Your KP201 really look nice! I don't normally see them in that nice condition.

Oh Man! I just blew the budget on a pair of Velodyne DLS-5000R. I may see if the wife is agreeable...

Nice HT speakers, for sure! Good prices, too.

Over the weekend, I picked up a pair of Velodyne DLS-5000R subwoofers. They have 15" drivers in a vented cabinet, forward firing, 600 watt class D, with some DSP eq. Since I use my KP301-B-Br as mains in my HT, these subwoofers compliment them nicely. I plan on purchasing the new Mad Max on Blu Ray tomorrow to really put my system through it's paces. While these may not be the best subwoofers ever, they were very inexpensive and are just like knew. The PO must have had $50k worth of HT gear in his house, so these might as well be straight out of the box. Now for an Academy center or a solo Heresy.

We will probably be heading up to Hot Springs for a family vacation Labor Day weekend. If so, we may be able to work something out on this speaker.

I am using an RC-7 for now. Someday, I will use an industrial Heresy.

I am in Rockwall - where are you?

FWIW, I have retuned my KP301 cabinets to a lower frequency - mathematically, they are tuned to 38 hz, by extending one of the ports into the cabinet. They certainly have a lower range now. I use mine for home theater/home stereo, so I don't miss any loss of SPL that may have occured by retuning the cabinets. With 125 dB @ 400 watts continuous, I felt I had room to sacrifice (heh, heh).

The HIP - is just a single available or a pair?

That depends on which cabinet they are in. I have a pair of KP301-B-Br in laquered blonde birch cabinets on short risers, no socket at all.

I tuned mine lower by adding a port tube extension [mo][]

Here are the T/S parameter for the K-48-KP: 05-RE OHMS 3.97 06-LE MH 1.17 07-QM 6.65 08-QE .370 09-QT .350 10-XMAX MM 5.50 11-BL TM 15.93 12-EFF % 3.21 13-FS HZ 41.93 14-MMS GMS 89.35 15-CMS mm/N .1612 16-RMS NS/M 3.5376 17-VAS LTRS 166.07 18-SD SCM 856.34 19-EBP 113.9 20-SPL dB 97.1 I believe I have these woofers in my KP301 speakers. I contacted Eminence and these are the numbers that they supplied.

They made the 301 as a home speaker? it was already a Cornwall/Chorus in the first place... I've had a pair of the road-handle versions for ages. Do yours have the tweeter-protection device on them? Mine have a lacquer birch finish without handles. They are a home version of the KP301. Mine do have two fuses on each cabinet for driver protection, one for the tweeter and I believe one for the mid. I am not sure and will need to look at the schematic again. I have not played around with the port tuning yet. I was wondering if I can install the ports from the front, rather than removing the woofer and installing them from the interior. That will make it easier for me to play with different lengths. But, they may not tune the same outside of the cabinet. Any thoughts?

It is supposed to rain here all weekend. If so, I will put off the automechanicing (is that a word?) and try to make some of these measurements.

I don't have an oscillator, but I do have a laptop with a simple signal generator program. Would that work? I haven't done a free air resonance test before. This method is something that I can handle, substituting my laptop and an amplifier for the oscillator. http://books.google.com/books?id=rv3vKxUwfQQC&pg=PA257&lpg=PA257&dq=free+air+resonance+test&source=bl&ots=Eo27kGKKH8&sig=697wBujzNrT44XUa_pCaYOBOSB0&hl=en&ei=ZILpS_23JIPGlQfD6ryMCw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CAsQ6AEwAA#v=onepage&q=free%20air%20resonance%20test&f=false
