They are the Genesis 2 model. This is just a pic of the speakers, and mine are not for sale...

Has anyone ever looked at the Genesis woofers with servo feedback. These are getting old and wondering how we might upgrade them with the old enclosure.

Any pictures? Whats the cost, and I only do PayPal for purchases. Thanks, Mark

I'd bet Bob has taken a beating internally every time he has to justify a lie. But he may not have any morals left and only cares about the money. Hell, his credibility is shot with thousands online.

Still looking for one.

Head over to Whats best and look at all the dick swinging regarding cables, routers, LPS, and a host of other overpriced crap. Every added dollar or tweak somehow improves the playback. Any push-back is met with derision.

These were the oil bath filters of long ago. The air flow made a 180 degree turn and passed over the oil which trapped the dirt particles. Filter media was usually a wire mesh. Washable and put it back together.

Most people don't consider planned obsolescence as part of the manufacturing process. Plastic bottles, bags, and a host of throw away parts that are non-rebuildable. All part of the "let em buy another when it breaks/wears out". The old cars had a oil filled air filter that worked very well...

I am not sure what the problem is with Foobar and its use. I set up Foobar with the convolver using the files generated with REW. Coverflow has been a nice addition and gives it a more updated look/feel. Most people only need to correct the low end response between 20 to 400hz or so. Math Audio...

Bump. Anyone??

Want to buy a Topping D90 in Black. Non MQA only. Thanks, MAK

Looking for a black non MQA model. Your pics do not appear in this listing. Contact me. MAK

You can use your laptop or PC to measure with REW. The cost: Zero. Next is a Umic-1 to measure with. If your receiver has built in room correction, look to see if the sub can be connected to it as well. What receiver do you have? MAK

You could not differentiate the sub Left and Right output below 300 hz. There is no directionality to discern each channel. Case in point is my systems woofer towers. Does the Left column sound different to the Right? I honestly cannot tell. I would have tried to move one of the towers to the...

Put your subs at opposite ends of the room and do a sweep with REW. I'd bet the null will flatten out at 63 and 71hz. REW room sim will show this as well. Your overall measurement may flatten out from 20 to 300 hz. MAK

Here are some corrections I made from 15Hz to 300hz. I did not try to boost the dip in the Left channel at 74Hz. With the combined corrections the graph looks much better to me. Paul, I added the Left spectrogram with my corrections applied. Comments welcome.

Paul, I hope that this is what you are asking for. I cannot attach the .mdat files to look at here. In the "target settings pane" are there specific settings I should be using for the low end correction. MAK

Guys, I tried several times to correct the hump at 32hz and the loaded filter sounds bad. The bass columns are sealed, 4 drivers per column x 2. Not sure what the target settings should be. I am wanting to correct up to 300 hz. Crossover it at 85 hz. Phase at 5. Your input is appreciated. MAK

Here are some sweeps after moving the Bass columns around for the afternoon. A much improved response to me based on the sweeps taken. Next is how to correct the bottom end so I have some results that sound good. MAK
