Better put some orange warning signs on that pole outside your door...someones gonna try and push it aside...but the poles usually win.

I'm not too worried about that 60+ year old cedar telephone pole, it's about 2' onto the neighbors lawn and I've learned to avoid that brittle old thing. :D
 
Oh I forgot to mention I also added a 250 watt 10" Pioneer Premier home theater sub woofer to my stereo. :dance:

Hey, I've got one of those lying in my basement. The power supply is melted out of it... one of seven amps I grenaded that year. :D

The Sony was bigger and far-more robust, but it couldn't take the pressure either.

I bought this one about 5 years ago from a pawn shop for $100 with a blown out driver, put a nice 10" Phoenix Gold sub in it and it's been pounding the bass ever since. :dance:
 
Actually, I was commenting on your receiver, not the sub. :doh:

Using a sub with my garage speakers would be absolute overkill. With 12" woofers and the cabinets ported to ~75Hz, I can crack house windows with them 6" from the wall feeding them only a little more than 60W each. I haven't had much chance to crank it since I got the dog, though. :D

Ah, The amp is an old brute, 450 watt RCA home 5.1 theater amp with bridged stereo function I picked up for $175 at a pawn that used to be in my living room until the optical audio input died and the preset equalizer refused to work on anything other then "Flat", so after manually enter equalizer values and going to just RCA's for input it works perfect in the garage. I upgraded to a 500watt Sony with an HDMI splitter, beautiful and very powerful amp for $250, gotta love boxing day sales! :dance:

The speakers are a pair of old Technics rated at 240watts RMS each with 10" subs, 5" mids and 2" dome tweets, they sound great and the subs are crossed over so they are a fuller range then just being a sub so they are LOUD but lacking deep bottom end thump, ergo the powered sub. :D

I assume you mean they're not crossed over? If they were hooked to crossovers--and I'm betting they have a small frequency-limiting network but not an actual crossover, they wouldn't be so full-range. Not trying to sound like a jerk--trying to educate. I'd bet with actual crossovers, and a bad day at work, you could rip the surrounds on those older woofers. Ask me how I know.

The large speaker in a cabinet is not a sub, it's a woofer. The idea of a subwoofer is that it can literally spend more effort on lower frequencies than the woofer in a full-range cabinet design simply because it's got a tight crossover, usually at or below 150Hz and a minimum of 12dB/octave for home applications. In cars, they often suggest a "gap" in the low-frequency area between 80Hz and 120Hz, since in that range the chassis is a natural resonator and self-amplifies.

If you're happy with your setup, fantastic! I don't mean to criticize; it's not my intention whatsoever. Stereos are one of many hobbies of mine, and since I've never been wealthy I've had to do it all on a budget. I've destroyed a lot of components over the years because I run 'em way harder than most... and with that loud-ass compressor I used to have, I had to really run it hard in the garage!
 
Not at all Jass, I'm not versed in the proper terms. :D

I play with audio stuff too as I love playing music and having it sound good, but I only know a little as I haven't spent the time to learn.

I'm sure those cabinets will have resistors or some kind of filter wired in as the woofers are not completely full range.

Constructive criticism is just another term for "helping out". :D
 
There are pictures here somewhere--or there used to be--of the 250V capacitor that exploded on one of my crossovers. To quote Curly from The Three Stooges, "I fall down and go boom!" I had it so loud at the time, I didn't hear the firecracker sound of a capacitor letting fly. :doh:
 
Building your own speakers is a lot of fun, especially now that all the math I used to do on pen and paper can be wrapped up by a simple program like WinISD.

It's a lot of fun to blow store-bought speakers costing a lot more money than what you've invested right out of the water. Badly. :dance:
 
A couple more small improvements.


A place to sit.

And a place to wash the grimy bits I took off my Dakota. :D A plactic tub from Canadian Tire and the bottom half of the old SUN Interrogator II from the shop.
