Am I... Asking the impossible???

One thing DOES make a small combo better than a big-rig for practice; fan noise.

If the big rig has a big fan that whirrrss away it can become annoying at low volumes. A small amp may have a quiet fan or even no fan.

I run a GK MB-115 driving a home-stereo style speaker (10" woofer, sealed box, 1" dome tweeter). It sounds great through that speaker; better than through the built-in 15" speaker. This pic shows it with my old Shuttle 3.0 which has been replaced with the GK combo. But I'm still using the speaker.

But difference is based on SPL level, not the power level of the amp. A small amp played quietly won't sound any better than a big amp played quietly.

Killjoy. Next time you manage to take someone else's comment out of context to make some astute seeming point, with or without a Wikipedia link, I hope someone does the same thing to you so you see how it feels :laugh:
 
I do not think it is meant as a joke. I have a Gallien Krueger 800 RB pushing 300 watts and a Traynor SB500H head pushing 500 watts either one of those hooked to a Hartke HD 112 cabinet. I live in a two bedroom apartment. My rig is in the living room. I sit at 90 degrees to the speaker; 2 feet away from the cabinet and I turn down and it is just fine. I find the tone much more satisfying that using a 25-50 watt combo amp.

I continue to post because, for some reason, I just can't look away...

The op simply wants to get a combo...I don't think there's much more behind it than that

- Turn down what you have (No. I don't like how "big amps" sound at low volume)
- If the cabinet is the untamable "big" thing, get a small cabinet and use it with one of your amps (No. The amp is still big. Old Peaveys need to be cranked)
- If the power on tap is the untamable "big" thing, get a low powered head (No. The cabinet would be too big)
- Headphones (No. I need to be aware of my surroundings)
- So, you want to play really quietly, huh? Well, how about a true practice amp? (No. An 8" speaker can't handle my low A string with any authority)

I tried one of those little Ampeg 25 Watt practice amps. The idea was to have something I could leave set up in my music room to practice through. If that thing genuinely put out a solid 25 Watts RMS at 20 Hz., then yes, it would have been okay providing the loudspeaker / enclosure / tuning was adequate to produce some low bass. But no, no and no. Not. Nothing will convince me that thing put out any where near 25 watts of real power across the audio spectrum, but particularly not down in the low bass.

As a comparison, half of a Dyna Stereo 70 (35 Watts RMS) will rock your world in a practice room (you have to use a bass preamp) if the cab is relatively close to your head on a stool or something, even through an inefficient small loudspeaker provided it has some true bass response (such as my Acme Low B112FR).

Next I tried another combo with a 12 inch speaker, 100 watts, I think. It did okay I guess until I wanted to play below let's say the low F# or E on my five string, at which point it just seemed to run out of juice even at low volume. Didn't sound good down there. I should have tried the 15 inch Rumble. But I didn't. Wasn't checking out TalkBass back then.

By that time I was frustrated and I happened to visit GC to pick up some cords and saw an Ampeg SVT 7Pro in the bass room. That's a GC story in itself but to make a long story short, I now have an SVT 7Pro and an Acme Low B112FR that lives in my music room, and it works great! Well, it worked great until the aux power supply controller chip exploded in the SVT 7Pro which almost blew me off my stool since I have the cab on another stool right next to me when I practice! That's all worked out now. Thank God Yamaha acquired Ampeg! Anyway, even at 2:00 AM which always seems like a pretty good time to practice, I don't bother my neighbors in the Condo at the volume I play at and I get beautiful low end response that is very satisfying and inspiring. Then again, I'm not playing Viking metal, either. But I would say quality is quality and it makes a difference no matter what volume level you may be playing at.

I already addressed the OP's other issue.

You mean cheap practice amp w/ short throw voice coils in an under engineered box regardless of driver size.
Several 8" Studio monitor subs do just fine at low volume.
A true practice amp is a hi fi monitor kit in a single tuned box.
My little 5 inchers don't show a hint of struggle with "A"0.
A pair sound w/ 70w sounds great at quiet volume still really pumping those lowest notes!
All 8 or 10 of them w/ big amp at same quiet volume (according to cheap db meter) isnt as full down in the lowest register...
So once again just catering to that Fletcher-Munson curve however possible is the goal.

Whaaa:wideyed: Thank you for reminding me this form and prob. the whole world is prob. just a cosmic hidden camera show! Thats hilarious:roflmao:
How ridiculous is that! Merriam-webster actually bothered to define that non-colloquial word phrase?
The definition from Webster's. An institution I havent respected or acknowledged since highschool came up with exactly the same words as I did!? I still lauged until my sides hurt. On the other hand creepy... either I'm just that dry and clinical and or I actually can't believe thats published and I'm too spooked at the moment to look for myself. Sounds like a google addvert? based on what was on your screen. :eek: guess I'll show this to the next person calling me a walking dictionary.

You may be right there. But... It is well known among audiophiles that are into vacuum tube amplifiers that said vacuum tube amplifiers sound warmest when operating at power. That's why there are 5 and 10 Watt vacuum tube hi-fi amps.
