I own a 4pro and a svt410hlf, does anyone here mono-bridge this setup? Sending 1200watts into the 410HLF?
I'm lacking some power and so i'm thinking of upgrading to a 610hlf or isn't it safe to mono-bridge it with the 610?
been wanting an answer to this question for quite some time, so i think here's the ideal place to ask
I didn't see where anybody answered your question. Don't do it. There's enough power to fart out an HLF with just one channel of a 4PRO and it's way too easy to blow up one with the full deal.
You state you need more zoom, then buy another HLF and stack them. Run one side to each cab and you will be louder than even an 810.
The 610 I haven't used one, but most guys do run bridged to them.
A 4PRO has enough power to fart out an 810 so you be the judge.
I do have a 410HLF for sale, hint... But that is not my reason for stating get another one. I didn't look where you were at, but probably too far for mine.

i run my pro 6, thru my 610hlf, 1100w i think but have it cranked to say bout 3/4 doesn't fart it out.
i'd love to have a 2 ohm head and get to of the 610's i love em. but i have to agree just feed 2x410 of each side of the head.

yeh im getting it as a small band practice and home amp, its a bit excessive but i prefer the tone to the combos

To answer your question...
RMS is an average power.( Root, Mean, Square) you should look at the cabs program ( peak power) for better cabinet/amp matching.
I run 2 Svt 810's from a 3000 stereo watt amplifier that pumps 1500 watts at 4 ohms into each cabinet. The 810's RMS power is 800 watts, but the program power is 1600 watts. As you can see, I'm running these cabs real close too there limit but that's what there made for.
Your 410 hlf is rated at 500 watts RMS or 1000 watts program or peak (you can verify this on the spec label behind the cabinet) so your amp at bridge mono may overload the speaker cab at it's peak power output and eventually could lead to speaker failure. The 610 cab is rated at 1200 watts program, or 600 watts RMS. this will be fine with your amp. But remember in bridge mode, you can't have a speaker load less than 4 ohms, so you can't add any more cabinets but you will get the most output from your amp running this way.
One thing to consider, running the amp in bridge mode produces more heat. If you have this amp in a rack, you will need to cut out some 3 or 4 inch side vent holes for the fan or the amp may shut off until it cools. Your best bet is to not rack mount it when using it in this manner. Also be sure to use the correct bridge mono cable or you can damage your amp. You must use an Neutrik speakon connector w/+1 +2 wiring that plugs into the amps speakon output going to a Neutrik speakon connector w/+1 -1 wiring or a mono 1/4 inch jack plugging into the speaker cab. Ampeg should have given you one with your amp.
I think the 610 or 810 would be a good choice. the more speakers will produce more sound and the mono bridge power would definitely give you the power increase your looking for!
You will not blow up your speakers running the "full deal". It is true that the more speaker cabs you run, the more the sound is dispersed giving you a greater sense of stage volume even though the wattage per speaker cab is less than running 1 cab in bridged mode. So this is something too you need to consider before you buy another cabinet. As for stacking them or splitting them on stage, I prefer stacking them or keeping all the bass cabs on one side. This is subjective to one's own opinion so you should try it for yourself and use your best judgment.
In my opinion, if you don't need a tweeter, go with a 810( which is really like two 410 cabs stacked together) and run it in bridge mono and that will give you 1200 watts into 8 speakers at 4 ohms which will be a little more powerful setup than two 410 hlf's in dual mono which will be 490 watts total per cab at 4 ohms. (remember you can't run more than one of these cabs in bridged mono because each cab is 4 ohms and two cabs will give you a 2 ohm load and that's a no-no in bridged mode). However, a 2 ohm load such as two 410's daisy chained into one channel, your amp will put out 600 watts, but since the wattage divides equally, each cabinet will receive only 300 watts which you can see is a little less than two 4 ohm cabs directly plugged onto separate channels.
If you prefer the tweeters, then keep what you have and consider a 610 and run it dual mono and you'll get the 490 watts out at 4 ohms from your amp to each cab. even better, two 610's would give you a even balanced look and a total of 12 speakers, same wattage out, more speakers, more sound. If money is not much of a concern, go with four 410's or 610's and run them two cabs per channel (daisy chained) for a 2 ohm draw per channel. You will be drawing only 300 watts per cabinet this way, but with all those speakers you will have the stage volume your wishing for.
Am I confusing you yet?
If your still not sure of this, you can verify the cabinets max rating at Ampeg .com tech support via e mail or call Tel: +1 866 858 LTEC (866 858 5832) and they are real good at answering all your questions.
Bob, I have always used the term "fart" to describe the noise caused by port turbulence, but I think you're using it to describe the noise caused by exceeding the excursion limit of the drivers? So a bridged 4Pro can bottom out a sealed 810? Awesome!
Easy...it's the one on the left. Built of thinner plywood with non-wrap around corners, they're easy to spot.
Congrats mkandolf on your new Ampeg BA115HPT! I would like one of those for a nice practice amp. I am debating on this one or a Ampeg Micro-stack.
WE sure can't get one by on you! If you look at the full picture, you can also notice the Nam-Peg version has a little larger grill cloth because the thinner wood, and also the Ampeg logo is mounted a little bit higher than the SLM series and crooked too.
Don't know much about the microstack
but I've had a BA115HPT since last November and it's the sweetest small amp I've ever heard. It comes with caster so it's very portable and it's got pretty decent power(220W). I use it for a practice amp (SVT4Pro and 810E for a gig amp) and for about $650, I'm completely satisfied.
That's a rockin stack...very cool!
I originally ordered one of the last SLM series 810's, but unfortunately, I received a Nam-Peg version instead. I decided to keep it anyway. I have to tell you though there is a slight difference in tone which I believe is due to the differences in woods used for the cabs. I find it to be slightly brighter, or not as boomy as the SLM version. Since I use two cabs, I think this gives me a nice blend. Another Forum member who seems to be very knowledgeable on Ampeg products wrote the Vietnam versions are made with real plywood and the SLM's are made with OSB (particle board). I'm not sure, but OSB seems like a cheaper lower quality material to me. I do understand the significance of American made products and I own many, but a lot of us do own foreign made items by foreign companies. (i.e. Korg, Roland,Yamaha, Electro-Harmonics, Russian and Chinese tubes for our amps, etc.) So one or two pieces of gear that isn't American made doesn't dwell on my conscience too bad.
