I'd like to try a G5 as well, but they are D4 only so...nope. From others on here though, the G5 will br a lot better for SQ than an SE. I can't say as I haven't heard either one (just being honest) but supposedly the SEs are still pretty decent (more SQL though).
had both... NOT even a comparison.. G5 ALL THE WAY... actually I'd rather have a G5 than a XXX or an ID max also... 750RMS will be no problem for the G5.. its a REALLY nice sub... you should be very excited to have the opportunity to own one!
