B&W DM604 speakers

[flava30]

Thanks Swerd. Yes, I got the feeling that my pioneer is enough power. They sound really good. Especially with the SVS sub.

Lovinthehd-not moving them much except when I move into the new apt in a few weeks. They also look very nice . I really think that they sound clearer with the plugs though.

Swerd- the back says 150w amp max at 8 ohm. These are the first gens (96-99) The newer ones are at 200w amp max. But I think the pioneer is pushing them okay. But they might sound better with an amp.

I'm glad they got the job done. When you described how drilling made the old binding post get hot, I knew it couldn't be brass.

I couldn't find any info on the power requirements for your DM604s, but I'd be surprised if your Pioneer, rated at 130 wpc, is inadequate for them.

I'm late to this. However I have some comments. I would have used spade connectors.

The other issue is that I NEVER buy drill bits at a hardware store or big box stores. They are ALL junk no matter what the price. I buy all my drill bits off machine shops or specialist suppliers.

The next thing is that when drilling metal you need a drill that will turn really slowly. As you drill use cutting oil.

When ever possible use a drill press.

The basic rules are tough use only the highest quality drills. Use a drill that has good torque at slow speeds. Always use cutting oil as you drill.

TLS guy is spot-on about drills. As a machinist for over 40 years I'll confirm that many a brand new one, even one labeled "Vermont American" found in many hardware stores can have a very poor grind geometry. They may look OK to the untrained eye and make holes in wood OK, but to someone who actually makes a living with high performance drills in a machine shop...they are garbage. I might use one to pick metal chips out of the soles of my shoes, that's about it.

Cutting speed of drills made from HSS or HSS-Co (high speed steel or high speed steel with cobalt the tool steel material they are made of) is usually 30 to 100 surface feet per minute for most steels. That would be 727 to 2425 rpm. Most hand held drill (motors) run at either 1725, 3450, or vary between those. Some better battery powered ones may go slower.

I grab a lot of drills for my home shop off eBay. Look for brands Precision Twist Drill, Titex, Guhring, Michigan Drill, Ohio Drill, Nachi, Mitsubishi, Triumph, etc. There are a lot of junk drills with American or Japanese sounding names, found at Home Depot and others, such as Cobalt. A lot of the power tool makers offer "kits" of drills, often now with hex shanks. Those are almost all junk.

I definetly agree with both of you guys, but for the average Joe like me spending MONEY on a set of professional equiptment might not be cost effective like, for example, me on this little project. If I'd bought all those good tools and only used it once every few years if at all might not be worth it. Replacing the post was a simple cheap solution.

There are sellers who offer sets of quality drills for a fair price, such as Travers Tool who is in your area. Invest once in quality to start, replace the most used ones singly as they get worn. If you know someone (such as me) who has a drill grinding machine to recondition them, never even replace drills unless you break them.

One such set: http://www.travers.com/precision-dormer-jobbers-length-twist-drill-set/p/01-300-381/

Most homeowners and even many renters need to make holes. It can be a repair, it can be pilot holes for wood screws, mounting something on a wall, building a bookcase, so many times you may need it. This is evidenced by the fact that you have a drill motor and at least a couple of questionable quality drills.

All said, your solution to this one was the right thing to do for you. If you had a good 5/32" drill at the right speed and knowledge you have now, you might have been plugging in the banana plugs a long time ago.

Please don't go down that wire/cable rabbit hole (if a connector of convenience has convinced you of improved sonics....). Might want to read something like this http://www.roger-russell.com/wire/wire.htm

Point taken guys. Thanks.
