Epik Conquest would do it! []

I agree with Thebes. I have a Fisher 500C. Yes, it has 3 channels. 2 are active and one is a derived center from pulling off of both transformers. I use it to power my K-B-K setup. Fisher was gone over by Terry Dewick in Knoxville. It gets plenty loud!

I'd like to fill you in a bit on Mr. Terry De Wick! I met Terry a coupe of years ago when I dropped off a Fisher 500c for a rebuild. I was able to find his house easy enough with the Tom Tom. He lives on the western side Of Knoxville, TN in a quiet, older part of town. I knocked on the door of his double garage that had been converted to an electronics workshop, one side was FILLED with all types and kinds of recievers and had Macintosh gear everywhere.... on the other side of his garage was a 50's or 60's Woody in teriffic shape... More to my absolute surprise was to find out that he was an old ASAer (US Army Security Agency). He was stationed in Ft. Devens most of his time in the Army, it was during his Army time that he was trained on radio/crypto repair, and we are enjoying the benefits of that training even today. Terry was in the Army during the mid 60's so he was in during the tube days. Terry and I hit it right off!, I too was in the ASA as a 31J20-B3 Teletype repair so we just sarted in talking about the "good old days" it was most difficult to leave that evening. As a true ASAer Terry has his share of "Now this is no shit" stories about drinking beer and driving his Woody around Ft. Devens. On the technical side, Terry's bench was full of test and repair gear. He had a Mac sitting on his bench going thru a post repair burn in, he had stacks of gear in boxes waiting for his expert touch. the bottom line up front is that I highly recommend Terryand the work he does. My Fisher sounds teriffic now, its around 45 years old........ brought back to life by Mr. De Wick....

It all depends on the signal level you are feeding your sub

ALWAYS use a good quality surge suppressor, ALWAYS!!! Not some cheap Walmart power strip but something that will STOP the surge and noise from passing on to the sub. Something from Tripp-Lite should do the trick around $30-$50 bucks. If not.... it's just a matter of time before the electronics just die....

It would be a good thing to rework the crossover in those if they haven't been touched yet, 1959 is a loooong time ago!!! Though that Ebay add said 1000 watts I wouldn't push them too far without a rework on the crossovers. It's a relatively cheap fix.

The "double drywall with Green Glue on walls and ceiling" is a great idea. I wasn't thinking of the sound leaking out to the main house, just a way of helping to keep the resonance down in the space between the walls. I have used the Owens Corning Pink fiberglass batts that are paper backed on one side.

In both corners where the Korner horns will be, place the 2x4's every 8" on center instead of every 16' on center. i would also use some construction adhesive (or drywall glue) on the drywall/2x4's just so they won't rattle. Of course, it would be best if you could glue and screw all of the drywall in that room. Are you going to put in any insulation? That will help a great deal too. If the walls are empty, they could ratttle when your system is cranked.

That's what I would do. I would also try and brace the corners with added 2x4's for the first 4 feet on both sides. It's a cheap way of stiffening up the wall behind the speaker. It can't hurt! It's much easier to do BEFORE the drywall goes up!

If you put the Khorns in the corners of the 15' wall, your listening area (sweet spot) will be very close to the front wall. Placing them along the long wall will give you a better soundstage. I've tried both, the long wall is the best placement option.

Email sent! Thanks for offering this!

Jon, I was wondering where those Cornwalls went to!!!!!! If he ever want to get rid of them, I am ready!!!!!! I know where you live!!!

I would look at some 12 volt fans from Tiger Direct, New Eqq or Geeks.com. Get a couple of them and a varialbe or selectable ac to dc converter and run them at 6 or 7 volts. You will get plenty of ventialtion and you will not hear the fans at all. The power supply can be purchased at a Radio Shack. I have done this for many years on my equip and it keeps everything cool. Remember - Heat Kills!

How about a vintage Fisher 500C? I had it rebuilt by Terry Dewick a little over a year ago. Still puts out 35 watts per channel.

Sorry, but the wifey likes it the way it was.... The WAF you know!

Actually I do listen down there, i just lean to the right a bit!!!!!!! []

For the size it's a killer room. The wall treatments help a lot I believe. As it is it is also a good listening room with the Corns. My main listening room is right above it with a pair of Khorns and a Belle center. The Sub?... Way overkill for the room, but mo' is betta, right? My son and I ran frequency sweeps and the thing put out below 10 Hz.

You may find something in the 2 Channel thread..... Solid State or Tubes, or both!

The right place for Video. Now if you want to start a thread on listening rooms.......

14' wide 20' deep I have a Onkyo TX SR 606 for the control center. More than enough power!!!!!

Looking from the front to the rear..

Yes that is an Epik Conquest subwoofer!!!!
