Hi Folks, I readed a lot on this forum during the last fews days about overpowering or underpowering a cab but i'm still a little bit mixed up so i'm asking you some advice on wich cab should i choose. For the last 2 years i mostly played on an swr sm-900 with a Mark Bass Traveler 2x10 from one of my friend and i really loved the sound of his 2x10'' cabinet. But i retried my own bass amp that i didnt use for many years and i felt in love another time with its sound. Right now my own rig is an Eden WP-100 (Navigator pre-amp) plug into an Alto Mac 2.3 stereo power amp that deliver 310 watts RMS by channel in 8 ohms. My cab is an old Eden D115T but forget about the horn in it, it blew up over time when i was using this cab with an old Yamaha B100 head. This cab is rated at 200 watt RMS in 8 ohms. I would like to get another cab for more mids and highs because with the 15'' i feel the bass a lot but sometimes i'm lacking definition to hear the note that i'm actually playing. So i would like to buy a cheap but good sounding 2x10'' to use on the channel B of my power amp (bi-amped from the wp-100). My friend proposed me to bought his old yorkville bc 210 for really cheap but it's rated at 300 watt PROGRAM so if i understand, it's only 150 watts RMS right? Maybe a little to low for my power? So I was looking toward an ashdown mag 210 (rated at 250 watts RMS 8 ohms) or a GK MBE 210/8 (rated at 400 watts RMS 8 ohms) So my question is: should i go with a higher rated cab to go with the 310 watts per channel power amp or a 250 watts will do the trick? For now my Eden 15'', that is only 200 watts, sound amazing with this setup (i just have to be careful with the EQ and the power amp volume to avoid clipping). But i would like to get your opinion. If you have other cab to suggest, i'm open to hear about it. Thanks in advance! Btw i would like to apologize for my english, i'm a french canadian.
