I have been looking at a Marantz MM-7025 2 channel amp, but the way I have been hearing from here is that would not bring up the bass level.

You need to change something about the relationship between the speakers and the shape of the room. This is my listening area, about 14 feet from the A/V center. I'll work on the suggestions today & tomorrow that were given in all the previous posts. 1 Quote Link to comment Share on other sites More sharing options...

It sounds like you're sitting in a bass null area. Speaker as well as listening seat position can go a long way to fix the problem. As stated before, with bass heavy music playing (I usually find a part of piece of music that has this quality and put my CD player on a-b repeat of the passage) move around the room until find the spot with more bass. This may seem silly, but do you have an office chair with wheels that won't scratch your nice floors where you can scoot around the room while seated to do this? This will keep your ears closer to listening height. Sometimes the nulls and peaks are present at different heights also. The bass is always the strongest just before entering kitchen and next to door on right of the picture. I'll work on many of the suggestions over the weekend, but first will be taking a look inside my speaker cabinets for the first time, to check polarity connections.

I think many other forum members would also have suggested the same thing earlier with more of the details upfront. Bass null problems are sometimes difficult to express and understand.

I wondered about your polarity earlier, but the way you further describe the condition, it is most likely a room mode bass null at your listening position. I suggest you start by placing the speakers up on tables or chairs and listening with Audyssey turned OFF. Quote Link to comment Share on other sites More sharing options...

If you are running a sub in the system try positioning the sub there. Quote Link to comment Share on other sites More sharing options...
StratCountry Posted September 13, 2019 Author Share Posted September 13, 2019 I removed all the screws from the radiator speaker but having trouble pulling the speaker out. I took a small flat screwdriver to pry it out but I'm leaving indentations into the wood which I don't want. Any safe way removing the speaker without leaving any markings?

RRR Posted September 13, 2019 Share Posted September 13, 2019 Unhook it and lay a large towel on the floor and prop it up at a 45 degree angle and try again as the gasket may have gummed up over the years. 1 Quote Link to comment Share on other sites More sharing options...

I tilted it to almost 45 degree forward until I felt the speaker cabinet slipping on the floor. I'll have to til wait this weekend and have someone help me tip it forward farther. I hate to have things go wrong. Quote Link to comment Share on other sites More sharing options...

There should be a little slack in the wires. Reach in with your fingers until you feel a part of the woofer basket and give it a little push out on the basket, not the cone, ready to catch it as it pops out. I just did this a little while ago when I installed Crites crossovers. Not sure what you mean about 6 screws holding terminal cap. Quote Link to comment Share on other sites More sharing options...
moray james Posted September 13, 2019 Share Posted September 13, 2019 this would be a good time to install all fresh gaskets all over including the terminal cup and while you are inside make sure that the mounting holes for the grill are all sealed with caulking. This will insure the cabinet is air tight which is essential for best bass response. Quote Link to comment Share on other sites More sharing options...

It sounds like you've got the null thing nailed. That's what it sounds like to me, too. If you haven't moved the speakers yet that may be your best bet to deal with that null. Something else you might do because it costs you nothing to try: Try using Double-bass. See if that smooths out the null. Quote Link to comment Share on other sites More sharing options...

I removed the speaker terminal box and was able to push out the speaker which took quite a bit of force to pop it out. Connections are correct. Seems like their should be more foam inside the cabinet, only on one side which is 1 inch thick? Everywhere else is bare? Could this contribute to the bass issue?

No, there was minimal foam to begin with. If i recall that foam pad was U shaped on the bottom of the cabinet, it was probably moved to install the crossover there. Nothing to worry about.

Put the lamp and anything else that will fit back on top and play some tunes. Or put the sub in place of the teddy bear bench 🐻, then test. That could be a good perch as well. 😀 Or put it right by your chair and see if you can turn that chair into a massager.👍 Quote Link to comment Share on other sites More sharing options...
StratCountry Posted September 13, 2019 Author Share Posted September 13, 2019 Funny thing, after I put everything back together and torqued all the screws a bit extra, the bass is now more pronounced! Even while sitting in my recliner. This without the sub on, probably no longer need it. Before, the volume had to be up between 40 and 50 to get my pant legs to ruffle, 50 was the max my ears could take unless out on the deck. Now, volume at 25 , I can feel the rumble throughout my body which is more of a comfortable listening level. 1 Quote Link to comment Share on other sites More sharing options...

The adjustment often marked "phase" on a subwoofer -- a two position switch -- is typically just polarity. The multipath problems that can occur with a sub and a main, with the main set to "Large" and the sub working (usually requiring something like "LFE + Main," another misnomer) can take the form of valleys or peaks and valleys. In some rooms, with some positions, no problem. I've tried both, and although it is no big deal with my set-up, I eventually decided on "Small" for a bit of extra clarity that may be illusory. If you get a second sub, it should be identical to your present one because if you want to use Audyssey (and I think you probably should) when Audyssey scopes out your F3 for each sub, it will limit correction to above the F3 of the inferior sub (unless they have changed that feature). Mike's Guide should help here -- see the Table of Contents -- I think you want VIII--C. Quote Link to comment Share on other sites More sharing options...

If I still have the null in my chair using the sub, I'll move the sub around, but not til tomorrow. I have enough bass now. I'll probably move the sub next tmy recliner, always wanted 2nd table by my chair. Thanks. 2 Quote Link to comment Share on other sites More sharing options...
