Bought some more powerful subs for my folded horns but turns out that the surrounds on pretty much every 8" sub capable of more than 400w power handling is WAY too big to go into the sub cavity of the horn. So I put the Daytons back in and played around with the DSP on the amp a bit more.
Have a bit of a bump at 40, 60, 80 and 100hz for the subs (3, 2, 2, 1db resepctively) with HP set at 20hz and LP set at 120hz. The slopes are Butterworth 48db/octave on the 20hz side so it drops off a cliff and then a Butterworth 6db/octave on the 120hz side so the slope is nice and gradual.
Seems to be giving me most of what is missing on the low end due to the room modes/nulls. But it is still not as good as just the speakers themselves in that damned hotel room at LSAF. The problems of dealing with a very compromised space.

Got a used Micro Seiki MA-505 tonearm Yeah, it's missing a couple of bits, but those have been procured and are in transit. Bearings are in perfect working order. Ok, it's a little rough around the edges, but I got a good deal on it, and it should clean up enough to suit me. I'm much more about function over form when it comes to cosmetic issues, but that's just me.
Very nice. I've got a variant (not the 'standalone' unit you have) on my MS DQ-50. Been a fine performer for me.
Cranked it up for the first time in a week or so. Still smiling from ear to ear

Received some Wireworld Mini Eclipse 8 speaker cables today. Preparing my self for a little shoot out with my current with my current Zu Libtec speaker cables.
I have a ton of CDs myself that I need to get rid of. The ones on the left are classical, and rock is on the right. Plus I have a big box of CDs in the garage. I guess this is another retirement project.

Kitties are getting bigger and haven't clawed at the S55 grills in the bedroom system, so I figured it was time to go back to floorstanders. Found a pair of absolutely pristine LSI 15s for a nice price. If they leave these alone the 705s will be getting moved back in post haste. Try to ignore the kitty barricades.
I must say, at one time or another, I've owned 7s, 9s, and now 15s. The 9s, which I had on a pair of Sanus Ulimate stands prior to swapping in the 15s, were a better speaker. Listening 2 channel, no sub, the 15s have bloated flabby bass and lean way too much toward the bottom end. Anybody got a pair of Db840s they want to sell?
Hi, Dave. The 9's were my favorite in that lineup as well.

Not to be cliche, but this was a fairly substantial improvement. Micro detailing, staging, bass accuracy and impact.... I'm a frugal person and the money spent was worth it for sure. I run a passive line controller so my end result is pretty much up to my source.

Trey will either bring his down here, or I will bring mine up there sometime soon to compare the differences between a stock Tri-Vista and his modified. He is trying to talk me into getting mine done as well.
