tonewheels Posted November 13, 2015 Share Posted November 13, 2015 I've used an Ampeg SVT/8x10 combination for 35 years for rock, blues, funk and even, ahem, duo gigs. My back is finally saying "No more"! Spent a merry weekend playing with various combinations of SVT and Class D amps, SVT emulation fuzzboxes and 8x10, Barefaced One10 and Super Twin cabs. The One10 was a real star, giving real grunt on the floor and punch when raised to chest level. So, is the ideal lightweight medium power 8x10 replacement two One10s, One on the floor and one about 22" higher? If so, a really cool mod would be to fit a top hat flange on the top of one and on the bottom of the other. A bit of aluminium tubing and Bob's your male paternal sibling. Of course this would mainly effect only the near field. But that's where you're standing and, the better you sound to yourself, the better you play. The line array effects are the gotcha and need to do the trig on phase cancellations and augmentations in near (stage) and medium (pub) fields. Any thoughts, particularly from Alex, appreciated.

Guest bassman7755 Posted November 14, 2015 Share Posted November 14, 2015 You could try a cab on the floor angled up a bit, that essentially gives you best of both worlds, there are a variety of stands that do this, some also lift it a bit (but not enough to affect the floor boundary reinforcement). E.g. http://www.amazon.co.uk/SoundLab-Black-Adjustable-Monitor-Guitar/dp/B000O8QIJU/ref=sr_1_3?ie=UTF8&qid=1447496806&sr=8-3&keywords=amp+stand Quote Link to comment Share on other sites More sharing options...
JTUK Posted November 14, 2015 Share Posted November 14, 2015 I very much doubt it, but if you think so, good luck. Quote Link to comment Share on other sites More sharing options...
Chienmortbb Posted November 15, 2015 Share Posted November 15, 2015 AS far as I know the picture almost explains it. If you have stacked cabinets you get more output from mutual coupling. If you have one speaker on the floor then a "mirror image speaker is created that acts s a second driver so again you get higher low frequency output. I am not sure how far away the drivers need to be apart for these effects to diminish. Quote Link to comment Share on other sites More sharing options...
Happy Jack Posted November 15, 2015 Share Posted November 15, 2015 I suspect that stability might be an issue ... Quote Link to comment Share on other sites More sharing options...

From the colonial bass forum "Sources couple if within 1/4 wavelength of each other, whether they're in the same box or not, and the gain from mutual coupling of identical sources is 3dB. Four tens will realize 6dB gain over one, impedance and power notwithstanding" So if the cone centres were at approx 1m separation as I was suggesting, I'd lose 3dB above 75 Hz. Not good. Whereas if they're on top of each other they'd couple up to 200 Hz. Much more useful. Edited November 17, 2015 by tonewheels Quote Link to comment Share on other sites More sharing options...
MOSCOWBASS Posted November 18, 2015 Share Posted November 18, 2015 (edited) You could try an Ampwege between the lower and upper stacked One10's, this might be enough to direct the sound up towards you. I use a piece of plastic packaging to lift the front of my BB2 up, it makes a big difference. http://www.ampwedge.com/ http://www.talkbass.com/attachments/image-jpg.714838/ Edited November 18, 2015 by MOSCOWBASS Quote Link to comment Share on other sites More sharing options...

alexclaber Posted November 18, 2015 Share Posted November 18, 2015 I'd stack two and just stand a bit further from them! The off-axis response is quite a lot better than any of the SVT cabs so you don't need to be so much in the line of fire. Quote Link to comment Share on other sites More sharing options...
