is that 105 watts rms, peak or per channel?

if it’s rms like i would imagin with a hi-fi amp, with 4×25 watt speakers if you get a bin then you will probably just drown them out .. also i doubt your amp will sound that good running that many speakers at that wattage and you may even damage it

i would go for a nice pair of full range studios @ about 50 watts a piece and then mby get another amp and bin if you got the cash … i got 2 3 way full range cabs @ 200 w each just on the base and that’s running off a 200 rms or so amp really sounds nasty if i get anywhere near half volume .. but then tbf i don’t need it that loud .. but i am thinking of downgrading my upgradings to some nice studio speakers as they sound better at lower volumes and can still kick some out when you want them to

Buy a bass bin/something large and powerfull to really get the ground shaking EG .. – Kam Extreme15S [Catapult 100% Vinyl – Online Dance Music Shop] .. (not sure how my amp would handle this? may need to upgrade that too?)

Trouble with just bolting a sub onto the system is you need to be sending just bass to it, rather than the full range signal that you’ll get out the back of the amp, so you’ll need a crossover. Also that sub is a 400W PA speaker, so your 105W hifi amp wouldn’t be suitable.

If you just want to add some cheap and dirty bass to your system maybe look on ebay for an active home cinema-type sub. They have their own crossover and amp built in so you don’t have to worry about how it will fit with the rest of your system. The input is normally on a pair of line-level phono sockets (or a single phono) and will connect to the “pre-out” or “sub” on the back of your amp. You can pick one up for about £30. They won’t go massively loud, but should be good enough for your bedroom.

Buying a pair of bigger full-range speakers with a decent bass response is a better option if you want to fork out (look at manufacturers’ websites for a frequency response plot before you buy if bass is what matters to you). Note the Behringer speakers you suggest are active, so you won’t need your amp to drive them (if you need to keep your amp to switch between sources i.e. tuner/cd/computer/decks and it doesn’t have a pre-out (line-level output) active speakers might prove a pain in the arse).

Thats a nice setup what kind of mixer have you got?
Yeah my amp is 105 watts RMS i think. if i wer to go for the bin i reckon id get rid of my four 25 watt speakers and only use the bin, also id have to buy a better amp i guess. could be a bit pricey..
if i wer to go for option 2 and buy the studio monitors would i be able to keep using my current amp and four speakers without a prob??

if you was to get studios and use your 4 25w ones aswell you wouldn’t be able to power them all properly i wouldn’t think so i’d just have the monitors… and if you was to only have a bin then it would sound shit as you wouldn’t have any higher frequencys and it would sound like your listening to next doors music instead of yours …

the idea about getting an active sub that you find with suround sound systems is also a good one imo you could link this up with either your 4 speakers or some studios …
