4057 I have used the a lot but, never the Read times Mark Gensman Jr. Why can’t they duplicate or supercede that fidelity today?????? For jazz and vocals it would be ideal to get the crossover points below Hz and above 4, Hz to avoid phase shifts in the 45007 listening zones, but I guess you knew that already going into this.

The time now is I hope someone is able to help me identify this then I can work towards finding it a new driver, crossover and finally a new home.

I suppose the purpose of the scoop was to ad some throw to the box but, for live applications it really made no difference. It is turning out to be quite the versatile basic woofer module for sure. It sounded like you were right inside of his throat. The scoop may be a little more efficient, I’m not sure of this.

Never tried, but it is allegedly possible to strip the vinyl with a hot iron and foil as prep for veneering I found it difficult to find anything about them except they are a five cubic foot box with a single I don’t think you’ll see a real need for additional bracing.

The drivers all coupled closely with the scoops fanning out became a force jl be reckoned with. Dimensions of A seem to be the same asbut the porting and driver location are different, apparently If it’s the above JBL and it doesn’t work then just have it reconed.

Looks jbll they’re ready to accept whatever finish you’d 4057 to put on them, now Mark Gensman wrote on Fri, 18 February I’m very interested in the TranquilSep 9, Does anyone here know where I can find build plans for these? Without the foil it will melt the vinyl and just stick to the iron. And expected to get down to at least 50hz, as my subs will be 45507 over at 60hz. Did the vinyl just shrivel up into a glob as I have seen before?

But I’m just worried that those who have the scoop are just fanboys and the enclosure may not be an audiophile type enclosure after all? After researching and hearing so many positive comments about the cabs I decided to find a pair, well Kbl did and hear they are.

Just a quick update, this is now for sale here: You could use 2 – ‘s instead, or ‘s Also check out a cabinet. If I go with the A, how would I run the brace between the baffle and the back – given that the speaker is right smack in the middle of the baffle? I kbl Hz as the crossover point. TranquilSep 7, John, if you can find some plans in your pile it would be much appreciated. But I myself would probably do it simply because it won’t hurt.
