I've use Contact Cement in the past but it does dry up and fail after a number of years. Go to Home Depot and get some thing like "VELCRO Velcro Extreme" I've used these type of product in the past...

Ian, thanks for the link.

Very interesting approach to a sound system, I would have to agree with the presenter at 20K it would be hard to beat, assuming it lives up to its description which I...

The pre-amp is a KRELL EVO 202 with a KRELL 525 CD Player, the amps I'm using are KRELL EVO 600s & a 302. Its been about three months without the pre-amp and I have not felt the need to reinsert it.

I’ve just recently gotten into streaming FLAC files from my computer to a DAC then directly to the amplifiers. The CD player and pre-amplifier have been eliminated from the play back chain. I’m...

Hi Daz

I posted this on another thread sometime ago:

I have my K2 S9900s in a tri-amp bi-wire configuration and the improvement in sound is basically zilch. The only reason I did this was ...

The more I ponder it I think it comes down to HCSGuys astute comment:

“The 1500AL subs have the best definition I have ever heard in a sub, though I do have to add a little EQ on the bottom end”
...

I would agree with HCSGuy I have the K2 S9900 with a pair of Array 1500s. I find the Array 1500s slower that the 1500AL woofers, I put that somewhat down to the amplifiers KRELL EVO 600 versus what...

It’s been my experience (10 pairs to date) that used 2123Hs never sound as good as a 2123 with a new re-cone. If the 2123 doesn’t sound right it will sink your hole project as it plays a very...

I don't own a set of S9800s but I have 2235s in a 4344 and 2245s in a 4345 but the 1500AL-1s are still the best woofers in the house. I find the 2245s to be exponentially better than the 2235s and...

Not sure how you would add 1.5 cubic feet to the cabinet - might end up with expensive firewood.

I suggest you listen to them first, I think you will be pleasantly surprised, they do have a lot of...

Third time through the CD, an extraordinarily beautiful work of music.

Much thanks for bringing this to our attention!

Hi Brian,
All my speakers (K2S99/4344/4345) are on stands with wheels it’s the only way to live with them! Love the hobby but I’m so tired of dealing with 200 lbs. speakers.

With equipment that...

Hi TimVG
I would be interested in what you could do with the 2405’s in polished SS, wave-guide and phase plug. (3 pairs). I would also just settle for the wave-guides in SS.

Many years ago I...

You might want to consider the information in this thread when considering the SELENIUM HL14-50 as a substitute for the 2311 with a 2308 lens....

I would agree, I had the same issue - low output and there was a dent in the diaphram

I found a picture of my K2 baffles I once had the woofers out a few years ago. As can be seen there are two pieces of different thickness.

Here is a paragraph from the GT white paper on the K2 S9900 cabinet the information you are looking for is in the last section.

The transducers, horns and crossover networks are housed in a...

Well since this is sort of on topic...

Where does one buy a Truextent Beryllium Diaphragm for the 2446H?

I’ve only been able to find them at The Speaker Exchange....

I curious as to why you consider the schematic wrong as the section you are referring to comes from the JBL stock 4344 MkII schematic which has the C5, C7 as 72uF which in a CC network...

My understanding is that the 4344 MKII crossover will get you the smoothest sound out of the 2123 for this type of application. The issue would be the crossover point of the 2245 would have to be...

I have never heard that, the boxes sat around for a week before I put the 2235s back in so hopefully the initial degassing would have occurred. It been two year's now with no issues.

PS Like your...

Thanks Woody I have always admired your work !

The 2420 = LE85 which will work fine with the crossover, I have tried this.

Dang

I made a typo in the network schematic I have posted the corrected diagam in the original thread.
