Im just starting out really. I had a UMIk1 for 2 years but only dug into REW last month again since I got the MiniDSP DDRC24. I gotta say I dont have the patience to go through endless measurements. But the SVS I tamed very well. Treating the room alone made such a big difference in measurements. I actually had little to correct after that.@Pieter1267 how good are you with DSP processing (EQ-ing) and do you have any? Every enclosure has it's advantages and disadvantages. The purpose of the port is to reinforce or introduce what woofer can't do. Unfortunately all home speakers ports tunings are done in the mater that port's cuff out a lot under what woofer actually can. Only some very good PA subs are done in the right way that the port supports lower limit of what woofer does pushing it's actual response not a cuff in front. They are loudest but port must have enough space to maintain flow without obstacles and they do lose function (flow) at certain SPL (and regain it going higher or lower). Closed enclosure requires big in volume box in order to have more extension but it's still usually smaller than ported one. Only the driver does the work and compression of the box help's a little bit. They roll out gradually in lower slope (dB/octave). Not so loud and a bit more of control and of course less extension on the bottom. Open buffle is well open and uses actual room as a box. Behaves much like closed buffle but goes a little louder but introduces it's own fair share of problems like lack of separation in combination with bad back to front refractions timings.
All of this doesn't matter much. You will use ported mains and they won't have same slope as closed box ones even if you block the port's they will get somewhere in between. But you don't need and want to kill it anyway and obstructing (plugging) the ports help there (and so does DSP in much more ways). When you do it high enough where woofer does it easy on it's own you lower the pressure on it and with it you gain lower THD on same SPL or a bit higher max SPL without distorting bad. All do it's just couple of dB sometimes even couple is not so little (±12 dB is psy 2x and ½). You let subs play what you cut to what they can. Amount of sub's they size do you want it to get physical or not (neighbours certainly don't) is discussable and so is the low - sub bass tail but what isn't is a 105 Hz knee (self filter) for psy equal loudness compensation which is important so that you don't have to turn the hause down or go deff (or blind) and cetera wanting to have that full range feeling pushing it very loud. As it pushes the bass up significantly so you may have it even on the level of common talk for the rest. It also boosts highs a bit but only on low volume. It won't be great on really low volumes but on normal ones (mid 70's programme normalised) it work's pretty good. As you go over 88~90 dB programme correction for equal loudness actually scales another way around (reducing bass).
If you like Revel's and have a "good bargain" on them go for it. Linton's will do it just fine on the other hand. Then we can talk 4 ways wide with super tweeters as bright as a sun to widen and reinforce small ones in all home speakers.
And with that I also hope to get a home test. I called some dealers and some are great, willing to give me a 1 or 2 week testrun in my room, with my amps. But then Im also bound with dealer prices. The Revels new are just way out of my league and given the huge slashing of prices, and the BIG differences between USA and EU prices I feel there is too much sticking in between.
Wharfedale is fair though, and I can order directly. They have a 14 day try period you can use to make up your mind. But Im in Poland in 2 weeks and I know a nice used Revel F208 close to the border in Chech republic. Who knows. I havent auditioned the F208 yet and they arent on offer at the dealers anymore. Spending 3k on speakers you never heard is kind of unwise. We will see. Im in no hurry.
