"Better" is relative and highly subjective.

I owned an MX-1 but I sold it. I currently own four GFA-5500's. The MX-1 had faster, tighter, more detailed bass than the GFA-5500, but I preferred the...

Glad you are back in operation. I wish we could have found out what was wrong with the dual mono configuration.

Sure. Whatever you say.

That's what stereo is about. Congrats!!

Blackhole 5 was installed in my SDA SRS's. The performance results similar to those achieved with the SDA SRS 1.2TL's, so I won't rehash them.

Are you going to connect the ends of the two side panels to cut down on vibration?

Polk's passive system is the most natural sounding of all the interaural crosstalk cancellation systems I have heard because it does not do anything to the original recording . It only removes a comb...

This is good advice. The more noise burden you remove upstream of an AC regenerator, the less hard work it has to do and the better its output. I'll try filtering my other household devices.

The red metal sculpture between my turntable and SACD player had to go. The greater output due to the Blackhole 5 mod was causing the sculpture to audibly vibrate and ring. I didn't notice it until I...

Sorry about your troubles. I would have expected better from an audiophile-oriented company like Madisound.

Are you building an external crossover? I know you are not going back to the days of...

I considered Norez, Sonic Barrier and BH5. BH5 seems to be better suited for full-range speakers than Norez. It came down to a choice between BH5 and Sonic Barrier.

I can't imagine ever getting rid of either of my big SDA's (the 1.2TL's or the original SRS's) or my versitile CRS+'s. Speaking of SRS's, I need to order another sheet of BH5 for them.:cool:

Yes! Keep your eye on the flea market next April. I am expecting to have found a suitable high end alternative speaker by then.

Cut to make best use of the available material. I would have preferred the side strips were a little wider, but I didn't want to buy another sheet and have a lot of left over material.

I thought about cutting it with the band saw in the machine shop at work, and I would have, if the kitchen utensils hadn't worked out.

Have you tried the polarity reversal tests?

Did you use a single 2" wide strip down each side in the driver area or multiple 2" strips? How long were the side strips?

I recall you doing the Sonic Barrier mod, but I didn't recall the BH 5 mod.

I am just going to put strips behind the drivers and tweeters similar to what drumminman did with his 2.3TLs.

They are, but I consider them part of the cabinet.

By the way, I ordered a sheet of Black Hole 5 today. One 24" x 27" sheet is enough to treat both speakers. I'm not looking forward to gutting my...

Stock. Thanks for mentioning that. I did consider replacing the polyfill. Ken Swauger suggested a replacement material, but I could not find any conclusive evidence of a "better", rather than just...

Polk recommends using either the bass brace or spikes, although I have read of people using both. In my room, the bass brace sounded better than spikes. I have not tried using the bass brace and...

It is always amusing when we SDA enthusiasts are reviled for daring to use our 20+ years old SDAs with modern, and often very high performance, electronics and cables. It is amusing...
