I totally agree westend, Marantz's are magical.Originally Posted by westend9
Muahahaha, glad to hear I'm not the only one with termination issues.I had a 2270 and thought the phono section was pretty darn good. The 2270 was just a lot of the same Marantz goodness, IMO, very robust amp section and that signature sound.
Here's the guy I went to he appears to be really good with them.

I'm thinking of buying a new amp. Does anyone out there know if the new Marantz amps are still "good"? Or, are there any other solid state amps that are currently being manufactured that anyone cares to recommend that would work well with high efficiency Altecs? Sorry for the slight detour of your thread, Cradeldorf.....

Well, it's not an Onken alignment, just looks like one at a glance. Based on your remarks, you would find a true Onken or Jensen Ultraflex alignment way too 'punchy'/'boomy'.
Yours is ~aperiodic, i.e. is somewhat resistively loaded due to having very high aspect ratio slot vents. You can get the same result with a regular reflex by stretching cloth of the right porosity over it ['click' test]. Yours are also next to cab wall boundaries, so are acoustically fairly long vents which combined results in a slower roll-off [better transient response] to a lower Fb than the smaller reflex vent. Pushing them up close to the wall further lowers effective vent length, so my SWAG is that yours are effectively an EBS alignment.
Bottom line, a very good venting choice when speakers are located near/at a wall or corner, though sealed or very low tuned [< 20 Hz] EBS alignments tend to be best overall for corners.

Thank's for the clarity Greg, I tried something different this morning...it was a total fail so I put it back the way it was and it sounds re markedly awesome again. I can't explain it all I can do is comment on it, Loving them right now. They sound best when I keep them about 8 inches off the side wall and about 4 -6 off the back wall.

You're welcome! What did you try, etc.?

This. It was horrible.I was shooting for just a little more openness sounding and maybe a little more bass. It was a little more open but about as far away from flat as you could get. you could hardly make out what people were saying and the lows were crazy loud.
That good and funky! Thanks for sharing.
OK, never seen anything like that before. You're obviously leaving no stone unturned in your search for the ideal tuning/porting--got to give you credit for that!

A variation on G.A. Briggs's ~aperiodic vent. He used many parallel saw cuts. Wider ones need to be covered with an empirically found damping material. As is, it tuned your cab somewhat higher.
One inexpensive variant to try would be a rear cover made of braced pegboard.

Funny you should mention that because that's exactly what I was picturing because when I was a we little lad we used to have a stereo console and the back panel had a bunch of about 3/8 holes in it right where the speaker backs would be. That's actually what I had in mind when I did the slot thing, by making more smaller ports would give me a better more level sound. Now I know (thank's to you) that I should have at least stuffed some polyfill between the slots or something like that and not just leave them wide open. Plus the backsides of all those boards had no insulation or anything on them so probably had a lot of reflections going on inside.
