Granite Subwoofer Top

Granite Subwoofer Top

I’m almost done building the second one of these. The minimalist construction (dowels bracing, single baffle), yields a somewhat light cabinet. Serving to both minimize the area I need to finish (coming soon), and to add significant weight to the enclosures, I will be topping them both with 3cm granite.   These will be cutContinue Reading

EQing the SI 18D2

EQing the SI 18D2

Build log for this sub begins HERE. With a 3.67 year old, the only time my house is reliably quite is at night. Last night was my third is the last week of evening spent making pink noise and sine wave sweeps. My wife is sweet to tolerate it. The first few times I will writeContinue Reading

Stereo Integrity HT-18D2 [design/build] 3 of 3

Stereo Integrity HT-18D2 [design/build] 3 of 3

Continuing from HERE. 12/19 – Attaching the dowels to the baffle I started by placing the baffle on the box – face up. Added the PL to the dowel, carefully avoiding the hole. Then lifted the baffle to put the dowel in place. I kept the baffle raised slightly until I got the bolt started,Continue Reading

Stereo Integrity HT-18D2 [design/build] 2 of 3

Continuing from HERE. Final non-baffle dowel installed. The driver cutout for the baffle is complete. The next step is to work on the dowels that will tie the driver to the cabinet – I need to make a jig to drill straight 3/8″ holes in the dowels to receive the threaded inserts.        Continue Reading

Stereo Integrity HT-18D2 [design/build] 1 of 3

Design complete. Cabinet will be constructed from a single layer of pre-veneered plywood from Menards. I had some left over from another project. All bracing will be from 1.25″ solid wood dowels. The net internal volume is calculates to 4.24 cubic feet. That includes .2 cubes as indicated by SI for the driver’s displacement. IfContinue Reading

Kenwood KA-5700 – Powder Coat

Kenwood KA-5700 – Powder Coat

Here are a few pictures of the powder-coated case. This was previously the stock black. The good folks at Sweet Williams Powder Coating were a big help. I was having a very difficult time removing the original black coating. The sand blaster I have at work wasn’t up to the task. They ended up usingContinue Reading

Kenwood KA-5700 Integrated Amp

Kenwood KA-5700 Integrated Amp

This is a little 40 wpc amp I picked up on Ebay to power my Overnight Sensations. It arrived in very good shape. All functions appear to work. The DC offset measured an acceptable 25 or 26 mV on all 4 outputs. That is a touch higher than ideal, but not something that needs immediateContinue Reading

Oppo Removes ISO Support for BDP-93 and BDP-95

Oppo Removes ISO Support for BDP-93 and BDP-95

It has been confirmed. The latest beta firmware released from Oppo strips the ISO support from both players, the BDP-93 and BDP-95, “Per the request from the studios”. I suspect the word “request” is an understatement. ————————————————– Release Notes: This version is designed for the OPPO BDP-93 and BDP-95 Blu-ray Disc players. Comparing to the previousContinue Reading
